The disk spins at a constant number of revolutions per second. This means, the angular velocity is constant.

We know that,

Linear velocity = r x Angular Velocity
where r is the radius.

So, for a given angular velocity, larger value of r will have larger Linear velocity. Since the value of r at point B is more than at point A, the value of Linear velocity will be more at point B.

So, the correct answer is option C

ruslelena [56]

Answer:

Step-by-step explanation:

Sin:

-3 = −0.14112

-4 = 0.756802

Together (−0.656987)

Cos:

-3 = −0.989992

-4 = −0.653644

Together(0.753902)

Tan:

-3 = 0.142547

-4 = -1.157821

Your fixed expenses are $1235.78/month. You want to save 5 months worth for an emergency fund over time. How much must you save

juin [17]

Answer:

$514.908 or $514.91

Step-by-step explanation:

First off we need to consider the amount of months in a year. There are a total of 12 months in a year. Now that we have the number of months in a year, we can now determine how much you need to save each month by using the Unitary Method.

First we take the number of months we want to save for and divide that to the total number of months in the year.

$\dfrac{5}{12}$

We then multiply that to the current amount of expenses we have per month.

× $\dfrac{5}{12}$ $* 1235.78$

= $514.908 or $514.91

So in conclusion you need to save $514.91 each month.
