Determine if the relation is a function.
The relation is not a function.
Answer:
44/15 or maybe 2 14/15
Step-by-step explanation:
Old coordinate
As center of dilation is origin the scale factor only multiplied with B
So
new coordinate

- 1/2(2,-6)
- (2/2,-6/2)
- (1,-3)
Answer: 3,140 radians per minute.
Step-by-step explanation:
We know that the wheel does 500 revolutions per minute.
This is called the frequency of the wheel, and this is written as:
f = 500 rev/min = 500 RPM
The angular speed (or Angular velocity) is written as
ω = 2*pi*f
And this quantity is in radians/unit of time.
where pi = 3.14
then:
ω = 2*3.14*500 (rev/min)*(rad/rev) = 3,140 rad/min
This means that the angular velocity (or angular speed) is 3,140 radians per minute.
