A:782million dolarB:868million dolarC:910million dolarD:876million dolar QI (20 points): A contractor prepared for the bidding of an international construction project estimates that the total cost of the project will be A Million Dollars. For the contract between the Owner and the Contractor, there are three options given below: • Option 1: A lump-sum contract with a 10% profit over the estimated project cost. • Option 2: A cost plus fixed fee contract with a fixed fee of 30 Million Dollars and the Guaranteed Maximum Price (GMP) of B Million Dollars. • Option 3: A cost plus percentage fee contract with a 5% percentage fee and the Guaranteed Maximum Price (GMP) of C Million Dollars. If the actual cost at the end of the project is given as D Million Dollars, calculate the net profit loss of the Contractor for three contract options and select the best contract option for the Contractor Note: A, B, C, and D numbers are given in the attached Excel sheet (Question 1). You should write your student ID into the B2 cell to get these numbers. G HD 6

For the following exercises, find the surface area of the volume generated when the following curves revolve around the y-axis. If you cannot evaluate the integral exactly, use your calculator to approximate it. 199. y = x2 from x = 0 to x = 2

For the following exercises, find the lengths of the functions of y over the given interval. If you cannot evaluate the integral exactly, use technology to approximate it. 181. y = 5 - 3x from y = 0 to y = 4 – 4

For this week's discussion, you are asked to generate a continuous and differentiable function f (2) with the following properties: • f(x) is decreasing at x = -6 • f(x) has a local minimum at x = -3 • f (x) has a local maximum at x = 3 Hints: • Use calculus! • Before specifying a function f (2), first determine requirements for its derivative f' (2). For example, one of the requirements is that f' (-3) = 0. • If you want to find a function g(x) such that g(-9) = 0 and g(8) = 0, then you could try g(x) = (x + 9) (x – 8). • If you have a possible function for f' (2), then use the techniques in Indefinite Integrals this Module to try a possible f (x). You can generate a plot of your function by clicking the plotting option (the page option with a "P" next to your function input). You may want to do this before clicking "How Did I Do?". Notice that the label "f(2) =" is already provided for you. Once you are ready to check your function, click "How Did I Do?" below (unlimited attempts). Please note that the bounds on the x-axis go from -6 to 6. f(x) = How Did I Do? Try Another
