Answer:
y=-3.5x^2+9.5x-4
Step-by-step explanation:
y=a*x^2+b*x+c
4=0+0+c => c=-4
2=a+b-4 =>a+b=6
1=4a+2b-4 => 4a+2b=5
2a+b=2.5
a+b=6
a=-3.5
b=9.5
It would take 5 times because if it goes 4 times it would reach 255 miles but if it goes 5 times it will pass the amount.
Answer:
the answer should be 4.71828182846
Answer:
Step-by-step explanation:

so for a triangle it's 1/2 base * height for the area
1/2 * 8 * 3 = 12
12*20=240 m^3
