Answer:
Step-by-step explanation:
Calculation
Divide your interest rate by the number of payments you'll make that year. ...
Multiply that number by your remaining loan balance to find out how much you'll pay in interest that month. ...
Subtract that interest from your fixed monthly payment to see how much in principal you will pay in the first month.
To answer the question above, divide the total amount raised (T) during fundraising by the number of future exhibits (n). The amount of money (m) each exhibit will receive,
m = T / n = ($1664) / 8 = $208
Thus, each exhibit will receive $208.
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
Both a and b.
