Answer:

Step-by-step explanation:
Because this quadratic equation would have the curve-down form of:

where a and b are positive coefficient.
If we let the peak (250 ft) of the curve be at x = 0. Then


Also at the begins and ends, thats where y = 0, the 2 points are separated by 100 ft. So let the begin at -50 ft and the end at 50ft. We have



Therefore, the model quadratic equation of our path would be

So we have to find b we are going to try to isosiate b
4b - 3 > -1 now we are going to isosiate the b so add 3 from both side and get 4b > 2
Answer:
Step-by-step explanation:
15 x 7 = 105
The gap is either 9 x 7 =63 or 12 x 7 = 84
105 - 84 = 21
105 - 63 = 42
So the shaded area is either is 21 or 42
