He ran .45 miles per minute
Answer:
C.
(0.525, 0.635)
Step-by-step explanation:
0.58 +/- 0.994sqrt(0.58×0.42/80)
0.58 +/- 0.05485042953
[0.5251495705 , 0.6348504295]
9^5 is 45
As, 9+9+9+9+9 =45
Answer:

Step-by-step explanation:
For the spring mass system
my"+by'+ky=0
The system is said to be critically damped if 
Here b is coefficient of friction
m is the mass of system
And k is spring constant
We have given m = 2 kg , k =1
So 


So the coefficient of friction is
The answer is B The final balance is $1685.13
