Answer:
The width of the garden is 7 feet.
Step-by-step explanation:
If the area is 56 feet, and the length is 8 feet, we can put this into the area equation.
Area = width * length
A = wl
Substitute variables.
56 = 8w
Divide by 8.
7 = w, or w = 7.
The width of the garden is 7 feet.
Average value is the integral divided by the interval length. Thinking in terms of area, the integral is the total area, and a rectangle with that same area would have width of the interval, height the average value
<span>Int(15 - 15e^(-t/2))[0,4] </span>
<span>= 15t + 30e^(-t/2)[0,4] </span>
<span>= (15*4 + 30/e^2) - (0 + 30) </span>
<span>= 60 + 30/e^2 - 30 </span>
<span>= 30(1 + 1/e^2) </span>
<span>Average value = 7.5(1 + 1/e^2)
So, the answer is A</span>
