# If r varies jointly as p and q and inversely as t, then how do you find an equation for r if r=6 when p=8, q=−3, and t=3?

The equation for r can be found by using the formula for joint variation and inverse variation. The equation is r = k(pq/t), where k is the constant of variation. To find the value of k, substitute the given values into the equation and solve for k. In this case, k = r(pt/q) = 6(8*−3/3) = -48. Therefore, the equation for r is r = -48(pq/t).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
