A volleyball was passed from one player to another with an initial velocity of 28 feet per second from an initial height of 3 feet. The function h(x) = -16x2 + 28x + 3 models the height, in feet, of the volleyball x seconds after it was passed. What was the maximum heigh
of the volleyball?

this was already solved by me with a different person. if you look it up in the search bar at the top of the page, you will get the answer.

step-by-step explanation:

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
