what are the coordinates of the center of the circle whose equation is (x – 9)2 + (y + 4)2 = 1?

(−9, 4)

(3, −2)

(9, −4)

(−3, 2)

x-9=0 => x=9

y+4=0 => y=-4

=> (9,-4)

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)

5.7622

step-by-step explanation:

the ten thousandths place is the 2. you round it up if, that number in whatever place is 5 or higher.
