B. Multiplying by 45 is the same as multiplying by 80%.
The answer is 150 because
5*30
shortcut: 5*3=15
add the zero from the 50
150 is your answer..
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

The square root of -1 “i”
