Y=6x^2 -5x+6 ( the first option )
hay that no solution because the root is irrational... and this is my answer
The correct answer should be :
Option 3 : 
Hope this helps,
Davinia.
I would say that B) is the correct answer hope this helps!!
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.
