Answer
24/5
Step-by-step explanation:
Standard equation: (x-h)^2 + (y-k)^2 = r^2
Here, (0-[-6])^2 + (0-[-8])^2 = r^2
Find r: 36 + 64 = 100, so r = 10
Then the desired equation is (x+6)^2 + (y+8)^2 = 10^2
80km/h because km is more than miles
1s = 0.1s X 10
1 2/3 = 5/3
10 = 10/1
5/3 X 10/1 = 50/3 = 16 2/3 = 16.666m/s
