A potato is placed in a preheated oven to bake. Its temperature P = P(t) is given by the following.
P = 400 − 325e-t/50
Here P is measured in degrees Fahrenheit and t is the time in minutes since the potato was placed in the oven.
1. What was the average rate of change per minute during the first 30 minutes? (Round your answer to two decimal places.)
2. What was the average rate of change per minute during the second 30 minutes? (Round your answer to two decimal places.)

The equation is 400-325^-t/50

anonymous · Answer

to find the average rate of change you need to first find the total change

anonymous · Answer

since its the first 30 minutes, you can do p(30) - p(0)
