Step-by-step explanation:
Given that,
The diameter of the merry-go-round, d = 14 feet
Time taken, t = 6 seconds
Radius, r = 7 feet
The linear speed of the merry-go-round is given by :

Also,

Where
is the angular speed
So,

Hence, his linear and angular speeds are 7.33 m/s and 1.04 rad/s.
Answer: 4, 800
Step-by-step explanation:
Answer: -4
Step-by-step explanation:
Do -6 x 2 to get -12, then divide by 3 to get -4
Thats assuming this is a fraction and not an actual division sign
I believe the answer would be this:
-y^2 - 21
Simplifying that would be 3 * (-7) -10+25 = -6. Combining like terms will get us to -21 +15 = -6, going further will be -6 = -6. Remember Order of Operations. Since -6 = -6, the equation is true.
