Question

If m varies directly as the square root of y, inversely as p^2, and inversely as n, what happens to m when y is quadrupled, p is tripled, and n is multiplied by 2?

Answer 1

Varies directly, means whatever happens to one happens to the other.

--If y is quadrupled, the square root of 4y would have you multiplying by 2.
--n is tripled, so you multiply by 3

Varies inversely means you do the opposite of the one to the other.

--If p is tripled then squared, it makes it 9 times as big as it was, so, inversely you divide by 9.

You are left with: m * 2 * 3 / 9

m is multiplied by 2/3

Answer 2

That's not one of my answer choices. ^^'

My answer choices are:
m is multiplied by 1/9
m is divided by 1/9
m is multiplied by 9
or It stays the same.
