Answer:
(c) f(x) at (70, 55)
Step-by-step explanation:
The point (70, 55) is not on g(x), which increases from a minimum of 899.5. Obviously, 55 is less than 899.5, so f(x) at (70, 55) has a lower minimum.
For this case we have the following expression:
1 / z = (4/5) / (8)
Rewriting we have:
1 / z = 4/40
1 / z = 1/10
Clearing the value of z we have:
z = 10
Answer:
The value of z for this case is given by:
z = 10
