Answer 1

Answer:

A

Step-by-step explanation:

The projectile motion of Jenny's dive can be represented by $-at^2 + v_0t + h_0$ where a is acceleration, v_0 is velocity, t is time, and h_0 is initial height.

Jenny's vertical height above the water is represented by $-16x^2+12x+10$. 10 is h_0 and is Jenny's initial height.
