Annotate the selected reading from Narrative of the Life of Frederick Douglass chapter 6. Write a short journal response discuss
Vilka [71]

Answer and Explanation:

Notes: Slavery allows it to be so harmful that it changes even the most kind people, making them mean. Education empowers the oppressed. Education is a powerful weapon for blacks. Deprivation can be used as an incentive. Nobody liked to be called an oppressor, even though it was.

I decided to take notes on the most important themes exposed by Douglass. These themes were discovered by reading chapter 6 and by interpreting why Douglass decided to include these moments of his life in his narrative.

The first theme that I noticed is that slavery was widespread and prejudicial to everyone, even for the arms. Slavery placed cruelty in the hearts of white people and made them lose their kindness and kindness by becoming cruel and unworthy. I also noticed that white people were very afraid to allow blacks to have access to education. This is because education allowed the critical thinking that would give blacks the power to fight against the system that oppressed them.

Douglass was deprived of studying, but this deprivation motivated him to strive and receive an education that would make big differences in his life. Last but not least, we can see that the whites knew that the violence of slavery was incorrect, since they did not want them to know that they were extremely violent and oppressive to the slaves they owned.

The author uses several rhetorical strategies that range from personal statements, which increase our empathy for him, to logical and correct statements that show us how that whole slave system worked and how it was manipulated to last. This all causes an extension of what we know about slavery.

Solve the following systems of 3-variable linear equations.​
Zina [86]

Answer:

x = 9/25, y = 7/25, z = 4/25

Explanation:

step 1: solve for y in first equation to use substitution

y = -2x + 1

step 2: insert into second equation to eliminate y variable and work with two variables

3(-2x+1) + z = 1 (now distribute)

-6x + 3 + z = 1 (bring over the -3)

-6x + z = -2

step 3: now left with -6x + z = -2 and x + 4z = 1, so eliminate z

-6x + z = -2 (multiply by 4)

4(-6x + z = -2)

-24x + 4z = -8

-

x + 4z = 1 (brought down third equation)

-25x = -9

x = 9/25

then just plug in x into the third equation to solve for z, followed by plugging it into the first equation to solve for y. you should end with y = 7/25 and z = 4/25

Is it true that the courts are only interested in legal and constitutional questions?
CaHeK987 [17]
Mainly yes, but some courts feel as if the calling for the case if for something that happened that was illegal, than the judges/courts feel more justified when explaining what that person did wrong in his or her calling.

What is the total surface area of the figure below?
erica [24]

\bold{\huge{\pink{\underline{ Solution }}}}

<h3><u>Given </u><u>:</u><u>-</u></h3>

  • <u>We </u><u>have </u><u>given </u><u>one </u><u>irregular </u><u>figure </u><u>which </u><u>is </u><u>composed </u><u>2</u><u> </u><u>triangle's </u><u>and </u><u>3</u><u> </u><u>rectangles </u>
  • <u>The </u><u>height </u><u>and </u><u>base </u><u>of </u><u>the </u><u>triangles</u><u> </u><u>is </u><u>6cm </u><u>and </u><u>7</u><u> </u><u>cm</u><u> </u><u>each </u>
  • <u>The </u><u>length </u><u>and </u><u>breath </u><u>of </u><u>the </u><u>rectangles</u><u> </u><u>is </u><u>1</u><u>3</u><u>.</u><u>1</u><u> </u><u>cm </u><u>and </u><u>7cm </u><u>each </u>

<h3><u>To </u><u>Find </u><u>:</u><u>-</u></h3>

  • <u>We </u><u>have </u><u>to </u><u>find </u><u>the </u><u>total </u><u>surface </u><u>area </u><u>of </u><u>the </u><u>given </u><u>figure</u><u>? </u>

<h3><u>Let's </u><u>Begin </u><u>:</u><u>-</u></h3>

<u>We </u><u>have</u><u>, </u>

  • 2 triangles of height 6 cm and base 7cm each
  • 3 rectangles of length 13.1 cm and 7cm each

<u>Therefore</u><u> </u><u>,</u>

<u>We </u><u>know </u><u>that</u><u>, </u>

Area of triangle

\bold{=}{\bold{\pink{\dfrac{1}{2}}}}{\bold{\pink{ × Base × Height }}}

<u>Subsitute </u><u>the </u><u>required </u><u>values</u><u>, </u>

<u>Area </u><u>of </u><u>1</u><u> </u><u>triangle </u>

\sf{=}{\sf{\dfrac{1}{2}}}{\sf{ × 7 × 6 }}

\sf{ = 7 × 3 }

\sf{ = 21 cm²}

<h3><u>Therefore</u><u>, </u></h3>

<u>Area </u><u>of </u><u>2</u><u> </u><u>triangle's </u>

\sf{ = 2 × ( Area\:of\:1\:traingle) }

\sf{ = 2 × 21 }

\sf{ = 42 cm² }

Thus, The area of 2 triangles is 42 cm²

<h3><u>Now</u><u>, </u></h3>

<u>We </u><u>know </u><u>that</u><u>, </u>

Area of rectangle

\bold{\red{ = Length × Breath }}

<u>Subsitute </u><u>the </u><u>required </u><u>values</u><u>, </u>

Area of 1 rectangle

\sf{ = 13.1 × 7 }

\sf{ = 91.7 cm² }

<h3><u>Therefore</u><u>,</u></h3>

<u>Area </u><u>of </u><u>3</u><u> </u><u>rectangles </u>

\sf{ = 3 ×( Area\:of\:1\:rectangle)  }

\sf{ = 3 × 91.7 }

\sf{ = 275.1 cm² }

Thus, The area of 3 rectangle is 275.1 cm²

<h3><u>So</u><u>, </u></h3>

Total area of the given figure

  • = Area of 2 triangles + Area of 3 rectangles

\sf{ = 42 + 275.1 }

\bold{ = 317.1 cm²}

Hence, The total surface area of the given figure is 317.1 cm² .
