X2 + y2 -2x + 24y +120 = 0

Mathematics
1 answer:
Nadusha1986 [10]3 years ago
8 0

Answer:

r=5  O(1;-12)

Step-by-step explanation:

x² + y² -2x + 24y +120 = 0

⇒ x²-2x+1+ y²+ 24y+144-145+120 = 0

⇒ (x-1)²+ (y+12)²=25   and    (x-h)² + (y-k)² =r²

so, h=1          k=-12       <u>r=√25=5</u>

center is O(h;k)   <u>O(1;-12)</u>

Answer:

15.) BAD = 10. (Since AC is 8 and CD is 2 you'll add em together to form a right angle, and BAD is a right angle so therefore they are the same.)

16.) AB = 2. (CD is 2 so therefore AB is 2, Again same size...)

17.) BD = 8. (Same size as AC...)
