A ball is thrown vertically in the air with an initial velocity of 60 feet per second from an initial height of 6 feet. The equa
Novosadov [1.4K]

Answer:

  1. 1.875 seconds to reach the maximum height
  2. 62.25 ft

Step-by-step explanation:

The problem can be solved by putting the equation into vertex form.

  s - 6 = -16(t^2 -15/4t)

  s -6 -16(15/8)^2 = -16(t^2 -15/4t +(15/8)^2) . . . . add the square of half the x-coefficient inside parentheses and equivalent amount on the other side of the equation

  s -62.25 = -16(t -15/8)^2 . . . . write as a square, simplify the constant

  s = -16(t -1.875)^2 +62.25 . . . . put in vertex form

The vertex of the downward-opening parabola is at (t, s) = (1.875, 62.25).

1. It took 1.875 seconds for the ball to reach its maximum height.

2. The ball went up to 62.25 feet.

If I multiply any number by 1 whole, my product will be:
marusya05 [52]

Let a = any number

So, 1 times a = a.

In other words, any number times 1 = any number.

Two samples:

1. 45 x 1 = 45

2. -567 x 1 = -567

Understand?
