How many years does it take an investment to triple in value if i.pdf
How many years does it take an investment to triple in value if it is invested at 7.5%
compounded monthly? Round your answer to 2 decimal places.
Solution
Future value of investment = initial investment * (1 + i/n)^(t*n)
where
i = interest per year = 7.5%
n = number of periods in a year = 12
t = number of years, amount is invested
let X be the initial investment
=>
future value = 2X
=>
X * (1+7.5%/12)^(t*12) = 2X
=>
(1.00625)^12t = 2
=>
12t = ln(2)/ln(1.00625)
=>
t = 9.27 years .........ans.
Home Depot Inc. (HD) had 1.70 billion shares of common stock outstand.pdf
Home Depot Inc. (HD) had 1.70 billion shares of common stock outstanding in 2008, whereas
Lowes Companies, Inc. (LOW) had 1.46 billion shares outstanding. Assuming Home Depot\'s
2008 interest expense is $696 million, Lowes\' interest expense is $239 million, and a 38 percent
tax rate for both firms, what is their break-even level of operating income (i.e.: the level of EBIT
where EPS is the same for both firms)? The EBIT indifference level is $ . (Round to the nearest
dollar.)
Solution
(EBIT - Intt)/10.70 = (EBIT - Intt)/14.60
(EBIT - 696)10.70 = (EBIT - 239)/14.60
10.70 EBIT - 7447.20 = 14.60 EBIT - 3489.4
EBIT = 1014.82 million.

How are satellites identified?
Solution
Generally Satelites are identified based on the orbit they are placed in. there are 4 kinds of
satelites they are
i)Low Earth orbits:Satelites which are placed in the low earth orbits mainly used for military
purposes. It will be placed above 160 Km from earths surface.
ii)Sun synchronous Satelites: These are placed in heliosynchronous orbits or polar orbits.These
satelites orientation is fixed to the orientation of the sun through out the year.
iii)Geo Stationary satelites:These satelites take 24 hrs to complete one rotation.These satelites
are mainly used for communication purposes.These are placed directly over the equator and their
path is the equitorial plane.These are placed at a height of about 35778 Km.

Here are key figures from the balance sheet of Rome, Inc., at the.pdf
Here are key figures from the balance sheet of Rome, Inc., at the end of 2014 (amounts in
thousands): Rome\'s debt ratio at the end of 2014 is (all amounts are rounded)
Solution
Debt ratio = total debt/total assets
total debt = current liabilities+long term debt
total assets = current assets+fixed assets+intangible assets
total debt = 600 (current liabilities) +1400 (bonds payable) = 2,000
total assets = 7,000
debt ratio = 2,000/7,000 = 28.57% or 29%.
How are the different dimensions of globalization - economic, polit.pdf
Globalization refers to the integration of countries across economic, political, cultural and ecological dimensions. Economically, globalization involves the integration of world economies through increased international trade and the spread of multinational corporations. This economic integration is accompanied by increasing social and political integration, as Western culture and values spread worldwide. International institutions also influence countries' political systems. Rising international trade and its environmental externalities, like pollution and greenhouse gases, demonstrate how ecological impacts have also been globalized.
Hi, Id like some help on modeling a prediction equation in R. Her.pdf
Hi, I\'d like some help on modeling a prediction equation in R. Here\'s the relevant information:
Table 4.13 shows the result of cross classifying a sample of people from the MBTI Step II

How does RFID work and differentiate with bar coding. Also what is the impact of RFID in
B2B e-Commerce. Discuss Collaborative Commerce and its benefits
Solution
RFID stands for radio frequency identification tag associated with each products. The main
difference between the working of RFID and Barcoding are as follows:
RFID Working: In RFID method a tag is affixed to the products which is used to identify and
track product via radio waves. These tags can store or carry upto 2,000 bytes of data. RFID
technology has three parts namely the scanning antenna, a transceiver and a transponder. The
transceiver comes with a decoder to interpret the data and the transponder comes with the pre-set
with information.The scanning antenna is used to send a radio-frequency signal to the RFID
tag. As the RFID tag is passed through the frequency field of the scanning antenna; it will be
able to detect the activation signal and further will be able to transfer the information data it
holds to be picked up by the scanning antenna.
Bar Coding: A visual representation of data that is scanned and interpreted for information is
called as barcodes. A certain code is present in each barcode which works as a tracking
technology for products. It is usually represented as a sequence of lines or in other shapes.
Barcodes initially were one dimensional and were based on the width and spaces between
parallel lines but later they were developed as two-dimensional with many geometrical shapes
used for bar-coding. The barcode technology can be scanned with the help of bar-code readers.
Impact of RFID in B2B and E-Commerce are as follows: RFID has a great impact on the B2B
and E-commerce business since the radio frequency codes can now be checked easily. RFID has
playeda significant role in fostering a higher level of integration between the supply chain
members.
Collaborative Commerce: C-Commerce or Collaborative commerce is a new business strategy
that looks at the supply chain managment in a difference way. It describes about the selection
and project based cooperation between one or more parties or parteners along the supply chain.
Collaborative commerce is further seen as a tool that combines knowledge management, supply
chain management and e-commerce.
Benefits of Collaborative Commerce are as follows:
1. Cost Advantages.
2. Concentration on core competencies
3. Innovations are encouraged
4. Reduction in inventory
5. Reduced time-to-market.
How do you calculate the stock price for both scenarios He asked .pdf
How do you calculate the stock price for both scenarios? He asked Ms. Firewater to prepare a
formal report to Prairie Home stockholders, valuing the company on the assumption that its
shares were publicly traded. Ms. Firewater asked two questions immediately. First, what should
she assume about investment and growth? Mr. Breezeway suggested two valuations, one
assuming more rapid expansion (as in the top panel of Table 3.8) and another just projecting past
growth (as in the bottom panel of Table 3.8). Second, what rate of return should she use? Mr.
Breezeway said that 15 percent, Prairie Home?s usual return on book equity, sounded right to
him, but he referred her to an article in the Journal of Finance indicating that investors in rural
supermarket chains, with risks similar to Prairie Home Stores, expected to earn about 11 percent
on average. Rapid-Growth Scenario 1 2 3

4.9 5.1 Book value, end of year 84 88.2 92.6 97.2 102.1 107.2
Notes: 1. Both panels assume earnings equal to 15 percent of start-of-year
book value. This profitability rate is constant. 2. The top panel assumes all earnings are
reinvested from 2005 to 2009. In 2010 and later years, two-thirds of earnings are paid out as
dividends and one-third reinvested. 3. The bottom panel assumes two-thirds of earnings are paid
out as dividends in all years. 4. Columns may not add up because of rounding.
Solution
Valuation based on constant growth scenario
Growth Rate = Return on Equity x Plowback ratio = 15% x 1/3 = 5%
Value of the equity =DIVx(1+g)/ (r-g) =$10.2 million x (1+0.05)/(15%- 5%) =$10.71 million/
10%
= 107.10 million
Value per share = Value of the equity / No. of shares Common Shares Outstanding =
= $107.10 million /400,000
= $267.75 per share
Valuation based on rapid growth scenario
Plowback ratio is 1 as the entire income is reinvested for the next five years.
Value of equity = DIV 2010 x (1+g) / r-g (Assume same as in constant growth scenario)
= $14.7 million x (1+.05) / (15%- 5% )
= 154.35 milion
Value per share = $154.35 / 400,000
= $385.875
Rapid growth scenario is preferable as the value of per share is greater in rapid growth scenario..

if f and g are surjective, then f o g is surjective.SolutionL.pdf
if f and g are surjective, then f o g is surjective.
Solution
Let me explain in a bit more detail :
Let fog : A -> C
fog is onto if, for every c in C, there exists as a in A such that fog(a) = c.
But since f is onto, we have that f(b) = c for some b in B, and
since g is onto, we have that b = g(x) for some x in A (I changed the letters to avoid confusion).
So g(x) = b
f(g(x)) = f(b) = c
So this value of x exists, which is what we wanted to show.
I hope this helps!.

Identify elements associated with the preparation of a programmable l.pdf
Identify elements associated with the preparation of a programmable logic controller program.
Before starting the development of a programmable logic controller program, there are a number
of important steps which shall be taken into consideration e.g. selection of PLC based on
input/output, etc...identify some other important steps and elements.
Solution
A programmable logic controller, PLC, or programmable controller is a digital computer used
for automation of typically industrialelectromechanical processes, such as control of machinery
on factory assembly lines, amusement rides, or light fixtures. PLCs are used in many machines,
in many industries. PLCs are designed for multiple arrangements of digital and analog inputs and
outputs, extended temperature ranges, immunity to electrical noise, and resistance to vibration
and impact. Programs to control machine operation are typically stored in battery-backed-up or
non-volatile memory. A PLC is an example of a \"hard\" real-time system since output results
must be produced in response to input conditions within a limited time, otherwise unintended
operation will result.
Before the PLC, control, sequencing, and safety interlock logic for manufacturing automobiles
was mainly composed of relays, cam timers,drum sequencers, and dedicated closed-loop
controllers. Since these could number in the hundreds or even thousands, the process for
updating such facilities for the yearly model change-over was very time consuming and
expensive, as electricians needed to individually rewire the relays to change their operational
characteristics.
Digital computers, being general-purpose programmable devices, were soon applied to control of
industrial processes. Early computers required specialist programmers, and stringent operating
environmental control for temperature, cleanliness, and power quality. Using a general-purpose
computer for process control required protecting the computer from the plant floor conditions.
An industrial control computer would have several attributes: it would tolerate the shop-floor
environment, it would support discrete (bit-form) input and output in an easily extensible
manner, it would not require years of training to use, and it would permit its operation to be
monitored. The response time of any computer system must be fast enough to be useful for
control; the required speed varying according to the nature of the process.[1] Since many
industrial processes have timescales easily addressed by millisecond response times, modern
(fast, small, reliable) electronics greatly facilitate building reliable controllers, especially because
performance can be traded off for reliability.
In 1968 GM Hydra-Matic (the automatic transmission division of General Motors) issued a
request for proposals for an electronic replacement for hard-wired relay systems based on a white
paper written by engineer Edward R. Clark. The winning proposal came from Bedford
Associates of Bedford, Massachusetts. T.

if f and g are surjective, then f o g is surjective.SolutionL.pdf
if f and g are surjective, then f o g is surjective.
Solution
Let me explain in a bit more detail :
Let fog : A -> C
fog is onto if, for every c in C, there exists as a in A such that fog(a) = c.
But since f is onto, we have that f(b) = c for some b in B, and
since g is onto, we have that b = g(x) for some x in A (I changed the letters to avoid confusion).
So g(x) = b
f(g(x)) = f(b) = c
So this value of x exists, which is what we wanted to show.
I hope this helps!.

the second group has more variation, but only SLIGHTLY.. the first group has a
standard deviation of 14.538, where as the second group has a standard deviation of 14.782,
therefore making it have more variability. the standard deviation is the best to use because it is
not affected by outliers. the second group has also a more skewed distribution than the first
group..

Identify elements associated with the preparation of a programmable l.pdf
Identify elements associated with the preparation of a programmable logic controller program.
Before starting the development of a programmable logic controller program, there are a number
of important steps which shall be taken into consideration e.g. selection of PLC based on
input/output, etc...identify some other important steps and elements.
Solution
A programmable logic controller, PLC, or programmable controller is a digital computer used
for automation of typically industrialelectromechanical processes, such as control of machinery
on factory assembly lines, amusement rides, or light fixtures. PLCs are used in many machines,
in many industries. PLCs are designed for multiple arrangements of digital and analog inputs and
outputs, extended temperature ranges, immunity to electrical noise, and resistance to vibration
and impact. Programs to control machine operation are typically stored in battery-backed-up or
non-volatile memory. A PLC is an example of a \"hard\" real-time system since output results
must be produced in response to input conditions within a limited time, otherwise unintended
operation will result.
Before the PLC, control, sequencing, and safety interlock logic for manufacturing automobiles
was mainly composed of relays, cam timers,drum sequencers, and dedicated closed-loop
controllers. Since these could number in the hundreds or even thousands, the process for
updating such facilities for the yearly model change-over was very time consuming and
expensive, as electricians needed to individually rewire the relays to change their operational
characteristics.
Digital computers, being general-purpose programmable devices, were soon applied to control of
industrial processes. Early computers required specialist programmers, and stringent operating
environmental control for temperature, cleanliness, and power quality. Using a general-purpose
computer for process control required protecting the computer from the plant floor conditions.
An industrial control computer would have several attributes: it would tolerate the shop-floor
environment, it would support discrete (bit-form) input and output in an easily extensible
manner, it would not require years of training to use, and it would permit its operation to be
monitored. The response time of any computer system must be fast enough to be useful for
control; the required speed varying according to the nature of the process.[1] Since many
industrial processes have timescales easily addressed by millisecond response times, modern
(fast, small, reliable) electronics greatly facilitate building reliable controllers, especially because
performance can be traded off for reliability.
In 1968 GM Hydra-Matic (the automatic transmission division of General Motors) issued a
request for proposals for an electronic replacement for hard-wired relay systems based on a white
paper written by engineer Edward R. Clark. The winning proposal came from Bedford
Associates of Bedford, Massachusetts. T.
