Answer:
h = -0.0166t^2 + 30.
Step-by-step explanation:
The graph of the flight is a parabola which opens down and is symmetrical about the y axis, passes through the x axis at -42.5 and 42.5 and has a vertex at (0, 30).
So we have -a(t^2) + 30 = 0 where t is the time
(42.5)^2 * -a = -30 (42.5 as its 1/2 * 85).
a = 30/2806.25
= 0.01661
So the equation is height h = -0.0166t^2 + 30
<span>Simplifying
X + 4y = 36
Solving
X + 4y = 36
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '-4y' to each side of the equation.
X + 4y + -4y = 36 + -4y
Combine like terms: 4y + -4y = 0
X + 0 = 36 + -4y
X = 36 + -4y
Simplifying
X = 36 + -4y</span>
2,000 because 4 multiplied by 500 equals 2,000
