Width: W
Length: L = W + 8
Perimeter = 2W + 2L = 2(W) + 2(W+8) = 184 (ft)
Solving for W: 2W + 2W + 16 = 184 (ft)
4W = 168 ft, and so W = 42 ft.
The length, L, is (42 + 8) ft = 50 ft. (answer)
Answer:
f−1(f(x)) = f(f−1(x)) = x
Step-by-step explanation:
Follow this simple example using the function f(x) = x + 2
f(x) = x + 2
NOw we find the inverse function f^(1)(x).
y = x + 2
x = y + 2
y = x - 2
f^(-1)(x) = x - 2
The inverse function is f^(-1)(x) = x - 2
Now we do the two compositions of functions:
f^(-1)(f(x)) = x + 2 - 2 = x
f(f^(-1)(x)) = x - 2 + 2 = x
Both are equal to x.
Answer: f−1(f(x)) = f(f−1(x)) = x
Answer:
25 hours on his week job and 15 hours on his weekend job
Steps
20 times 25 is 500 for pay
18 times 15 is 270 for pay
Just add them
