Question 1168344: Translate the statement into an equation using “K” as the constant of proportionality?
I is directly proportional to the cube root of y if I= 5 when y=64 find I when y=8
Answer by Boreal(15235) (Show Source): You can put this solution on YOUR website!
I=ky^(1/3)
5=k*64^(1/3)=4k
k=5/4
use that in the second part
I=(5/4)*(8)^(1/3)
=5/2
