The sum of the first ten terms of an arithmetic
Progression is 400. If the sum of the first 6
terms of the same series is 120, find the 15th term.​

Answers

Answer 1

Answer:

345.

Explanation:

Sum of n terms = n/2[2a1 + (n-1)d]

So 400 = 10/2(2a1 + 9d) and

120 = 3(2a1 + 5d)  so we have the system:

400 = 10a1 + 45d ......... A

120  = 6a1 + 15d    ..........B         multiply this by 3:

360  = 18a1 + 45D     Subtract this from equation A:

40 = -8a1

a1 = -5

So plugging this value into B:

d =  (120 - 6*-5) / / 6

= 150/6 = 25.

15th term = a1 + (n - 1)d

= -5 + (15-1)25

=  345.

When you give the authors or editors' names in a works cited citation, which of the following things do you need to include?
A. Tides, such as Dr., Mr., and Sir
B. Degrees, such as PhD, MD, and DDS
C. Suffixes, such as Jr. and Ill
D. Full middle names​

Answers

Answer:

C. Suffixes, such as Jr. and Ill.

Explanation:

When citing the names of authors or editors on any works cited page, it is mandatory to include the full details of the author. This includes the suffixes such as "Jr." or "III" as they are a part of the whole name of the author or editor.

While the inclusion of titles such as "Dr. Mr./Mrs. Sir" is not necessary, or even their degrees, it is mandatory to include the suffixes. Middle names are taken in initials and need not be written in full.

Thus, the correct answer is option C.

The author is using satire in this excerpt to emphasize the

A. utter absurdity of his plan.

B. necessity for warm winter clothing.

C. ways that people are cruel to children.

D. various benefits of his plan.

Answer:

A. utter absurdity of his plan.

Explanation:

From the book"A Modest Proposal", the writer is using satire to show how utterly absurd the idea of selling of one's children to be eaten as a solution to the extreme hunger in Ireland.

The author uses satire to show how absurd it is to sell off one's children because of poverty.

The centeral theme of the novel is to reduce population growth by selling babies as food. The wealthy, according to Swift, buy the poor's infants and serve them as a delicacy.

Correct option is A.

His ludicrous notion, in the modest plan, is to sell your children to be devoured; a remedy that will help Ireland's poverty. Although it's all parody and he does not intend to go down that path, he is basically suggesting that the wealthy are the only ones who can commit such heinous acts since they have the financial resources to do so.

His family had migrated from Dhaka, Bangla Desh to India in 1971 with the hope of finding better life conditions. Every morning he roamed about streets collecting garbage. Many other boys also accompanied him. His family lived in miserable conditions. He could not afford to go to school. He did not have even a pair of slippers to wear. He wished to play lawn tennis which was beyond his reach. He also found a job at a tea-stall where he ran various errands for the tea-stall owner.

Their evil nexus did not let them be free. Approximately 20,000 children worked in the glass furnaces with high temperatures, in dingy cells without air and light, often losing the brightness of their eyes. Thus the angle-makers of Firozabad lived in a state of perpetual poverty and exploitation.

Read the paragraph.
When people adopt pets, they often choose a puppy or a kitten. But people should give more serious consideration to adopting an older animal. Older animals make loyal pets, and they often require much less training. According to the National Humane Society, older pets are already house trained, they are less likely to destroy items within the home, and many of them know basic commands. Veterinarian Dr. Maria Hendricks agrees. "Older pets often make better companions than younger ones," she said, "because they are often much more calm and obedient." So the next time you visit the pet shelter looking for a new member of your family, think seriously about adopting an older animal. It just might be the perfect pet.
