Answer:
y = 4x + 20
Step-by-step explanation:
y = -8x + 12x +20
0.87 = 87/100 <=== this is the fraction
A ratio that compares two quantities measured in different units is a conversion factor!
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.
The probability is 4 out of 14
