We know that
<span>The angular velocity is 10π rad/sec
step 1
convert to rad/min
1 min-----60 sec
X min----> 1 sec
X=1/60 min
V=</span>10π rad/(1/60)------> V=600 π rad/min
the answer is the option
<span>D)The angular velocity is 600π rad/min.</span>
Cosine 65 = 12 / x
0.4226183 = 12 / x
x = 12 / 0.4226183
<span>
<span>
<span>
x = 28.39441</span></span></span>
So, I'd say you are correct.
So this is what i did but im not sure if its 100% correct
585 / 9 to get the number of groups = 65
then you take 65 x 3 for number of students in each group and you get the final answer of 195 students

As we know, slope (m) is equal to tan θ for a straight line :


So, we can say that it's a positive constant slope
Answer:
B
Step-by-step explanation:
x/5 + 2/3x
first you multiply both denominator.
this will be you denominator unless you can simplify it.
denominator=5 x 3X = 15X
now you times both denominator with the opposite numerator.
e.g. 5 x 2 and X x 3X.
=10 and 3X^2
now you and both numerators which is 3X^2 + 10
so the answer is b
