Consider the demand curve for a good is given by: =500−2 and suppose that the good’s price is $100.
a) Calculate the quantity demanded for the given price.
b) Calculate the price elasticity of demand if the price of good decreases from $100 to $90.

Answers

Answer 1

Taking into account the demand curve and the definition of price elasticity of demand:

a) the quantity demanded is 300 for the given price.

b) the price elasticity of demand if the price of good decreases from $100 to $90 is -0.5625.

Consider the demand curve for a good is given by: Demand=500−2×P and suppose that the good’s price is $100.

a) Considering that the demand curve represents all the quantities of a good or service that buyers would be willing and could buy at all possible prices, to calculate the quantity demanded for the given price you should replace the price P with $ 100:

Demand=500−2×$100

Solving:

Demand=500− 200

Demand= 300

Finally, the quantity demanded is 300 for the given price.

b) The price elasticity of demand indicates how much the quantity demanded of a good changes when its price changes. It is defined as the percentage change in quantity demanded divided by the percentage change in price.

Then the price elasticity of demand can be expressed as:

E= (ΔQ÷Q) ÷ (ΔP÷P)

In this case, you first calculate the change in the quantities.

To do this, the change in the quantities  is obtained by subtracting from the final demand to the initial demand, the final quantity being 500- 2×90= 320 and the initial quantity 500 - 2×100= 300.

So the change in the quantities is: ΔQ= 320 - 300= 20

And the initial quantity Q= 320

On the other side, the price change is obtained by subtracting the final price from the initial price. This is ΔP= 90 - 100= -10

And the initial price P = 90

Replacing in the definition of price elasticity of demand:

E= (20÷320) ÷ [(-10)÷90]

Solving=

E= -0.5625

Finally, the price elasticity of demand if the price of good decreases from $100 to $90 is -0.5625.

Explanation:

Mrs. Nelson is a 5th grade teacher at Xander Elementary School. Mrs. Nelson is very tech-savvy and uses many forms of social media to communicate with her parents and students. At the beginning of the year, she asks parents to follow her on a communication app, Remind, so that they can receive important text reminders about upcoming events. Remind is typically used for group communication, for example, Mrs. Nelson might send out a reminder to the class that they have a field trip and will need to remember their lunches. After receiving a group text, parents then have the option to respond individually to Mrs. Nelson and they can then carry on a conversation in a private environment if they need to discuss more student-specific information.
Many of her students have their own cell-phones and have also begun following Mrs. Nelson the Remind app, and while does not encourage this, she doesn’t remove them when they do. It has never been an issue in the past, and she assumes it might help them to know what is going with upcoming and important events too.
Mrs. Nelson is a very loved and respected teacher, and she is known for providing a very safe and nurturing environment in her classroom. Whenever a student is struggling with anything, they always know that Mrs. Nelson will listen and support them. Because of the precarious nature of 5th grade, students often come to Mrs. Nelson with all kinds of problems. After sending out a Remind text about the upcoming early dismissal day, a student, Maddie, responded with a private message to Mrs. Nelson telling her that she needed to talk to her about a problem. Mrs. Nelson tells her to come to her first thing in the morning, so they can talk before class begins. The next morning, Maddie shows up early to class as instructed, and tells Mrs. Nelson that she thinks something is wrong with her because she doesn’t like boys the way her friends do, and but she really doesn’t want to be gay. She is afraid of what her parents and friends would say if she never likes boys the way she thinks she is supposed to. Though she was a little taken aback by this confession, Mrs. Nelson assures her that she will be ok, and that it is ok that she doesn’t have the answers to those questions right now. Thinking about it later that evening, Mrs. Nelson, was concerned that she hadn’t been supportive enough in talking with Maddie, so she sends her a private Remind text saying, "I want you to know that you are a very smart and beautiful young lady, and if you like boys or girls, that won’t change. I won’t say anything to anyone about our conversation."
Questions:
1. Identify the behaviors (if any) that you believe violate standards in the Educator Code of Ethics?
2. Which standards do you think were violated, explain your reasoning. If you feel that no standards were violated, explain your reasoning?
3. Should Mrs. Nelson have handled this situation differently so as not to violate the Code of Ethics, or (if you feel that there was no violation) to avoid her actions being called into question?

Answers

Answer:

that is nelsom is a 5th grade teahcer begining of year

Explanation:

1. Mrs. Nelson's behaviors: having a social media platform for interacting with parents, allowing her students to use their cell phones, supporting Maddie, and her assurance to Maddie that she was free to love boys or girls, do not violate the Educator Code of Ethics.

2. As a diligent teacher, complying with the Educator Code of Ethics, Mrs. Nelson has not violated any standards by her behaviors and relationships with her students and their parents.  The conclusion is because her behaviors and examples are worthy of emulation by other teachers. Teachers should be tech-savvy and ensuring regular communication with parents and students is essential in maintaining good teacher-parents-students relationships.

3. Mrs. Nelson handled this situation well, and she did not violate the Educator Code of Ethics.  The code requires ethical and professional responsibility towards students and their parents, without conferring undue advantage to any student based on gender orientation or other considerations.

Thus, Mrs. Nelson is acting ethically and in compliance with the Educator Code of Ethics.

Any firm that sells products or offers services to residents of the area is regarded as a local business. A local business, as expressed by the phrase "brick and mortar," might be a locally owned company or a large corporation with numerous sites operating in a particular region.

A local business could be a small shop, a food truck, or an office building. Because the local business owner owns the building where it is located, it differs from a chain store in another way. The majority of local businesses are often modest, family-run enterprises.

By making local purchases, you not only support your neighborhood's economy but also contribute to job growth. Your friends, family, or neighbours could be hired for these positions.

Explica tres razones sobre el problema de acceso a la infraestructura vial de Lima

Answers

Los problemas de la infraestructura de la ciudad de Lima son los trancones, huecos en las carreteras y la falta de oferta de servicios públicos de transporte.

Los trancones son problemas de transporte e infraestructura vial en la mayoría de las grandes ciudades del mundo debido a la gran cantidad de personas que viven en ellas y poseen un medio de transporte como un auto o una motocicleta. Adicionalmente los servicios de transporte públicos llenan la infraestructura causando trancones.

La gran cantidad de tráfico causa que la infraestructura vial se deteriore y se generen grandes huecos o grietas en ella. Los daños en la infraestructura vial hacen que los carros no puedan andar fluidamente y deban para para esquivar los huecos y las grietas.

Por último, la falta de oferta de servicios públicos hace que los pocos buses que hay anden llenos y la gente deba adquirir carros y motocicletas que a la final contribuyen al deterioro de la infraestructura vial.

C. It renders the maintenance of a normal circadian cycle difficult.
D. It carries a much higher risk of leading to substance abuse.

Answers

D. it carries a much higher risk of leading to substance abuse

The correct option is D. It carries a much higher risk of leading to substance abuse which is out of the following statement about rotating shift work is false.

Rotating shifts, according to the authors' hypothesis, made it harder for employees to maintain a normal sleep-wake cycle, which adversely impacted the quality of their sleep and might have weakened their ability to resist insulin.

How do you do a rotating shift schedule?

Each crew begins the rotation by working four nights in a row, then takes three days off in a row, before working three-day shifts and finishing the rotation by working four nights. Before the cycle is completed, the fourth week offers seven full days off.

The length of sleep when working shifts, especially a night shift, is least adversely affected by slowly rotating shifts. Permanent night shifts, however, can be an alternate shift-work pattern in operational situations when numerous personnel is needed at night.

Thus, D is the right answer. The following assertion concerning rotating shift work is untrue since it carries a significantly increased risk of developing into substance misuse.
