The height of an arrow can be modeled by the equation is , where t represents the time in seconds and h is height in feet.

Factor by using the GCF.

.

Ignoring the height of the archer is zero, so .

Apply zero product property: .

So,

The first equation, .

Solve the second equation, .

Add t from each side.

So, the arrow hits the ground after 4 seconds.

So, the arrow hits the ground after 4 seconds.
