Answer:

4

Step-by-step explanation:

If f(x)= 108-kx, then all you have to do is plug in the given value of x which is -4, then equal it to the given value of 124.

108 - kx = 124\\108 - k(-4) = 124\\\\108 + 4k = 124\\\\4k = 124 - 108\\\\k = 16/4\\\\k = 4

Answer and Step-by-step explanation:

So, you would do 100 times 31.8, which is 3180, that'll be the area of the rectangle.

Now, the semicircles. They together form a circle.

So, we do pi times d (diameter), which is 3.14 times 31.8 = 99.852

Now we add them together.

99.852 + 3180 = 3279.85 (rounded to the nearest hundredth of a meter)

The rectangle area is 3180.

The Semi circles' combined area is 99.85.

<u>The total area of the figure is 3279.85.</u>
