From the diagram, Vertex =(2,3)
So, (h,k)=(2,3)
So, h=2 and k=3
The equation of parabola is
p is the distance of directrix or focus from vertex.
As directrix is
y=8=k-p=3-p
So, 8=3-p
Let, us subtract 3 from both sides, we get
8-3=3-3-p
5=-p
or p=-5
So, h=2,k=3 and p=-5
So, the equation of parabola is
=4(-5)(y-3)
Equation of graph is
(x-2)^2=-20(y-3)
Answer: the last one, 31.6
Answer:
225/4
Step-by-step explanation:
x^2+15x+c
take half of 15 and square it
(15/2)^2
225/4
We can use a rule of three to solve the exercise.
Therefore, there were 161 robberies in Springfield in 2012.
