Question

what is a and b in the following equations

Answer 1

^^^^^

Answer 2

how did you get that because I have a couple of question like that and i wanna Know how to solve for them

Answer 3

The general form of a hyperbola that opens upwards and downwards is in the form


(y-k)^2/(b^2)-(x-h)^2/(a^2)=1


Notice how the values of 'a' and 'b' correspond to x and y respectively.


In the case of (y^2)/(9) - (x^2)/(4) = 1, we can rewrite it as (y^2)/(3^2) - (x^2)/(2^2) = 1


So we can see that a = 2 and b = 3

Answer 4

Thank you soo much...Im almost getting it-

Answer 5

oh sorry, mybad! Seems I was a biy confused...

Answer 6

that's great

Answer 7

its ok @slaaibak you werent the only one lol

Answer 8

@jim_thompson5910 you had the numbers mixed up a=3 and b=2

Answer 9

No, 'a' corresponds with x and 'b' corresponds with y. Unless your book is doing it the other way around.

Answer 10

yea remember a^2=9 which equals 3
and b^2=4 which equals 2
so a=3
and b=2

Answer 11

So it looks like your book is doing it the other way around.

Answer 12

well Im home schooled for now, but yea
