If y varies inversely as x^2 and y = 3 when x = 18, what is y when x = 3? a. 6 b .108 c.54 d.27 select the best answer from the choices provided abcd

It is given in the question that

y varies inversely as x^2 and y = 3 when x = 18.

SInce y varies inversely as square of x, so the formula will be

Where k is the constant of proportionality .

Substituting the values of y and x, we will get

Multiplying both sides by 324,

So the equation will be

And when x equals 3, we will get

Therefore the correct option is B .

true
