We'll use the notation
for the principal value and
for all the values:

Part I


Part II. In our range we can write


Part III.

Part IV.


The angular velocity for this problem is given by:
Angular speed = 200 rev / min
The first thing you should keep in mind is the following conversion:
1 rev = 2π radians
Applying the conversion we have:
Angular speed = 200 * (2π)
Rewriting:
Angular speed = 200 * (2 * 3.14)
Angular speed = 1256 radians / minutes
Answer:
the angular speed is:
Angular speed = 1256 radians / minutes
Use the equation 459/x=85/100. then you cross multiply 459 and 100 to get 45900. after that you divide 45900 by 85 to get x=540
Answer:
We cannot solve without a value for x. The simplified form is 
Step-by-step explanation:
If the equation is
then we cannot solve it until we know the value of x. We can simplify it using order of operations such as PEMDAS.

Answer:
(7y-3x)2
Step-by-step explanation:
It's the same thing but backwards
