A pan is heated to 409°F, then removed from the heat and allowed to cool in a kitchen where the room temperature is a constant 7

Irina18 [472]

Answer: C. $265.9^{\circ}F$

Step-by-step explanation:

Given: The formula below can be used to find D, the difference in temperature between the pan and the room after t minutes.

$D = 338e^{-0.03t}$

At t= 8 minutes, we get

$D = 338e^{-0.03(8)}\\\\\Rightarrow\ D = 338e^{-0.24}\\\\\Rightarrow\ D = 338(0.786627861067)\\\\\Rightarrow\ D = 265.88\approx265.9^{\circ}F$

The approximate temperature of the pan after it has been away from the heat for 8 minutes= $265.9^{\circ}F$
