Answer:
5
Step-by-step explanation:
The amplitude is the coefficient of the cosine function: 5.
U got to divide 78 and 12 then
Answer:
Step-by-step explanation:
we have
solve for x
eliminate the parenthesis (apply the distributive property)
---> correct representation of the inequality
Adds (5x-15) both sides
Multiply by -1 both sides
The angular velocity by definition is given by:
w = rev / t
Where:
rev: revolutions
t: time
Substituting values we have:
w = (6 * (2 * pi)) / (12)
w = 3.141592654 rad / s
Answer:
the average angular velocity of the spinner, in radians per second, for the 12-second interval is:
w = 3.141592654 rad / s
