if Z varies inversely as w, and Z = 10 when w= .5 find Z when w= 8

Let's form an equation with a constant A



therefore

Where A is a constant

Now you can use your values for w and Z to find A, then you can use A and the new w to find the new Z using the same formula above.

Good luck!

I agree with capuchin and would like to applaud the use of . We're getting some major LaTeX practice around here lately!
