1. English Composition.Week 7 DiscussionFor the discussion board you are required to post one primary post by Wednesday and reply to two classmates by Saturday. The posts must be made on (3) separate days to ensure your participate at least 3 days. Remember you need to add substantively to the conversation. The discussion board is only for the topic being discussed. We have a class cafe where you can meet other students and ask them questions and we have an “ask the professor” area that you can use to ask me questions.Step 1 Post a response to the discussion board.Respond to the following questions and, if it's relevant, include your own personal experience:What is the difference between editing and revising?What are examples of editing and why is editing important?What are examples of revision and why is revision important?Step 2 Read and respond to other students' posts.Read other students' posts and respond to at least two of them. In addition to other comments you may have, address the following in your response posts:What did you learn from the author's observations? Can you offer additional advice or insight?Use your personal experience, if it's relevant, to support or debate at least two other students' posts. If differences of opinion occur, debate the issues professionally and provide examples to support opinions.2. Psychology.2.1 Media InfluenceObjectiveDescribe aggression and prosocial behaviorAssignment OverviewThis reaction and response exercise explores the effect of the media on aggression. Be sure to cite each one at the end of the paper.DeliverablesA one-page paper (double spaced 12-point font)Step 1Find online articles about the influence of media on aggressive behaviors.Step 2Summarize the main points of the articles.In your one-page paper, include descriptions of any contributing factors you identified.Step 3Save and submit your assignment.After you complete the assignment, save a copy for yourself in an easily accessible place and submit a copy to your instructor using the dropbox.2.2 Discussion.For the seventh Discussion in our course, please answer the following:What are the major differences between the psychodynamic and learning approaches to personality?**Separate documents, no plagiarism, APA form, First point English composition and the last two psychology. Thanks**

Question 1 (6 points)Give an example of each of the following. You can answer this by drawing rough graphs and giving an explanation in one line in each case (3 points).y is function of x, but x is not a function of y.y is not a function of x but x is a function of y.y is a function of x and x is a function of y.In each of the following cases, determine the real roots (if any) (3 points) (i) 2x2 -4x + 6 =0 (ii) x2 -2x + 1 =0 (iii) 2x2 -5x + 2=0Question 2 (9 points)Consider an economy with two sectors - food and manufacturing. Each sector uses labour to produce its output, and labour is mobile across both sectors, so that in aggregate labour market equilibrium, workers earn the same wage in both sectors. The supply of labour in the economy is exogenously given. In addition, food requires land and manufacturing requires capital. These factors are not mobile at all, and their quantities are exogenously given. This model can be expressed in terms of the following equations.1. Lf = a - bw + eT0 a > 0, b > 0, e > 0 2. Lm = c - dw + gK0 c > 0, d > 0, g > 0Lf +Lm = L0Equation (1) describes the demand for labour in food production (Lf), where w is the wage and T is the supply of land. Similarly, equation (2) depicts the demand for labour in manufacturing production (Lm), with K standing for the supply of capital. Equation (3) is the equilibrium condition for the economy's labour market: the total demand for labour should equal the exogenously given supply of labour (L0)Solve for the equilibrium wage using the equilibrium condition. (3 points)Determine the impact of an increase in the stock of capital by 2 units on the equilibrium wage. (2 points) Then find the impact on the equilibrium wage of an increase in the stock of land by 2 units. (2 points) Would the equilibrium wage increase, decrease, or remain unchanged if the quantity of capital increased by 2 units and, simultaneously, the quantity of land decreased by 2 units. Explain your answer.(2 points)Question 3 (7 points)Simplify each of the following expressions. (2 points)(i) (x0.5 + x3/4x-1/4)/x0.25) (ii) x-2x3/2/x1/3 (iii) (x1/4y-2)-3 (iv) (64x9)1/3 (16y)-2Consider the consumer demand function for blueberries: Q = P-aRb Xc where a, b and c are positive constants, Q = quantity of blueberries demanded, P =price of blueberries, R= price of raspberries, and X= consumer income.Suppose the initial values of P, R and X are P0, R0 and X0. Now both P and R rise by 20 percent(X remaining unchanged). Show how demand Q would change as a result? Specifically, would demand rise by more than 20 percent, less than 20 percent, or by 20 percent? Show your work. (3 points)Economic theory tells us that if P, R and X all rise simultaneously by the same percentage, demand Q would not change? In the demand function given above, what condition would ensure this? Explain. (2 points)Question 4 (8 points)Find the natural logs of each of the following economic relationships:α βProduction function in time period t: : Qt = Kt Lt , where K and L are factors of production such thatKt = K0eut, Lt = L0evt, Q is output, and α, β, u, v, L0, and K0 are all constants. (3 points)Revenue function: R= PQ, where P=aQ-b is the demand curve for the product, andQ = [hKu + (1-h)Lu] r/u, where a, b, r and u are constants. (3 points)Present value: V = y/(1+i)n , where V is the present value of a sum of money y to be received n years ahead, and i is the rate of interest. (2points)
