A football is kicked toward the goal. The height of the ball is modeled by the function h(t) = −16t2 + 64t, where t equals the time in seconds and h(t) represents the height of the ball at time t seconds. What is the axis of symmetry, and what does it represent?

A. t = 2; It takes the ball 2 seconds to reach the maximum height and 2 seconds to fall back to the ground.
B. t = 2; It takes the ball 2 seconds to reach the maximum height and 4 seconds to fall back to the ground.
C. t = 4; It takes the ball 4 seconds to reach the maximum height and 4 seconds to fall back to the ground.
D. t = 4; It takes the ball 4 seconds to reach the maximum height and 8 seconds to fall back to the ground.

step-by-step explanation:

it has changed from the width and the height.

step-by-step explanation:

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
