Answer:
ummm I think this is obvious
Step-by-step explanation:
2 circles in each group, shade in one group of 2.
Using the given values from the problem and the illustration, three points are known which are (0,0), (6.5,-31), (-6.5,-31). The first step in solving this problem is to determine the equation of the parabola.
y = ax²
-31 = a(6.5)²
-31 = 42.25a
a = -31/42.25
a = -124/169
Therefore, the equation of the parabola is y = (-124/169)x². The value 4.5 is then substituted in the equation as x to get the answer which is 16.14 meters.
It is written as 35% or 0.35

Twice each side:
4*3*2 + 7*3*2 + 7*4*2 = 122
