\(y=\frac{1}{5}x-\frac{7}{5}\)EXPLANATION
We want to find the equation of the line that is perpendicular to the given line:
\(y=-5x+1\)First, we have to find the slope of the line. The slope of a line perpendicular to a given line is the negative inverse of the slope of the line.
The slope of the given line is -5.
Therefore, the slope of the perpendicular line is:
\(\begin{gathered} m=-(\frac{1}{-5}) \\ m=\frac{1}{5} \end{gathered}\)To find the equation of the line, we have to apply the point-slope method:
\(y-y_1=m(x-x_1)\)where (x1, y1) is the point the line passes through.
Therefore, the equation of the line is:
\(\begin{gathered} y-(-1)=\frac{1}{5}(x-2) \\ y+1=\frac{1}{5}x-\frac{2}{5} \\ y=\frac{1}{5}x-\frac{2}{5}-1 \\ y=\frac{1}{5}x-\frac{7}{5} \end{gathered}\)That is the equation of the line.
In a diagram, ∠A and ∠B are vertical angles, and ∠B is a complementary angle with ∠C. If ∠A=22°, write an equation that you can use to solve for ∠C.
Answer:
22° + m<C = 90°
Step-by-step explanation:
Pre-SolvingWe are given that <A (which is equal to 22°) and <B are vertical angles, and that <B is complementary to <C.
We want to write an equation that will help us solve <C.
SolvingRecall that vertical angles are congruent by vertical angles theorem.
This means that <A ≅ <B; it also means that the measure of <B is also 22°.
Also recall that complementary angles add up to 90°.
This means that m<B + m<C = 90°.
Since we deduced that m<B is 22°, we can substitute that value into the equation.
Hence, an equation that can be used to solve for <C is:
22° + m<C = 90°
Find the x- and y-intercepts of the graph of x+10y=20
The x- and y-intercepts of the graph of x+10y = 20 include the following:
x-intercept = (20, 0).
y-intercept = (0, 2).
What is the x-intercept?In Mathematics, the x-intercept is also referred to as horizontal intercept and the x-intercept of the graph of any function simply refers to the point at which the graph of a function crosses or touches the x-coordinate (x-axis) and the y-value or value of "y" is equal to zero (0).
x + 10y = 20
x + 10(0) = 20
x = 20
Therefore, the x-intercept is (20, 0).
For the y-intercept of the function, we have:
x + 10y = 20
0 + 10y = 20
y = 20/10
y = 2
Therefore, the y-intercept is (0, 2).

Triangles
• If one side of a triangular piece of yard area is roughly one-third the perimeter,
the second side is roughly one-fifth the perimeter, and the third side is 7yards,
what is the perimeter of the triangle?
Answer:
15m
Step-by-step explanation:
The third side = (2/3 - 1/5) of the perimeter = 7/15 of the perimeter = 7m
The first side is 1/3 (=5/15) of the perimeter = 5m
The second side is then 3m ( or 1/5=3/15 of the perimeter).
The triangle perimeter is 15 meters (=7 m+5m+3m)
Reuben made a shirt using 7/8yards of red fabric and 1/4yards of yellow fabric. How many more yards of red fabric did Reuben use?
Answer and Step-by-step explanation:
To find out how many more yards of red fabric Reuben used, we need to subtract the amount of yellow fabric from the amount of red fabric. Since the two fractions have different denominators, we need to find a common denominator before subtracting them. The least common multiple of 8 and 4 is 8, so we can rewrite both fractions with a denominator of 8:
7/8 - 1/4 = 7/8 - (1/4) * (2/2) = 7/8 - 2/8 = (7 - 2)/8 = 5/8
So, Reuben used 5/8 yards more red fabric than yellow fabric.

A community would like to add a brick paver border around their swimming pool. They created the following image to represent the pool with the border. A large rectangle with a length of 48 feet and a width of 28 feet. Inside of it is another rectangle with a length of 32 feet and a width of 12 feet. Part A: Find the total area of the brick paver border that surrounds the 12 ft by 32 ft pool. Show your work. (2 points) Part B: If brick pavers cost $8 per square foot, what is the total cost of the brick pavers needed for this project? Explain. (2 points)
Part A: The total area of the brick paver border is \(960\) square feet.
Part B: The total cost of the brick pavers needed for this project is $\(7,680\).
Part A: To find the total area of the brick paver border, we need to subtract the area of the pool from the area of the larger rectangle. The area of the pool is \(32\) feet multiplied by 12 feet, which is equal to \(384\)square feet.
The area of the larger rectangle is \(48\) feet multiplied by \(28\) feet, which is equal to \(1,344\) square feet. Therefore, the area of the brick paver border is \(1,344\) square feet minus \(384\) square feet, which equals \(960\) square feet.
Part B: If brick pavers cost $\(8\)per square foot, we can calculate the total cost by multiplying the cost per square foot by the total area of the brick paver border. The total area of the brick paver border is \(960\) square feet, and the cost per square foot is $\(8\).
Therefore, the total cost of the brick pavers needed for this project is $\(8\)multiplied by \(960\) square feet, which equals $\(7,680\).
Note: The calculations provided assume that the border consists of a single layer of brick pavers.

Answer:
\(\frac{p^2-25}{p^2-10p+25}\)
We can factorise the numerator with the difference of squares formula:\(x^2-y^2=(x+y)(x-y)\)
-----------------------------
\(\frac{p^2-5^2}{p^2-10p+25} =\frac{(p+5)(p-5)}{p^2-10p+25}\)
Now we can factorise the denominator:
\(\frac{(p+5)(p-5)}{p^2-10p+25} =\frac{(p+5)(p-5)}{(p-5)^2}\)
\(\frac{(p+5)(p-5)}{(p-5)^2} =\frac{(p+5)(p-5)}{(p-5)(p-5)}\)
Cancel out the common factor of (p-5):
\(\frac{(p+5)(p-5)}{(p-5)(p-5)} =\frac{(p+5)}{(p-5)}\)

Which principle of government was supported most by the Anti-Federalists?
Answer:
Anti-Federalism
From Wikipedia, the free encyclopedia
Jump to navigationJump to search
For the faction opposed to the policies of U.S. President George Washington, see the Anti-Administration party.
The Articles of Confederation, the predecessor to the U.S. Constitution and drafted from Anti-Federalist principles
Anti-Federalism was a late-18th century movement that opposed the creation of a stronger U.S. federal government and which later opposed the ratification of the 1787 Constitution. The previous constitution called the Articles of Confederation and Perpetual Union, gave state governments more authority. Led by Patrick Henry of Virginia, Anti-Federalists worried, among other things, that the position of president, then a novelty, might evolve into a monarchy. Though the Constitution was ratified and supplanted the Articles of Confederation, Anti-Federalist influence helped lead to the passage of the United States Bill of Rights.
Contents
Major points
They believed the Constitution needed a Bill of Rights.
They believed the Constitution created a presidency so powerful that it would become a monarchy.
They believed the Constitution did too little with the courts and would create an out-of-control judiciary.
They believed that the national government would be too far away from the people and thus unresponsive to the needs of localities.
They believed the Constitution would abrogate, at least in part, the power of the states.[1]
History
During the American Revolution and its immediate aftermath, the term federal was applied to any person who supported the colonial union and the government formed under the Articles of Confederation. After the war, the group that felt the national government under the Articles was too weak appropriated the name Federalist for themselves. Historian Jackson Turner Main wrote, "to them, the man of 'federal principles' approved of 'federal measures,' which meant those that increased the weight and authority or extended the influence of the Confederation Congress."[2]
As the Federalists moved to amend the Articles, eventually leading to the Constitutional Convention, they applied the term anti-federalist to their opposition. The term implied, correctly or not, both opposition to Congress and unpatriotic motives. The Anti-Federalists rejected the term, arguing that they were the true Federalists. In both their correspondence and their local groups, they tried to capture the term. For example, an unknown anti-federalist signed his public correspondence as "A Federal Farmer" and the New York committee opposing the Constitution was called the "Federal Republican Committee." However, the Federalists carried the day and the name Anti-Federalists forever stuck.[2]
The Anti-Federalists were composed of diverse elements, including those opposed to the Constitution because they thought that a stronger government threatened the sovereignty and prestige of the states, localities, or individuals; those that saw in the proposed government a new centralized, disguised "monarchic" power that would only replace the cast-off despotism of Great Britain;[3] and those who simply feared that the new government threatened their liberties. Some of the opposition believed that the central government under the Articles of Confederation was sufficient. Still, others believed that while the national government under the Articles was too weak, the national government under the Constitution would be too strong. Another complaint of the Anti-Federalists was that the Constitution provided for a centralized rather than federal government (and in The Federalist Papers, James Madison admits that the new Constitution has the characteristics of both a centralized and federal form of the government) and that a truly federal form of government was a leaguing of states as under the Articles of Confederation.
During the period of debate over the ratification of the Constitution, numerous independent local speeches and articles were published all across the country. Initially, many of the articles in opposition were written under pseudonyms, such as "Brutus" (likely Melancton Smith),[4] "Centinel" (likely Samuel Bryan), and "Federal Farmer." Eventually, famous revolutionary figures such as Patrick Henry came out publicly against the Constitution. They argued that the strong national government proposed by the Federalists was a threat to the rights of individuals and that the president would become a king. They objected to the federal court system created by the proposed constitution. This produced a phenomenal body of political writing; the best and most influential of these articles and speeches were gathered by historians into a collection known as the Anti-Federalist Papers in allusion to the Federalist Papers.

please help !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
90°
Step-by-step explanation:
Through point O draw a ray on left side of O which is || to AB & CD and take any point P on it.
Therefore,
∠ABO + ∠BOP = 180° (by interior angle Postulate)
118° + ∠BOP = 180°
∠BOP = 180° - 118°
∠BOP = 62°.... (1)
Since, ∠BOP + ∠POD = ∠BOD
Therefore, 62° + ∠POD = 152°
∠POD = 152° - 62°
∠POD = 90°.....(2)
∠POD + ∠ODC = 180° (by interior angle Postulate)
90° + ∠ODC = 180°
∠ODC = 180° - 90°

The force vector F in terms of i and j, considering it's magnitude and angle, is represented by:
\(V = 11\sqrt{2}i + 11\sqrt{2}j\)
How can a vector be represented in i and j notation?Given a magnitude M and angle \(\theta\), the a vector V can be represented as follows:
\(V = M\sin{\theta}i + M\cos{\theta}j\)
In this problem, we have that the parameters are as follows:
\(M = 22, \theta = 45^\circ\)
Hence:
\(V = 22\sin{45^\circ}i + 22\cos{45^\circ}j\)
\(V = 22\frac{\sqrt{2}}{2}i + 22\frac{\sqrt{2}}{2}j\)
\(V = 11\sqrt{2}i + 11\sqrt{2}j\)
