Suppose that r varies directly as p and inversely as q2, and that r = 27 when p = 3 and q = 2. Find r when p = 2 and q = 3.

Question

johnweldon1993 · Answer

$$\large r = \frac{kp}{q}$$

r = 27 when p = 3 and q = 2 so we can solve for 'k' (our constant of variation)

$$\large 27 = \frac{3k}{2}$$

solve for 'k' there

thank you

johnweldon1993 · Answer

That isn't everything...

Once you solve for 'k' there you will have the same equation

$$\large r = \frac{kp}{q}$$

And you will input p = 2, q = 3 and the 'k' you fund...and solve for 'r'
