Question

What are the answeres to a and b using Newton's Law of Cooling? No answer for c is neccessary. 

A pizza pan is removed at 5:00 PM from an oven whose temperature is fixed at 400°F into a room that is a constant 71°F. After 5 minutes, the pizza pan is at 300°F. (a) At what time is the temperature of the pan 130°F? (b) Determine the time that needs to elapse before the pan is 170°. (c) What do you notice about the temperature as time passes? (a) The temperature of the pan is 130°F at PM. (Do not round until the final answer. Then round to the nearest minute as needed.)
