Identify the function that models ignoring air resistance a ball being thrown in the air with an initial velocity of 70 ft/s from a height of 5 feet

The required function is .

Explanation:

It is given that the ball being thrown in the air with an initial velocity of 70 ft/s and from a height of 5 feet. It means

Initial velocity = 70 ft/s

Initial height = 5 feet

The general function that approximate the height  in feet of a projectile on the earth after time t is

            .... (1)

Where, v₀ is initial velocity and h₀ is initial height.

Substitute and in equation (1).

Therefore, the required function is .

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.

the answer is b. glad to .
