Answer:
is equation of height of rocket.
Option D is correct.
Step-by-step explanation:
Given: A rocket is launched with speed 85 ft/s from a height 28 feet.
Launching a rocket follows the path of parabola. The equation of rocket should be parabolic.
Parabolic equation of rocket is
Formula: 
g ⇒ acceleration due to gravity (-32 ft/s)
v ⇒ Initial velocity (
)
h ⇒ Initial height (
)
h(t) ⇒ function of height at any time t
Substitute the given values into formula
D is correct.
w - width
3w - 1 - length
54 in - perimeter
w + w + (3w - 1) + (3w - 1) = 8w - 2 - perimeter
The equation:
8w - 2 = 54 <em>add 2 to both sides</em>
8w = 56 <em>divide both sides by 8</em>
w = 7
3w - 1 = 3(7) - 1 = 21 - 1 = 20
<h3>Answer: The length = 20 in.</h3>
NO. Sine is opposite/hypotenuse, so the answer should be 24/25

Answer:
The perpendicular equation is y = -3x -21
Step-by-step explanation:
Perpendicular lines have the exact opposite slope as the other equation and they never have the same y-intercept.
To find the perpendicular slope just look at the slope in the original equation and get the exact opposite.
First let's simplify the equation.
-5 + x = 3y (divide by 3 on both sides to get y by itself)
-5/3 + 1/3x = y or y = 1/3x + 5/3
The exact opposite of this slope would be -3.
Now plug in the point you were given so that we can find the y-intercept.
6 = -3(-9) + b (b = y-intercept)
6 = 27 + b (subtract 27 on both sides)
-21 = b
So the perpendicular equation looks like this.
y = -3x -21
