Question

Find the coordinate of the focus , axis of parabola , equation of the

directrix and the length of the latus rectum of the parabola ;

4 x2 – y = 0 . ​

Answer 1

Answer:

Area Of Sector

It consists of a region bounded by two radii and an arc lying between the radii. The area of a sector is a fraction of the area of the circle. This area is proportional to the central angle. In other words, the bigger the central angle, the larger is the area of the sector.

Answer 2

Step-by-step explanation:

4x²=y

x²=y/4

a=1/16

focus(0,1/16)

focus(0,1/16)axis of parabola X=0

focus(0,1/16)axis of parabola X=0directrix X+a=0

focus(0,1/16)axis of parabola X=0directrix X+a=0 =x+1/16=0=16x+1=0

Length of Latus rectum =4a =1/4
