coverics at (3,7) and (3,-1) major axis of length 10
and can u show me how u did this

coverics?
OpenStudy (toxicsugar22):
covertices
OpenStudy (amistre64):
vertices; is this ellipse or hyperbola?
OpenStudy (toxicsugar22):
ellipse
OpenStudy (amistre64):
cant really determine an ellipse from just this info.... at best I can do is:
(x-3)^2 (y-3)^2
------ + ------ = 1
b^2 16

without knowing a focus; or eccentricity; there is no solid way to determine the 'b' value
OpenStudy (toxicsugar22):
ok
OpenStudy (toxicsugar22):
i got it
OpenStudy (anonymous):
yes there are infinitely many ellipses with major axis 10 and those vertices
OpenStudy (anonymous):
wait nevermind that

there's only one it has minor axis 6
OpenStudy (toxicsugar22):
vertics at (-4,9) and (-4,-3), Covertices at (-7,3) and (-1,3)
OpenStudy (toxicsugar22):
and cam u show me how u got that
OpenStudy (toxicsugar22):
thant is a question
OpenStudy (toxicsugar22):
can u help me with that

you look at the distance between vertices to find the axis lengths
OpenStudy (anonymous):
-7-1=6 and 9-(-3)=12
OpenStudy (anonymous):
the center is (-4,3)
OpenStudy (anonymous):
you can get your equation from that. (x+4)^2/(9)+(y-3)^2/(36)
OpenStudy (anonymous):
=1
