If x is direct proportional to y cube and x=32 when y=2
1 answer:
Answer:
1x=864,
2y=3
Step-by-step explanation:
y=6,x=?
if x is directly proportional to y^3 &if (when x=32, y is=2) we can understand that x=4y^3
1,x=4y^3
x=4(6^3)
x=4(216)
x=864
2,x=4y^3
108=4y^3
108/4=4y^3/4
27=y^3
√27=y
y=3
i think it is easy to understand,but if the answers are not clear you can ask me &i hope it helps you
