If a wind turbine makes 76 full revolutions every 1 minute what is it’s angular speed?
Maslowich

Answer: 7.958 \frac{rad}{s}

Step-by-step explanation:

We are told the wind turbine makes 76 revolutions in 1 minute. This means the angular speed \omega of the object in revolutions per minute (rpm) is:

\omega=76 rpm=76 \frac{rev}{min} (1)

However, we have to convert this to \frac{rad}{s}, since this is the unit used in the International Systme of Units for angular speed.

So, we can do this knowing that:

\omega=\frac{2 \pi}{T}  (2)

Where:

2 \pi=360\° is the value of one revolution

T=1 min=60 s is the period of rotation

With this information in mind, let's make the conversion:

\omega=76 \frac{rev}{min}. \frac{1 min}{60 s}. \frac{2 \pi}{1 rev} (3)

\omega=7.958 \frac{rad}{s} (4) This is the wind turbine angular speed

How do you round 65.0798 to the nearest tenth
Dmitry_Shevchenko [17]
65.0798 rounded to the nearest tenth is 65.1, if the number after the number you are rounding is 5 or over you will round up. If the number after it is under 5 then it will stay the same.

Please help me!! will give you brainliest!!!

1. ( -1,2) is the same as (x=-1, y=2)
Substitute in your equation
y=3x-2
2=3•(-1)-2
2=-5 this is NOT true so (-1,2) is not a solution for the equation y=3x-2

2. (0,-2)
9x-6=3y
9(0)-6=3•(-2)
-6=-6 this is true so ( 0, -2) is a solution for the given equation
