Step-by-step explanation:
Since the focus lies on the x axis, and the diretcrtirx is a vertical line, we have a sideways parabola so we have the equation
![(y - k) {}^{2} = 4p(x - h)](https://tex.z-dn.net/?f=%28y%20-%20k%29%20%7B%7D%5E%7B2%7D%20%20%3D%204p%28x%20-%20h%29)
where h,k is the vertex and
p is the distance from the vertex to the focus or the distance fromcthe vertex to the directrix.
Since the focus is 1.5, and the directrix is -1.5 the vertex is (0,0) so we have
![y {}^{2} = 4px](https://tex.z-dn.net/?f=y%20%20%7B%7D%5E%7B2%7D%20%20%3D%204px)
We know p is 1.5 so we have
![{y}^{2} = 6x](https://tex.z-dn.net/?f=%20%7By%7D%5E%7B2%7D%20%20%3D%206x)
![\frac{1}{6 } {y}^{2} = x](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B6%20%20%7D%20%7By%7D%5E%7B2%7D%20%20%20%3D%20x)

Answer:
first option
Step-by-step explanation:
Given 2 secants to a circle from an external point, then
The product of the external part and the whole of one secant is equal to the external part and the whole of the other secant, that is
PQ(RP) = PS(TP)
