O A. Yes, the lines L, and L, are perpendicular because the product of their
slopes equals - 1
O B. No, the lines L, and Ly are not perpendicular because the product of
their slopes equals - 1
OC. No, the lines L, and I are not perpendicular because the product of
their slopes does not equal - 1
OD. Yes, the lines L, and Ly are perpendicular because the product of their
slopes does not equal - 1.
ET
Answer:
OD
Explanation:
YES, THE LINES L AND LY ARE PERPENDICULAR SLOPES DOES NOT EQUAL
Yes, line L1 and L2 are parallel because they have the same slope. Correct option is B.
To calculate the slope of the line passing through the points (0, 2) and (8, 4), you can use the formula for the slope of a line:
Slope (m) = (y2 - y1) / (x2 - x1)
Given the points:
Point 1: (x1, y1) = (0, 2)
Point 2: (x2, y2) = (8, 4)
Substitute the coordinates into the formula:
Slope (m) = (4 - 2) / (8 - 0)
Slope (m) = 2 / 8
Slope (m) = 0.25
The slope of the line passing through the points (0, 2) and (8, 4) is 0.25.
To calculate the slope of the line passing through the points (-8, -6) and (0, -4), you can use the formula for the slope of a line:
Slope (m) = (y2 - y1) / (x2 - x1)
Given the points:
Point 1: (x1, y1) = (-8, -6)
Point 2: (x2, y2) = (0, -4)
Substitute the coordinates into the formula:
Slope (m) = (-4 - (-6)) / (0 - (-8))
Slope (m) = (-4 + 6) / 8
Slope (m) = 2 / 8
Slope (m) = 0.25
The slope of the line passing through the points (-8, -6) and (0, -4) is 0.25.

why is the Rift Valley of Ethiopia is the most geologically unstable area in the country?
[tex] \huge{\underline \mathscr{ \pink{Answer }}} :[/tex]
The Earth’s mantle is made up of Tectonic plates that are forever moving as the Earth cools down. This happens over billions of years, and one of the most notable ones is around the Pacific rim where Earthquakes, (seismic activity) happens quite often
The Rift Valley in Ethiopia lies along the edge of the African Tectonic Plate, and continues down through parts of Somalia and into Kenya.
Just recently a rift opened up in Kenya, which seismologists seem to think is the pre-cursor of a major tectonic plate movement, splitting apart a part of Africa, which could include Ethiopia.
What type of weather conditions can lead to wildfires
Wildfires can occur anywhere but are common in the forested areas of the United States and Canada. They are also susceptible in many places around the world, including much of the vegetated areas of Australia as well as in the Western Cape of South Africa. The climates are sufficiently moist to allow the growth of trees, but feature extended dry, hot periods. Fires are particularly prevalent in the summer and fall, and during droughts when fallen branches, leaves, and other material can dry out and become highly flammable. Wildfires are also common in grasslands and scrublands.

Sixty-five percent of global greenhouse gas emissions are made up of carbon dioxide, while only sixteen percent are made up of methane gas. Which of the following best explains why scientists are increasingly concerned about the effect of methane gas emissions on global climate if they are a relatively small percent of greenhouse gases released?.
The statement that best explains why scientists are increasingly concerned about the effect of methane gas emissions on global climate is that the Methane gas has a higher global warming potential (GWP) than carbon dioxide does, so it can trap more heat in the atmosphere.
What is Global warming?Global warming is also called climatic change because of the existence of heating of Earth's climate system which are primarily due to human activities.
Hence, the scientist are more concern because Methane gas has a higher global warming potential (GWP) than carbon dioxide does, so it can trap more heat in the atmosphere.

Answer:
through providing more education
The natural process is what caused Coriolis force and latent heat to contribute to the development of Ingrid tropical cyclone
Generally, as the Earth rotates toward the east, this rotation causes fluids, such as air and currents to be deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.
This rotation are what causes Cyclones which are usually common in areas of low pressure.

Explain how the risk of tectonic hazards can be reduced (4 marks - include 4 ways)
To reduce vulnerability, organisations such as the United States Geological Survey (USGS), governments and charities need to do the following.
Reduce the impact of hazard
Monitoring tectonic activity using equipment may help predict and identify major events. In addition to this, setting up evacuation zones and hazard mapping are helpful techniques to reduce the impact of a hazard.
Build capacity to cope with the hazard
Educating people about what to do, and having regular earthquake drills, are helpful in building capacity to cope. In addition, having well equipped emergency service teams who are well trained also increases a country’s ability to cope. Buildings can also be designed in a way to better survive earthquakes. From skyscrapers in San Francisco, USA, to new community centres in Kali Jawi, Indonesia, buildings can be made earthquake proof.
Tackle the root cause of the vulnerability
Governments and organisations can help reduce the vulnerability by actively trying to reduce inequality and poverty in countries. Everyone, regardless of wealth, should have the same status and right to protection.
