I have the following code and I need to know why I am receiving the .pdf
Edwards Manufacturing Company purchases two component parts from three different suppliers.
The suppliers have limited capacity, and no one supplier can meet all the company’s needs. In
addition, the suppliers charge different prices for the components. Component price data (in
price per unit) are as follows:
Each supplier has a limited capacity in terms of the total number of components it can supply.
However, as long as Edwards provides sufficient advance orders, each supplier can devote its
capacity to component 1, component 2, or any combination of the two components, if the total
number of units ordered is within its capacity. Supplier capacities are as follows:
If the Edwards production plan for the next period includes 1000 units of component 1 and 800
units of component 2, what purchases do you recommend? That is, how many units of each
component should be ordered from each supplier? Round your answers to the nearest whole
number.
What is the total purchase cost for the components? Round your answer to the nearest dollar.
$ ????SupplierComponent1231$11$10$132$10$11$11
Solution
For component 1:
supplier 2 have minimum cost and capacity 1050.
So all the component 1 (1000) can be purchased from supplier 2.
So, supplier 2 have 50 more capacity.
Now, supplier 1 have minimum cost for component 2 and have capacity of 650.
so, number of component 2 from supplier1 can be 650.
Now, we need 150 more component 2.
supplier 2 and 3 have same cost for component 2.
supllier have only 50 capacity now and supplier have 850.
So, 150 component 2 can be purchased from supplier 3.
Let y be the number of components fromSupplier123TotalcostComponent

Need help getting past an error in C++! I have all my code pasted down.docx
Need help getting past an error in C++!
I have all my code pasted down below. My issue is that I'm trying to call the functions I have in main, but they don't do anything as they are now. I'm almost positive I need to call them with parenthesis, but putting them in always results with an error saying "A nonstatic member reference must be relative to a specific object."
Below will be the source file, then the header file I made all the functions in. Thanks in advance, y'all are the best!

I have the following code and I need to know why I am receiving the .pdf
Edwards Manufacturing Company purchases two component parts from three different suppliers.
The suppliers have limited capacity, and no one supplier can meet all the company’s needs. In
addition, the suppliers charge different prices for the components. Component price data (in
price per unit) are as follows:
Each supplier has a limited capacity in terms of the total number of components it can supply.
However, as long as Edwards provides sufficient advance orders, each supplier can devote its
capacity to component 1, component 2, or any combination of the two components, if the total
number of units ordered is within its capacity. Supplier capacities are as follows:
If the Edwards production plan for the next period includes 1000 units of component 1 and 800
units of component 2, what purchases do you recommend? That is, how many units of each
component should be ordered from each supplier? Round your answers to the nearest whole
number.
What is the total purchase cost for the components? Round your answer to the nearest dollar.
$ ????SupplierComponent1231$11$10$132$10$11$11
Solution
For component 1:
supplier 2 have minimum cost and capacity 1050.
So all the component 1 (1000) can be purchased from supplier 2.
So, supplier 2 have 50 more capacity.
Now, supplier 1 have minimum cost for component 2 and have capacity of 650.
so, number of component 2 from supplier1 can be 650.
Now, we need 150 more component 2.
supplier 2 and 3 have same cost for component 2.
supllier have only 50 capacity now and supplier have 850.
So, 150 component 2 can be purchased from supplier 3.
Let y be the number of components fromSupplier123TotalcostComponent
1010000100010000Component 265001508008150Total cost18150.

Need help getting past an error in C++! I have all my code pasted down.docx
Need help getting past an error in C++!
I have all my code pasted down below. My issue is that I'm trying to call the functions I have in main, but they don't do anything as they are now. I'm almost positive I need to call them with parenthesis, but putting them in always results with an error saying "A nonstatic member reference must be relative to a specific object."
Below will be the source file, then the header file I made all the functions in. Thanks in advance, y'all are the best!

Explain why multiple processes cannot share data easilySolution.pdf
Explain why multiple processes cannot share data easily?
Solution
threads share C.P.U. and just one thread active (running) at a time.
threads among a processes, threads among a processes execute consecutive.
thread will produce youngsters.
if one thread is blocked, another thread will run
hreads don\'t seem to be freelance of 1 another.
all threads will access each address within the task .
thread square measure style to help one alternative. Note that processes would possibly or may
not assist each other as a result of processes could originate from completely different users
A method with multiple threads build a good server for instance printer server.
Because threads will share common information, they are doing not have to be compelled to use
interprocess communication.
Because of the terribly nature, threads will cash in of multiprocessors.
They solely want a stack and storage for registers thus, threads square measure low-cost to form.
Threads use little resources of associate degree software system during which they\'re operating.
That is, threads don\'t want new address house, international information, program code or
software system resources.
Context change square measure quick once operating with threads. the rationale is that we tend
to solely ought to save and/or restore computer, SP and registers
User-level threads doesn\'t need modification to operative systems.
Simple Representation:
every thread is depicted just by a computer, registers, stack and atiny low management block, all
hold on within the user method address house.
Simple Management:
This merely implies that making a thread, change between threads and synchronization between
threads will all be shunned intervention of the kernel.
Fast and Efficient: Thread change isn\'t way more overpriced than a procedure decision.
There is a scarcity of coordination between threads and software system kernel. Therefore,
method as whole gets just one occasion slice irrespect of whether or not method has one thread
or a thousand threads among. it\'s up to every thread to relinquish management to alternative
threads.
User-level threads needs non-blocking systems decision i.e., a multithreaded kernel. Otherwise,
entire method can blocked within the kernel, albeit there square measure runable threads left
within the processes. for instance, if one thread causes a page fault, the method blocks..
executive summary for law enforcement using dronesSolutionUse .pdf
executive summary for law enforcement using drones
Solution
Use of drones makes the job of law enforcement easier as it enables access to real time
surveillance. Drones helps the police force conduct aeriel surveilance and the video can be
viewed real time or at a later point in time. This is a very useful tool during the investigative
process. Drones can be equipped with thermal cameras so as to keep an eye on anti-social
elements.
However, law enforcement agencies will have to make sure that use of drones do not violate the
privacy of citizens..

Explain why multiple processes cannot share data easilySolution.pdf
Explain why multiple processes cannot share data easily?
Solution
threads share C.P.U. and just one thread active (running) at a time.
threads among a processes, threads among a processes execute consecutive.
thread will produce youngsters.
if one thread is blocked, another thread will run
hreads don\'t seem to be freelance of 1 another.
all threads will access each address within the task .
thread square measure style to help one alternative. Note that processes would possibly or may
not assist each other as a result of processes could originate from completely different users
A method with multiple threads build a good server for instance printer server.
Because threads will share common information, they are doing not have to be compelled to use
interprocess communication.
Because of the terribly nature, threads will cash in of multiprocessors.
They solely want a stack and storage for registers thus, threads square measure low-cost to form.
Threads use little resources of associate degree software system during which they\'re operating.
That is, threads don\'t want new address house, international information, program code or
software system resources.
Context change square measure quick once operating with threads. the rationale is that we tend
to solely ought to save and/or restore computer, SP and registers
User-level threads doesn\'t need modification to operative systems.
Simple Representation:
every thread is depicted just by a computer, registers, stack and atiny low management block, all
hold on within the user method address house.
Simple Management:
This merely implies that making a thread, change between threads and synchronization between
threads will all be shunned intervention of the kernel.
Fast and Efficient: Thread change isn\'t way more overpriced than a procedure decision.
There is a scarcity of coordination between threads and software system kernel. Therefore,
method as whole gets just one occasion slice irrespect of whether or not method has one thread
or a thousand threads among. it\'s up to every thread to relinquish management to alternative
threads.
User-level threads needs non-blocking systems decision i.e., a multithreaded kernel. Otherwise,
entire method can blocked within the kernel, albeit there square measure runable threads left
within the processes. for instance, if one thread causes a page fault, the method blocks..

executive summary for law enforcement using drones
Solution
Use of drones makes the job of law enforcement easier as it enables access to real time
surveillance. Drones helps the police force conduct aeriel surveilance and the video can be
viewed real time or at a later point in time. This is a very useful tool during the investigative
process. Drones can be equipped with thermal cameras so as to keep an eye on anti-social
elements.
However, law enforcement agencies will have to make sure that use of drones do not violate the
privacy of citizens..

create a narrative budget blueprint for a local unit of government. .pdf
create a narrative budget blueprint for a local unit of government. Put yourself in the shoes of an
administrator in a newly formed municipality that has never developed a municipal budget
before. How would you complete the task? Where would you start? What process would you
follow? Who would be involved? What concerns do you have, how do you resolve them? How
do you budget for capital items and link them to the operational budget, etc.? Be as detailed as
possible to display a comprehensive understanding of the course material.
Solution
Municipal Budget :
A municipality is a general-purpose administrative subdivision. It is an urban area usally a city or
town .
Generally Municipalities create Budget on Annual basis. Budget consists of anticipation of
Expected Revenue and Estimated Expenditure.
Generally we start from
a) Revenue :
i) Revenue may be Grants received from Central Government for specific purpouse or general
purpouse.
ii) any local taxes collected from individuals etc will become revenue .
b) Expenditure :
As it is newly formed local unit it can take the basis of any muncipality which is already existing
so that it can cover all administrative expenses like electricity, water, Telephone charges etc.
Sometimes expenditure may be Planned or Unplanned . Therefore amount should be kept aside
as Contingency for UNplanned portion.
Proper authorisation should be there for each and every expenditure.
Expenditure may be for salaries, maintenance of road ways, public parks ,libraries or to provide
Safety services for public, funds for Schools etc
While preparing Budget there might be conflict of ideas.It can be overcomed by meeting the
concerned head of the department.
For Capital budgets Proper Approval, Sanction details Should be verified.
Every member in the unit should be aware of Guidelines respective to there Department.
Through which errors can be avoided.As requisition and payment process done from the unit ,
there should be proper segregation between CApital and revenue expenditure.This can be done if
there are seprate Rules and guidelines for capital and revenue expenditure.
So, in Budget major Focus will be on Revenue and Expenditure..
define three types of kernal-mode to user mode transfersSolution.pdf
define three types of kernal-mode to user mode transfers
Solution
1.Multitasking ; In order to excute multiple jobs , process switching is needed some times.In
order to load programmes CPU moves from kernal mode to user mode
2.Interrupt handling ; Modern architectures are interrupt driven.When an interrupt occurs, the
hardware automatically switches a part of the context (kernal-mode to user mode or usermode to
kernal-mode)
3.User and kernel mode switching ; A transfer between user mode and kernel mode is required in
an OS, then user and kernal mode switching takes place ..

C++You will design a program to play a simplified version of war, .pdf
C++
You will design a program to play a simplified version of war, using dice instead of cards. There
will be only one user, but 2 “players” for the game. The user will indicate the number of rounds
to play. The user will also specify for each “player” the number of sides on the dice used and if
that player is using regular or loaded dice. For example, one player could have a loaded 10-sided
die while the other has a 4-sided die. User should be able to determine how \"loaded\" the die is -
2/3/4 etc times mores likely to return a high number.
To play the game, for each round, you roll a die of the appropriate type for each player. The
higher result wins. If the results are equal, it is a draw. The winner of the game is the player who
won the most rounds. Your program will print out which player won to the user.
Die class: requires an input integer N which determines the number of sides on the individual
die. It includes a method to return a random integer between 1 and N as the result of rolling the
die for once.
LoadedDie class: it inherits the behavior and elements of Die, but the number it returns is biased
such that the average output of rolling it for several times will be higher than for a Die object.
You can determine how you want to realize the biased function.
Game class: it will implement the simple dice-rolling game. In the menu function, the user will
specify the die sides used by each player (the players can have dice with different number of
sides). The user will also indicate if either or both players are using loaded dice, and will enter
the number of rounds in the game. The Game class will create the necessary objects, play the
game, and display the results to the user. The output results should indicate the side and type
(loaded or not) of die used for each player, the number of rounds won by each player (in each
round, compare the rolling results, the larger number will win), and the final winner of the game
(the player that win more rounds).

2.How important is it to involve physicians in financial improvement.pdf
2.How important is it to involve physicians in financial improvement efforts? What is the best
strategy for physician engagement?
Solution
Physicians are the key player in healthcare system. They have expert knowledge, skills , abilities,
experience, opinions etc. to suggest for formulating the policies related to healthcare
improvements practices. They actually know what is equitable, suitable, right , fair, transparent
and realistic pricing startegies for patients care as well as their payment part in the health care
system.
To engage the physician in healthcare system, the following efforts must be developed and
implemented by the hospital management and healthcare administrators,
1) They should have to report on daily basis to some central authorities related to their day to day
contribution.
2) Their payment and compensation should be kept best among the industry so that they do not

3) They should be given some startegic role to analyze the best practices prevalent in the health
care industry.
4) Some training and development activities for future doctors and staffs must be organized by
the hospital so that these physicians can contribute their learning and experience.
5) They should be asked to write some blogs on social platforms so that more people can be
attracted for health care reforms and services offered by the hospital.
6) They should be given some flexibility to choose their plan for making and earning money by
being the part of the helath care system.
7) They must be engaged for setting code of ethics for health care reforms and quality conscious

Write one page essay to explain how you relate signals and systems theory with current
technology advancement.
Support your argument by providing a case study and identify signals and systems theory plays a
major role on mentioned application.
Please post the website or database you found information. Thank you!
Solution
A signal as referred to in communication systems, signal processing, and electrical engineering is
a function that \"conveys information about the behavior or attributes of some phenomenon. In
the physical world, any quantity exhibiting variation in time or variation in space (such as an
image) is potentially a signal that might provide information on the status of a physical system,
or convey a message between observers, among other possibilities. The IEEE Transactions on
Signal Processing states that the term \"signal\" includes audio, video, speech, image,
communication, geophysical, sonar, radar, medical and musical signals.
Typically, signals are provided by a sensor, and often the original form of a signal is converted to
another form of energy using a transducer. For example, a microphone converts an acoustic
signal to a voltage waveform, and a speaker does the reverse.
The formal study of the information content of signals is the field of information theory. The
information in a signal is usually accompanied by noise. The term noise usually means an
undesirable random disturbance, but is often extended to include unwanted signals conflicting
with the desired signal (such as crosstalk). The prevention of noise is covered in part under the
heading of signal integrity. The separation of desired signals from a background is the field of
signal recovery, one branch of which is estimation theory, a probabilistic approach to
suppressing random disturbances.
Engineering disciplines such as electrical engineering have led the way in the design, study, and
implementation of systems involving transmission, storage, and manipulation of information. In
the latter half of the 20th century, electrical engineering itself separated into several disciplines,
specialising in the design and analysis of systems that manipulate physical signals; electronic
engineering and computer engineering as examples; while design engineering developed to deal
with functional design of man–machine interfaces.
Definitions specific to sub-fields are common. For example, in information theory, a signal is a
codified message, that is, the sequence of states in a communication channel that encodes a
message.
In the context of signal processing, arbitrary binary data streams are not considered as signals,
but only analog and digital signals that are representations of analog physical quantities.
In a communication system, a transmitter encodes a message to a signal, which is carried to a
receiver by the communications channel. For example, the words \"Mary had a little lamb\"
might be the message spoken into a telephone. The telephone transmitter converts th.
Why do IDPs & IDRs lack structure Lack a ligand or partner Denatu.pdf
Why do IDPs & IDRs lack structure? Lack a ligand or partner? Denatured during isolation?
Folding requires conditions found inside cells? Lack of folding encoded by amino acid
sequence?
Solution
IDPs (Intrinsically disordered protein) and IDRs (Intrinsically disordered regions) lack structure
due to lack of folding encoded by amino acid seuence. In general, IDPs are characterized by a
low content of bulky hydrophobic amino acids and a high proportion of polar and charged amino
acids, usually referred to as low hydrophobicity. This property leads to good interactions with
water. Furthermore, high net charges promote disorder because of electrostatic repulsion
resulting from equally charged residues. Thus disordered sequences cannot sufficiently bury a
hydrophobic core to fold into stable globular proteins. Some proteins are fully disordered while
some are partial. Partial disordered proteins have some disordered regions (IDRs). Hence, IDPs
and IDRs have no fix structure and cover a spectrum of states from fully unstructured to partially
structured and include random coils, (pre-)molten globules, and large multi-domain proteins
connected by flexible linkers..

Why is methyl salicylate not appreciably soluble in waterSoluti.pdf
Why is methyl salicylate not appreciably soluble in water?
Solution
Methyl salicylate is not soluble in water due to the presence of benzene ring which is
hydrophobic in nature leading to dispersion forces between the ester molecules. Secondly, the
presence of OH group gives rise to hydrogen bonding with the water molecules. This hydrogen
bonding is weak in nature since the dispersion forces between the two benzene rings are more
leading to decreased solubility of methyl salicylate in water..
Who are stakeholders Define who they are and then please share what.pdf
Who are stakeholders? Define who they are and then please share what particular interest each of
these stakeholders have in the information shared on the income statement, retained earnings
statement, balance sheet and statement of cash flows. How do we analyze if a company is
healthy or not?
Solution
Stakeholders are those persons or group of persons who have a interest in the company. The
Interest that they have may be financial or non financial, such as an employee has a financial
interest but customers have non-financial interest. Stakeholders are concerned about the working
of a company. Stakeholders are of two types
Various Types of Stakeholders are as follows:-
Different stakeholders have different interests in the company. Various Stakeholders and their
Interests are given below.
1.Customers. Customers have a stake in the goods of the company. Customers need to know that
company is making progress; it increases their confidence in using company’s products. All a
Customer need is Good a quality product with future care. A customer can understand from
Income statements of a company that whether companies do any research expenses to make their
product better for consumption.
2. Employees. Employees wants to see what company pays to them as a compensation for their
hard work. Companies Value added statements show the percentage of revenue distributed to
employees of company. Employees are also concerned about their job security. A profit making
company is suppose to give a satisfaction to employee that he has a good future in company.
3.Government. Government Collects takes which can be ascertained by reviewing Income
statement. Moreover companies help government by providing employment to millions of
people. Government has interest in knowing that companies prepare their financial statements
truthfully and frauds like Enron are not done.
4. Stock Holders. Stock Holders are basically owners of a company, They take major decisions
in working of a company. Results shown by income statements, Balance sheets and cash Flow
Statements help them take future decisions with precision.
5. Society. Society is also concerned about the working of business organizations. They have a
stake in Corporate Social Responsibility policies of a company. Whether company is taking
necessary steps to minimize pollution of water, air, or total environment as a whole. The
employment rate is another example of society’s stake in businesses.
6. Suppliers. Suppliers are Concerned about that cash position of company. The Current ratio of
Company. They supply Inventory so they need to know whether company is able to pay their
dues in time. Cash Flow statements show a supplier the position of cash of a company.
7. Creditors. Creditors are concerned about the payment of their dues.
8. Lenders. Lenders such as Bond Holders or Preference stock holders are concerned about the
efficient of use of their money and the return on their money. No one wants to lend his money to
a c.

What is UWIN and what does it doSolutionUWin is a software .pdf
What is U/WIN and what does it do?
Solution
U/Win is a software package. It is used to run Unix applications in windows.
For eample if u have some programs which were written for the UNIX environment, you can use
U/WIN to run those programs in windows systems by making few or no changes.
U/WIN contains libraries that emulate UNIX environment by implementing the UNIX API.
Most of the Unix API is implemented by the POSIX.DLL dynamically loaded library (DLL).
Programs linked with POSIX.DLL run under the Win32 subsystem instead of the POSIX
subsystem.
so programs can freely intermix Unix and Win32 library calls..

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

The Roman Empire A Historical Colossus.pdf
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

- 6. similarly, instead of: char address[500]; change it to: vector address(500); and finally change addressbook book[10]; to: vector book(10); You might have figured it out by the changes but for reference, changing an array to vector has to be done by mentioning "vector" followed by the "data_type" inside "<>" and then mentioning the name of the identifier(variable) like in an array and providing its size, but the size has to be inside "()" instead of "[]". Edit1- include the vector header file at the header section as: #include Here is the complete code- # include # include # include #include using namespace std; class addressbook { private: vector name(500); long ph_num; //class addressType :public addressbook vector address(500); int year; int mounth; int day; char gender; int d, Th, y; char M, F, m, f; // char freind[]; public: addressbook(); void setName();
