CosΘ < 0 ->2nd or 3rd quadrant
cotΘ > 0 -> 1/tanΘ > 0 -> tanΘ >0 -> 1st and 3rd quadrant.
So Θ lines in the 3rd quadrant
62 numbers are divisible by 100 into a whole number
A) Linear velocity, v = ωr ω = Angular velocity, r = radius.
<span>ω = 5 revolutions per minute. 1 minute = (1/60) hour. </span>
<span>= 5*2π radians / (1/60) hour = 600π radians per hour π = 3.14 </span>
= 600*3.14 = 1884 radians / hour
<span>but radius, r = 10 feet, 5280 feet = 1 mile, 10 feet = (10/5280) mile </span>
Linear velocity, v = ωr
<span> v = 1884 radians / hour * (10/5280) mile </span>
v ≈ 3.568 miles / hour<span />
The expression would be j / 9. J is a variable.
