Y is directly proportional to the square of x. When x=3, y=64 find the value of y when x=2 please im lowkey dying lol

y ∝ x²

so, y = kx²

With x = 3 and y = 64 we have:

64 = k(3)²

i.e. k = 7.1

so, y = 7.1x²

Then, when x = 2 we have:

y = 7.1(2)² => 28.4

Brainliest would be appreciated!

honesty mood

step-by-step explanation:

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.
