The Correct Option is B
Solution and Explanation
Differentiating the given equation of the curve
$4 x-6 y .(d y / d x)= 0$
$\therefore d y / d x=2 x / 3 y$
$\left(\frac{d y}{d x}\right)_{(3,2)}=\frac{2}{3} \cdot \frac{3}{2}=1$
$4 x-6 y .(d y / d x)= 0$
$\therefore d y / d x=2 x / 3 y$
$\left(\frac{d y}{d x}\right)_{(3,2)}=\frac{2}{3} \cdot \frac{3}{2}=1$

- The length of the latus rectum and directrices of a hyperbola with eccentricity $e$ are 9 and $x = \pm \frac{4}{\sqrt{3}}$, respectively. Let the line $y - \sqrt{3}x + \sqrt{3} = 0$ touch this hyperbola at $(x_0, y_0)$. If $m$ is the product of the focal distances of the point $(x_0, y_0)$, then $4e^2 + m$ is equal to ________.
- Consider a hyperbola \( H \) having its centre at the origin and foci on the \( x \)-axis. Let \( C_1 \) be the circle touching the hyperbola \( H \) and having its centre at the origin. Let \( C_2 \) be the circle touching the hyperbola \( H \) at its vertex and having its centre at one of its foci. If the areas (in square units) of \( C_1 \) and \( C_2 \) are \( 36\pi \) and \( 4\pi \), respectively, then the length (in units) of the latus rectum of \( H \) is:

Hyperbola
Hyperbola is the locus of all the points in a plane such that the difference in their distances from two fixed points in the plane is constant.
Hyperbola is made up of two similar curves that resemble a parabola. Hyperbola has two fixed points which can be shown in the picture, are known as foci or focus. When we join the foci or focus using a line segment then its midpoint gives us centre. Hence, this line segment is known as the transverse axis.
