here is all you need to answer this question: $\large \frac {(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2}=1$ where (h,k) is the center vertices for this ellipse: (h,k$$\pm$$b) length of the minor axis: 2a length of major axis: 2b foci: (h,k$$\pm$$c where $$\large c^2 =b^2-a^2$$

2. dpaInc Group Title

let's find (h,k) first... h= k= ??

3. dpaInc Group Title

look at your equation and match it up with the one i wrote... what matches with h and k?

4. mj.jones90 Group Title

please hurry i have to have this done in 5 minutes or i fail1!

5. mj.jones90 Group Title

and thank you! :D

6. mj.jones90 Group Title

idk what?

7. dpaInc Group Title

$$\large \frac {(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2}=1$$ $$\large \frac {(x+5)^2}{5^2}+\frac{(y-7)^2}{12^2}=1$$

8. mj.jones90 Group Title

oh ok

9. mj.jones90 Group Title

so what are the lengths without vvariables? o.O

10. dpaInc Group Title

for the minor axis, its 2a for the major axis, its 2b you need to tell me what a and b are....

11. mj.jones90 Group Title

3 minutes!!!!!

12. mj.jones90 Group Title

but what about the ellipse that is nothing but variables?

13. dpaInc Group Title

a is 5 b is 12

14. mj.jones90 Group Title

and am i allowed to have variable in the legths?

15. dpaInc Group Title

the equation tells you everything you need to know..... you can identify all these quantities i'm asking for just by looking at your equation...

16. dpaInc Group Title

i already gave you a and b...

17. mj.jones90 Group Title

so 2a is 10?

18. dpaInc Group Title

yes.

19. mj.jones90 Group Title

and 2b is 24?>

20. dpaInc Group Title

yes

21. mj.jones90 Group Title

and the foci and eellipse?

22. mj.jones90 Group Title

what is c?

23. dpaInc Group Title

use the relation i showed u.... in the first post...

24. dpaInc Group Title

you already know what a and b are.. you can find c...

hmmm i really do not know this plus i am slightly brain dead btw r u a guy or girl

26. mj.jones90 Group Title

dont i just have get the square roote of c^2 and since c^2=119 than the answer would be 10.9? right?

27. mj.jones90 Group Title

just wanna know

29. mj.jones90 Group Title

why?

30. mj.jones90 Group Title

dpanlc?

31. mj.jones90 Group Title

u there?

idk so i dnt get it wrong

33. mj.jones90 Group Title

reaally/?

34. mj.jones90 Group Title

well i'm a girl....soooooooo
