Hello all,

I have one more that I tried but I dont think i did it right.

1. Coroners often use liver temperature and Newton's Law of Cooling to estimate time of death. Newton's Law of Cooling is given by the fomula:

T- T(base R) = {T (base 0) - T(base R)}e^kt

where T is the temperature of the body at the time t, T(base R) is the room temperature, T(base0) is the body temperature at the time of death, and k is the relative rate fo cooling. A recently deceased body is found to be 28C at 3:30 pm, and 25C at 4:30 pm. The air temperature in the room is 20C. If the body's temperature was 37C at the time of death, approximately when did the individual die? (Hint: recall that logex= lnx)

Thanks,

David
