The square of the distance between C(4, -5) and P(1, -2) is given by the Pythagorean theorem as
  (4-1)² +(-5-(-2))² = 18
This is the square of the radius of the circle, so we can use it for r² in the formula
  (x -h)² +(y -k)² = r² . . . . . . . circle of radius r and center (h, k)

Your circle has equation ...
  (x -4)² +(y +5)² = 18

HELP ASAP PLZZ
Nonamiya [84]

Answer:

The Answer is A. 2/5

Step-by-step explanation:

The way i Divide fractions is by if you take the second fraction and swap the numbers around, you can do 7/24 TIMES 48/35. then you multiply the numbers NOT in a crossway like 7 times 35 butin a straight way so its 7 times 48. Doing so will get you 336/840. I simplified this answer by 6 and got 56/140 then i simplified it again by 4 to get 14/35 and once more i simplified it by 7 to get 2/5.
