Answer:
- 8π radians/second
- 527.8 meters
Step-by-step explanation:
A) The angular velocity is the ratio of angular distance to time:
ω = 1 revolution / (0.25 s) = (2π radians)/(0.25 s)
ω = 8π radians/second
__
B) The arc length is ...
s = rθ = rωt
s = (35 cm)(8π rad/s)(60 s) = 16,800π cm
s ≈ 52779 cm = 527.79 m
The wheel travels about 527.8 meters in one minute.
A = number of $1 bill
B = number of $5 bill
A + B = 1919
A*$1 + B*$5 = 5959
so
A + B = 1919
A + 5B = 5959
Substract both equation
A + 5B - (A + B) = 5959 - 1919
4B = 4040
B = 1010
And
A = 1919 - B = 1919 - 1010 = 909
A = 909
Check the result :
A*$1 + B*$5 = 909 + 1010*5 = 909 + 5050 = 5959
Answer:
the slope is 0
Step-by-step explanation:
If 7 = -4, then the line will be horizontal on (-4) going on forever, never moving up or down. Therefore, there will be no slope.
Answer:
can you give me more details or is that all the quetion tells you
Step-by-step explanation:
√[(5-1)² + (5-5)²]
√[16+0]
√(16)
+4 or -4 units
I hope this helped :D
