Question

A forensic detective is called to the scene of a murder at 2am when she checks the temperature of the body, she finds that it is 80 degrees Fahrenheit. The temperature of the room in which the body is found is 65 degrees Fahrenheit.

If the detective uses Newtons law of cooling T(t)=Ta+(To-Ta)e^-0.1947t , what will she say was the time of death?
So far I wrote
t(0)=65-144e^-0.1947(0)

Answer 1

Am I right?
