Is it possible for a person to incur an opportunity cost without spending any money? Explain.

Opportunity cost is what is given up when a scarce resource is used in a certain way. It is possible for a person to incur an opportunity cost without spending money. While money is a scarce resource, there are other scarce resources that don’t involve money.


For example, time is a scarce resource. When a person has a limited amount of time and needs to do many things, a person will incur an opportunity cost when he or she chooses to use time in a given away. Let’s say a person has one free hour in a given evening. The person has a homework assignment that will take an hour to complete. This person also has an opportunity to visit a sick relative in a nursing home. This visit will last an hour. If the person decides to visit the sick relative, the opportunity cost will be not being able to do the homework assignment.


It is possible to incur an opportunity cost in situations unrelated to spending money.

What is the theme of The Pearl by John Steinbeck?

One of the main themes of The Pearl is the destructive power of greed. Kino disregards the safety and love of his family to pursue selling the pearl he finds. When the pearl brokers offer him a poor price, Juana, his wife, tries to throw the pearl into the ocean. In response, Kino beats her savagely, and then a series of misfortunes befall him. He kills a man who tries to rob him, and, as a result, he is forced to flee his home with his family. His house then burns down, and the boat in which he tries to flee has a hole in the bottom. When he attempts to flee by land, the men sent to pursue him wind up killing his baby. Left with nothing, he realizes the error of his ways and tosses the pearl back into the ocean. His greed caused his undoing, the unraveling of his family, the death of his baby, the destruction of his home, and the sorrow of his loving wife. 

Were there any specific laws or bills passed throughout the early 1970s that protected gay rights in California and/or the West Coast?

The answer to your question is yes; however, most of the laws that were passed were specific to certain states.


For example, the state of California passed a consenting adults law on May 2, 1975. The bill was named after San Francisco assemblyman Willie Brown. Passage of the bill allowed for consensual sex between adults of all varieties of sexual inclinations. The new law took effect on January 1, 1976. Here is a link documenting the Consenting Adults Act of 1975 in California.


Prior to this, San Francisco had already passed a homosexual rights ordinance in 1972. The ordinance prohibited discrimination against the LGBTQ community in the area of employment in the city of San Francisco. In 1978, another ordinance was passed; this time, the law prohibited discrimination against the LGBTQ community in the area of employment and housing in the private sector. Here's a timeline of gay rights history in the 1970s in San Francisco.


In Washington state, Seattle passed an ordinance prohibiting employment and housing discrimination against gays in 1973. That same year, the City Council in Berkeley, California, prohibited companies that engaged in business with the city from discriminating against the LGBTQ community.


In 1973, congressional representatives in Oregon voted on House Bill 2930 which prohibited discrimination against homosexuals in the area of employment. However, it didn't garner enough votes and wasn't passed. However, a 1974 ordinance that prohibited discrimination against homosexuals in municipal employment passed in Portland, Oregon. Also, anti-sodomy laws that criminalized homosexual behavior were repealed in Washington, California, and Oregon in the 1970s.

What rhetorical devices and strategies does Langston Hughes use in the short story, "That Word Black"?

The first and most obvious device that the author use is repetition. This is obvious when the speaker, Simple, consistently uses the word 'black' as a reference to the point he wishes to make, as in the following extracts:



"...the word black,... I reckon it all started with a black cat meaning bad luck. Don't let one cross your path!


"Next, somebody got up a blacklist on which you get if you don't vote right. Then when lodges come into being, the folks they didn't want in them got blackballed. If you kept a skeleton in your closet, you might get blackmailed. And everything bad was black. When it came down to the unlucky ball on the pool table, the eight-rock, they made it the black ball. So no wonder there ain't no equal rights for the black man."



The text follows this trend throughout and repetition is similarly used in references to the word white. In this instance, though, the writer uses contrast in order to highlight its distinction to black. He alludes to the significant contrasts in connotation that the two words have. Whatever is bad is black, he suggests white people believe, and whatever is good is white.


He proposes that when his day comes - a common idiom suggesting a future time when he is in control or successful - he will turn things around and reverse the connotations that the two words have.


The irony throughout the text is patently obvious and is emphasized in the final paragraph when Simple says:



The earth is black and all kinds of good things comes out of the earth. Everything that grows comes out of the earth. Trees and flowers and fruit and sweet potatoes and corn and all that keeps mens alive comes right up out of the earth––good old black earth. Coal is black and it warms your house and cooks your food. The night is black, which has the moon, and a million stars, and is beautiful. Sleep is black, which gives you rest, so you wake up feeling good. I am black. I feel very good this evening.



It is evident that he believes that the connotations are quite meaningless and without context. The prejudice associated with words is based on a particular mindset informed by prejudice and a generally adopted and irrational stereotype. There is no foundation or evidence to prove that the connotation is, in fact, true.


The last line ends with a rhetorical question a device the author also uses throughout the story:



"What is wrong with black?"



The answer is obvious and easy. The reader's response, however, will be informed by his own subjective understanding of the word derived from what he has learnt or experienced and what he chooses to believe.

What does the Prince hope to do by locking himself in the castle in "The Masque of the Red Death" by Edgar Allan Poe? Why would also he have the...

The Prince is attempting to keep himself and his guests in denial. His kingdom is dying off from the Red Death. He wants to make sure no one can get in and infect his castle, and he also wants to make sure no one can leave.


Prince Prospero is described as “dauntless,” meaning he is not intimidated by anything. The fact that he is not intimidated by the plague demonstrates this. Unfortunately, instead of trying to help his people or find a cure, he builds himself an impenetrable castle and holes himself up inside it with a thousand of his closest friends.



When his dominions were half depopulated, he summoned to his presence a thousand hale and light-hearted friends from among the knights and dames of his court, and with these retired to the deep seclusion of one of his castellated abbeys. This was an extensive and magnificent structure, the creation of the prince's own eccentric yet august taste.



The prince is avoiding reality. He is not just trying to make sure that death can’t get in; he is also trying to avoid facing his responsibilities. None of his people can leave, either. They are all going to stay, party, and pretend time stopped.


The party and masquerade are an example of the Prince’s insane desire to evade reality.



It was a voluptuous scene, that masquerade. But first let me tell of the rooms in which it was held. There were seven—an imperial suite. . . Here the case was very different; as might have been expected from the duke's love of the bizarre.



The prince and his courtiers can't keep pretending nothing has happened outside, and they can’t go outside because that will destroy the illusion. As a result, they barricade themselves inside and seal off the walls.

In the story "Lyddie" by Katherine Paterson, who are the Quakers?

In the story, the Quakers not only belong to a religious order, but members of the sect are also Lyddie's neighbors. For example, Quaker Stevens owns a farm near Lyddie's family's property.


In Chapter Two, Lyddie and Charles are being sent to work as a miller's helper and a housemaid respectively so that they can help to pay off their father's debts. Before they leave, they have to take the horse and cow to a Mr. Westcott to pay off a debt they owe him. Lyddie and Charles hope to sell their calf to Quaker Stevens for a good price.


Even though Quakers as a rule are expected to live simply, Lyddie notices that the Stevens farm is a substantial one. The farmer is kind to the children and buys the calf for twenty five dollars. Then, he invites them in for the noon-day meal. Both children notice that the kitchen itself is larger than their whole cabin and shed thrown together. The meal is lavish in the children's estimation, and the Stevens family is wealthy enough to own its own loom.


In the early chapters of the story, it is Quaker Stevens who lends his bull to the family as a favor: the bull mates with the Worthen cow, and each spring, calves are born and then sold for money. This is partly how Lyddie, her brother, and their mother survive after Lyddie's father leaves the family.


So, in the story, the Quakers are Lyddie and Charles' neighbors. They are kind, compassionate, and loving people who do the best they can to help Lyddie and her family, despite Lyddie's mother's suspicion of Quakers as "heathens" and "abolitionists." Later, Luke Stevens (the youngest son) asks Lyddie to marry him, but she decides to attend college instead. The novel ends ambiguously, and we are left to wonder if Lyddie will later accept Luke's suit.

`int (du)/(u sqrt(5 - u^2)) ` Evaluate the integral

`int(du)/(usqrt(5-u^2))`


` `


Let


`u=sqrt5sin(theta)`


`(du)/[d(theta)]=sqrt5cos(theta)`


`(du)=sqrt5cos(theta)d(theta)`



`int(du)/[usqrt(5-u^2)]`


`=int1/(sqrt5sin(theta))*[sqrt(5)cos(theta)d(theta)]/sqrt[5-(sqrt5sin(theta)^2)]`


`=int[cot(theta)d(theta)]/sqrt(5-5sin^2theta)`


`=int[cot(theta)d(theta)]/sqrt[5(1-sin^2theta)]`


`=int[cot(theta)d(theta)]/sqrt(5cos^2theta)`


`=int[cot(theta)d(theta)]/[sqrt(5)cos(theta)]`


`=int[cos(theta)d(theta)]/[sqrt(5)sin(theta)cos(theta)]`


`=int[d(theta)]/[sqrt(5)sin(theta)]`


`=int[csc(theta)d(theta)]/sqrt(5)`


`=1/sqrt(5)intcsc(theta)d(theta)`


`=1/sqrt(5)ln|sqrt(5)/u-sqrt(5-u^2)/u|+C`


`=1/sqrt(5)*ln|[sqrt5-sqrt(5-u^2)]/u|+C`



The final answer is 


`=1/sqrt(5)*ln|[sqrt5-sqrt(5-u^2)]/u|+C`
