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 would take him 2.5 hrs because when you divide 10 by 4 that's what you get

I cant do the rest because they have graph stuff :)
$ 2 each carnival ride + $8 spend at most $35
Rewrite that is
$2x + 8 ≤ 35
I hope this helped and that I was right, have a nice day.
The answer is D- an investment of 80,000 dollars was needed and they invested a ration of 3:4 (3/4 or 75%), you round up to 80
