Question

The function h(s)=40−2s relates the height (h) of a shipping container in feet in relation to the time (s) that it is being lowered onto the carrier in seconds.

Find h(2) and interpret your solution in the context of the problem.
Find the value of s when h(s)=30 and interpret your solution in the context of the problem.

Answer 1

This looks like the same problem you sent already, so I will be copying my original answer.

Function is h(s) = 40-2s

H(2) = 40-(2)(2)

H(2) = 40-4 = 36

Because the function represents height and time, we can say after 2 seconds the height in feet is 36. --> For H(2)

We need to set 40-2s = 30 for h(s)=30

30-40 = -10

-2s = -10 Divide both sides

s = 5
