Answer:
I think that is quadratic
The vertex of the parabola is between the shortest line connecting its focus and directrix, so between (0, -4) and y = 4 is the point (0, 0), which is the vertex of the parabola. Also, this parabola faces downward.
The general formula for a parabola that faces downward is y = -4cx^2, where c is the distance from the vertex to either to focus or the parabola. Since c = 4, the equation is y = -16x^2, which is choice A.
Answer:
Perpendicular
Step-by-step explanation:
m=y2-y1/x2-x1
m=15-3/14-(-2)
m=3/4
1/7 x 9/4 = 9/28
This process to solving division involving fractions is called “keep, change, flip”
The center of the circle is (5,3)
