Prove this:cot 75° + cot 15°=4
Answer:
[tex]tan75 {}^{0} = 2 + \sqrt{3} [/tex]
[tex]tan \: 15 {}^{0} = 2 - \sqrt{3} [/tex]
=> cot 75⁰ + cot 15⁰
= cot(90⁰ - 15⁰) + cot(90⁰ - 75⁰)
= tan 15⁰ + tan 75⁰
=
[tex]2 + \sqrt{3} + 2 - \sqrt{3} = 4[/tex]

discuss how far sociologists would agree that students social class is the main factor affecting their educational achievment (12 marks so long answer please, also no frauding bc thats just annoying)
Answer:
Sociologists would probably agree to a large degree with that statement.
Explanation:
The reason is that social class is one of the most important categories of analysis in the academic discipline of sociology. This is because the three authors that are considered to be founders of the discipline: Karl Marx, Émile Durkheim, and Max Webber, all developed social analysis in which social class was transversal and explanatory of many social phenomenons.
Ever since, other sociologists have taken ideas from these three authors, developed them in new forms, and adapted them to more recent historical periods. However, the theme of social class continues to be present in all of them, as one of the most important, if not the most important, variable explaning the social structure of countries, nations, and peoples.

How did Roman emperors use and benefit from the Colosseum?
The Colosseum stands today as a symbol of the power, genius, and brutality of the Roman Empire. It is commonly known as the Flavian Amphitheatre, named after the dynasty of emperors that presided over its construction. Vespasian, who ruled from 69-79 CE, began construction of the Colosseum. Titus, his older son, dedicated the Colosseum and presided over the opening ceremonies in 80 CE. Vespasian’s younger son, Domitian, completed construction of the monument in 81 CE. The funding for building the Colosseum came from the spoils of the Judaic wars that the Flavians fought in Palestine.
Because of earthquake and fire damage, the Colosseum underwent repair until the 6th century. However, after the 6th century, the Colosseum sat in disrepair, was neglected, and used as a quarry for hundreds of years. Some of the outer arcades and most of the inner skeleton of the Colosseum remain intact today.

Read this passage about Amelia Earhart.
Amelia Earhart was born July 24, 1897, in Kansas. She was an adventurous and fun-loving child. That adventurous spirit remained as she grew older. One day in 1920, after going on a plane ride, she was determined to fly planes. She worked at any job she could find to save up for flying lessons, which cost $1,000. At one point, she worked as a nurse’s aid and a social worker. Six months after receiving flying lessons, Amelia bought her own plane, and she flew as high as 14,000 feet, which set a world record for female pilots. A short time afterward, Amelia became the sixteenth female to earn a pilot’s license. In 1928, an opportunity arose for Amelia to participate in a transatlantic flight across the Atlantic Ocean as a copilot. This experience later came in handy when she became the first woman to fly solo across the Atlantic in 1938. She received many honors for this achievement, such as the Distinguished Flying Cross from Congress.
As Amelia approached her fortieth birthday, she was planning her biggest trip yet: She wanted to be the first woman to fly around the world. Of course, she needed a lot of help to make this happen. She made a first attempt that failed and damaged her plane. But Earhart was not one to give up, so she made another attempt at the ground-breaking mission. She did make some progress by flying 7,000 miles to New Guinea but did not make it to her next stop, Howland Island. Sadly, Earhart’s plane disappeared, and, despite search and rescue attempts, she was never found. To this day, Earhart is known and celebrated for her bravery, persistence, and commitment to aviation.
Based on this passage, Earhart best fits in the yearbook category
