circle:
x2+ y2 = 2
parabola:
y = 2x2 – 3
The standard form of equation of circle is:
( x – h )^2 + ( y – k )^2 = r^2
We are given the equation x^2 + y^2 = 2.
Where h and k are the x and y coordinates of the center.
Basing on the standard equation, the center is at (0 , 0) and r = 
The standard form of equation of parabola with the axis of
symmetry parallel to the y-axis is:
(x - h)^2 = 4p (y - k)
Rearranging the given equation into this form:
x^2 = (½) y + 3/2
x^2 = ½ (y + 3)
Since 4p is positive value, therefore the
parabola is opening up. The vertex is located at (0 , -3).

Answer: circle with its
center at (0, 0) and a radius of </span>
; parabola opening up with its vertex
at (0, –3)
Hey!
So what I did was I divided 42.84 by 6.12 to see that the answer is 7 and that is an answer choice.
But you should keep checking.
299.88 / 42.84 = 7
2099.16/299.88 = 7
There is a common ratio and it is 7
A is the answer!
Hope this helps!
