the shape of the telescope is said to be a parabola. In this case, t<span>he general form which we will pattern our equation is y- k= 4a(x – h)^2
(h,k) or vertex = (0,0)
y = 4ax^2
We substitute x = 320/2 = 160, y = 46
46 = 4a (160)^2
46 = 4a (25600)
4a = 23/12800
hence the equation is </span>y = (<span>23/12800)</span>x^2

Step-by-step explanation:
In order to draw a perpendicular bisector you must have ruler , compass and a pencil.
Given nothing and we have to show the steps to draw a perpendicular bisector.
Perpendicular bisector is the line which divides the line into two equal parts and makes 90° angle on other line.
If we want to make a perpendicular bisector on a line then we have to follow the following steps:
1) First draw a line with the help of ruler on which we want to make perpendicular bisector.
2) Now take a compass and a pencil.
3) Put the pencil in the compass and strech the compass equal to half or little more of the length of the line.
4) Now put the compass on one end of the line and draw an arc on the line or may be just upward.
5) Now repeat the step 4 from other end.
6) Now draw a line from the point where two arcs intersects on the line.
7) It is the perpendicular bisector of the line.
Hence to draw a perpendicular bisector we require compass, ruler and a pencil.
