A golfer hits a golf ball toward the hole 55 yards away. The ball follows a parabolic path given by the function h (x) = -1/25x (x - 45), where h(x) is the height of the golf ball and x is the horizontal distance it has traveled. Solve the equation to determine how far the ball will have traveled when it hits the ground. How far will the ball need to roll to make it to the hole?

0 = -1/25x (x - 45)

The ball will hit the ground after it has traveled 45 yards. It will need to roll an additional 10 yards to reach the hole.
The ball hit the ground after it has traveled 30 yards. It will need to roll an additional 25 yards to reach the hole.
The ball will hit the ground after it has traveled 10 yards. it will need to roll an additional 45 yards to reach the hole.
The ball will hit the ground after it has traveled 25 yards. It will need to roll an additional 30 yards to reach the hole.

To determine how far the ball will have traveled when it hits the ground, we need to solve the equation:

\[
0 = -\frac{1}{25}x(x - 45)
\]

This equation can be factored as:

\[
0 = -\frac{1}{25}x(x - 45)
\]

Setting the product equal to zero gives us two solutions:

1. \( x = 0 \) (the starting position)
2. \( x - 45 = 0 \) which leads to \( x = 45 \)

Thus, the ball will reach the ground after traveling **45 yards**.

Now, since the hole is 55 yards away, we can determine how far the ball needs to roll after hitting the ground:

\[
\text{Distance to hole} = 55 \text{ yards}
\]
\[
\text{Distance traveled before hitting ground} = 45 \text{ yards}
\]
\[
\text{Rolling distance} = 55 - 45 = 10 \text{ yards}
\]

Therefore, the correct answer is:

The ball will hit the ground after it has traveled **45 yards**. It will need to roll an additional **10 yards** to reach the hole.
