To interpret \( h(1) \), we first need to evaluate the function \( h(t) \) at \( t = 1 \).
Given the function: \[ h(t) = -16t^2 + 5t + 15 \]
Substituting \( t = 1 \): \[ h(1) = -16(1)^2 + 5(1) + 15 \] \[ h(1) = -16 + 5 + 15 \] \[ h(1) = -16 + 20 \] \[ h(1) = 4 \]
Now, we can complete the statements:
The interpretation of \( h(1) \) is that at 1 second, Martha's height is 4 feet from the water's surface.
