99 POINT QUESTION
rewona [7]
We assume you intend h(t) to be the usual equation of ballistic motion
  h(t) = -16t² + 40t + 10

a. The function can be written in vertex form as
  h(t) = -16(t² -5/2t) +10
  h(t) = -16(t² -5/2t +(5/4)²) + 10 +5²
  h(t) = -16(t -5/4)² + 35
This is the vertex form a(x-h)²+k where (h, k) is the vertex of the parabola. The maximum height will be "k" for a < 0, which it is.

The ball's maximum height is 35 ft.


b. h(t) = 0 for the value of t that satisfies
  0 = -16(t -5/4)² + 35
  (t -5/4)² = 35/16
  t = (5 +√35)/4 ≈ 2.729
About 2.729 seconds have passed when the ball hits the ground.


_____
I find it convenient to let a graphing calculator tell you the answers to these questions. As above, the maximum height is the y-coordinate of the vertex. The elapsed time is the x-coordinate of the positive x-intercept.

A linear function is represented by the equation y = 12x + 8. What is the difference between the y-values of the function at two
Reil [10]

Answer:

  • 12

Step-by-step explanation:

<u>Let the consecutive x-values be n and n+1, then the difference between y-values:</u>

  • 12(n+1) + 8 - (12n + 8) =
  • 12n + 12 + 8 -12n - 8 =
