Oil is spilled onto a kitchen floor. The area covered by the oil at time t is given by the function A, where A(t) is measured in square centimeters and t is measured in seconds. Which of the following gives the rate at which the area covered by the oil is changing at time t=10 ?
Answer D
Correct. The derivative of the function AA evaluated at t=10t=10 gives the rate of change of the area covered by the oil at time t=10t=10
