Cos[arcsin(1/4)]
First let's calculate arcsin(1/4)

arcsin(1/4) = 14.47751

2nd) cos(14.47751) = 0.968

Answer: 5 seconds

<u>Step-by-step explanation:</u>

Maximum height is the y-value of the vertex. The number of seconds at maximum height is the x-value (aka axis of symmetry).

h(x) = -2x² + 20x + 48

a=-2 b=20 c=48

Axis of symmetry: x = $\frac{-b}{2a}$

= $\frac{-20}{2(-2)}$

= $\frac{-20}{-4}$

= 5

Plug in 3 for x. 5(3) (-2(3) x 2) = 15(-6 x 2) = 15(-12) = -180.
