I need help with this one. Use the function to evaluate the indicated expressions and simplify. f(x) = 2x^2 + 5 f(x + 2) = f(x) + f(2) = Solution Given f(x)=2x^2 + 5 To find out f(x+2) so, f(x+2) = 2(x+2)^2 + 5 = 2(x^2+4x+4) + 5 =4x^2 + 8x + 8 + 5 = 4x^2 + 8x +13 Again to find out f(x) + f(2) => f(x) + f(2) = 2x^2 + 5 + (2(2)^2 + 5) = 2x^2 + 5 +13 = 2x^2 +18.

3. Photosynthetic organisms produce about 300 x 1015 g of oxygen per year (Holland 1995. If this oxygen accumulated, the oxygen content of the atmosphere would double every 2000 years. Why does this not happen? Is the global system regulated? If so, how is this regulation accomplished? Solution Oxygen is considered as one of the most important gas in the atmosphere .it would have been impossible to imagine life without this gas. The contribution of oxygen to the atmosphere is mainly due to the photosynthetic activity of the plants apart from this the splitting of the hydrogen atoms from water vapor in the atmosphere due to photolysis also contributes to oxygen of the atmosphere to a negligible amount.the oxygen is left behind and the hydrogen escapes. The major contributor of atmospheric oxygen is the photosynthetic activity of the plants but this does not accumulate in the atmosphere as most of it is immediately used up by the respiration process. the maintenance of oxygen levels is one of the classic example of homeostasis . Of the amount of oxygen produced though all of it is immediately used in the respiratory process The net gain of oxygen comes from the burial of organic matter (plant and animal matter ) which reacts with the reducing substances of the earth like iron and is locked as the solid oxides over time. Eventually it would be all used up and equilibrium atmosphere would not contain more oxygen. The continuous photosynthesis and carbon burial keeps the level of oxygen as high as it is and thus homeostasis is maintained ,Where plant photosynthesis acts as the the pump and the rate of burial is equivqlent of the aperture between the reservoir halves..

1. Which is less soluble in water, 1-pentanol or 1-heptanol? Explain. 2. Write an equation for the reaction of methanol with sodium 3. Write an equation for the reaction of 2-butanol with the Lucas reagent. 4. Describe the odor of the product derived from mixing isopentyl alcohol and acetic acid, and write the equation for its formation Solution 1) 1-heptanol is lest soluble in water. Because solubility depend upon the type of bond present in the molecule.1- heptanol has loneger non polar chain as compare to 1- heptanol. Hence its hydrophobic part make it less soluble in water.Therefore from above conclusion we an say that 1- heptanol is less soluble in water as comare to 1- pentanol..

Why did animal phyla appear so suddenly during the Cambrian explosion? Several variables have been hypothesized to play a role in the sudden appearance of diverse animals during the Cambrian explosion. For example, the \'higher oxygen levels\" hypothesis invokes an environmental trigger and the \"evolution of predation\" hypothesis invokes ecological interactions. Erik Sperling, Andrew Knoll, and colleagues set out to test the hypothesis that these two hypotheses are linked. Could the oxygen atmosphere enable the evolution of predation? Sponges lived in low-oxygen oceans before the Cambrian, and they occur today in both low- oxygen and high-oxygen environments. What aspects of the sponge body plan might have prevented the evolution of predatory sponges in high-oxygen environments? Drag the terms on the left to the appropriate blanks on the right to complete the sentences. Effective predators tend to be and they have for detecting prey. Sponges lack, , and as adults.

Which of the following information-management systems uses artificial intelligence? A. Polyinstantiation B. Known signature scanning C. Application programming interface D. Knowledge discovery in databases Solution D. Knowledge Discovery in Databases (KDD) is an artificial intelligence method used to identify useful patterns in data; as such, it provides a type of automatic analysis. Answer A is incorrect because polyinstantiation is a technique used to prevent inference violations. Answer B is incorrect because known signature scanning is a method used to detect computer viruses. Answer C is incorrect because the application programming interface (API) is in no way associated with artificial intelligence.

This project will implement a simple username/password lookup system using hash tables. You should create the Hash Table from scratch. It may be helpful to create a separate class called HashEntry, in which you can store a String username and String password. The Hash Table will store these entries using the username as the key and the password as the value. Create a hash code using the key to determine where the value is stored in the Hash Table. Here is a sample hash method. Feel free to borrow it for your program: privateint calcHashCode(String key) { int mod = key.hashCode() % size; return mod < 0 ? mod + size : mod; } You will be provided with a data file containing comma separated usernames and passwords. Read the data in from the file and put it into the table. Once the table is populated, ask the user to log into the system. If their username and password match the data in the table, alert the user that access has been granted: Login: trevor User trevor not found.

Use whatever info or sources you can find to make the most socieconomically conscious argument for your position and present it to the rest of the taskforce Solution Yes. Money spent on education and educational research is never wasted. Government subsidizes universities with the hope of generating economic growth. It is only because of these subsidies that the prospective researchers and budding educationalists are motivated to go into research and create something new. In the absence of these subsidies, many students and researchers are demotivated because they are unable to arrange for required funds for their research. As a result of this many researchers leave their research in between, which is a big harm to the economy. The government should never doubt money it has spent on education and research because even if 1 out of 10 students are able to create something striking, its benefits will help reap the efforts and money invested in no time..

She didn t give her a whole lot of guidance about how to get the project done even though there s a decent risk of failure. This is Julie s typical way of managing her employees, and her employees respond very well to it. In fact, Mina is pretty pumped about this opportunity! Julie and Mina are most likely from what type of culture? 0 High power distance High individualism High long-term orientation Low power distance Low uncertainty avoidance Solution 10) High Individualism Individualism is categorised as the opposite of collectivism, i.e., high individualism means low collectivism. In individualism, people are expected to look after themselves and their closest family members. The integration into groups in workplaces are low and are expected to work by themselves and find results. 9) They are viewed primarily as female, not as foreigners or organizational members, leading to greater prejudice in the host country. This actually depends on the country in which they are serConsideringiderig the Hofstede cultural dimensions, different country have different notion towards females, however, most of the countries have a higher rate of gender discrimination than in North Amerca. This suggests towards the higher prejudice faced by the north American women serving as expatriates..

readings provide insight into the impact of technology on global business. Technological innovations such as the Internet, wireless technology, broadband, tablets, personal digital assistants (PDAs), global positional systems (GPSs), social media, videoconferencing, and others have changed the way we do global business. Then, respond to the following: Describe how changes in technology contributed to the globalization of markets. Explain how the Internet affects international business activity and the globalization of the world economy. Write your initial response in 300–500 words. Solution Technology enhances globalization. In past two decades, technology burst out like an explosion, definitely, the improvements of technology make our lives much more convenience. And, the advanced technology in microprocessors, Internet, and transportation enable the spreading out of globalization. Hill, C., (2001) stated \"Globalization has two main components: the globalization of markets and the globalization of product.\" In other words, the changing in technology would lead to an influence on globalization of markets and globalization of production. The Internet and the associated World Wide Web affects international business and the globalization of the world economy because they have made it easier for firms, large and small, to conduct international business. The Internet and the web have also made it possible for some firms to join the world economy. Before these advancements in technology, many small firms would not be able to conduct business outside of their domestic economy. And if they were, for whatever the reason may be, it would not have been with the ease and low costs that are associated with it today. This allows for globalization of the world economy because firms are able to join in to provide goods andservices that are in demand all around the world. Countries are able to outsource to other countries so that they can lower costs and improve the quality of their products. With globalization of the world economy, countries work together by intertwining their resources to create goods and services in order to better the world as a whole. Benefits of business activity are reaped by multiple countries versus one.

Program 1: (Practicing an example of function using call by reference) Write a program that reads a set of information related to students in C++ class and prints them in a table format. The information is stored in a file called data.txt. Each row of the file contains student number, grade for assignment 1, grade for assignment 2, grade for assignment 3, and grade for assignment 4. Your main program should read each row, pass the grades for the three assignments to a function called ProcessRow to calculate the average of the grades, minimum of the four assignments, and the maximum of the four assignments. The results (average, maximum, and minimum) should be returned to the main program and the main program prints them on the screen in a table format. For example, if the file includes 126534 7 8 10 7 321345 5 6 4 9 324341 8 3 8 5 your program should print Std-Id A1 A2 A3 A4 Min Max Average ---------------------------------------------------------------------------------- 126534 7 8 10 7 7 10 8 321345 5 6 4 9 4 9 6 324341 8 3 8 5 3 8 6 You must use call by reference to do the above question. _________________________________________________________________ Program 2: (Practicing an example of function using call by value) Repeat the above question using call by value. This means you need to have three different functions: one to calculate the average, another to calculate the minimum, and the third one to calculate the maximum. This is how to call these functions: Max = CalculateMax(A1,A2,A3, A4); Min = CalculateMin(A1,A2,A3, A4); Average = CalculateAvg(A1,A2,A3, A4); _________________________________________________________________ Program 3: Write a program with several functions that performs the following tasks. : Create a function that reads the following 5 float numbers from the file data.txt into array Called Arr1. 12.0 15.0 29.3 25.0 93.2 Copy array Arr1 into array Arr2 in reverse order Print array Arr1. Print array Arr2. Find the number of elements in array Arr1 that are >= 80 and <=100. Find the number of the elements in array Arr1 in which their contents are divisible by 5 Find the index of the elements in array Arr1 in which their contents are divisible by 3. Find mean (average) in array Arr1. Find the maximum number in array Arr1. Ask the user to input a key. Then search for the key in array Arr1 and inform the user about the existence (true / false) of the key in array Your program should include several functions. A function for filling up the information from file into an array (part a should call this function) A function that does the copying of one array into another in reverse order. Arrays must have the same size (part b should call this function) Printing any array with any size (part c and d should call this function) finding and returning the number of elements between 80 and 100 in any array with any size (part e calls this function) finding and returning the number of elements in an array that are divisible by 5 (par.

Linguist George Lakoff states that much of meaning in language is grounded in bodily metaphors (e.g., describing an attractive man or women as “hot”). Can you think of interesting examples of this? Solution Is it true that all of us, not just poets, speak in metaphors, whether we realize it or not? Is it perhaps even true that we live by metaphors? In Metaphors We Live By George Lakoff, a linguist, and Mark Johnson, a philosopher, suggest that metaphors not only make our thoughts more vivid and interesting but that they actually structure our perceptions and understanding. Thinking of marriage as a \"contract agreement,\" for example, leads to one set of expectations, while thinking of it as \"team play,\" \"a negotiated settlement,\" \"Russian roulette,\" \"an indissoluble merger,\" or \"a religious sacrament\" will carry different sets of expectations. When a government thinks of its enemies as \"turkeys or \"clowns\" it does not take them as serious threats, but if the are \"pawns\" in the hands of the communists, they are taken seriously indeed. Metaphors We Live By has led many readers to a new recognition of how profoundly metaphors not only shape our view of life in the present but set up the expectations that determine what life well be for us in the future. (from introduction in The Conscious Reader).
