Suppose you turn off the engine of your car when the temperature of the engine reaches 191 °F. If the outside temperature is a constant 66 °F, then the temperature T of the engine t minutes after you turn off the engine satisfies the equation below.
ln((T − 66)/125)= −0.07t

(a) Solve the equation for T.
T =

(b) Find the temperature of the engine 28 minutes after you turn it off. Give your answer to the nearest tenth of a degree.
°F=

law of cooling?

lgbasallote · Answer

for number 1 just isolate T

for number 2 substitute 28 into t

does that help? or do you need more help?
