(c) Is the amount of unprocessed gravel at the plant increasing or decreasing at time t5 hours Show the work that leads to your answer. (b) Find the total amount of unprocessed gravel that arrives at the plant during the hours of operation on this workday. Write, but do not solve, an equation involving one or more integrals that gives the time w when the pipe will begin to overflow. Using correct units, interpret your answer in the context of the problem.

For t > 8, water continues to flow into and out of the pipe at the given rates until the pipe begins to overflow. (d) The pipe can hold 50 cubic feet of water before overflowing. (c) At what time t, 0 ≤ t ≤ 8, is the amount of water in the pipe at a minimum? Justify your answer. (b) Is the amount of water in the pipe increasing or decreasing at time t 3 hours? Give a reason for your answer. The graph of f, the derivative of the function f, is shown above. Show Video Lesson AP Calculus AB Multiple Choice 2012 Question 80 80. (a) How many cubic feet of rainwater flow into the pipe during the 8-hour time interval 0 ≤ t ≤ 8? Which of the following gives the average velocity of the particle from time t 0 to time t 8. There are 30 cubic feet of water in the pipe at time t = 0. The pipe is partially blocked, allowing water to drain out the other end of the pipe at a rate modeled by D(t) = -0.04t 3 + 0.4t 2 + 0.96t cubic feet per hour, for 0 ≤ t ≤ 8. Abstract The purpose of this research is to identify and describe the changes to the AP Calculus AB test from its inception in 1955 to the present. The rate at which rainwater flows into a drainpipe is modeled by the function R, where cubic feet per hour, t is measured in hours, and 0 ≤ t ≤ 8.Questions and Worked Solutions for AP Calculus AB 2015ĪP Calculus AB 2015 Free Response Questions - Complete Paper (pdf)ĪP Calculus AB 2015 Free Response Question 1
