Answer:
a) A=0.86
b) A=2.81
c) A=2.88
Step-by-step explanation:
The average of a functions can be written as:
(1)
a.) The second hour means that the interval of time is from 0 to 2 hours, so a=0 and b=2. Using the equation (1) we can calculate the average intensity.
Using integration by parts we can solve it.
,
,
(2)
Therefore, the average intensity at the second hour will be:
b) We can use the equation (2) to solve it. In this case the limits of integration will be a = 0 and b = 12 hours.
Therefore, the average intensity at the twelfth hour will be:
c) Finally, here a = 0 and b = 24 hour.
Therefore, the average intensity at the twenty-fourth hour will be:
