Aball is thrown vertically upward. after t seconds, its height h (in feet) is given by the function h(t) = 60t - 16t^2 . what is the maximum height that the ball will reach?
do not round your answer.

56.25 feet.

Step-by-step explanation:

For a Quadratic function in the form , if then the parabola opens downward.

Rewriting the given function as:

You can identify that

Since then the parabola opens downward.

Therefore, we need to find the vertex.

Find the x-coordinate of the vertex with this formula:

Substitute values:

Substitute the value of "t" into the function to find the height in feet that the ball will reach. Then:

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.
