Problema Solution
A cherry pie is removed from a 360 degree (Fahrenheit) oven. The temperature of the pie is modeled by the function equation T(t)=72+228e^(-0.068t)
where t represents the time in minutes since the pie was removed from the oven.
About how many minutes are required for the pie to reach 125 degrees Fahrenheit?
Answer provided by our tutors
T(t)=72+228e^(-0.068t)
125=72+228e^(-0.068t)
53=228e^(-0.068t)
0.232456=e^(-0.068t)
t=21.456 minutes
