**finding directrix. Am I right?**

oh! Ok thank you. I already do have it graphed as that is required. Thank you for all the help.
*May 19, 2008*

**finding directrix. Am I right?**

the equation of the parabola is (y-5)^2=5(x+8). Now I asked this earlier but that thread is farther down so no one sees it. He said the directrix is -9.25 but I think it is -1.25. Am I right?

All you need to do is convert to moles AuCL3 and then use the mole ratio and convert back to grams Cl2 64.0*(1 mol/233g)*(3 mol Cl2/2mol AuCl3)*70.906gCl2= 29.214
*May 19, 2008*

**Algebra 2**

Sorry but I am trying to understand your reasoning for the directrix. How did you get -9.25. I would think it would be -1.25.

**Algebra 2**

When you say vertex, you mean the center so what about vertices and co-vertices. And there is only 1 foci?
*May 19, 2008*

**Algebra 2**

Another thing, would a=1.25? Because 4*1.25 equals 5
*May 19, 2008*

**Algebra 2**

Actually, I belive you made a mistake there. Multiplying both sides by five would get my -10y and therefor, I would add 25 to both sides right?
