The rhetorical technique that Douglass use in this sentence is option  C. Antithesis

In the above  sentence, Douglass creates a contrast between two ideas: the unfavorable point of view from which he is forced to view the deeds of others, and the admiration he feels for those deeds despite this unfavorable point of view.

Antithesis is a rhetorical device that involves the use of contrasting ideas, phrases, or words in a balanced or parallel structure.

He sets up the idea of not being able to view the deeds with less than admiration, and the idea of a unfavorable point of view. This creates a contrast between the two ideas, which is the definition of Antithesis.

Therefore, based on the context of the above, Asyndeton is a literary technique in which conjunctions are omitted in a series of related clauses. This sentence doesn't have this technique.

Answer:

The boundaries between Earth's tectonic plates are often marked by areas of intense seismic activity, including earthquakes. Most earthquakes occur along plate boundaries, where the movement of the plates can cause the buildup of stress in the Earth's crust. The majority of earthquakes occur at the boundaries between the tectonic plates, particularly at the edges of the lithosphere where the crust is thinnest and the most susceptible to movement. This is because the plates are constantly moving and interacting with each other, which can cause the release of built-up energy in the form of earthquakes.

Answer:

Earthquakes and volcanoes are the direct result of the movement of tectonic plates at fault lines. The term fault is used to describe the boundary between tectonic plates. Most of the earthquakes and volcanoes around the Pacific ocean basin—a pattern known as the “ring of fire”—are due to the movement of tectonic plates in this region. if it helps can you give me brainliest cause I need 10 brainliest

Answer: The correct answer is option A: To reinforce the pain that results from the inhumane treatment of slaves.

Explanation: The purpose of the analogy is to reinforce the inhumane treatment of slaves. The use of the analogy comparing slaves to animals being sold at a market suggests that they are being treated as property rather than as human beings. The comparison to horses, sheep, and swine being "knocked off to the highest bidder" further emphasizes the dehumanizing nature of the slave trade.

Answer:

The probability is [tex]0.2130[/tex]

Explanation:

Let's start by defining our variable :

[tex]X:[/tex] '' Number of students completing a degree in four year college enrolled in a two year college in the previous 10 years ''

Now, let's suppose that we have an experiment compounded by a series of test. Each test result can be classified as '' success '' or '' failure ''. In each test, the success probability is called ''p'' and the failure probability is '' 1 - p ''. Both probabilities don't change from test to test and we also suppose that exists independence between each test. Therefore, the random variable [tex]Y[/tex] : '' Number of successes in n tests '' can be modeled as a binomial random variable. We write :

[tex]Y[/tex] ~ Bi ( n , p )

Where ''n'' is the number of tests and ''p'' is the success probability.

In our question,

[tex]X[/tex] ~ Bi ( n , p ) ⇒ [tex]X[/tex] ~ Bi ( 10 , 0.49 )

We can think that asking to each of the graduate is our test and whose success probability is p = 0.49

The probability function for [tex]X[/tex] is :

[tex]p_{X}(x)=P(X=x)=\left(\begin{array}{c}n&x\end{array}\right)p^{x}(1-p)^{n-x}[/tex] ; [tex]x=0,1,...,n.[/tex]

Where [tex]\left(\begin{array}{c}n&x\end{array}\right)[/tex] is the combinatorial number defined as [tex]\left(\begin{array}{c}n&x\end{array}\right)=\frac{n!}{x!(n-x)!}[/tex]

For this question, the probability function is :

[tex]P(X=x)=\left(\begin{array}{c}10&x\end{array}\right)(0.49)^{x}(1-0.49)^{10-x}[/tex] ; [tex]x=0,1,...,10[/tex]

We need to calculate [tex]P(X=4)[/tex] ⇒

[tex]P(X=4)=\left(\begin{array}{c}10&4\end{array}\right)(0.49)^{4}(1-0.49)^{6}=0.2130[/tex]

The probability is [tex]0.2130[/tex]

Seismic waves are waves of energy that are generated by earthquakes and travel through the Earth's crust. Scientists can use these waves to measure and locate earthquakes.

To measure an earthquake, scientists use seismographs, which are instruments that detect and record seismic waves. The seismograph produces a graph of the seismic waves, known as a seismogram, which can be used to measure the magnitude of the earthquake. The magnitude is a measure of the energy released by the earthquake and it is commonly measured by the Richter Scale.

To locate an earthquake, scientists use a technique called triangulation. This involves measuring the time it takes for seismic waves to travel from the earthquake to different seismograph stations. By measuring the time difference, scientists can calculate the distance between the earthquake and each station. By using the distance information from three or more seismograph stations, scientists can triangulate the location of the earthquake.

Another way scientists can locate an earthquake is by using seismograms to determine the depth of the earthquake. Seismic waves travel faster through solid rock than through soil or soft rock, so scientists can use the difference in arrival time of different types of seismic waves to determine the depth of the earthquake.

In conclusion, scientists use seismic waves to measure and locate earthquakes by analyzing the data generated by seismographs to estimate the magnitude, and measuring the time it takes for seismic waves to travel from the earthquake to different seismograph stations to estimate the location and depth of the earthquake.

Answer:

B. However, child psychologist David Foulkes argues that babies use REM sleep for other purposes.

Explanation:

Answer B

Correct. In the second paragraph, the claim is that because babies spend so much of their time in REM sleep, the stage at which dreaming occurs for adults, they most likely experience dreams. The third paragraph refutes that claim, starting with this sentence that references an expert in the field who argues that babies use their REM sleep time for “other purposes.”

The sentence which best accomplishes the writer’s goal is: B. However, child psychologist David Foulkes argues that babies use REM sleep for other purposes.

A claim can be defined as a sentence (statement) that is used by a writer to prove, substantiate or support an argument. This ultimately implies that, it ​is an assertive sentence (statement) that is expressed by a writer to prove that an argument is either true or real.

Based on the excerpt, the sentence which best accomplishes the writer’s goal is adding "However, child psychologist David Foulkes is of the strong opinion that babies use REM sleep for other purposes."

Explanation:

Differentiation

Integration

Integration Rule [Fundamental Theorem of Calculus 2]:
[tex]\displaystyle \frac{d}{dx}[\int\limits^x_a {f(t)} \, dt] = f(x)[/tex]

Let's organize what is given to us from the problem.

We are given an initial condition: f(0) = 5.420

We are given a derivative:
[tex]\displaystyle f'(x) = \sqrt{\sin^2 x + x}[/tex]

We are asked to find f(2π).

We can first formulate a rough function using integration rules, namely the Fundamental Theorem of Calculus (2nd part):

[tex]\displaystyle f(x) = \int \limits^{x}_{a} f(t) \, dt + C_0[/tex]

where f(t) is a derivative function and C₀ is an initial condition.

Now that we have a "baseline formula", we can substitute in our f(t) derivative function, our limits, and our initial condition:

[tex]\displaystyle f'(x) = \sqrt{\sin^2 x + x} \Rightarrow f(t) = \sqrt{\sin^2 t + t}[/tex]

[tex]\displaystyle \begin{aligned}f(x) & = \int \limits^{x}_{a} f(t) \, dt + C_0 \\& = \int \limits^{x}_{0} \sqrt{\sin^2 t + t} \, dt + f(0) \\& = \boxed{ \int \limits^{x}_{0} \sqrt{\sin^2 t + t} \, dt + 5.420 } \\\end{aligned}[/tex]

∴ our general function is equal to:
[tex]\displaystyle \boxed{ f(x) = \int \limits^{x}_{0} \sqrt{\sin^2 t + t} \, dt + 5.420 }[/tex]

*Note:

There isn't an antiderivative for the general function, so you will have to input the integral into a calculator.

In order to find the value of f at 2π, we substitute x = 2π into our general function:

[tex]\displaystyle \begin{aligned}f(2 \pi) & = \int \limits^{2 \pi}_{0} \sqrt{\sin^2 t + t} \, dt + 5.420 \\& = 11.44863485704886 + 5.420 \\& = 16.868634857 \\& \approx \boxed{ 16.868 } \\\end{aligned}[/tex]

∴  [tex]\displaystyle \boxed{ f(2 \pi) \approx 16.868 }[/tex]

∴ the value of f(2π) is approximately 16.868.

Explanation:

The rapidly increasing use of coal in the late nineteenth century required hundreds of thousands of workers to dig that coal out of the ground, sort and load it into railroad cars, and ship it to the urban and industrial centers that consumed it. Most coalfields were sparsely populated compared to the cities they supplied. Workers had to be recruited and lured to the coal camps. Company representatives traveled across the agricultural south, recruiting Black workers from former plantation areas as a new wave of white violence followed the collapse of Reconstruction. Recruiters also went to struggling towns in Southern and Eastern Europe, paying voyage fares for men who promised to work in the coal mines on arrival. By the turn of the twentieth century, close to half a million workers—mostly men and boys, but also some women in smaller, family mines—toiled in the American coalfields.The reality of the coal camp often looked very different from what had been promised. Pay was low, and the company, which often owned miners’ housing and ran the supply store, frequently controlled their cost of living. Miners were paid by the ton, and conflicts frequently arose over the process of weighing the coal. The industry’s cyclical nature meant that mining employment also could be irregular and precarious. Coal camp living conditions were often squalid, with social life dominated by the company and basic freedoms of speech, movement, and assembly restricted by private mine guards and company-paid sheriffs.Mining coal was incredibly dangerous work. During the industrial coal boom between 1880 and 1923, more than 70,000 miners died on the job. Many more perished from occupational diseases, but weren’t tallied in official statistics. Miners were crushed to death in roof collapses, killed by gas explosions and by machinery, and more. In the first decade of the twentieth century, three major mine disasters—one each in Utah, West Virginia, and Pennsylvania—killed 201, 362 and 239 miners respectively. The West Virginia and Pennsylvania disasters occurred within two weeks of each other in 1907, during the winter period that miners called “explosion season” because the dry air amplified the dangers from methane and coal dust. More common were deadly and frequent disasters that took miners’ lives in ones and twos, but never made headlines. As urban energy intensification made cities safer, healthier, and more convenient during the Progressive Era, the everyday violence of the energy system was largely hidden from view in rural mining communities.

Explanation:

The other product that is produced when hydrochloric acid (HCl) is added to limestone (calcium carbonate) is calcium chloride (CaCl2).

The balanced chemical equation for this reaction is:

CaCO3(s) + 2HCl(aq) -> CaCl2(aq) + H2O(l) + CO2(g)

In this equation, the solid limestone (CaCO3) reacts with the aqueous hydrochloric acid (HCl) to produce calcium chloride (CaCl2) dissolved in water, water (H2O) and carbon dioxide (CO2) as a gas. On a molar basis the reaction is 1:1 between the Calcium carbonate and hydrochloric acid which results in the balanced equation.

It's worth noting that this reaction is an example of an acid-base reaction, where the hydrochloric acid (HCl) acts as the acid, and the limestone (CaCO3) acts as the base. The acid donates a proton (H+) to the base, resulting in the formation of the products.

Answer:

the gravity keeps a huge distance between them

Most stars are not destroyed in a galaxy collision as galaxies are mostly empty space. The correct option is D.

A galaxy is a massive cloud of gas and dust, as well as billions of stars and their solar systems.

Gravity holds a galaxy together. In the center of our galaxy, the Milky Way, there is also a supermassive black hole. When you look up at the stars at night, you can see other stars in the Milky Way.

If we used today's best technology to make the most basic estimate, we'd say there are 170 billion galaxies in our Universe.

Although the procedure of a galaxy collision reorganizes the stars into new structures (first tidal tails, then elliptical galaxies), because the space between stars is so large, it is extremely unlikely that even a single star collided with another star during this process.

Thus, the correct option is D.
