Question

Help with Hyperbolas

Answer 1

For the following equation, find the foci of the hyperbola:

\[\frac{ (x-1)^2 }{ 9 }-\frac{ (y-5)^2 }{ 25 }=1\]

Answer 2

c=sqrt(9^2+25^2)

Answer 3

Here are some my handy notes for this

Answer 4

welp I got c =sqrt704 or aproximately 26.6

Answer 5

hold on let me work this out because my class never decimals for an answer while we did this

Answer 6

never got*

Answer 7

a^2=9 b^2=25
c^2=a^2+b^2
c^2=9+25
c^2=34
c=\[\sqrt{34}\]

Answer 8

Ohh I forgot to square s:

Answer 9

\[foci =(\sqrt{34},0)\]

Answer 10

is that an answer choice?

Answer 11

(1+sqrt34,5), (1-sqrt34,5

(1,5 + sqrt34), (1,5 - sqrt34)

(-3, 5), (5, 5)

(5, 5), (-4, 5)

Answer 12

(h,k +c), (h,k -c) i believe is what we use for foci so i believe it is B

Answer 13

hmmm

Answer 14

I would have to go with be as well

Answer 15

B i mean answer choice B

Answer 16

Thank you :D
