Answer:
The equation of parabola in vertex form is 
Step-by-step explanation:
Given coordinate of vertex is
and the parabola passes through the point 
So, the equation of parabola in vertex form is

Where
is the coordinate of the vertex.

Plugging these value in equation we get,

Now, we will find the value of 
Plug the coordinate 


Plug the value of
in the equation 
So, the equation of parabola with vertex
and passes through the point
is
≅
I feel like the answer is D, because
is greater than 397.9 and less than 402.1.
1) 4x + 12x² + 9 + 3y + 2x + 11y
6x + 12x² + 14y + 9
2) x² + 2y + 15x² + 4x + 21
4x + 16x² + 2y + 21
3) 8x + 12 + 17y + 3x + y + 8
11x + 18y + 20
Hope this helps :)
Answer: 5/8
Step-by-step explanation: Its cut into 8 slices and you give 3 away so you do 8-3=5 and that means it would be 5/8.
