Answer:
y=4
Step-by-step explanation:
We are given the expression:
We want to find when
equals 6. Therefore, we can plug 6 in for x.
Now, let's begin solving for y. First, multiply -3 and 6.
Next, add 18 to both sides of the equation. We add because 18 is negative and addition will cancel out the -18 on the left.
Finally, divide both sides by 9. We divide because y is being multiplied by 9, and division is the inverse of multiplication.
When x=6 in the equation, y is equal to 4.
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.
