B. ]Write the equation of the tangent line to the curve at the point (3, 1}. C. At (3, 1), x) is defined implicitly as a function of x. Let 9(1) be the inverse function of yix). Compute 911 j. 12. A race car is running practice laps in preparation for an upcoming race. Tojudge how the car is performing, the crew takes measurements of the car's speed Sit} (in miles per hour. or mph} every minute. The measurements are given in the table below. i (minutes) 3U) (mph) 2l 205 203 2 [4 2 [R 2 l2 2 [9 223 22!] 9 22| ll] 2 l? l I 2 [3 l2 2 if: NH 3'45\"th A. Use the trapezoid mle with 4 equal subdivisions to approximate the total distance the car traveled (in miles) over the first 12 minutes. E. Find one approximation for 515), including the units. Explain what this quantity means in the context of the problem. C. What was the car's average speed in mph over the first [2 minutes? If the car needs to have an average speed of 2|!) mp1: to qualify for the race, is it currently running fast enough to qualify? 13. Let M be the region under the graph of x) = 99'. from x = D to x = 5. A. Find the area of M. B. Find a value of c so that the line 1 = c divides the region M into two pieces with equal area. 0. M is the base of a solid whose cross sections are semicircles whose diameter lies in the xy plane. The cross sections are perpendicular to the xaxis. Find the volume of this solid. You may NOT use your calculator on the following three questions. 14. Let g be a function whose domain is The closed interval [0, B]. The graph of g is shown above. The graph is made up of straight line segments and a semicircle. 21-1 Let x} = j gm d1. A. Computeg} B. ]What is the domain of 1"? C. Find f'i3}. D. Find the xcoerdinate of the absolute maximum of fon its domain. 15. Water is draining from a small cylindrical tank into a larger one below it. The small cylindrical tank has a radius of 4 feet and a height of 6 feet; the large cylindrical tank has a radius of 8 feet and a height of 16 feet. The small tank is initially full of water, and the water drains out at a rate of + cubic feet per second. Note: The volume of a cylinder is V = TI/h. A. Find the volume Vs of the water remaining in the small tank as a function of time. B. How long does it take for the small tank to completely empty? C. Let z be the depth of the water in the large tank, which is initially empty. Compute #. D. What fraction of the total amount of water is in the large tank at time t = 6? 16. Suppose that f has a continuous second derivative for all x, and that f(0) = 1, f'(0) = 2, and f"(0) = 0. A. Does f have an inflection point at x = 0? Explain your answer. B.
