Answer:
The pythagorean theorem
Step-by-step explanation:
If the length and width of a rectangle are given, then you can use the pythagorean theorem to calculate the length of the diagonal which can otherwise be called the hypothenus since it forms a right triangle.
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
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
We know p is 1.5 so we have
