Answer:

An essay is, generally, a piece of writing that gives the author's own argument, but the definition is vague, overlapping with those of a letter, a paper, an article, a pamphlet, and a short story. Essays have traditionally been sub-classified as formal and informal. Formal essays are characterized by "serious purpose, dignity, logical organization, length," whereas the informal essay is characterized by "the personal element (self-revelation, individual tastes and experiences, confidential manner), humor, graceful style, rambling structure, unconventionality or novelty of theme," etc.[1]

Essays are commonly used as literary criticism, political manifestos, learned arguments, observations of daily life, recollections, and reflections of the author. Almost all modern essays are written in prose, but works in verse have been dubbed essays (e.g., Alexander Pope's An Essay on Criticism and An Essay on Man). While brevity usually defines an essay, voluminous works like John Locke's An Essay Concerning Human Understanding and Thomas Malthus's An Essay on the Principle of Population are counterexamples.

In some countries (e.g., the United States and Canada), essays have become a major part of formal education. Secondary students are taught structured essay formats to improve their writing skills; admission essays are often used by universities in selecting applicants, and in the humanities and social sciences essays are often used as a way of assessing the performance of students during final exams.

The concept of an "essay" has been extended to other media beyond writing. A film essay is a movie that often incorporates documentary filmmaking styles and focuses more on the evolution of a theme or idea. A photographic essay covers a topic with a linked series of photographs that may have accompanying text or captions.

Step-by-step explanation:

2.) $230 x 28% = $64.40

$230 - $64.40 = $165.60 sales price

3.) $45,000 × 25% = $11,250

$45,000 - $11,250 = $33, 750 discount price

$45,000 + $11,250 = $56,250 mark up price

$56,250 - $33,750 = $22,500 answer

4.) $33,750 x 8.875% = $2995.31

$33,750 + $2995.31 = $36,745.31 with tax

5.) $56,250 x 8.875% = $4,992.19

$56,250 + $4,992.19 = $61,242.19 with tax

6.) $33,750 x 6% = $2,025.00 Tom's commision

6. Jill made a quilt for her new sister. The quilt is square with an area of 36 square feet. What
VMariaS [17]

The area for the square is given, and it is 36. To simply find the length of each side, all you have to do is take the area and square root it. The square root of 36 ( ask yourself what number times itself is equal to 36? To get your answer or input it in the calculator. ) is 6. So, the answer is 6 and each side of the quilt is a length of 6.

Find the distance from A(-8,-3,-2) and B(-4,8,0) , find ||AB||
RUDIKE [14]

Answer:

||AB|| = 11.8743

Step-by-step explanation:

Distance between two points:

Suppose that we have two points, (x_1,y_1,z_1) and (x_2,y_2,z_2). The distance between them is given by:

D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2+(z_2-z_1)^2}

Distance from A(-8,-3,-2) and B(-4,8,0)

||AB|| = \sqrt{(-4-(-8))^2+(8-(-3))^2+(0-(-2))^2}

||AB|| = \sqrt{4^2 + 11^2 + 2^2}

||AB|| = 11.8743
