Best ResponseYou've already chosen the best response.0so would the center be (0,0) ??

Best ResponseYou've already chosen the best response.0okay so how do i write this equation?? oh the y axis?

jim_thompson5910

Best ResponseYou've already chosen the best response.1so the minor axis is vertical

jim_thompson5910

Best ResponseYou've already chosen the best response.1the major must be horizontal

Best ResponseYou've already chosen the best response.0ohh okay :) so its on the major axis?

jim_thompson5910

Best ResponseYou've already chosen the best response.1no they are on the minor axis because they are covertices

Best ResponseYou've already chosen the best response.0idk :/ how do i find that?? i just know the major axis is 10...

Best ResponseYou've already chosen the best response.06? so is 6 the length of the minor axis?

jim_thompson5910

Best ResponseYou've already chosen the best response.1cut that in half to get 3 that's the length of the semiminor axis

jim_thompson5910

Best ResponseYou've already chosen the best response.1since the minor axis is vertical, this value of 3 corresponds to the value of b (which is paired with the y term below) (xh)^2/(a^2) + (yk)^2/(b^2) = 1

jim_thompson5910

Best ResponseYou've already chosen the best response.1you know the center is (0,0) because you just found this, so (h,k) = (0,0)

Best ResponseYou've already chosen the best response.0okay :) so far we have this? (x0)^2/(a^2) + (y0)^2/(3^2)=1 ??

Best ResponseYou've already chosen the best response.1good, the only thing you need is 'a'

Best ResponseYou've already chosen the best response.0how do we find that? do we square root 10? if so, can i just write sq.rt.10?

jim_thompson5910

Best ResponseYou've already chosen the best response.1no, the length of the major axis is 10 the length of the semimajor axis is ____

Best ResponseYou've already chosen the best response.0okay so is this my final equation??dw:1356131103670:dw is that it?? or do i need to simplify it more?

jim_thompson5910

Best ResponseYou've already chosen the best response.0but when it says write the equation, what format do they want it in?

jim_thompson5910
 2 years ago
Best ResponseYou've already chosen the best response.1there are many formats, but that's probably the best one

jim_thompson5910

Best ResponseYou've already chosen the best response.1because you can tell it's an ellipse and you can use it to read off the center, major axis, minor axis lengths, etc etc
