Answer:
The constant of variation is 3
Step-by-step explanation:
Given.


And y is directly related to x
∝ 
Here k is constant of variation

--------------(1)
Put the
and
value in equation 1.


So, the constant of variation is 3.

well, for creating points, it gets set up as (x,y) which it lays out in perfet format, and if you need help graphing, i can try and create it.
Answer:
Step-by-step explanation:
V = l * w * h
27000ft3 = (2w) * w * 10ft
27000ft3 = 2w^2 * 10ft
2700 = 2w^2
1350 = w^2
W = 36.74
