The thing that should be fine regarding the algebra is A. They must first check that the operation * is closed for all a and b in S, meaning that when they perform the operation on any two elements in S, the result is also in S.
What should they do first?They will need to check that the operation * is closed, associative, has an identity element, and that every element has an inverse in order to determine if the set S with operation * forms a group.
They can check each of these conditions by working through examples and verifying that they hold for all elements in S. If the set S with operation * satisfies all of these conditions, then it is a group. If it does not satisfy one or more of these conditions, then it is not a group.

Explanation:
Read the description of 1844 Manchester England and write a short advertisement for a real estate company that might encourage people to move or work there.
Answer:
Advertising is any paid form of communication from an identified sponsor or source that draws attention to ideas, goods, services or the sponsor itself. Most advertising is directed toward groups rather than individuals, and advertising is usually delivered through media such as television, radio, newspapers and, increasingly, the Internet. Ads are often measured in impressions (the number of times a consumer is exposed to an advertisement).
Advertising is a very old form of promotion with roots that go back even to ancient times. In recent decades, the practices of advertising have changed enormously as new technology and media have allowed consumers to bypass traditional advertising venues. From the invention of the remote control, which allows people to ignore advertising on TV without leaving the couch, to recording devices that let people watch TV programs but skip the ads, conventional advertising is on the wane. Across the board, television viewership has fragmented, and ratings have fallen.
Print media are also in decline, with fewer people subscribing to newspapers and other print media and more people favoring digital sources for news and entertainment. Newspaper advertising revenue has declined steadily since 2000.[1] Advertising revenue in television is also soft, and it is split across a growing number of broadcast and cable networks. Clearly companies need to move beyond traditional advertising channels to reach consumers. Digital media outlets have happily stepped in to fill this gap. Despite this changing landscape, for many companies advertising remains at the forefront of how they deliver the proper message to customers and prospective customers.
The Purpose of Advertising
Advertising has three primary objectives: to inform, to persuade, and to remind.
Informative Advertising creates awareness of brands, products, services, and ideas. It announces new products and programs and can educate people about the attributes and benefits of new or established products.
Persuasive Advertising tries to convince customers that a company’s services or products are the best, and it works to alter perceptions and enhance the image of a company or product. Its goal is to influence consumers to take action and switch brands, try a new product, or remain loyal to a current brand.
Reminder Advertising reminds people about the need for a product or service, or the features and benefits it will provide when they purchase promptly.

Which of the following pairs of angles is not necessarily congruent
Answer:
E. [tex]\angle 3[/tex] and [tex]\angle 5[/tex].
Explanation:
According to the figure, we have the following conclusions:
1) [tex]\angle 1[/tex] and [tex]\angle 2[/tex] are vertical opposite angles. ([tex]m \angle 1 = m \angle 2[/tex])
2) [tex]\angle 2[/tex] and [tex]\angle 3[/tex] are internal alternate angles. ([tex]m \angle 2 = m\angle 3[/tex])
3) [tex]\angle 2[/tex] and [tex]\angle 4[/tex] are corresponding angles. ([tex]m\angle 2 = m\angle 4[/tex])
4) [tex]\angle 3[/tex] and [tex]\angle 4[/tex] are vertical opposite angles. ([tex]m \angle 3 = m \angle 4[/tex])
But, [tex]\angle 3[/tex] and [tex]\angle 5[/tex], since [tex]m \angle 3 + m\angle 6 + m\angle 5 = 180^{\circ}[/tex], where [tex]\angle 3[/tex] is an acute angle and [tex]\angle 6[/tex] is a right angle, and [tex]m \angle 4 + m \angle 5 = 90^{\circ}[/tex]. Then,
[tex]m\angle 5 = 90^{\circ} -m\angle 4[/tex].
[tex]m\angle 5 = 90^{\circ}-m\angle 3[/tex]
Hence, the right answer is E.

Jorge's production possibilities schedule demonstrates that
A. Green beans have a trade-off with corn, but corn does not have a trade-off with green beans
B. Green beans do not have a trade-off with corn, but corn has a trade-off with green beans
C. There is no trade-off between corn and green beans
D. Both corn and green beans require a trade-off
Answer: D. Both corn and green beans require a trade-off
Explanation:
Trade off simply means that for one to gain or have an increase with regards to a particular thing, thus will lead to the decrease or reduction in something else.
We should also note that the production possibility curve shows how two goods which are green beans and corn in this case can be efficiently used while making use of the resources that are made available for that particular economy.
In this case, we can see that as the pounds of green bean increase, the pound of corn reduces. This shows that both corn and green beans require a trade-off

What issues may arise if nominal gross domestic product was used instead of real gross domestic product?
Answer: See explanation
Explanation:
Real gross domestic product is simply refered to the economic output of a particular country which has been adjusted for price changes as inflation was taken into consideration.
Nominal gross domestic product is the measurement of the gross domestic product of a particular country which makes use of current prices, and isn't inflation adjusted.
The issue that may arise when nominal gross domestic product was used instead of real gross domestic product is that the nominal GDP leads to the inflation of the growth figure in the economy. This is because the nominal GDP doesn't take inflation into effect.
This leads to the misleading of the GDP since there'll be an overstatement of the GDP even though it was actually a rise in the inflation rate for the particular economy.
