Find the focus F and the equation of the directrix d of each parabola if its vertex is at the origin.
a. y^2 = 6x
b. y^2= -2/3x
c. 5y^2 – 3x = 0
d. x^2 = –36y
e. x^2 = –y
f. 2x^2 – 9y = 0

i do not know this sorry : (

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
