2 / 3 of 4 = ( 2 x 4 ) / 3 = 8 / 3 ;
the answer is simple and easy. why do you ask such question.
anyway answer is D i.e. 6l²(6*7*7)
Answer:
4x + 12 = -4
4x = -16
x = -4
Step-by-step explanation:
Have a great day :)
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.
Answer:
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 =
- 12
