Y is directly proportional to x squared if y=20 when x=2 find y when x= 5

y = 125

Step-by-step explanation:

Given that,

y is directly proportional to x² i.e.

k is a constant of proportionality

Put y = 20 and x = 2 in the given equation to find k.

Now put k = 5 and x = 5 in the given equation to find y.

So, the value of y is equal to 125.

step-by-step explanation:

irrational, cannot
