Answer:
Adding that line at the end of a speech is an appeal to Pathos.
Explanation:
Pathos is a feature of rhetoric related to appealing to the emotional side of an audience that is listening to the speech. Pathos has the function of seeking public empathy for a cause and, therefore, uses words that generate a strong feeling in people about something.
In the line "it's politics of believing in things unseen; of believing in what this country might be; and of standing up for that belief and fighting for it when it's hard," we can see that the author of the speech is appealing to the patriotic feeling of people, causing the audience to be moved, about the need to fight for the country, even if it is difficult to obtain victory. For this reason, we can say that the author made an appeal to pathos, when he added this line to the speech.
Accountants only concern themselves with direct costs which involve things like the cost of materials, rent, and labor for instance. This profit is aptly named "accounting profit".
Economists consider those costs as well, but they also include indirect costs such as opportunity costs of other investments. Recall that opportunity cost is the cost of what you give up if you make a certain decision.
For instance, if a car factory makes 4 door sedans, but it could be making more money with SUVs, then the opportunity cost is high and the economic profit is lower compared to the accounting profit.
