Answer:
1. h(x) = 2ˣ-7 :
2ˣ - 7 = 131,065
2^x = 131,072
x = 17
2. k(x) = -(x/2) - 1 = 17
x/2 = -18
x = -36
3. g(x) = -(x-2)² = -36
x - 2 = 6
x = 8
4. f(x) = √x = 8
x = 64
h(k(g(f(64)))) = 131,065

Answer:
2.5 times faster
Step-by-step explanation:
The cost per hour of method 1 is $25, while the cost per hour of method 2 is $10. In order for method 1 to be the better method, it must have a productivity, in units per dollar, that is equal or greater than the productivity of method 2:
The productivity A of method 1, in units per hour, must be 2.5 times greater than the productivity of method 2, which means that method 1 needs to be 2.5 times faster than method (2) to be the better method.
It's B
