Answer: There are many possible models that could fit these x-intercepts and y-intercept constraints, but two common models are:
A polynomial function of degree 4:
f(x) = a(x + 4)(x + 2)(x - 1)(x - 3) + 5
where a is a constant determined by the specific requirements of the model. This function has x-intercepts at -4, -2, 1, and 3, and the y-intercept is at f(0) = 5.
A piecewise function:
f(x) =
5, if x < -4
5 + b(x + 4), if -4 <= x < -2
5 + b(x + 4) + c(x + 2), if -2 <= x < 1
5 + b(x + 4) + c(x + 2) + d(x - 1), if 1 <= x < 3
5 + b(x + 4) + c(x + 2) + d(x - 1) + e(x - 3), if x >= 3
where b, c, d, and e are constants determined by the specific requirements of the model. This function has x-intercepts at -4, -2, 1, and 3, and the y-intercept is at f(0) = 5.
These are just two examples of possible models that fit the x-intercepts and y-intercept constraints. Other models could also work, depending on the specific requirements of the problem.
How is including or featuring Latinx Contemporary artists in the art canon breaking the rules of the history of photography?
Adding Latinx contemporary artists to the art canon does not automatically go against the history of photography . Instead, it questions and broadens the traditional art collection, which has usually been controlled by art created by white males.
What is the photographyThe story of photography, similar to other art styles, has often been unfair and focused mainly on Europe. It has frequently left out the contributions of marginalized communities, like Latinx artists, women, people of color, and others. This exclusion has made people not understand the full range of how artists express themselves in photography.
Art historians and curators want to fix historical bias by including Latinx contemporary artists in the art canon. They hope to show a more complete and accurate picture of the different voices and viewpoints in the art world.

Explain one way in which conservatism in the period circa 1750-1900 resisted social change in russia and japan
One way in which conservatism in the period circa 1750-1900 resisted social change in Russia and Japan was through the maintenance of traditional social hierarchies.
In Russia, the conservative Tsarist regime resisted social change by maintaining the serfdom system, which kept peasants tied to the land and under the control of the nobility. Despite some attempts at reform, such as the Emancipation Reform of 1861, the Tsarist regime continued to resist any significant social change that would threaten the traditional social order.
Similarly, in Japan, the conservative Tokugawa Shogunate resisted social change by maintaining the strict social hierarchy of the feudal system. This included the samurai class at the top, followed by peasants, artisans, and merchants at the bottom. The Tokugawa Shogunate also enforced strict isolationist policies, which prevented outside influences from disrupting the traditional social order.
Overall, conservatism in both Russia and Japan during this period sought to maintain traditional social hierarchies and resist any social change that would threaten the established order.

As a country becomes more affluent how does its diet change? What affect(s) does this have on the environment?
Answer: As a country becomes more affluent, its diet typically changes towards a more Western-style diet, which is often high in meat, dairy, and processed foods. This shift is due to increased purchasing power and changing cultural attitudes towards food.
This change in diet has significant impacts on the environment. For example, the production of meat, particularly beef and pork, requires large amounts of feed, water, and land, and contributes significantly to greenhouse gas emissions. The production of dairy and other animal-based products also has a significant environmental impact, as it requires large amounts of feed, water, and land and contributes to deforestation, water pollution, and soil degradation.
In addition, the increased consumption of processed foods and high-calorie snacks contributes to deforestation, as the production of these foods often requires large amounts of palm oil, which is associated with deforestation and the loss of habitat for wildlife. The production of these foods also contributes to greenhouse gas emissions, as the production of palm oil and other ingredients often involves the use of fossil fuels.
Moreover, the rise in meat and dairy consumption also puts pressure on global resources, including land, water, and crops, which could limit the availability of these resources for future generations. The over-exploitation of these resources could lead to a decline in biodiversity and the loss of important ecosystem services, such as pollination and pest control.
Therefore, as a country becomes more affluent, the shift in its diet towards a more Western-style diet has significant impacts on the environment, including increased greenhouse gas emissions, deforestation, and resource depletion, and it highlights the importance of sustainable food production and consumption practices.

Beginning in 2005, many nations around the world began to phase out incandescent lightbulbs in favor of newer and more energy-efficient lightbulbs. A 60-watt incandescent lightbulb provides about 800 lumens(a measure of brightness) of light while a comparably bright LED bulb uses 9 watts.
a. Calculate the percent change in energy use for switching to LEDs.
b. Incandescent light bulbs are 90% inefficient. If an incandescent light bulb is used for 8 hours everyday, and we assume all inefficiencies are converted to heat, calculate how much energy will be lost as heat from a single bulb in one year. (1 watt=1joule/sec)
c. LEDs last about 50,000 hours, while the traditional incandescent bulbs they replace last about 1,000 hours. If the average cost for an incandescent light bulb is $0.70, calculate the price an LED bulb would need to be to match the price per hour of an incandescent.
Calculate the potential reduction in petroleum consumption (in gallons of gasoline per ear) that could be achieved in the United States by large-scale adoption of electric vehicles under the following assumptions:
-The average fuel economy of sedan is 25.5 miles per gallon of gasoline.
-The average car in the US is driven 13,500 miles per year. - There are 260 million passenger cars in the US
- An additional 7% of the US passenger car fleet is projected to be electric in 2030
Answer:
a.
To calculate the percent change in energy use for switching to LEDs, we can use the following formula:
percent change = (initial value - final value) / initial value * 100%
The initial value is the energy used by a 60-watt incandescent bulb, which is 60 watts. The final value is the energy used by a comparable LED bulb, which is 9 watts. So we have:
percent change = (60 - 9) / 60 * 100%
percent change = 85%
So switching to an LED bulb reduces energy use by 85%.
b.
To calculate the amount of energy lost as heat from a single 60-watt incandescent bulb in one year, we first need to calculate the amount of energy used by the bulb in one year. We know that a watt is equal to a joule per second, so we can calculate the amount of energy used by the bulb in one second:
60 watts = 60 joules per second
In one hour, the bulb will use:
60 joules per second x 3600 seconds per hour = 216,000 joules per hour
In one day (assuming 24 hours), the bulb will use:
216,000 joules per hour x 24 hours = 5,184,000 joules per day
In one year (assuming 365 days), the bulb will use:
5,184,000 joules per day x 365 days = 1,891,360,000 joules per year
However, we also know that incandescent bulbs are 90% inefficient, meaning that 90% of the energy is lost as heat. So, we can calculate the amount of energy lost as heat:
1,891,360,000 joules per year x 0.9 = 1,702,224,000 joules per year
Finally, we can convert this to kilojoules:
1,702,224,000 joules per year ÷ 1000 = 1,702,224 kilojoules per year = 157.68 kJ per year
Therefore, the amount of energy lost as heat from a single 60-watt incandescent bulb in one year is 157.68 kJ.
c.
To calculate the price an LED bulb would need to be to match the price per hour of an incandescent, we can use the following formula:
price per hour = cost / lifespan
The cost of an incandescent bulb is $0.70 and its lifespan is 1,000 hours, so the price per hour is:
price per hour = $0.70 / 1,000 hours
price per hour = $0.0007/hour
To match this price per hour, the price of an LED bulb would need to be:
50,000 * x = 1,000 * $ 0.70
x = 1000 * 0.70 / 50000
x = $ 0.014
So an LED bulb would need to cost $0.014 to match the price per hour of an incandescent bulb.
d.
The part 137,647.06 million gallons per year represents the petrol consumption by gasoline vehicles.
And, we have to calculate the reduction in the consumption of petroleum (in gallons of gasoline per year) that could be achieved in the United States by large-scale adoption of electric vehicles, so we have to take the 7% of the per year petroleum consumption since 7% of the US passenger car fleet is projected to be electric in 2030.
Hence the correct answer would be 7% of 137,647.06 which is equal to 9,635.30 million gallons per year will be saved.

History Writing by Margot Lee Shetterly
Paragraph 13:
When the managers couldn't satisfy the demand with only white employees, the government decided to hire African Americans. A civil rights leader named A. Philip Randolph encouraged President desegregation of the federal government and defense industry and created the Fair Employment Practices Committee. This executive order opened up new and exciting opportunities for African Americans, allowing them to work side-by-side with white people during the war.
In paragraph 13, sentence 1, mark both the cause and effect. What does this cause-and effect relationship explain African American women as mathematicians at Langley?
Answer: The cause in the sentence is "the managers couldn't satisfy the demand with only white employees." The effect is "the government decided to hire African Americans."
This cause-and-effect relationship explains that due to the inability of the managers to meet the demand for labor with only white employees, the government decided to hire African Americans. However, the relationship does not specifically explain African American women as mathematicians at Langley.
