The rate at which gasoline flows out of a tank, in gallons per hour, is given by a differentiable function G of time t. The table below shows the rate as measured every 4 hours for a 24-hour period: t (hours) 0 4 812 16 20 24 G(t) (gallons 12.2 12.1 11.8 10.4 10.8 11.6 12.2 per hour) Part A: Estimate G'(10). Show the work that leads to your answer. Part B: Is there some time t, for 0 < t < 24, such that G'(t) 0? Justify your answer. 5.
