Math, microeconomics or criminal justice
foci (-5,7) and (1,7) vertices (-4,7) and (0,7) is a horizontal hyperbola
center is midpoint between the two foci = ((-5+1)/2, 7) =(-2,7)
c^2 =a^2 + b^2, a =-2+4= 2, c-2+5 =3
b^2 =c^2 -a^2 = 3^2 - 2^2 = 9-4=5
b^2 = 5
(x-h)^2/a^2 + (y-k)^2/b^2 = 1 (h,k) = (-2,7)
(x+2)^2/2^2 - (y-7)^2/(sqr5)^2 = 1
(x+2)^2/4 - (y-7)^2/5 = 1
