Question

What are the foci of.... (I have a picture of the equation)

Answer 1

wait how?

Answer 2

(–8, –5) and (2, –5)

(–8, 5) and (2, 5)

(–2, –5) and (8, –5)

(–2, 5) and (8, 5)

Answer 3

its okay! thanks! I just wanna know how to do it because I have another one that i cant do

Answer 4

i cant read the tops of fraction - what are they?

Answer 5

(x+3)^2/169 _ (y+5)^2/144=1

Answer 6

- not _

Answer 7

oh ok - i read the 169 as 100

foci are at sqrt(169 - 144) = +/- sqrt 25

Answer 8

which gives me +/-5 but how do I find the coordinate out of that?

Answer 9

(–8, –5) and (2, –5)

(–8, 5) and (2, 5)

(–2, –5) and (8, –5)

(–2, 5) and (8, 5)
like which one would that be^

Answer 10

cant be. Wouldn't it be the y coordinates?

Answer 11

idk Im just confused cause there is no 5 or -5 as a x value in my answer choices

Answer 12

ok first find foci of

X^2 + Y^2
--- --- = 1
169 144

foci of this is sort(169 - 144) = x = +5 and -5

Answer 13

now
X = x + 3 so x = +5 and x = -5 will move 3 units to left i.e. x = -8 and 2
similarly the y coordinate 0 will move -5 unit down ( because Y = y+5)

so foci are at (-8,-5) and (2, - 5)

Answer 14

thank you so so so much! I really appreciate it!
