Answer:
35
Step-by-step explanation:
Given yo = initial height the ball was thrown from.
Given vo = the initial velocity of the ball thrown
y = yo + (vo)t -16t^2 where t = time.
This is a parabola opening downward.
There is no y intercept as the ball is thrown upwards upwards not necessarily straight vertically.
The x-intercepts occur when the ball reaches the level the ball was thrown from or the ground.
