E. Stage 5

Took me some time but I think I solved it

A. To find the area of region S, we need to integrate the difference between the functions f(x) and g(x) with respect to x, from 0 to 2. Since f(x) is defined piecewise, we need to split the integral into two parts:Area of region S = ∫(f(x) - g(x)) dx from x=0 to x=1 + ∫(f(x) - g(x)) dx from x=1 to x=2Evaluating each integral separately using the given functions:Area of region S = [(7/2) - (5/2)] dx from x=0 to x=1 + [(5/2) - (4/3)x^(3/2)] dx from x=1 to x=2

Area of region S = [1] dx from x=0 to x=1 + [(5/2) - (4/3)*2^(3/2)] - [(5/2) - (4/3)] dx from x=1 to x=2

Area of region S = 1 + [5/2 - (4/3)2^(3/2) + 4/3 - 5/2] = 2/3 + (5/2 - 4/32^(3/2))Therefore, the area of region S is approximately 1.302 units.

b. To find the volume of the solid generated when region S is revolved about the horizontal line, we need to use the disk method. Each cross-section perpendicular to the horizontal line is a disk with radius equal to the distance between the y-axis and the function f(x) minus the distance between the y-axis and the function g(x), and thickness dx.Volume of solid = π∫(f(x)^2 - g(x)^2) dx from x=0 to x=2Using the given functions f(x) and g(x):Volume of solid = π∫(7x - x^(3/2))^2 dx from x=0 to x=2

Volume of solid = π∫(49x^2 - 14x^(5/2) + x^3) dx from x=0 to x=2

Volume of solid = π[(49/3)2^3 - (14/7)(2^(7/2) - 1) + (1/4)*2^4]Therefore, the volume of the solid generated when region S is revolved about the horizontal line is approximately 59.542 units^3.

c. Each cross-section perpendicular to the x-axis is a rectangle with height equal to 7 times the length of its base in region S. Since the length of the base can be represented as (f(x) - g(x)), the area of each cross-section can be represented as 7(f(x) - g(x))dx. Therefore, the volume of the solid can be expressed as:Volume of solid = ∫7(f(x) - g(x)) dx from x=0 to x=2We already calculated the integral in part (a), so substituting that expression:Volume of solid = 7Area of region S

Volume of solid = 7(2/3 + 5/2 - 4/32^(3/2))

Volume of solid = 14/3 + 35/2 - 28/3*2^(3/2)Therefore, the integral expression for the volume of this solid is 14/3 + 35/2 - 28/3*2^(3/2) times the appropriate units^3.

The Chapley-Curtis debate centered around the nature of "spiral nebulae" and their connection to our own Milky Way galaxy. In the early 20th century, astronomers in class debated whether these nebulae were separate "island universes" or part of our own galaxy. The debate was sparked by the observations and interpretations of two prominent astronomers: Harlow Shapley and Heber Curtis.

The Chapley-Curtis debate concerned the nature of spiral nebulae and their connection to the Milky Way galaxy.

At the time, the prevailing view, supported by Harlow Shapley, was that spiral nebulae were "spiral-shaped" regions within our Milky Way. Shapley argued that these objects were relatively small and located within our galaxy, and he placed the Sun near the center of the Milky Way. On the other hand, Heber Curtis proposed that spiral nebulae were distant, independent "island universes" outside of our galaxy, containing their own stars and galaxies. Curtis believed that these nebulae were immense and located at vast distances from us. The debate was mainly fueled by disagreements over the nature of the observed spiral nebulae and their apparent distance and size. It wasn't until the 1920s, with the work of Edwin Hubble and his discovery of Cepheid variable stars in the Andromeda Nebula, that the consensus shifted towards Curtis' view. Hubble's observations provided compelling evidence that spiral nebulae were indeed separate galaxies, far beyond the bounds of our Milky Way, effectively settling the Chapley-Curtis debate.

Answer: 4. C. Emphasize the disconnect between government spending on agriculture and its impact on Americans' diets.
The author cites a statistic about the US government's subsidization of the farming industry in the final sentence of the fourth paragraph to emphasize the disconnect between government spending on agriculture and its impact on Americans' diets. The author mentions that the last five-year farm bill included $300 billion in spending but such spending has never been used as a tool to improve the population's nutrition. The author points out that subsidies to farmers have made corn and soy cheaper than fruits, vegetables, and whole grains and that food companies have built entire brands based on these cheaper commodities which contribute to unhealthy processed foods, highlighting the disconnect between government spending and the quality of the calories consumed by Americans.

8. A. analyzing one type of government solution to dietary change to proposing a more individualized approach to the problem.

In the seventh paragraph, the authors acknowledge the resistance in the US to taxing unhealthy foods. As a result, they shift from analyzing a government-based solution to the problem of unhealthy eating habits to proposing a more individualized approach. This new approach is likely based on the recognition that government intervention in the form of taxes may not be feasible or effective. By proposing a more individualized approach, the authors aim to overcome the obstacles to healthy eating habits and find a way to effectively address the issue.

“I have a customer who is very taciturn: "He won't speak with you?" (Option B)

Taciturn means being habitually untalkative or reluctant to speak. A person who is taciturn is typically quiet and reserved, and may not speak much or engage in conversation readily. Taciturnity can be a personality trait or a temporary state of being and can be due to various factors such as shyness, introversion, or a reluctance to reveal personal thoughts or feelings.

Being taciturn does not necessarily imply a lack of intelligence or social skills, and people who are taciturn can still be friendly and engaging when they do speak.

To handle customers who are taciturn, it may be helpful to approach them in a friendly and non-threatening manner and give them space to speak at their own pace.

Answer: If you were to plot the point 40 degrees north latitude and 20 degrees east longitude, the two hemispheres from the provided picture that your point would be in is OC. W and X.

Explanation: 40 degrees north latitude means that the point is located in the Northern Hemisphere. 20 degrees east longitude means that the point is located in the Eastern Hemisphere. So, the point would be located in both the Western Hemisphere (W) and the Eastern Hemisphere (X) as shown in the picture.

The point plotted at 40 degrees north latitude and 20 degrees east longitude would be located in the Northern (Y) and Eastern (X) hemispheres if in the provided picture, W, X, Y and Z represent the Western, Eastern, Northern, and Southern hemispheres.

The plot of 40 degrees north latitude and 20 degrees east longitude would be located in two hemispheres. Because the point is 40 degrees north, it is located in the Northern Hemisphere. By virtue of being 20 degrees east, it is within the Eastern Hemisphere. Therefore, if the letters W, X, Y, and Z respectively represent the Western, Eastern, Northern, and Southern hemispheres in the provided picture, your point would fall within hemispheres Y and X.

Answer:

One of the major arguments against price ceilings and price floors is that they can cause illegal trades or black markets to emerge to fill the market demand. When the government sets a price ceiling below the equilibrium price, it creates a shortage of the product. This shortage may cause some consumers to turn to the black market where the product is sold at a higher price. Similarly, when the government sets a price floor above the equilibrium price, it creates a surplus of the product. This surplus may cause some producers to sell the product on the black market at a lower price.

Answer: refineries, where the crude is processed into gasoline and other fuels

Explanation:

Before oil can be used, it needs to be processed into various fuels such as gasoline and airplane fuel. This is done in refineries that extract these fuels by using boiling point technology.

Oil trains transport oil to these refineries for the processing to be done. Options A and B are ruled out because oil needs to be processed first and option C is rued out because oil is not normally transported by air because it is expensive and dangerous.

Answer:

Humans were nomads. Their wandering was mainly in search of food and shelter. When they found that certain places had an abundance of food – plant food or animals for hunting, they stayed on. They observed the plants, their growth and when these food sources diminished, they grew plants themselves, from the seeds they collected. This is how agriculture came about.

When humans stopped their nomadic ways and stayed together, it paved the way for formation of the human social structure. Hierarchies were established in due course.
