The value of the computer decreased exponentially throughout the five-year period. What was the average annual amount of decrease in dollars per
year) over the two-year interval from t = 2 to t = 4?
(Note: Give the answer as a positive value.

See Explanation

Step-by-step explanation:

Incomplete question as the function is not given. So, I will give a general solution

Required

Determine the average rate of change from t = 2 to 4

Average rate of change is :

In this case: a = 2 and b = 4

So, we have:

Assume that the exponential function is:

f(4) and f(2) will be:

So:

Take LCM

So, the average rate of change is a decrease of 4/81

4a. is 3 miles every hour

4b. is 1/3 of an hour per mile

step-by-step explanation:

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
