Question

A corpse was discovered in a motel room at midnight and uts temperature was 82°F. The temperature dropped to 80.5°F two hours later. Given k is a constant for the object in question, S is the surrounding temperature, t represents the time and theta(of time) is the temperature at the given time, Newton's Law of Cooling states: 
K(t1-t2)=-ln((theta)(t1)-S)/((theta)(t2)-S) 
Find the time of death to the nearest minute 
Find a function that graphs hours since death as a function of body temperature. 
Thanks ahead of time!

Are you confusing k and θ? I see no k in the function. It also appears you are missing some information. Ought we not to know S?
