Answer:
The other leg is 16.6 cm (approximately)
Explanation:
We have a right triangle, with the hypotenuse = 18, one side = 7, and the other side = x.
Since this is a right triangle, we will use the Pythagorean Theorem to find the value for x.
So, let a = 7 for one side, and let c = 18 for the hypotenuse. And, let c = x for the other side.
The Pythagorean Theorem is:
c^2 = a^2 + b^2.
So, 18^2 = 7^2 + x^2
324 = 49 +x^2
And, x^2 = 324 - 49 = 275
So, x = sqrt(275) = 16.58 cm (approximately).
Conclusion: The other leg is 16.6 cm (approximately).
Identify and describe a landform that results from water wearing down Earth’s surface.
When water erodes river rocks, they wear away over time. This widens, deepens, and lengthens the bed and banks. During floods, the river's steep sides erode quickly, forming a V-shaped valley.
What is a landform :Over time, the stony walls of a river are eroded and worn away as water flows through the cracks that are created in them by the flow of water.
This results in the bed and banks being more expansive, deeper, and longer respectively.
In addition to this, whenever the river undergoes floods, the erosion that occurs on its steep slopes becomes so quick that it creates a deep valley in the shape of a V.

jack hall (dennis quaid) is a climatologist studying the effects of global warming. why is he taking ice core samples from antarctica? what does this have to do with global warming?
Since Jack hall is studying the effects of global warming. the effect that ice core samples tell about global warming is that Ice cores offer immediate information on past changes in greenhouse gas concentrations as well as direct proof that the climate can shift suddenly in certain situations.
What do ice core samples in Antarctica reveal about global warming?As tree rings are to trees, so are ice cores to ice sheets. Ice cores reveal information about ice sheets in a same way that tree rings do for trees. Jack was collecting ice core samples from Antarctica so that scientists could examine the chemistry and make-up of earlier climates.
To investigate the glacial and interglacial periods, ice cores have been employed. Debris and chemicals are naturally preserved by the ice and snow.
Therefore, Note that Climate scientists examine greenhouse gas concentrations in ice core layers to reconstruct historical climates. Scientists can compute how current carbon dioxide and methane concentrations compare to historical ones.

which factor plays a vital role in the distribution of population. why?
Answer:
fertility playes vital role in distribution of population
Geographical or Physical factor plays a vital role in the distribution of population.
Population distribution refers to the spatial pattern caused by population dispersion, agglomeration creation, linear spread, etc.
High population densities are typically found in lowland plains, flat river basins and deltas, and volcanic regions with good soil. Low population densities are typically seen in mountainous regions with steep slopes and poor soil. Compared to areas that experience more extreme weather and temperatures, temperate zones attract more people. People tend to be more concentrated in areas with a moderate climate that has evenly distributed rainfall or a monsoon-like climate than in areas that are highly dry, severely cold, or extremely wet.The availability of water is vital for human survival and development, therefore regions with enough water (but not too much) tend to have denser populations than those that are dry or frequently experience drought, or those that receive an excessive amount of rainfall or may be vulnerable to flooding.Learn more about Population Density here:

O Archaology
2 pts
The study of information pertaining to a country's, or multiple countries', population is known as Demography. The statistical study of populations, particularly human populations, is called demography. The dimensions and dynamics of populations are examined and measured in demographic analysis, which can be used to entire societies or specific groups based on factors like education, nationality, religion, and ethnicity.
What are the main components of demography?
Demography includes theories and methods for examining human populations. Using age and sex-based classifications, demographic approaches measure the rates of birth, mortality, and both domestic and international migration. Demographic models, which are mathematically defined and used numerically to quantify or project population change, study various regimes of population change for historical and future population structures.
Theories to explain how and why demographic regimes evolve have been put forth to account for historical changes in demographic components. The first demographic transition, which describes a process in which population mortality, fertility, and growth rates reduce sharply, has occurred in the last century.

What kinds of emotional or physical issues might the colonists have difficult to deal with? Why or why not?
Emotional or physical problems that might be difficult for settlers to deal with include depression, fractures, and injuries to vital organs.
What are colonists?The colonists is a term to refer to the group of people who traveled from Europe to America and other regions of the world with the aim of colonizing this territory for the central European empire. The settlers generally had to appropriate land and contribute to the government of the new territories to impose the order of the central government.
What diseases were difficult for the colonists to treat?Traveling to other regions of the world, colonists spent hundreds of days away from home without their families. Due to the above, it was possible that they had episodes of depression that affected them emotionally because they felt bad because of the distance from their relatives.
On the other hand, when they arrived in inhospitable places, they used to be greeted with climatic conditions different from what they were used to and on many occasions the natives were hostile towards them. Due to the above, the settlers had to deal with unknown diseases and injuries caused by the natives that in many cases were difficult to treat because they did not have access to the necessary medical elements to treat wounds and diseases of this type.

What impact does emigration have on a region with a high population density?
Emigration reduces the carrying capacity of the region.
Emigration does not impact regions with high population densities.
Emigration results in loss of jobs in the region.
Emigration increases the availability of resources within the region.
Emigration results in greater immigration to the region.
Answer:
The correct answer is B. Emigration does not impact regions with high population densities.
Explanation:
Regions with high population densities are not affected by the emigration of their inhabitants to new destinations.
Although they suffer a fall in their population, the highly populated regions have all their available resources occupied in production, so there is generally a little percentage of population that is unemployed. This causes many of the migrants to be unemployed seeking job opportunities; and if the emigrant is a person who leaves his position, another person who is looking for a job can replace him.
In addition, except for exceptional cases of mass migration, migration rates do not affect these areas as if they do in less populated areas such as rural areas.
