In Silicon Valley, a number of computer firms were found to be contaminating underground water supplies with toxic chemicals stored in leaking underground containers. A water quality control agency ordered the companies to take immediate corrective action and contribute to a monetary pool for the testing and cleanup of the underground contamination. Suppose that the required monetary pool (in millions of dollars) is given by the following function, where x is the percentage (expressed as a decimal fraction) of the total contaminant removed. Complete parts (A) through (E). 2x P(x ) = 1-X OSX co In x Select the correct choice below and, if necessary, fill in the answer box to complete your choice. X lim O A. x-+co In x (Simplify your answer.) O B. The limit does not exist.A company manufactures a variety of camp stoves at different locations. The total cost C(x) (in dollars) of producing x camp stoves per week at plant A is shown in the figure. Discuss the graph of the marginal cost C(x) function C'(x) and interpret the graph of C'(x) in terms of the efficiency of the production process at this plant. $100,000 $50,000 x 500 1,000 Choose the correct answer below. O A. The graph of y = C'(x) shows that the marginal cost function is positive and decreasing. Since marginal costs are decreasing, the production process is becoming more efficient as production increases. O B. The graph of y = C'(x) shows that the marginal cost function is positive and increasing. Since marginal costs are increasing, the production process is becoming less efficient as production increases. O C. The graph of y = C'(x) shows that the marginal cost function is negative and increasing. Since marginal costs are increasing, the production process is becoming less efficient as production increases. O D. The graph of y = C'(x) shows that the marginal cost function is negative and decreasing. Since marginal costs are decreasing, the production process is becoming more efficient as production increases
