Question 831602: Given the following information, write each ellipses equation in standard form. The vertices for this equation is (12,0),(-12,0) and the focii for this equation is (2 sqrt.11,0), (-2 sqrt.11,0). What will the equation in standard form be?
This is the question. Thank you for taking your time to help me with this problem!!!

Question 832240: How do you find the P and the directrix of the equation of a parabola with its focus on (4,-2) and a vertex of (4,-4)?
I tried solving for P but I don't know if it's correct. Here's my solution for P:
Since focus is (h + P, k) in terms of y or (h, P + k)in terms of x, I don't know if the equation is in terms of y or x, so I just made a guess, so: (4 + P, -4); P=-4 or (4, P - 4); P=4?
And also, how do you find P if vertex is at (2,1) and the directrix is at x = -2?
I'm really confused in finding for P but I understand how the basics work in conic sections. Your help will be really appreciated.

Question 835206: f(x)=-6x^2-4x-5
This is what I have gotten so far:
-b/2a= -(-4)/2(-6)= 4/-12= (-1/3,
y=-6(-1/3)^2-4(1/3)-5
y=-6(-1/9)-4(1/3)-5
y= -6/9-4/3-
I'm still trying to find the y-coordinate. I'm not sure if I need to find the common denominator or what. Please help me?

Question 835350: Hey. My name is Anne. Nice to meet your lovely self. ^_^
Conics confuse me completely. Right now my class is on ellipses. So my question is how do I find an equation of an ellipse? It gave me a graph, and a couple points. The major axis is vertical, and the vertex is (0,10) and (0,-10). The focus is at (0,8) and (0,-8).
I know there's some kind of equation to put these numbers in, but somehow that did not end up in my notes! :(
While I'm asking, how would I do this when the major axis is horizontal? (I know that's asking 2 questions. I understand if you can't, or won't answer that one. I just need the equation.)

Question 837764: I'm a little bit confused as to what I am really doing. A few classmates had said to use the foiling method but it does not look right. The directions state: Describe how to transform the parent function y=x2 (sqaured) to the graph of each function below. Graph both functions on the same axes...

Question 838333: Hi! I seem to always have trouble with conic sections so I hope you can help!
my equation says 2x^2+7y^2=14 now find e
I know that to find the eccentricity the equation is e=c/a
I don't understand where to find or how to get "c" and "a" in this problem.
Thank you so much for your help, it is greatly appreciated!!
