The true statement is B. <u>/ </u>R=<u>/ </u>X
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.

5(5a+b)-13
You would have to distribute
5*5a=25a
5*b=5b
Answer: D
A is just a survey (yes or no answers), B is more of a factual question (not concerning a set or population), and C is the same as B
