1-SinQ = (sec Q tanQ)2
1+sinQ
Answer:
The answer is below
Explanation:
Prove that:
[tex]\frac{1+sinQ}{1-sinQ}=(secQ + tanQ)^2[/tex]
Trigonometric identities are equalities involving trigonometric functions for which both sides of the equality are equal and defined. Some trigonometric identities are:
sin²Ф + cos²Ф = 1; 1/cosФ = secФ; 1/sinФ = cosecФ; cosФ/sinФ = cotФ; 1 + tan²Ф = sec²Ф
Given:
[tex]\frac{1+sinQ}{1-sinQ}\\\\Divide\ through\ by \ cosQ:\\\\ \frac{\frac{1}{cosQ} +\frac{sinQ}{cosQ} }{\frac{1}{cosQ} -\frac{sinQ}{cosQ} }=\frac{secQ+tanQ}{secQ-tanQ}\\\\Next, rationalize\ the\ denominator\ by \ multiplying\ the\ numerator \ and\ \\denominator\ by\ secQ+tanQ:\\\\\frac{secQ+tanQ}{secQ-tanQ}*\frac{secQ+tanQ}{secQ+tanQ}=\frac{(secQ+tanQ)^2}{sec^2Q+secQtanQ-secQtanQ-tan^2Q}\\\\=\frac{(secQ+tanQ)^2}{sec^2Q-tan^2Q} ;\ But sec^2Q-tan^2Q=1,hence:\\\\[/tex]
[tex]\frac{(secQ+tanQ)^2}{sec^2Q-tan^2Q} =\frac{(secQ+tanQ)^2}{1}=(secQ+tanQ)^2\\\\\frac{1+sinQ}{1-sinQ}=(secQ+tanQ)^2[/tex]

Jefferson Company purchased equipment on January 1, 2017. The equipment cost $60,000 and has an estimated life of 8 years and a salvage value of $8,000. What was the depreciation expense for the equipment for 2018 under the double-declining-balance method?
Answer: $11250
Explanation:
Based on the information given in the question, the depreciation expense for the equipment for 2018 under the double-declining-balance method will be calculated thus:
Cost of Equipment = $60,000
Salvage Value = $8,000
Useful Life = 8 years
Double-declining-balance Depreciation Rate will be calculated as:
= 2 / Useful Life
= 2 / 8
= 25%
For 2017:
Beginning Book Value = $60,000
Depreciation Expense = 25% × $60,000 = $15,000
Ending Book Value = $60,000 - $15,000 = $45,000
2018:
Beginning Book Value = $45,000
Depreciation Expense = 25% × $45,000 = $11,250
Therefore, the depreciation expense for the equipment for 2018 under the double-declining-balance method is $11250.
Note that:
Ending Book Value = Beginning Book Value - Depreciation Expense

he was never satisfied/ he was one of the richest men in the world
Answer:
He was never satisfied even though he was one of the richest men in the world.
Explanation:
"Even though" is a subordinating conjunction that is used to introduce a statement that is surprising or unexpected. It is also used to present a stronger emphasis on the concerned statements.
The given sentence presents two parts or qualities of a person. The first states how he's never satisfied while the second states the contrast with the first.
Therefore, using "even though" in between the two statements will present the contrasting yet unexpected statement about the person.
In using the subordinating conjunction "even though", the statement that "he's never satisfied" is contrasted with the other statement "he's one of the richest men in the world". His richness does not seem to make him satisfied, which seems unexpected, in most people's opinion as we tend to think money can make us happy.
Thus, the correct sentence structure will become-
He was never satisfied even though he was one of the richest men in the world.

Answer:
The benefits of forgetting the past is that you liberate yourself from many things that might pain you. It could be that in the past you’ve faced a certain situation that made you feel really bad or anxious, but moving on from that can make you feel better. Or if you got mad st someone you possibly betrayed you, releasing yourself from resentment helps you have inner peace because your no longer resenting what that person did to you. I guess the main cause would be wanting to finally have peace and not worry about what once happened, rather you let it go just so that way you can be happy.
Explanation:
It’s a short summary, but it’s meaningful and I hope it helps you out :)

Read the excerpt from The Dark Game.
But how would Hall get that telegram? That would take some doing, he admitted. Then Hall remembered Mr. H., one of his trusted operatives. It was Mr. H. who had alerted MI8 to the suspicious activities of Sweden's chargé d'affaires in Mexico City, Folke Cronholm. Sharp-eyed Mr. H. had noticed that Cronholm was making frequent visits to the telegraph office, far more visits than one would expect from a representative of the Swedish government, given the limited relationship between that government and Mexico.
Which inference can a reader make based on the information in the excerpt?

In at least 150 words, discuss the author's choice of setting in the story "through the tunnel" How does it impact the themes and the progression of the plot?
Answer:
The author's choice of setting reflects the mood and tone of the book/play/movie, as well as the personalities of the characters. Because the characters are all in the environment, whatever environment is chosen has an influence on the themes. Depending on the type of scenario they are in, the characters can grow and learn new things. The setting advances the storyline because if the atmosphere of a book is cheerful but the environment is gloomy and menacing, the entire story line will be changed. If all of the characters are joyful individuals, and they travel from a beautiful day at the beach to a haunted mansion, their personalities may change as a result of the situation. Characters, topic, and storyline are all influenced by the author's choice of place.
