So i'm hoping im making a stupid mistake in my algebra: (4.275*10^-5)/((0+X)^2) = (3.195*10^-5)/((.185-x)^2) Solve for X and lemme know whatcha get. __________________ __________________ Karma/rep is always appreciated 01010010011001010110010001100010011001010110000101 11001001100100 010011110111010101110100 There are only 10 kinds of people in this world.

In Y1, put (4.275*10^-5)/(0+X)^2)-(3.195*10^-5)/(.185-x)^2) in Y2, put 0 Then press Zoom->0: Fit After it graphs go to 2nd->Trace-> 5: Intersect. When it prompts for first curve, press enter. Second curve, press enter. Then when it asks to Guess move the cursor over to where it looks like the line intersects and press enter. Then it will give you the value of X. I got 1.365, but I might be wrong. __________________

This is like a foreign language to me.
