A cake recipe says to bake the cake until the center is 180°F, then let the cake cool to 120°F. The table shows temperature readings for the cake. a. Given a room temperature of 70°F, what is an
exponential model for this data set?
b. How long does it take the cake to cool to the desired
temperature?

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
