Answer:1
Step-by-step explanation:
-5x=-2x-3
-5x+2x=-3
-3x=-3
X=1
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.

You have a right triangle therefore you can calculate the base as (9tan30)=sqrtof3 over 3
Area of triangle 1/2 bh = 1/2(sqrt3 over 3)
(9) As this is just 1 triangle you then need to multiply it by 2
bh = sqrt of 3 over 3 * 9</span><span>
