Could you please tell me if this is correct?
If a cup of coffe has temperature 95 C in a room where the temperature is 20 C, then according to Newton's Law of Cooling, the temperature of the coffee after t minutes is T(t)=20+75e^-t/50. What is the average temperature of cofee during the first half hour?
int. 20+75e^-t/50 from 0 to 30
20t-3750e^u from 0 to 30
Thank you very much
