Question

I have no earthly idea how to do this problem:
At 8:30 am a coroner was called to the home of a person who had dies in the night. In order to estimate the tome of death, the coroner took the person's body temp and at 9 am the temp was 85. 7 degrees F. The room temp stayed constant at 70 degrees and the decay model was -0.4. Find the approx. time of death.

Answer 1

does it say what the decay is in terms of? seconds? hours? minutes?
Basically, what it's saying is that the body loses 0.4 degrees every (unknown unit of time). A normal person has a body temp of about 98.6 degrees.
So, you set up an eqn to find how long the body must have been dead:

98.6-0.4t = 85.7
t= 32.25 seconds? hours? minutes? days? years? epochs?

Answer 2

actually, that answer doesnt make sense with any of that... since it says: "a person who had dies in the night."
if it was 32.25 mins then it would be in the morning (and 2 mins before she got called) if it were hours it would have happened yesterday O_o maybe i set the eqn up wrong.

Answer 3

*a person who had died in the night"..sry

Answer 4

lol i didnt even notice the typo, i just noticed it said it happened that night, which my answer conflicts with.
