Answer:
x² - x + 1
Explanation:
Given:
r(x) = -x² + 3x
s(x) = 2x + 1
Required:
(s - r)(x)
Solution:
(s - r)(x) = s(x) - r(x)
Substitute
(s - r)(x) = (2x + 1) - (-x² + 3x)
Apply distribution property by multiply every term in the bracket by -1
(s - r)(x) = 2x + 1 + x² - 3x (recall: - × - = +; - × + = -)
Add like terms
(s - r)(x) = 2x - 3x + 1 + x²
(s - r)(x) = -x + 1 + x²
Rewrite in standard form
(s - r)(x) = x² - x + 1
Why do scientists use Punnett squares? (Site 1)
Answer:
It helps to show what genotype/alleles will be passed down to an offspring during breeding.
it's a diagram so it's a visual explanation to help biologists understand the genotype that's passed down
Answer:
Scientists use Punnett squares to show what genotype/alleles will be passed down to an offspring during breeding. It's a diagram so it's a visual explanation to help biologists understand the genotype that's passed down. The Punnett rectangular is a rectangular diagram this is used to expect the genotypes of a specific go or breeding experiment. The presence of distinct alleles at a specific gene locus. A heterozygous genotype can also additionally encompass one everyday allele and one mutated allele or distinct mutated alleles (compound heterozygote). It is called after Reginald C. Punnett, who devised the method in 1905. The Punnett is utilized by biologists to decide the opportunity of an offspring having a specific genotype. A Punnett Square is a beneficial device that facilitates to expect the versions and chances that could come from go breeding.

I am going into freshman geometry next year. Does anyone have any tips for me? Anything I should do before going into it or things to know? All advice is appreciated
consider the following. the parent function is f(x)=3^x.
partA- IF g(x)=f(x)+k whats the value of k?
part B- if h(x)=f(x+k) whats the values of k?
partC- write the function of G(x) and H(x)
Answer:
Part A;
k = -1
Part B
k = -4
Part C
g(x) = 3ˣ - 1
h(x) = [tex]3^{x - 4}[/tex]
Explanation:
The parent function of the graph, is f(x) = 3ˣ
Part A;
g(x) = f(x) + k
When x = 0, f(x) = 3⁰ = 1
g(x) = f(x) + k = [tex]3 ^{x}[/tex] + k
Therefore;
When x = 0, g(0) = f(0) + k = [tex]3 ^{0}[/tex] + k = k
From the graph, g(0) = -1, therefore;
g(0) = -1 = k
k = -1
Part B
h(x) = f(x + k)
When x = 4, h(4) = f(4 + k) = [tex]3 ^{(4 + k)}[/tex]
From the graph, h(4) = 1, therefore;
h(4) = 1 = [tex]3 ^{(4 + k)}[/tex]
Therefore, we get;
ln(1) = (4 + k)·ln(3)
4 + k = ln(1)/ln(3) = 0
k = 0 - 4 = -4
k = -4
Part C
g(x) = f(x) + k
f(x) = 3ˣ, and k = -1
Therefore;
g(x) = 3ˣ - 1
h(x) = f(x + k)
f(x) = 3ˣ, and k = -4
Therefore;
h(x) = [tex]3^{x - 4}[/tex]
A)One way in which the author's point of view is reflected in his description of United States actions against Cuba
Answer:
The author's point of view is reflected in this phrase; "..., in the near future, the United States using the pretext of an allegedly growing threat to the Western Hemisphere, will embark on a long process of increasing the pressure on governments of the Latin American countries to work out additional threats against Cuba."
Explanation:
The author's perspective is seen in his use of words like "pretext," and "allegedly". The author is thus saying that the United States is not straightforward, or completely honest in the claims of a threat to the Western Hemisphere. This phrase also shows that the author believes that the United States was being unnecessarily hard on the Cuban nation by threatening them.
We can sense that the author of the text favors Cuba as against the United States. In order to determine the author's perspective, careful attention ought to be given to certain key words in the text.

“Hope” is the Thing with Feathers
by Emily Dickinson
Hope is the thing with feathers
That perches in the soul,
And sings the tune without the words,
And never stops at all,
And sweetest in the gale is heard;
And sore must be the storm
That could abash the little bird
That kept so many warm.
I've heard it in the chillest land,
And on the strangest sea;
Yet, never, in extremity,
It asked a crumb of me.
Answer:
optimistic

Study the political cartoon.
A political cartoon shows a man on a wine barrel holding a cup in one hand and black flag in the other. There is a snake curled around the cup. On the barrel are listed different types of alcohol. In the background, groups of people are line up to drink. Some people are falling down with bottles in their hand. In the foreground a woman is weeping. Caption reads 60,000 annually in the states.
Which movement does this political cartoon represent?
religious reform
suffrage
temperance
voting rights
Answer: Temperance
Explanation:
In the 19th century, the Temperance movement gained a lot of steam in the United States and culminated with the Prohibition of Alcohol from 1920 to 1933.
The Temperance movement was founded by those who believed that alcohol was killing nations as people became intoxicated and got into all manner of social ills as well as it having negative effects on their social, professional and family lives.
The picture described above is trying to link alcohol to evil with the black flag and the snake around the cup meant to symbolize that. The people falling are intoxicated and the woman crying is meant to show the negative effects alcohol had on families.

What is the difference between the U.S. system of government and Great Britain’s parliamentary system?
Answer:
While the president is the head of state as well as head of government in the United States, that office does not have the same power as the British Prime Minister, which is effectively an elected dictator. Further, while Congress makes the laws in the United States, Parliament is essentially the entire government.
