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
Can you send
picture or the question...please?
A=base*height*1/2 OR A=base*height/2
A=8*7/2
A=28
Green paper > 18 / 3 = 6 inch pieces
Red paper > 24 / 6 = 4 pieces of paper
total = 4 + 3 = 7 piece of paper in total :)
