Answer:
C
Step-by-step explanation:
because you have to foil then do -b/2a
Ok so first, you need to figure out the change in elevation for each after one min. so we will write it as a ratio
10:-160 20:-300
So for the 10 min one, we will divide both sides by 10
1:-16 So the change in elevation per min. is -16
Now for the 20 one, we will divide by 20.
1: -15 So the change in elevation per min. is 15
So, the 10 min section of the walk the change of elevation was greater. Hope that helps! if you need me to explain something just ask!

Answer:
Step-by-step explanation:
Volume for a cone = 1/3 * pi * 
* h
Volume for a pyramid = 1/3 * area of base * h
4x4-12x2+9=0
Two solutions were found :
x = ±√ 1.500 = ± 1.22474
