what are the equations for the asymptotes of this hyperbola?
Answer:
D
Step-by-step explanation:
The question is on asymptotes of a hyperbola
General equation for a hyperbola is; (x-h)² /a² - (y-k)²/b² =1
given y²/36 - x²/121 =1
then h=0 and k=0 thus Center of hyperbola= (0,0) at the origin.
b²=36,b⇒6 a²=121, a⇒11
Vertices of hyperbola v=( h+a, k) and (h-a, k) = (11,0) and (-11, 0)
Equation of asymptotes is given by;
y=k ± b/a (x-h) and we have found that a=11 and b=6
hence y=0 ± 6/11(x-0)
y=6/11 x and y= -6/11 x
Answer: Option D
[tex]y=\frac{6}{11}x[/tex]
and
[tex]y=-\frac{6}{11}x[/tex]
Step-by-step explanation:
We know that the general equation of a hyperbola with transverse vertical axis has the form:
[tex]\frac{(y-h)^2}{a^2}-\frac{(x-k)^2}{b^2} =1[/tex]
Where the point (h, k) are the coordinates of the center of the ellipse
2b is the length of the transverse horizontal axis
2a is the length of the conjugate axis
The asymptotes are lines to which the hyperbola graphic approaches but never touches.
The asymptotes have the following equation
[tex]y -y_1=\±m(x-x_1)\\\\[/tex]
Where
[tex]m=\frac{a}{b}\\\\y_1 = h\\\\x_1 = k[/tex]
In this case the equation of the ellipse is:
[tex]\frac{y^2}{36} -\frac{x^2}{121}=1[/tex]
Then
[tex]h=y_1= 0\\\\k =x_1= 0[/tex]
[tex]m = \frac{\sqrt{36}}{\sqrt{121}}[/tex]
The asymptotes are:
[tex]y -0=\±\frac{\sqrt{36}}{\sqrt{121}}(x-0)\\\\[/tex]
[tex]y=\±\frac{6}{11}x[/tex]
