## anonymous one year ago Help please?? <3 What are the foci of the following graph?

1. anonymous

2. xapproachesinfinity

first you need to find the focal length $f=\sqrt{a^2+b^2}$ a=5 b=2

3. xapproachesinfinity

|dw:1434515931890:dw| that segment is the focal length once you found it you can find the coordinates of the two foci

4. anonymous

I got f=sqrt(29) or f≈5.38516481 but I don know what to do after that
