Given that point A is the midpoint of line segment ED, where E( -1,9) and A(4,5), what is the location of point D?

Answers

Answer 1

Answer:

D(9, 1)

Explanation:

Since A is the midpoint of ED, then;

A = ([tex]\frac{X_{1}+X_{2} }{2}[/tex], [tex]\frac{Y_{1}+Y_{2} }{2}[/tex])

A(4, 5) ⇒ 4 =  [tex]\frac{X_{1}+X_{2} }{2}[/tex] and 5 = [tex]\frac{Y_{1}+Y_{2} }{2}[/tex]

[tex]\frac{X_{1}+X_{2} }{2}[/tex] = 4

[tex]X_{1}[/tex] + [tex]X_{2}[/tex] = 8

But [tex]X_{1}[/tex] = -1, then;

-1 + [tex]X_{2}[/tex] = 8

[tex]X_{2}[/tex] = 9

[tex]\frac{Y_{1}+Y_{2} }{2}[/tex] = 5

[tex]Y_{1}[/tex] + [tex]Y_{2}[/tex] = 10

But [tex]Y_{1}[/tex] = 9, then;

9 + [tex]Y_{2}[/tex]  = 10

[tex]Y_{2}[/tex]  = 1

Therefore, point D has coordinates (9, 1).

Advantage and Disadvantage of
Conventional and non-conventional source
of energy​

Answers

Answer:

Conventional sources of energy is also called non-renewable sources of energy while non conventional sources of energy is called renewable sources of energy.

An example of conventional energy is coal, crude oil and natural gas. The advantage is the availability and affordability. The disadvantage is the level of air pollutants such as CO2 and CO it releases to the atmosphere which is harmful as it poses a risk of air borne illnesses.

An example of non conventional energy is the sun, wind , water etc. The advantage is that it reduces the risk of air pollution and keeps the environment clean as no toxic substances are being released into the atmosphere when used. The disadvantage is they are expensive and aren’t available all year round.

Uniformitarianism means:________. a. neither the scientific past nor the future can be predicted because physical laws change over time. b. earth's surface, including the oceans and continents, has always been the same and will always remain unchanged. c. geologic processes on Earth all operate at roughly the same speed, which has not changed over time. d. geologic processes that operate today operated in the past at about the same speed.

Answers

Answer:

Uniformitarianism means:

d. geologic processes that operate today operated in the past at about the same speed.

Geologists study present geologic processes, whether they are sudden, like an earthquake, or slow, like the erosion of a river valley, to gain insight into the past. This is known as uniformitarianism.

Thus, option D is correct.

Who made uniformitarianism?

The theory of uniformitarianism was developed by Charles Lyell in the 19th century and is based on the writings of James Hutton. According to this hypothesis, the forces and processes that can be seen at the surface of the earth are the same ones that have sculpted the planet's terrain throughout natural history.

The belief that the same natural laws and processes that govern the universe today and have always governed it in the past and apply to all of it is known as uniformitarianism, also known as the Doctrine of Uniformity or the Uniformitarian Principle. Today, we accept uniformitarianism as genuine and understand that major catastrophes like earthquakes, asteroids, volcanoes, and floods are a regular part of the earth's cycle.

Answers

Answer:

subside

Explanation:

Isostasy is a geographical term which describes the condition of gravitational equilibrium that exists within the Earth's crust and mantle, there by, making the crust stays above a heights that relies on its physical attributes, such as thickness and density.

In Isostasy, its occurrence process involves principles of buoyancy in which an Earth crust apply stress on the less stronger mantle, such that for over a geological time moves laterally in a way that the load is contained by height adjustments.

Hence, Isostasy would suggest that the area at the mountain front, where the thrust emerges, should SUBSIDE over time.

Describe how children are affected by children labour? Please respond me ASAP

Answers

Answer:

The difference between ‘child labour’ and ‘child work’ is that child labour refers to work that is

harmful to children. It is work that is mentally or physically dangerous, work that interferes

with their ability to go to school which can affect their income-earning potential as adults. The

health and wellbeing of child labourers is at risk, and they can end up being trapped in a cycle

of poverty.

There are a number of ways that child labour can affect children, and these can vary

depending on which industry the child is working in. Generally, child labourers can suffer from

long-term health problems due to malnutrition, exposure to chemicals, abuse, injuries,

exhaustion, and psychological harm.

1

 In agriculture, children may be exposed to toxic pesticides or fertilisers. They work with

dangerous blades and tools, and carry heavy loads.

 In mining, children may use poisonous chemicals, face the risk of mine collapse, and

sometimes work with explosives.

 In construction, children may carry heavy loads, work at heights without safety

equipment, and risk injury from dangerous machinery.

 In manufacturing, children may use toxic solvents, perform repetitive tasks in painful

positions, and risk injury from sharp tools.

 In domestic work, children risk abuse, work long hours, and often live in isolation from

their families and friends.

Approximately how far back in time does the fossil record extend? Approximately how far back in time does the fossil record extend? 3.5 billion years 5.0 million years 5.0 billion years 3.5 million years

Answers

Answer:

A : 3.5 billion years ago

Approximately about 3.5 billion years ago the fossil record extend.  The reason the correct option is a.  

According to radiometric dating, Earth formed around 4.5 billion years ago. The oldest fossils, which are found in rocks older than 3.5 billion years (see Precambrian epoch), resemble creatures like bacteria and cyanobacteria (blue-green algae). The so-called Ediacara fauna, which consists of small, soft-bodied wormlike organisms, is where the oldest animal fossils, dating back roughly 700 million years, may be found. In rocks that are around 540 million years old, there are many fossils with mineralized skeletons that belong to several living phyla.

The oldest fossils date back between 3.48 and 4.1 billion years. A geological timescale and the relative ages of various fossils were recognised in the 19th century as a result of the discovery that specific fossils were linked to specific rock strata.

The second option is correct (The Bulge of Africa is in the West, and the Horn is in the East).

During the Soviet Era, the government had a great effect on agriculture. Do you believe that the system of agriculture was subsistence farming or commercial farming, or a combination of the two? Explain.

Answers

Answer:

A combination.

Explanation:

The government mandated that most crops grown under Soviet rule would be given to the gov. to redistribute to people in need; however this caused great hunger and people started to farm on the side for substinence. Now hardcore socialists believe commercial farming is not applicable to government-takeover of crops, but I call it commercial since there was "compensation" to the farmers (not really lol).

During the Soviet Era, the government had a great effect on agriculture. The  believe that the system of agriculture was subsistence farming or commercial farming, or a combination of the two are the limited cultivation of private plots.

What is government?

The term “government” refers to a legal authority or system that is controlled and directed by an office, public sector, country, or state. The government imposed the law. The most common functions of the government are leadership, controlling, maintaining order, commanding, providing public services, and national security.

Agriculture in the Soviet Union was primarily collectivized, with some individual parcels being farmed. The government stipulated that the majority of food harvested under Soviet authority be provided to the government for redistribution to persons in need. Socialists think that government-takeover of crops does not apply to commercial farming.

As a result, the Soviet Era, the government had a great effect on agriculture.
