Ellipse,foci,standard form?

Question

Consider the ellipse that has verticees at (0,5) , (0,-5) and foci at (0,3), and (0,-3) and write its equation in standard form.

ok see i did go bakc to the index of my book and found the page but when i went to the page they didnt show exactly teh same way that i have in the problem that .

they have :
ellipse 3x^2 + ...etc etc...like that and you have to write in standard way

Not like my problem ,now is it?

Answer 1

An ellipse looks like a flattened circle. It consists of all the points in a plane that satisfy the following: a+b=(twice the length of the semi-major axis), where a is the distance from one focus to the point on the ellipse, and b is the distance from the other focus to the same point on the ellipse. ELLIPTICAL GALAXY An elliptical galaxy is a galaxy that has the shape of an ellipse. It is also called an "E" or "E-type" galaxy. M87 and M32 are elliptical galaxies.

Foci means a foreign interest has the power, direct or indirect, whether or not exercised, and whether or not exercisable through the ownership of a US company's securities, by contractual arrangements or other means, to direct or decide matters affecting the management or operations of that company in a manner which may result in unauthorized access to classified information or may affect adversely the performance of classified contracts.
