the first term of A.P is 5 and the last term is 45 and the sum of all term is 400. find the number of terms and the Common difference.
help me plz ​

Answers

Answer 1

Answer:

[tex]n =16[/tex] --- Number of terms

[tex]d = \frac{8}{3}[/tex] --- Common difference

Explanation:

Given

[tex]a = 5[/tex] --- first term

[tex]T_n = 45[/tex]

[tex]S_n = 400[/tex]

Required

Determine the number of terms (n) and the common difference (d)

The sum of n terms of an AP is:

[tex]S_n = \frac{n}{2}(a + T_n)[/tex]

This gives:

[tex]400 = \frac{n}{2}(5 + 45)[/tex]

[tex]400 = \frac{n}{2} * 50[/tex]

[tex]400 = n * 25[/tex]

Divide both sides by 25

[tex]16 = n[/tex]

[tex]n =16[/tex]

The nth term of an AP is:

[tex]T_n = a + (n - 1)d[/tex]

This gives:

[tex]45 = 5 + (16 - 1) * d[/tex]

[tex]45 = 5 + 15 * d[/tex]

Subtract 5 from both sides

[tex]45 - 5= 5 - 5 + 15 * d[/tex]

[tex]40= 15 * d[/tex]

Divide both sides by 15

[tex]\frac{40}{15} = d[/tex]

[tex]\frac{8}{3} = d[/tex]

[tex]d = \frac{8}{3}[/tex]

4. What message do you get from the fable? Does it explain more than why the

5. Is the title effective, in your opinion? Explain, giving good reason.​

Answers

Explanation:

1-The world started with wuji (無極, nothingness) according to the Chinese creation myth. The Jade Emperor was the head of the pantheon, but not responsible for creation. In another creation myth, the Jade Emperor fashioned the first humans from clay and left them to harden in the sun

2-If the sun suddenly blinked out of existence, you'd have nothing to worry about — for the first eight minutes, anyway. After that, all hell would likely break loose. Still, it wouldn't be the instantaneous end to life on Earth that you might think.

3-Jade Emperor is a title used by multiple people throughout the story. Its actual political power in the setting is unknown, but it is suggested that it was once the highest position in the Heavenly Realm.

4-A rooster crows because he has an internal clock that helps him anticipate sunrise. Like all birds, roosters sing – or crow – in a daily cycle. Almost all animals have daily cycles of activity known as circadian rhythms that roughly follow the cycle of day and night. Roosters anticipate sunrise to get a head start on their daily hunt for food and defense of territory.

5-The original holder of the title. He was a Heavenly Realm God, father of the Princes of Natak, Master of the Nine-Tails Guardian, and Leader of Nox.

Read the excerpt from Chapter 4.
Anne of Green Gables

by Lucy Maud Montgomery

Matthew Cuthbert and his sister Marilla had decided to adopt a boy to help on their farm called Green Gables. When a girl, Anne, arrives, they are surprised. In this excerpt, Anne has just awoken after her first night at Green Gables.

Anne could evidently be smart to some purpose for she was down-stairs in ten minutes’ time, with her clothes neatly on, her hair brushed and braided, her face washed, and a comfortable consciousness pervading her soul that she had fulfilled all Marilla’s requirements. As a matter of fact, however, she had forgotten to turn back the bedclothes.

“I’m pretty hungry this morning,” she announced as she slipped into the chair Marilla placed for her. “The world doesn’t seem such a howling wilderness as it did last night. I’m so glad it’s a sunshiny morning. But I like rainy mornings real well, too. All sorts of mornings are interesting, don’t you think? You don’t know what’s going to happen through the day, and there’s so much scope for imagination. But I’m glad it’s not rainy today because it’s easier to be cheerful and bear up under affliction on a sunshiny day. I feel that I have a good deal to bear up under. It’s all very well to read about sorrows and imagine yourself living through them heroically, but it’s not so nice when you really come to have them, is it?”

“For pity’s sake hold your tongue,” said Marilla. “You talk entirely too much for a little girl.”

Thereupon Anne held her tongue so obediently and thoroughly that her continued silence made Marilla rather nervous, as if in the presence of something not exactly natural. Matthew also held his tongue,—but this was natural,—so that the meal was a very silent one.

As it progressed Anne became more and more abstracted, eating mechanically, with her big eyes fixed unswervingly and unseeingly on the sky outside the window. This made Marilla more nervous than ever; she had an uncomfortable feeling that while this odd child’s body might be there at the table her spirit was far away in some remote airy cloudland, borne aloft on the wings of imagination. Who would want such a child about the place?

Yet Matthew wished to keep her, of all unaccountable things! Marilla felt that he wanted it just as much this morning as he had the night before, and that he would go on wanting it. That was Matthew’s way—take a whim into his head and cling to it with the most amazing silent persistency—a persistency ten times more potent and effectual in its very silence than if he had talked it out.

When the meal was ended Anne came out of her reverie and offered to wash the dishes.

“Can you wash dishes right?” asked Marilla distrustfully.

“Pretty well. I’m better at looking after children, though. I’ve had so much experience at that. It’s such a pity you haven’t any here for me to look after.”

“I don’t feel as if I wanted any more children to look after than I’ve got at present. You’re problem enough in all conscience. What’s to be done with you I don’t know. Matthew is a most ridiculous man.”

“I think he’s lovely,” said Anne reproachfully. “He is so very sympathetic. He didn’t mind how much I talked—he seemed to like it. I felt that he was a kindred spirit as soon as ever I saw him.”

“You’re both queer enough, if that’s what you mean by kindred spirits,” said Marilla with a sniff. “Yes, you may wash the dishes. Take plenty of hot water, and be sure you dry them well. I’ve got enough to attend to this morning for I’ll have to drive over to White Sands in the afternoon and see Mrs. Spencer. You’ll come with me and we’ll settle what’s to be done with you. After you’ve finished the dishes go up-stairs and make your bed.”

Anne washed the dishes deftly enough, as Marilla who kept a sharp eye on the process, discerned. Later on she made her bed less successfully, for she had never learned the art of wrestling with a feather tick. But it was done somehow and smoothed down; and then Marilla, to get rid of her, told her she might go out-of-doors and amuse herself until dinner time.

Which of the following pairs of words are synonymous?

a:Their and they're
b :Odd and strange
c: Brave and cowardly
d: Dark and stormy

Answers

Answer:

B) Odd and Strange

Explanation:

This pair of words is synonymous.

Their and they're mean two different things.

Brave and cowardly are antonyms.

Dark and stormy have different definitions.

Hope it helps!

"Odd and strange" as a pair of words are synonymous. Thus, option 'B' is the correct option.

What is a synonym?

A term, morpheme, or phrase that in a particular language has the exact same meaning as another word, morpheme, or phrase is said to be a synonym. For instance, the terms begin, start, commence, and initiate are all synonyms of one another in the English language; they are interchangeable. A sentence's ability to retain its meaning when one form is substituted for another is the traditional test for synonymy. There is just one meaning in which words are regarded as synonymous.

In contrast to synonyms with vaguely similar meanings, which also share a larger denotational or connotational sememe and hence overlap within a semantic field, synonyms with the exact same meaning share a seme or denotational sememe. The former is occasionally referred to as cognitive synonyms, whereas the latter are referred to as near-synonyms, plesionyms, or poecilonyms.
