Answer:
Step-by-step explanation:
dy/dx = d/dx log root under x-1 / root under x+1
dy/dx = root under x+1 / root under x-1 * 1/(x+1)^2/3 * 1/root under x-1
dy/dx = (x+1)^2/ x-1
Step-by-step explanation:
The standard equation of a circle is 
Center = (h, k)
#1
Center = (0,2)
h = 0
k = 2
r = 5


#2
Center = (-4,-5)
h = -4
k = -5
r = 



#3
Center =(-1,3)
h = -1
k = 3
r = 8



#4
Center: (9,0)
h = 9
k = 0
r =
