Step-by-step explanation:
<u>Expression on the board :</u>
<u>Expression by the student </u>:
<em><u> Expression 1 </u></em>:
The expression 1 is equivalent to the expression on the board. Because the coefficients of x and y are same on both.
<em><u>Expression 2 :</u></em>
<em><u /></em><em><u /></em>
The expression 2 is also equivalent to the expression on the board. Because the coefficients of x and y are the same.
For this case, the first thing we must do is to take into account the following transformation of units:
1 revolution = 2pi radians
1 minute = 60 seconds
Applying the transformation of units we have:
Answer:
To the nearest hundredth, the angular velocity of the drum is 78.54 radians per second.
