Question
To begin a football game, a kicker has to kick off. The football follows the path h(x)=−1/30x(x−61) , where h(x) is the height of the football and x is the horizontal distance it has traveled in yards. Solve the equation to determine how far the ball will have traveled when it hits the ground.

To determine how far the ball will travel before hitting the ground, we need to solve the equation:
\[
0 = -\frac{1}{30}x(x - 61)
\]
We can start by multiplying both sides by \(-30\) to eliminate the fraction:
\[
0 = x(x - 61)
\]
Now we set the expression equal to zero:
\[
x(x - 61) = 0
\]
This product will equal zero when either of the factors is equal to zero. Therefore, we can set each factor to zero:
1. \(x = 0\)
2. \(x - 61 = 0 \Rightarrow x = 61\)
The solutions to the equation are \(x = 0\) and \(x = 61\).
The \(x = 0\) solution corresponds to the initial position of the ball at the kickoff, while \(x = 61\) corresponds to the position where the ball hits the ground.
Thus, the ball will have traveled **61 yards** before hitting the ground.
\[
0 = -\frac{1}{30}x(x - 61)
\]
We can start by multiplying both sides by \(-30\) to eliminate the fraction:

0 = x(x - 61)

2. \(x - 61 = 0 \Rightarrow x = 61\)

The \(x = 0\) solution corresponds to the initial position of the ball at the kickoff, while \(x = 61\) corresponds to the position where the ball hits the ground.
Thus, the ball will have traveled **61 yards** before hitting the ground.
