<span>First find the central angle A in degree.
Perimeter circle 2Pi*R --> 360 deg
Arc A = 14.13 --> x deg
(360*14.13)/2Pi*R = 5086.8/37.68 = 135 deg
The pendulum rotates 135 deg in 3 sec. Then, the angular velocity is : 135/3 = 45 deg/sec.
Hope this helps!

Answer: 2 or more.
X and Y could be anything, so there are at least two answers
Multiples of 8 through 60 are 8, 16, 24, 32, 40, 48 and 56
No. of favorable outcomes= 7
Thus, P(E)=7/60
Combine like terms the variables first. 4b-15b=-11b
-7+3=-4
-11b-4
