KE = 0.5*m*v2
KE = (0.5) * (1000 kg) * (20 m/s)2
the answer is:
C. -23 + 6 = x
Step-by-step explanation:
- (-6) = + 6
x² + y² – 10x + 6y + 18 = 0
x² – 10x + y² + 6y + 18 = 0
x² – 10x + 25 - 25 + y² + 6y + 9 - 9 + 18 = 0
(x-5)² + (y+3)² -16 = 0
(x-5)² + (y+3)² = 16
(x-5)² + (y+3)² = 4²
Center at (5,-3) radius = 4
Part 2
1. Complete the square for x and y
2. Put in the format for a circle. (x-h)² + (y-k)² = r², center at (h,k) with radius = r
