Answer:

4feet

Step-by-step explanation:

Area of the trapezoid = 1/2(a+b)h

a and b are the sides

h is the height

Substitute the given values

Area of the trapezoid = 1/2(8+b)*4

24 = 1/2(8+b)*4

2(24) = (8+b) * 4

48 = 32 + 4b

4b = 48-32

4b = 16

b = 16/4

b = 4feet

Hence the window on top is 4feet wide

Write the inverse function for the function, ƒ(x) = 1/2x + 4. Then, find the value of ƒ -1(4). Type the answer exactly in this f
WINSTONCH [101]
We can get the inverse function by first setting f(x) = y, solving for x, and after that switching y and x. So, let's solve for x:
f(x)= \frac{1}{2}x+4
y= \frac{1}{2}x+4
2(y-4)=x
2x-4=y=f (x)^{-1}

Then, just plug in 4 for x, and solve:
2(4)-4= f (x)^{-1}
4=f (x)^{-1}

There you have your answer.
