A scientist is developing a parabolic object that is made up of mirrors and uses the sun's rays to focus heat on one particular location. To create a prototype of this object, she graphs a parabola on a coordinate plane that has a focus of (3,2)3,2 and a directrix of y=1y=1. This parabola can be represented by the equation (x−3)2=a(y−1.5)x-32=ay-1.5. Enter the value of a in the equation above.
