Answer: 4 seconds
Step-by-step explanation:
We have the equation that models the height of the golf ball in feet after being hit.
When the ball reaches the ground its height is equal to zero.
Then to solve this problem you must equal h to zero and solve the equation for the variable t
Take 16t as a common factor
The equation is equal to zero when t = 0 and when t = 4
t = 0 is at the instant in which the ball has just been hit and t = 4 seconds is the instant in which the ball touches the ground.
Then the answer is t=4 seconds

<h3>The answer is:</h3><h2>7.5 degrees</h2>
Point N is the image of M .
<h3>What is Perpendicular bisector?</h3>
Perpendicular lines are lines that intersect at a right (90 degrees) angle.
Given : P is a point on the perpendicular bisector, l, of MN.
To prove : PM = PN
A Reflection is a transformation in which the figure is the mirror image of the other. Every point is a mirror reflection of itself .
By the definition of reflection, point P is the image of itself ,point N is the image of M .
The line l acts as a Line of symmetry or axis of reflection.
Reflections preserve length so PM = PN.
Thus , point N is the image of M .
