natta225 [31]

Answer:

c. 52 rad/s

Step-by-step explanation:

Final question does not correspond with available option. The real question is: <em>What is the angular speed in radians per second?</em>

At first we assume that spin balance rotates at constant rate and convert given angular speed, measured in revolutions per minute, into radians per second:

$\omega = \left(500\,\frac{rev}{min} \right)\cdot \left(2\pi\,\frac{rad}{rev} \right)\cdot \left(\frac{1}{60}\,\frac{min}{sec} \right)$

$\omega \approx 52.360\,\frac{rad}{s}$

Which corresponds to option C.

7z - 1/2 = 3z - 2

Subtract 3z to both sides:

4z - 1/2 = -2

Add 1/2 to both sides:

4z = -1 1/2

Divide 4 to both sides:

z = -0.375 or -3/8
