finding the equation for the ellipse and what the coordinates are for the vertices

we proved in class that the distance from the focus to the center of an ellipse is square root of a squared minus b squared. if an dentists lamp has a reflector that takes its shape from an ellipse...

full explanation please

The conic section that is being used has to be a parabola, circle, ellipse, or hyperbola.

I've got two LORAN stations A and B that are 500 miles apart. A and B are also the Foci of a hyperbola. A ship at point P (which lies on the hyperbola branch with A as the focus) receives a nav signal...

(y+3)^2/25+(x-2)^2/16=1

Here are the choices: A: C(-5,-7) d=9 B: C(-5,-7) d=18 C: C(5,7) d=9 D: C(5,7) d=18

25x2+50x+169y2-4200=0 what is true a.the lenght of the conjugate axis is 10 b. The graph has a vertex at (12,0) c. The graph has a focus at (13,0 d the center of...

X-2y2=0 which of the following is true ? a. The graph is an ellipse centered at (0,0) b. The graph is a hyperbola that passes through (0,0) and (2,1) c.the length of the minor axis is...

X2 + 4x +8y -20=0 which of the following is true a. The graph is a parabola with its vertex at (-2,3) b.the gragh is an ellipse centered at (-2,3) c. The graph is a hyperbola...

determine an equation for the parabola with focus (3,1) and directrix x=9

Write its equation in standard form Sketch the graph identify the center, vertices, co-vertices,foci, and asymptotes

7x^2 - 6sqrt(3)xy + 13y^2 - 16 = 0 Please give me the answer in detail and in graph, been trying to do this for hours and I don't know how to do it ...

Two people standing 10,000 feet apart see a lightning strike. One person is 5500 feet farther from the lightning strike than the other. The possible locations form a hyperbola with the two people...

I have a test on chapter 9 in Algebra 2 tomorrow and I don't understand how to find the focus, directrix, and axis of symmetry of a equation. For example: -5+1/3y2=0
