The point $P\left(-9,\frac{36}{5}\right)$P(9,365) lies on a conic section with a focus at $\left(12,0\right)$(12,0) and directrix at $x=\frac{75}{4}$x=754.

Find the eccentricity of the conic section.

Consider the hyperbola with the equation $16x^2-9y^2=144$16x29y2=144.

The point $P\left(\frac{17}{2},-\frac{45}{8}\right)$P(172,458) lies on a conic section with a focus at $\left(5,0\right)$(5,0) and directrix at $x=\frac{16}{5}$x=165.
