The circle has radius 6 feet, so its total circumference is 2<em>π</em> • (6 ft) = 12<em>π</em> ft.
As an arc, the complete circle corresponds to a central angle of 2<em>π</em> radians. So the red arc corresponds to a central angle <em>θ</em> such that
<em>θ</em> / (15 ft) = (2<em>π</em> rad) / (12<em>π</em> ft)
Then
<em>θ</em> = (15 ft) • (2<em>π</em> rad) / (12<em>π</em> ft) = 15/6 rad = 2.5 rad
T=k/s
So k/36 = 2
k = 72
Put into original equation
t= 72/3 (s is 3)
So t is 24
Answer:
In fact, they'll do that if only ONE of them is out of tune.
As long as there's a difference between the two frequencies,
they'll create beats.

Answer:
-36
Step-by-step explanation:
replace x with -5 and solve for the parenthesis and then take that number which would be -16 and multiply it by 9 which then would give you -144. So then you would take -144 and divide it by 4 and your answer would be -36.
