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
8a²b + 3ab² - 9a²b
-a²b + 3ab²

Answer:
1. 22% of 10 = 2.2
2. 16% of 30 = 4.8
3. 25% of 50 is 12.5
4. 65% of 300 = 195
5. 10% of 450 = 45
HAHA, I KNEW IT!!!
