Given:
radius of the pendulum = 6 feet
arc length = 14.13 feet
time = 3 seconds
Required:
What is the angular velocity?
Solution:
To compute for the angular velocity, we can use the formula:
w = s/rt
where,
w is the angular velocity
s is the length of the arc
r is the radius of a circle or pendulum
t is the time
substituting the values,
w = 14.13 feet / 6 feet × 3 seconds
w = 0.785 per seconds
The first answer is x=63
the second one is x=10
The number of way we can choose 2 males out of 8 is combinations of:
C(8,2)=7*8/2 =56/(1*2)=28
to choose 3 females out of 6
C(6,3)=6*5*4/(1*2*3)=120/6=20
the number of committees is= 28*20=560
Answer:
x = 3
Step-by-step explanation:
First, simplify by subtracting 2x from 6x:
6x - 2x + 8 = 20
4x + 8 = 20
Then, solve for x:
4x + 8 = 20
4x = 12
x = 3
So, the answer is x = 3
