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.

Dana is purchasing a new car that costs $24,650. Although Dana will be financing her car, she must pay sales tax, title, and tag
telo118 [61]

Dana must pay $1238.75 upfront.

Step-by-step explanation:

Given,

Cost of car = $24,650

Sales tax = 3.5%

Amount of sales tax = 3.5% of cost of car

Amount of sales tax = \frac{3.5}{100}*24650

Amount of sales tax = \frac{86275}{100}=\$862.75

Amount of title and tag fees = $376

Total upfront amount = Amount of sales tax + Amount of title and tag fees

Total upfront amount = 862.75+376 = $1238.75

Dana must pay $1238.75 upfront.
