During a water balloon fight, Louisa uses a slingshot to fire a water balloon over the fortified wall of the opponent. When fired from the slingshot, the balloon will follow the path h(x)=−x^2+12x

, where h(x)
is the height of the balloon in feet, and x is the horizontal distance it will travel. To determine how far the balloon will travel before it reaches the ground, Louisa sets the height equal to zero and solves the quadratic equation 0=−x^2+12x

To determine how far the water balloon will travel before it reaches the ground, we need to solve the quadratic equation given by:

\[ 0 = -x^2 + 12x \]

We can rearrange this equation:

\[ -x^2 + 12x = 0 \]

Factoring out the common term \( x \):

\[ x(-x + 12) = 0 \]

This gives us two potential solutions:

  1. \( x = 0 \)
  2. \( -x + 12 = 0 \) which simplifies to \( x = 12 \)

The first solution, \( x = 0 \), represents the point where the balloon is released (initial position). The second solution, \( x = 12 \), represents the distance at which the balloon hits the ground.

Therefore, the balloon will travel 12 feet before it reaches the ground.
