Answer:
Step-by-step explanation:
Below is the screenshot with the parts I have divided the figure into.
First, lets solve the first part:
7x25 = 175 mi
Next part(Second part):
16x6 = 96 mi
Finally, #3:
11x3 = 33 mi
By dividing the rectilinear figure into 3 different parts and getting the area for each, now we add all three values:
175+96+33 = 304 mi
Don't forget the units!
So the answer is 304 mi squared
Hope this helps!

Answer:
21. y = 75000·0.935^t
22. after 74.6 days
23. y = 27.8112·1.18832^t
24. 18.8% per month
25. 1748
Step-by-step explanation:
22. It is convenient to use the graphing calculator to solve this problem. The number of days is where the exponential curve has the value 500. It is about 74.55 days. (see the first attachment)
__
23. y = 27.8112·1.18832^t (see the second attachment)
__
24. The rate of change is the difference between the base of the exponential and 1, often expressed as a percentage. The time period is the units of t.
(1.18832 -1) × 100% ≈ 18.8% . . . . per month
__
25. Evaluating the function for t=24 gives y ≈ 1748.30425259 ≈ 1748.
