Thursday, 12/3 F #70 (yes, it is strange that this 5 sheet is #70) As shown in the figure above, water is draining from a conical tank with height 12 feet and diameter 8 feet into a cylindrical tank that has a base with area 400π square feet. The depth h, in feet, of the water in the conical tank is changing at the rate of (h 12) feet per minute. The volume V of a cone with radius r and height h is V = 1 3 πr2 h. (a) Write an expression for the volume of water in the conical tank as a function of h. (b) At what rate is the volume of water in the conical tank changing when h = 3? Indicate units of measure. (c) Let y be the depth, in feet, of the water in the cylindrical tank. At what rate is y changing when h = 3? Indicate units of measure. Let f be a function whose domain is the closed interval [0, 5]. The graph of f is shown below. x Consider the function G defined by G(x) = f(t). 0 (a) Find G(3). (b) On what intervals is G increasing and concave down? Show your reasoning. (c) Find an equation of the tangent line to the graph G at the point where x = 3. I 1.

SURPRISE TESTS 1. AP-type exam, usually multiple choice questions because many questions are still unknown to you, a guessing equalizer applies...to keep you from guessing on what you don t know. (minus 1 1/4 for an incorrect answer) there is NO guessing penalty on the actual AP exam. 2. There will be more questions than you can answer in time allotted. There may be problems that we haven't covered yet. Work as quickly as you can doing the easiest problems first. 3. Sometimes with, sometimes without calculators 4. Will count like a normal test if you miss it, you will take the Comprehensive Make-up Exam 5. No homework the night of a Surprise Test. Thus, the 5 sheets are not dated near the time of a surprise test, to keep you surprised! F #66 Worksheet #21 Problems (17,18,19,36,39,43) Show work without a calculator.

V = 1 3 πr2 r h Since in the cone, h = 4 12 = 1 3, then V = 1 3 π 1 3 h 2 1 h = 27 π h3 dv = 1 dh π h2 substituting h = 3 and dh = h 12 yields 9 dv = 1 9 h2 (h 12) = 1 9 π (9) ( 9) = 9π ft3 /min Rate of decrease in conical tank = rate of increase in cylindrical tank, thus dv = 9π. For cylinder, V = π r 2 y = 400 π y thus dv = 400π dy and this yields 400π dy = 9π so, dy = 9 400 ft/min 2. 3 (a) G(3) = f(t) 1 (1)(1) 1(1) 3 0 2 2 (b) G inc so G or f + when 0 < x < 2.5 or 4.6 < x < 5 G con down when G or f so G or f dec when 2 < x < 4 Both: when 2 < x < 2.5 (c) x = 3, G(3) = 3/2, G (3) = f(3) = 1 so 2x + 2y 9 = 0 or y 1.5 = 1(x 3) Semester 1 Final Prep Worksheets Answers are on the worksheets.
