What is the angular velocity of a 6-foot pendulum that takes 3 seconds to complete an arc of 14.13 feet? Use 3.14 for pi

Answers

Answer 1
Angular velocity refers to the rate of change of angular displacement of a particle in a given time. The value of angular velocity specifies the rotational speed with which an object is travelling on its axis.
Mathematically, angular velocity, W = D/T,
Where D is the change in angular displacement and T is the time taken. 
From the question given, 
T = 3 second
The arc of the circle is 14.13 feet
The diameter of the circle is 12 foot.
The circumference of the circle is diameter * Pi = 12 * 3.14 = 37.7 feet.
14.13/37.7 = 0.3748
0.3748 * 360 degree = 134.93
134.93/3 = 45
Thus, the angular velocity is 45 degree/second.

You earn $10.00 per hour babysitting. Your total earnings depend on the number of hours you spend babysitting.

Answers

Final answer:

Susan's total income remains $16,000 regardless of the number of hours she works, up to the point where her earnings from work alone would exceed her government benefits. This design of the assistance program potentially reduces her incentive to work more hours. Opportunity costs must also be factored in, which can further influence her decisions.

Explanation:

Creating Susan's Income Table

Susan has the option to work up to 1,800 hours a year at $8 per hour. If Susan does not earn any income, she is entitled to $16,000 in government benefits. However, for every dollar she earns, her government support reduces by the same amount. To understand Susan's situation better, we can create a table showing various scenarios.

Let's assume Susan decides to work 500 hours in a year:

If Susan works more, her earnings increase but her benefits decrease, keeping her total income stagnant at $16,000, until she surpasses the threshold of $16,000 in earnings. This suggests the assistance program may limit her incentive to work more hours as the additional work does not increase her total income. Moreover, Susan must consider opportunity costs, such as childcare expenses, that might further reduce her incentive to work additional hours.

The Impact of Government Assistance on Work Incentives

Opportunity costs play a crucial role in Susan's decision-making. If the costs of working (like paying for childcare) exceed the benefits of working additional hours, she might opt to work less or not at all. Therefore, assistance programs can impact individual's work choices by affecting the marginal benefit of working additional hours.

The longest side of an isosceles obtuse triangle measures 20 centimeters. The other two side lengths are congruent but unknown.

What is the greatest possible whole-number value of the congruent side lengths?

A.9 cm
B.10 cm
C.14 cm
D.15 cm

Answers

B.10 cm hopes this helps

Answer:

C. 14 cm

Step-by-step explanation:

According to the Triangle Inequality Theorem, the sum of any two sides of a triangle must be greater than the measure of the third side.

Given,

The longest side of an isosceles obtuse triangle measures 20 centimeters.

Let x be the measure of the other two congruent sides,

By the above property,

20 < x + x

20 < 2x

10 < x

Thus, the measure of congruent sides must be greater than 10 cm,

Now, In an isosceles obtuse triangle, the square of the longest side is greater than the sum of squares of the other two congruent sides.

[tex](20)^2>x^2+x^2[/tex]

[tex]400>2x^2[/tex]

[tex]200>x^2[/tex]

[tex]10\sqrt{2}>x[/tex]

Since, √2 = 1.41421356≈ 1.41

[tex]\implies x < 10\times 1.41\implies x < 14.1[/tex]

Hence, the greatest possible whole-number value of the congruent side lengths is 14.

Option C is correct.

The probability of the complement of an event is ____ less than the probability of the event itself.
A. Not enough information provided to answer the question.
B. Sometimes
C. Always
D. Never

Answers

Answer: Choice B) Sometimes

--------------------------------------------------------
--------------------------------------------------------

Explanation:

Consider two events A and B. Let's make these two events complementary. This means that either one or the other happens, but not both at the same time. By this definition, this means

P(A) + P(B) = 1

Now let's assign a probability to event A. Let's make 
P(A) = 0.3

That would mean...
P(A) + P(B) = 1
P(B) = 1 - P(A)
P(B) = 1 - 0.3
P(B) = 0.7

So event B is more likely. If event A is the original event, then event B as the complementary event has a higher probability. 

So this initially implies that the answer would be "Always"; however, we can easily flip things around. Let's say that 
P(A) = 0.7

That would lead to P(B) = 0.3. All I've done here is swap the roles of events A and B. Now event A is more likely with a higher probability.

So this means that the answer is "Sometimes". It depends on if the initial event's probability. If the initial event has a probability less than 0.5, then the answer is "yes the complementary event is more likely". If the initial event's probability is greater than 0.5 then the answer is "no, the complementary event is not more likely"

Answer:

Choice B) Sometimes

Answers

180 pounds is the answer to your question.

Hope this helps :)

The number of weeks will the boys weigh the same amount is 15 weeks and the weight is 180 lb.

Given,

Justin and Tyson are beginning an exercise program to train for football season.

Justin weighs 150 lb and hopes to gain 2 lb per week.

Tyson weighs 195 lb and hopes to lose 1 lb per week.

We need to find in how many weeks will the boys weigh the same amount If the plan works and the weight be.

How to compare two quantities?

If 3 miles = 2 hours

For 4 miles the number of hours is:

3 miles = 2 hours

4/3 x 3 miles = 4/3 x 2 hours

4 miles = 8/3 hours

We have,

Justin:

Justin weighs 150 lb and hopes to gain 2 lb per week.

Let the number of weeks be W.

We can write the weight of Justin after W weeks as:

150  + 2W _____(1)

Tyson :

Tyson weighs 195 lb and hopes to lose 1 lb per week.

Let the number of weeks be W.

We can write the weight of Tyson after W weeks as:

195 - 1W _____(2)

Now,

The number of weeks both weighs the same:

From (1) and (2)

150 +2W = 195 - 1W

2W + 1W = 195 - 150

3W = 45

W = 45/3

W = 15

We can see that,

From (1) and (2)

150  + 2W = 150 + 2 x 15 = 150 + 30 = 180

195 - 1W = 195 - 1 x 15 = 195 - 15 = 180

Thus the number of weeks will the boys weigh the same amount is 15 weeks and the weight is 180 lb.

Answers

In this problem the formula for average credit card debt is D=393t+5680 where t is years after 1995. To find the total average credit card debt in the year 2027, we must first find the difference in years between 2027 and 1995 to get our t value. To do this subtract 1995 from 2027: t= 2027 - 1995 = 32 years. Next, we plug in 32 for t into the equation and solve for D: D = (393)*(32) + 5680 = $18,256.

As an unenrolled tax preparer, Daryl is subject to:

Answers

I think there are missing details in this question. I'll just discuss what an unenrolled tax preparer is.

Unenrolled Tax Preparers are individuals who possess the minimum qualifications required to prepare federal taxes and are granted a Preparer Tax Identification Number (PTIN) but are not Certified Public Accountants (CPA), lawyers, or enrolled agents.

They are only limited to filing only certain types of tax returns and can only represent their client on the basic audit level before the IRS. 

In order for an unenrolled tax preparer to become an enrolled agent, he or she must do the following:
1) Pass a three-part examination before the IRS 
2) Undergo compliance check on their tax history
3) Complete 16 hours of continuing education every year to retain their status. 

The correct answer is:

The Rules of Practice under Circular 230.

Explanation:

An unenrolled return preparer is someone that is not an attorney, CPA, enrolled agent, enrolled retirement plan agent, or enrolled actuary, who prepares and signs a person's tax return as the paid preparer. They may also be someone who prepares a return but is not required to sign the return.

According to the IRS, unenrolled return preparers must comply with the rules of practice and conduct in order to exercise limited practice before the IRS.

There are two specific sets of rules that apply in Circular 230:

Duties and restrictions relating to practice (Subpart B of Cir. 230), and conduct considered to exhibit incompetence or disrepute (Subpart C, Section 10.51 of Cir. 230).

A pet store has 9 puppies and 48 kittens.
What is the ratio of kittens to puppies?

Answers

The ratio of kittens to puppies is 16:3.

To find the ratio of kittens to puppies, you divide the number of kittens by the number of puppies.

Ratio of kittens to puppies = Number of kittens / Number of puppies

Given:

Number of kittens = 48

Number of puppies = 9

So, the ratio of kittens to puppies is:

Ratio = 48 / 9

Simplifying:

Ratio = 16 / 3

Explain how you would find the sign of the quotient 32 divided by -2 divided by -16÷4

Answers

This may not be the best explanation but hopefully at the very least it'll guide you!
When you multiply or divide a negative by another negative, you get a positive. When it is a negative and a positive, it remains negative.
Assuming your question simplified into a equation (or number form? Been a while, haha!) is 32÷-2÷(-16÷4), it would end as a positive. Because you first divide the positive 32 by a negative 2, you get a negative. Because -16÷4 is in parenthesis, it is done because following the rest of the equation (P.E.M.D.A.S.!), it would be 32÷-2÷-4. Going from left to right, as you should, it results in a negative being divided by another negative, so you get a positive. 32÷-2÷(-16÷4) = 32÷-2÷-4 = -16÷-4 = 2!
