Help with application of ellipses and hyperbolas

OpenStudy (darkbluechocobo):

Find the equations of the asymptotes of the hyperbola described by the equation:

OpenStudy (darkbluechocobo):

\[\frac{ x^2 }{ 36 }-\frac{ (y+6)^2 }{ 11 }\]

OpenStudy (darkbluechocobo):

To find the asymptotes it is represented by the equation \[y=k+/-b/a(x-h)\]

OpenStudy (darkbluechocobo):

@freckles question what squares into 11

OpenStudy (darkbluechocobo):

also i forgot to add the = 1 to the equation

OpenStudy (freckles):

\[\frac{x^2}{6^2}-\frac{(y+6)^2}{(\sqrt{11})^2}=1 \\ \sqrt{11} \approx 3.317\]

OpenStudy (darkbluechocobo):

so just the sqrt 11 mang that was simple

OpenStudy (freckles):

yah

OpenStudy (freckles):

you could say a is sqrt(36) if you wanted

OpenStudy (darkbluechocobo):

\[k=6+/-\frac{ \sqrt11 }{ 6 }(x-0)\]

OpenStudy (freckles):

k is -6

OpenStudy (freckles):

oh and k is y lol

OpenStudy (freckles):

I'm sorry let me say that a different way your 6 is -6 since k is -6 the other thing I was trying to say is your named the equation k instead of y

OpenStudy (darkbluechocobo):

wowsers. the answer choices are this though which is why i am confused.

OpenStudy (freckles):

I guess you could call it k just don't give the name of the equation confused with what I was trying to tell you about your other k

OpenStudy (darkbluechocobo):

ohh so y=k and k =-6 or y = -6

OpenStudy (freckles):

k is -6 y is not really k y was the name of the equation before you or the software you are using named it k

OpenStudy (darkbluechocobo):

ohhh ok

OpenStudy (darkbluechocobo):

so the equation full and simplified would by y=-6+/- sqrt11/6x?

OpenStudy (freckles):

\[y=k \pm \frac{b}{a}(x-h) \\ k=-6 \\ b=\sqrt{11} \\ a=\sqrt{36}=6 \\ h=0 \\ y=-6 \pm \frac{\sqrt{11}}{6}(x-0) \\ y=-6 \pm \frac{\sqrt{11}}{6}x \] and the way I'm fixing to use k is totally different than the way I used it above they renamed your equation k instead of y this k is not the k from earlier \[k=-6 \pm \frac{\sqrt{11}}{6} x\]

OpenStudy (darkbluechocobo):

Alright. Thank you for explaining it :D

OpenStudy (freckles):

I think they meant y though

OpenStudy (darkbluechocobo):

Same I substituted for y in my first equation so i could get k to the other side which was indeed wrong

OpenStudy (freckles):

names can get confusing when you are using them for two different people

OpenStudy (freckles):

If you call two guys in a room Ted and then call on Ted to answer a question, the Teds can be confused on to whom you are speaking.

OpenStudy (darkbluechocobo):

loool great analogy 10/10

OpenStudy (freckles):

But it doesn't happen in math a lot.

OpenStudy (darkbluechocobo):

indeedly 2 teds very rare

OpenStudy (freckles):

lol I never known a ted

OpenStudy (darkbluechocobo):

same lol

OpenStudy (darkbluechocobo):

even 1 is rare :p

OpenStudy (freckles):

well john probably would have been better

OpenStudy (darkbluechocobo):

Hmm or will

OpenStudy (freckles):

yah
