$h(x)=-16x^{2}+100x+10$
The quadratic function above models the height above the ground $h$, in feet, of a projectile $x$ seconds after it had been launched vertically. If $y=h(x)$ is graphed in the $xy$-plane, which of the following represents the real-life meaning of the positive $x$-intercept of the graph?
Difficulty: Hard
A:
The initial height of the projectile
B:
The maximum height of the projectile
C:
The time at which the projectile reaches its maximum height
