Question 5. Set up, but do not evaluate, a single integral to find the volume of the solid generated by revolving the region bounded on the left by x = y2 +3 and on the right by x = 6 - y2 around the line x=-1.

The Laplace Transform, named after "the Newton of France" Pierre-Simon Laplace, is an integral transformation used in many fields of engineering. Let F(t) be a function of t > 0 The Laplace Transform of F is a new function in the variable s: L(F) = f(3) = | = = =1 e-st F(t) dt. 0 For example -st at = 1 e 0 • L(1) = | * - • f(t) = 1 - 1 C(sin(t) = | j e st Stt dt = 0 . e -st sin(t) dt = 0 One of the many uses of the Laplace Transform is to evaluate integrals. By choosing one of the Laplace Transforms above, and a suitable value of s, we can evaluate oo - 4t 1 e dt = 4 - - . 0 oo - 3ttat e = 0 -3t e sin(t) dt 0

Question Suppose three point masses are placed in the xy-plane as follows (assume coordinates are given in meters): mi = 5 kg, placed at (-2, -3) m2 = 3 kg, placed at (2,3) 'm3 = 2 kg, placed at (-3, -2) Find the center of mass of the system. Write your answer as an ordered pair Provide your answer below:

let f(x)= x^2-5, g(x)= 2x^3+x and p(x)= f(x)g(x). a) computedp/dx b) compute f'(x)g'(x)

10. A box is lying on top of a trailer, which is parked on the road. According to Newton's third law, what is the reaction force to the gravitational pull of the box on the trailer? The normal force of the trailer on the box The gravitational pull of the trailer on the box The gravitational pull of the trailer on Earth The normal force of the road on the trailer The weight of the trailer The normal force of the trailer on the road The gravitational pull of the box on Earth The weight of the box

Suppose that a company is developing a new touch-screen cell phone. Historically, 70% of their new phones have resulted in high consumer demand, whereas 30% have resulted in low consumer demand. The company has the decision of choosing between two models with different features that require different amount of investment and have different sales potential. Estimated profit/loss are shown in the payoff table below. State of Nature High demand, ($) Low demand, ($) Model 1 300,000 -40,000 Model 2 275,000 -15000 Now suppose the firm conducts a market research study to obtain sample information and better understand the nature of consumer demand. The market research cost $10,000 Analysis of past market research studies, conducted prior to introducing similar products, has found that the survey response will be either high or low. There is a 69% chance that the survey will return a high survey response (results) and there is a 31% chance that the survey will result in lo-demand response (results). The relevant conditional probabilities are as follows: P (high consumer demand, high survey response = 0.913) P (low consumer demand, low survey response = 0.087) P (high consumer demand, high survey response = 0.226) P (low consumer demand, low survey response = 0.774) Calculate the expected value of sample information (EVSI).
