Answer:

Step-by-step explanation:
Six trigonometric ratio:
Given that,
θ = angle, O= opposite side, A= adjacent side and H = hypotenuse.
H=11, sin θ=0.1736
We know that,




Perfect-square trinomials are of the form:

and are expressed in squared-binomial form as: 
The only possible choice for squared-binomial form is

Answer: correct choice is A.
The function
exists in a parabola.
The axis of symmetry of a parabola exists at the midpoint between the two real roots.
The roots exist the solutions of H(t) = 0
To estimate the roots equation exists 
Factor t(-16t + 64) = 0
t = 0 and -16t + 64 =0
-16t + 64 = 0
t = 64 / 16 = 4
t = 4
Then the two roots are t = 0 and t = 4, and the axis of symmetry exists
t = (0+4)/2 = 4/2 = 2
<h3>How to estimate the axis of symmetry?</h3>
The axis of symmetry exists at t = 2.
It represents the time at which the ball is at the higher point, the maximum height.
You can find the maximum height replacing t = 2 in the function H(t)

= 64 feet.
And you can also deduce that the second part of the flight will take 2 seconds, for a total flight time of 4 seconds.
