Answer:
BC = 6√3 inches
Explanation:
Given - A = 60°, C = 30°, and AB = 6 inches.
To find - What is the length of side BC?
Proof -
Given that ,
∠A = 60° , ∠C = 30° , AB = 6 inches
Let AC = x
By trigonometric identity, we get
cos(60°) = 6/x
⇒x = 6/cos(60°) = 12
⇒AC = 12
Now,
we have
AB = 6 inches , AC = 12 inches
By Pythagoras theorem , we get
(12)² = (6)² + (BC)²
⇒(BC)² = 144 - 36
⇒(BC)² = 108
⇒BC = √108
⇒BC = 6√3 inches
∴ we get
BC = 6√3 inches
How has the introduction of the automobile and, subsequently, the highway begun to fundamentally change the way cities are designed and function?
Answer:
The introduction of the automobile and, subsequently, the highway begun to fundamentally change the way cities are designed and function because these technological advances have allowed citizens to travel greater distances in less time: before the automobile, the horse was used to get around, which travels distances at about 30 kilometers per hour on average, and needs to rest after long stretches. Today, the car travels at average speeds of about 60 kilometers per hour and does not need breaks, other than the logical routine mechanical conditioning.
Thus, cities have been able to begin to expand horizontally, enlarging their contours because people no longer necessarily need to live near their centers, thanks to the mobility facilities that exist today.
In the third sentence of the third paragraph, the phrase “however volatile” primarily serves to
A. suggest that a characteristic of witty people is more common than generally supposed

C. identify one of the weaknesses typically exhibited by imaginative minds
D. qualify a generalization by narrowing the set of people to which it applies
E. strengthen a claim by indicating that it applies even to exceptional cases
Answer:
E. strengthen a claim by indicating that it applies even to exceptional cases
Explanation:
Answer E
Correct. In this sentence, the author makes the claim that melancholy can make one’s imagination “torpid” (sluggish), and that lack of appropriate occasions can prevent the mind from coming up with “sallies and excursions” (clever remarks). He strengthens the claim by extending it to the most exceptional cases when he indicates that it applies to any mind “however volatile,” that is, even to those that are normally the liveliest and most wide-ranging.
The phrase "however volatile" primarily means to strengthen a claim by indicating that it applies even to exceptional cases.
Option E is correct.
What is the meaning of the word volatile?The meaning of the word volatile is the ability of something to change abruptly or quickly without a prior prediction. However, its context usage may differ when used in a sentence.
The author claims in this statement that sadness may make one's imagination slow and that an absence of appropriate situations can prohibit the mind from emerging with "sallies and explorations".
He supports the assertion by expanding it to the most extreme circumstances when he says it relates to any mind i.e. "however volatile," which implies to those that are generally the most lively and diverse.

Write a summary of the following excerpt from “Why I Wrote 'The Yellow Wallpaper" by Charlotte Perkins
Gilman.
For many years I suffered from a severe and continuous nervous breakdown tending to melancholia--and beyond
During about the third year of this trouble I went, in devout faith and some faint stir of hope, to a noted specialist in
nervous diseases, the best known in the country. This wise man put me to bed and applied the rest cure, to which
a still-good physique responded so promptly that he concluded there was nothing much the matter with me, and
sent me home with solemn advice to "live as domestic a life as far as possible," to "have but two hours' intellectual
life a day," and "never to touch pen, brush, or pencil again" as long as I lived. This was in 1887
Answer:
Gilman felt very melancholy and was having a severe nervous breakdown. This mental state was maintained for three years, which made her look for a specialist in nervous diseases, who would examine her and help her to heal. The specialist stated that she did not have any serious illness, but that she needed to rest as long as she lived to be cured.

An unintended consequence of eco-tourism is
an increased presence of multinational corporations in the area
increased reliance on sustainable energy sources
a population boom in the area
a reduction in airports as green policies are implemented
the establishments of additional national parks
Answer: An increased presence of multinational corporations in the area
An unintended consequence of eco-tourism is the increased presence of multinational corporations in the area.
What is eco-tourism ?While eco-tourism can provide economic benefits to the local community and promote conservation efforts, it can also attract large corporations that seek to profit from the natural resources and landscapes that draw tourists. These corporations may exploit the environment for their own gain, leading to ecological damage and loss of biodiversity.
In contrast, eco-tourism can also lead to an increased reliance on sustainable energy sources. As tourists and locals become more aware of the impacts of their activities on the environment, they may seek out alternative energy sources such as solar, wind, or hydro power. This can help reduce greenhouse gas emissions and promote a cleaner, healthier environment.
Eco-tourism may also lead to a population boom in the area. As more tourists visit and more jobs are created in the tourism industry, the local population may grow. This can put pressure on local resources and infrastructure, leading to overcrowding and environmental degradation.
While eco-tourism can lead to a reduction in airports as green policies are implemented, it may also lead to the establishment of additional national parks.
As tourists and locals alike recognize the importance of protecting natural areas, governments may designate more land as protected areas or national parks, leading to increased conservation efforts and the preservation of biodiversity.

The side of a cube is decreasing at a rate of 9 millimeters per minute.
At a certain instant, the side is 19 millimeters.
What is the rate of change of the volume of the cube at that instant (in cubic millimeters per minute)?
Answer:
the rate of change of the volume of the cube is -9747 cubic millimeters per minute
Explanation:
The computation of the rate of change of the volume of the cube is given below:
As we know that
The volume of the cube is x^3
Now differentiate it with time t
So
dV÷ dt = 3x^2 dx ÷ dt
Now put the values
= 3(19)^2 (-9)
= -9747 cubic millimeters per minute
hence, the rate of change of the volume of the cube is -9747 cubic millimeters per minute

The graph shows the price of a good compared to the quantity demanded.
A graph titled Demand for Microwave Ovens has quantity demanded on the x-axis, from 0 to 50 in increments of 5, and price in dollars on the y-axis, from 0 to 70 in increments of 10. A line with negative slope contains 2 points. Point (D 1, P 1) is at (15, 50), and point (D 2, P 2) is at (20, 30).
This graph demonstrates how
the amount produced slightly changes with the price.
the amount produced greatly changes with the price.
the quantity demanded changes slightly with the price.
the quantity demanded changes greatly with the price.
Answer:
the quantity demanded changes slightly with the price.
Explanation:
As was shown in the chart title, we can see that the chart will present the demand for microwave oven and what is the relationship between this demand and the price of the product, since the amount of demand is in the x axis and the amount of the price is on the axis y. As we can see, the graph has a negative slope, which links the values of demand and price in an inversely proportional way. This shows that the amount of demand changes slightly with the price, and as the price increases, demand decreases.
From the graph, we can see that the quantity demanded changes slightly with the price.
What is demand and supply?Demand and supply is the relationship in economics that shows the connection between the quantity of goods to be sold and the consumer's willingness to buy. This relationship is expressed in this graph.
