A golf ball is struck by a 60-degree golf club at an initial velocity of 9898 feet per second. The height of the golf ball in f
eet is given by the quadratic function h left parenthesis x right parenthesis equals negative StartFraction 16 x squared Over left parenthesis 49 right parenthesis squared EndFraction plus StartFraction 84.9 Over 49 EndFraction xh(x)=− 16x2 (49)2+ 84.9 49x, where x is the horizontal distance of the golf ball from the point of impact. What is the horizontal distance of the golf ball from the point of impact when the ball is at its maximum height? What is the maximum height obtained by the golf ball?

The answer is "12 inches".
Step-by-step explanation:
Please find the image file of the graph.
We know so because the triangle is isosceles.
when
is called by
.
We know that since E and D are tangent points to a circle.
They have since D and F are tangent points only to circle.
Thus, if the perimeter is 32, the following is the result:
Therefore the length of
