How can I collect primary data for the environmental impacts of urban development in a local area?
Find the area of the shape shown below.
Answer: [tex]42 units^{2}[/tex]
Explanation:
We can divide this figure in a rectangle with base [tex]b=1 unit[/tex] and height [tex]h=12 units[/tex]; and a right triangle with base [tex]B=5 units[/tex] and height [tex]H=12 units[/tex].
Now, the total area [tex]A[/tex] of the figure will be the area of the rectangle [tex]A_{rectangle}[/tex] plus the area of the triangle [tex]A_{triangle}[/tex]:
[tex]A=A_{rectangle}+A_{triangle}[/tex]
Where:
[tex]A_{rectangle}=(b)(h)=(1 unit)(12 units)=12 units^{2}[/tex]
[tex]A_{triangle}=\frac{(B)(H)}{2}=\frac{(5 units)(12 units)}{2}=30 units^{2}[/tex]
Then:
[tex]A=12 units^{2}+30 units^{2}[/tex]
[tex]A=42 units^{2}[/tex] This is the area of the figure
Answer: 42units
Explanation: first skinny rectangle 12x1 then move on to triangle 12x5 it’s a triangle so divide 60 my 2 then 30+ 12= 42

Explain how and why imperialism and the alliance systems both contributed to the outbreak of ww1
Imperialism and alliances were significant factors in causing World War I.
Imperialism and the alliance systems were major contributors to the outbreak of World War I. Imperialism created competition among nations for colonies and resources, leading to tensions and rivalries. This desire for more colonies, particularly by Germany, clashed with existing empires like the British Empire, fueling conflict. Meanwhile, the system of alliances created a domino effect - when one country was attacked, its allies were drawn in, escalating conflicts beyond local disputes.
1. What is the main cause of wind?
Answer:
Wind is caused by differences in the atmospheric pressure. When a difference in atmospheric pressure exists, air moves from the higher to the lower pressure area, resulting in winds of various speeds. On a rotating planet, air will also be deflected by the Coriolis effect, except exactly on the equator.

What’s the economic process where a country buys raw materials, processes them and sells them back to where they bought them from
The process that is described is called Mercantilism.
Explanation:
Mercantilism is an economic process that was in use during the imperialist period, mostly by the European imperial powers. This economic process was based on a triangle, where the mother country takes raw materials from the colony, take them back and manufacture them, and return them and sell them on the market from where the raw materials were taken. Basically, the imperialist were taking cheap or free materials, make products of them, and sell them for higher prices to the same people from which they took the materials. The process was motivated by the industrialization.
This process was taking place on pretty much all continents, except for Antarctica, with Africa and South Asia being the most exploited in it. The Mercantilism brought in enormous amounts of wealth to the European imperialist, which in turn contributed to even further development and increase of power on the global scene. The regions that were exploited still suffer a lot because of it.

The process of buying raw materials, processing them into goods and selling them is known as the production function, which is a key component of the value chain in business.
The economic process where a country buys raw materials, processes them, and then sells the processed products back to the source of the raw materials is known as the production function. This involves the transformation of raw materials into goods and services that consumers use. The value chain describes the series of steps a company takes to add value to raw materials. This includes acquiring raw materials, transforming them into usable materials, assembly into finished products, distribution, and the final retail sale. When a country exports these value-added goods instead of just the raw materials, it benefits economically as processed goods usually command a higher price than raw materials. Examples can be seen in Asian economies' growth, where exporting electronics and automotive products has been more profitable than exporting unprocessed materials.

The freedom of association refers to the right of people to voluntarily come together and express shared interests or viewpoints, a right protected by the Constitution. The provided example of forming a group on a college campus to support a political candidate is a representation of this freedom, unlike an individual buying a gym membership.
Explanation:The freedom of association refers to the right of individuals to come together and collectively express, promote, pursue and defend common interests. This freedom is protected by the First Amendment in the United States Constitution.
Based on the options given in the question, the situation that would be considered an example of the freedom of association would be Option B: A group forms on a college campus to support a particular political candidate. This is because this option involves individuals coming together on a voluntary basis to express a shared political viewpoint.
In contrast, Option A, an individual buying a gym membership, would not be considered an example of the freedom of association as this action does not reflect the collective action or shared interests that are inherent to the definition of this freedom.

Explanation:
Apex
Radio and television station markets and Accents used in speech are some reasons to consider Boston and New York as being in separate regions. Thus, option 'A' and 'C' is the correct option.
How does Media market work?A media market, also known as a broadcast market, media region, designated market area (DMA), television market area, or simply market, is a geographic area where residents have access to the same (or comparable) television and radio programming, as well as other media outlets like newspapers and the internet. Despite the fact that rural areas with few important population centers can also be referred to as marketplaces, they may coincide or overlap with one or more urban areas.
On the other hand, very big metropolitan districts can occasionally be separated into several sections. Market regions may cross across, making it possible for consumers who live on the outskirts of one media market to access material from other surrounding markets. They are often utilized in audience measures, which are compiled in the US by Nielsen Media Research.

I recreated the coordinate plane with your points and draw the attached image to answer your question with complete explanation.
Here is every question each with its answer and explanation.
1. What are the coordinates of point A?
A. (-4,3)
B. (3,-4)
C. (-4,4)
D. (-3,4)
Answer:
A. (-4,3)Explanation:
In an ordered pair (a,b), the first number, a, is the x-coordinate. Thus, you must imaginally draw a vertical line from the point A to the x-axis and read the corresponding mark. In this case, that mark is to the left of the coordinate origin of the plane, thus it is negative. The value that you will read is -4.
In the same ordered pair (a,b), the second number, b, is the y-coordinate. Thus, you must must imaginally draw a horizontal line from the point A to the y-axis and read the corresponding mark. In this case, that mark above the coordinate origin of the plane, thus it is positive. The value you will read is 3.
Hence, the coordinates of the point A are (4, -3), option A.
2. What are the coordinates of Point B?
A. (1,3)
B. (3,1)
C. (-3,1)
D. (1, -3)
Answer:
B (3,1)Explanation:
To find the x-coordinate go, vertically down from the point B until you find the x-axis. Read the mark on the axis. It is to the right of the coordinate origin, thus it is positive. Tha value is 3. Thus, the first number of your ordered pair is 3.
To find the y-coordinate, go horizontally to the left until you find the y-axis. That is above the coordnate origin, thus the coordinate is positive. The corresponding mark that you read is 1. Therefore, the second number of your ordered pair is 4.
Therefore, the coordinates of point B are (3, 1): the option B, from the choices.
3. Which point is located at (4,-5)?
A. A
B. B
C. C
D. D
Answer:
C. CExplanation:
Now the work is different. You must start on the axis and then find the point.
The first number of the ordered pair (4, -5) is the x-coordinate and the second number is the y-coordinate.
Then, draw a vertical line through the mark x = 4 (on the x-axis) and a horizontal line through the mark y = - 5 (on the y-axis).
The intersection of those two lines is the point (4, -5) that is the point C on the diagram.
4. In which quadrant is Point C?
A. Quadrant I
B. Quadrant II
C. Quadrant III
D. Quadrant IV
Answer:
Quadrant IIIExplanation
The two perpendicular lines determine 4 sections of the coordinate plane. Those sections are named quadrants are numbered in the counterclockwise.
Quadrant I: upper right secion.Quadrant II: upper left sectionQuadrant III: bottom left sectionQuadrant IV: bottom right sectionThe point C is in the bottom left secion, thus it is quadrant III,which is the option C.
5. If the coordinates of a point have the same sign, which quadrant(s) could the point be in?
A. Quadrants I and II
B. Quadrants I and III
C. Quadrants III
D. Quadrants IV
Answer:
B. Quadrants I and IIIExplanation:
By the construction, the quadrant I contains the points with positive x-coordinates and positive y-coordinates. Thus, the coordinates of a point on the quadrant I are both equal (positive).
Also, the quadrant III contains the points with negative x-coordinates and negative y-coordinates. Thus, the coordinates of a point on the quadrant III are both equal (negative).
Therefore, both quadrants I and III could be the quadrants where the point whose coordinates have the same sign is. Thus, the option B. Quadrants I and III is true.
On the other hand, the other two quadrants can only contain points whose coordinates have opposite signs.
Question 3 (1 point)
a nonconformity is a "hiatus" in time between rock layers. This is usually shown by uneven meeting point between 2 layers. Why does this
occur?
igneous intrusion
weathering and erosion of the old layer
lithification of a new layer
heat and pressure on the old layer
This occur due to "weathering and erosion of the old layer".
Answer: Option B
Explanation:
A submerged erosional or non-depositional surface that isolates masses of two rock or strata of varying ages, showcasing the deposition of sediments was not permanent is called as an Uniformity. The older layer was usually subjected to erosion for a time interval before the younger layer was deposited but the expression is used to characterize any break is the "sedimentary geological record".
The local record for such an interval is incomplete and geologists need to use other information to uncover that aspect of that area's geological history. The unrepresented geological time period is called a hiatus. It's a relative dating kind of.
