Question 927287: The latus rectum of a parabola is the line segment perpendicular to the axis of symmetry through the focus, with endpoints on the parabola. Find the length of the latus rectum of each parabola.
50. y= 1/8x^2
51. y-k= 1/4p(x-h)^2
THANKS SO MUCH

he latus rectum of a parabola is the line segment perpendicular to the axis of symmetry through the focus, with endpoints on the parabola. Find the length of the latus rectum of each parabola.
..
Form of equation for a parabola: (x-h^2=4p(y-k)
latus rectum or focal width=4p
..
50. y= 1/8x^2
x^2=8y
latus rectum=8
..
51. y-k= 1/4p(x-h)^2
(x-h)^2=4p(y-k)
latus rectum=4p
