Question

A pan is heated to 377°F, then removed from the heat and allowed to cool in a kitchen where the room temperature is a constant 76°F. The formula below can be used to find D, the difference in temperature between the pan and the room after t minutes.
D = 301e-0.05t

What is the approximate temperature of the pan after it has been away from the heat for 8 minutes?
A.
277.8°F
B.
201.8°F
C.
125.8°F
D.
525°F

Answer 1

A graph shows the appropriate choice to be
