# If Z varies inversely as W, and Z=30 when W=0.3 how do you find Z when W=30?

To find Z when W=30, we can use the inverse variation equation. The equation for inverse variation is Z = k/W, where k is the constant of variation.

First, we need to find the value of k. We can do this by substituting the given values of Z and W into the equation.

30 = k/0.3

To solve for k, we can multiply both sides of the equation by 0.3:

k = 30 * 0.3

k = 9

Now that we have the value of k, we can substitute it back into the inverse variation equation to find Z when W=30.

Z = 9/30

Z = 0.3

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.
