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

16 is the absolute value

step-by-step explanation:

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .

the answer would be 0.54
