Answer:
Explanation:
To find the x-intercept of the line passing through point C(5,12) and perpendicular to the line passing through points A(-10,-3) and B(7,14), we first need to find the equation of the line passing through points A and B.
The slope of the line passing through points A and B is:
m = (14 - (-3)) / (7 - (-10))
m = 17 / 17
m = 1
So, the equation of the line passing through points A and B can be written as:
y - (-3) = 1(x - (-10))
y + 3 = x + 10
y = x + 7
The line perpendicular to this line will have a slope of -1 (negative reciprocal of 1).
So, the equation of the line passing through point C(5,12) and perpendicular to the line passing through points A and B can be written as:
y - 12 = -1(x - 5)
y - 12 = -x + 5
y = -x + 17
To find the x-intercept, we can set y = 0 in this equation and solve for x:
0 = -x + 17
x = 17
Therefore, the x-intercept of the line passing through point C(5,12) and perpendicular to the line passing through points A(-10,-3) and B(7,14) is x = 17.
To find the point on which the x-intercept lies, we can substitute x = 17 into the equation of the line passing through points A and B:
y = x + 7
y = 17 + 7
y = 24
So, the point on which the x-intercept lies is (17,24).

How do plants most affect global temperature?
A
Plants capture carbon dioxide and store carbon from the atmosphere, keeping global temperatures stable.
B
Plants release carbon dioxide into the atmosphere through respiration, causing temperatures to decrease.
C
Plants that are consumed remove carbon dioxide from the atmosphere, keeping global temperatures stable.
D
Plants decompose and release carbon dioxide into the atmosphere, causing global temperatures to increase.
The correct statement is:
A. Plants capture carbon dioxide and store carbon from the atmosphere, keeping global temperatures stable.
Plants play a vital role in regulating global temperatures through the process of photosynthesis, which involves capturing carbon dioxide from the atmosphere and converting it into organic compounds. Through this process, plants store carbon in their leaves, stems, and roots, helping to reduce the concentration of carbon dioxide in the atmosphere. Additionally, plants release oxygen into the atmosphere, which is essential for the survival of many living organisms, including humans. While the decomposition of plants can release carbon dioxide into the atmosphere, the overall impact of plants on global temperatures is largely beneficial due to their ability to capture and store carbon.
Hope that helps! Good luck! <3

Mass movement are dangers to people and communities. Outline different kind of mass movement and impacts on people and the environment. Suggest measures that can be used to minimise or prevent mass movements. [for 100 marks]
Mass movements are very dangerous to people and communities, as they can result in loss of lives, damage to infrastructures, and significant long term changes to the landscape.
To outline some of the different kinds of mass movement, we have;
Landslides: It refers to the sudden movement of masses of soil or rock, down the slope, being triggered by several factors including heavy rain, earth quake, etc. They can prove to cause heavy damage to road, building, infrastructures, injuries or loss of life.Earthflow: It refers to the slow-moving, mass movement of soil and rock. They can get triggered by heavy rain, soil saturation, or human activities. Similar to landslide, they can cause similar damages.Creep: It is a slow, gradual movement of soil or rock downhill. Triggered by freeze-thaw cycle, soil expansion, and contraction, etc., they can cause severe damage to infrastructures over-time.Some of the measures, that can be used to minimize or prevent mass movement include;
Land-use planning can be used to prevent the development of mass movement in prone areas.Use of some early warning system can warn people about possible risks, and give some time for people to evacuate safely.Vegetation management should be done to achieve stability of slopes and lands.Thus, by these preventive measure, the possible risks of mass movements can be minimized.

Look at the description of the Sherburne. How was the distance to/ from the shore of the sea changing in the area as the Sherburne was being deposited?
Why are there no fossil ferns or primitive pine trees
Answer from your tutor:
The Sherburne formation is starting to become sandier the closer you get to the top because the shore is starting to transition to sandstone.
How did the distance to/from the shore change as Sherburne was deposited?The Sherburne formation refers to sequence of sedimentary rocks that was deposited in the Late Cretaceous period in what is now Montana and Wyoming which is thought to have been deposited in a shallow marine environment with the shoreline fluctuating over time.
As the Sherburne was being deposited, the distance to/from the shore of the sea was changing in the area. At the bottom of the formation, the sediment is composed of finer-grained rocks such as shale and mudstone which indicate a more offshore environment.
But as you move up the formation, the sediment becomes coarser with the sandstone and conglomerate becoming more prevalent which suggests that the shoreline was moving closer and the area was becoming shallower.

relate exports of raw material from farming and fishery to global economy
Answer:
The exports of raw materials from farming and fishery play a significant role in the global economy. These exports are important for both developing and developed countries as they generate revenue and create employment opportunities.
In many developing countries, agriculture and fishing are the primary sources of livelihood for a large portion of the population. These countries rely heavily on exporting raw materials such as coffee, cocoa, cotton, rubber, palm oil, and seafood to earn foreign exchange and support their economy. For example, countries in Africa, Asia, and Latin America rely heavily on agricultural exports to generate revenue and create employment opportunities.
On the other hand, developed countries import these raw materials from developing countries to produce value-added products, which they then export to other countries. For example, the United States imports a significant amount of coffee, cocoa, and seafood from developing countries and then processes them to produce value-added products such as chocolate, canned tuna, and coffee beans.
Therefore, the exports of raw materials from farming and fishery are an essential part of the global economy, providing income and employment opportunities to millions of people around the world. These exports not only benefit developing countries but also contribute to the growth of developed economies by providing the necessary raw materials to produce value-added products that can be exported to other countries.

. Please calculate the confidence interval based on the conditions below
With 90% confidence, we can say that the true population mean is between 11.448 miles and 12.552 miles.
How to explain the confidence intervalConfidence interval = sample mean ± margin of error
The margin of error is determined by the sample size, the standard deviation, and the level of confidence.
Standard error = population standard deviation / √sample size
Standard error = 3 / √80 ≈ 0.3354
Confidence interval = sample mean ± margin of error
Confidence interval = 12 ± 0.552
Confidence interval = (11.448, 12.552)

what is the impact of coriolis force and latent heat on the development of tropical cyclones
Latent heat and the Coriolis force have a profound impact on how tropical cyclones develop. The earth's rotation results in the Coriolis force, which shifts wind patterns in the northern and southern hemispheres respectively to the right and to the left.
When it comes to tropical cyclones, this force aids in the cyclone's rotation, causing it to spin either clockwise or anticlockwise depending on where it is located.
The energy released when water vapour condenses into liquid droplets is known as latent heat, on the other hand. In this process, warm, moist air rises to the surface and cools, forming clouds and precipitation.
The energy that drives tropical cyclones, which gives them the energy they need to intensify and evolve, is largely derived from the latent heat generated during this process.
