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

This is approximately 32 minutes before he arrived or about 1:20 AM
1/4(4) goes on the y axis
Answer:
600
Step-by-step explanation:
What divided by 60 equals 10? In other words, you have an unknown number (X), and then if you divide that X by 60 you get 10. Then what is that X? Therefore, the answer to what divided by 60 equals 10 is 600.
That is the answer put anymore question if need help?
Yes because simplified 9/15 equals 3/5 and 6/10 also equals 3/5
