A) The differential equation comes from the fact that the rate of temperature change is proportional to the difference in temperatures.
B) Find general solution by separating variables and integrating
:
C) Initial condition is t=0, T = 87
D) Total time elapsed is 10 minutes, new temperature is 84
solve for alpha
E) Temperature function is:
solving for t
Plug in T = 98.6
