For twelve jerseys it would be $210
The equation of a parabola is:

If a>0, then the parabola opens up;
If a<0, then the parabola opens down.
The coordinates of focus are:
Answer:
(2, 2 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
[
(x₁ + x₂ ) ,
(y₁ + y₂ ) ]
Here (x₁, y₁ ) = (A(5, 8) and (x₂, y₂ ) = B(- 1, - 4) , thus
midpoint = [
(5 - 1),
(8 - 4 ) ] = (2, 2 )
