Answer: (y-3)^2= 52(x+7)
The focus is (-10, -7) and the directrix is x=16. The y-coordinate of the vertex should be same as the focus(k=-7). Then the x-coordinate of the vertex would be:
p + (-10)= 16 - p
2p= 16 + 10
p=26/2= 13
The x-coordinate of the vertex would be:
h= p+ (-10)
h= 13 - 10= 3
The vertex coordinate would be: (h, k)= (3, -7)
For a vertex (h, k), the formula for equation would be
(y-k)^2=4 p(x-h)
(y-3)^2= 4*13(x--7)
(y-3)^2= 52(x+7)
The answer is 2745
so 5x1= 5 5x6=30 so that is 305
4x1=4 4x6=24 so that is 2440
and 305+2440 = 2745
A. It falls to the left and falls to the right and has an axis symmetry at x= -5
Im guessing A. But I would be wrong.
The range is just the distance between the biggest number
and the smallest one.
The biggest number on that list is 350 .
The smallest number on that list is 75 .
The range is from 75 to 350, or a distance of 275 .
