Cuba and US relations essays

Cuba and US relations essays In the early 1900s, Cuba was a stomping ground for many of the rich and famous from the United States. Many famous movies stars and wealthy business entrepreneurs spend their vacations there along with a substantial amount of money. Trade and commerce between the United States and Cuba flowed freely and abundantly. Even with the Dictatorship-like regime of Batista, the countries benefited from the economic trade between them. This was all about to come crashing down as revolts against Batista occurred and Fidel Castro came to power within Cuba. It was after Castro took power that the United States changed its way in which it dealt with Cuba dramatically. The United States decided it would place major sanctions against Cuba and would try to cut Castro off of dealing with not only the United States, but any other country the US dealt with as well. It was during this time that the Cold War was in its adolescence stage and the United States was doing everything in its power to make sure that smaller, third world countries did not become communist or even associate themselves with the Soviet Union in any way. One of the reasons sanctions were placed against Cuba was that during the revolution against Batista, research was done into Castros background and it was shown that two of his lieutenants; Ernesto Che Guevara and Fidels brother Raul, were said to be communists. The research also led one to believe that even though Castro might not be a Marxist-Leninist, he was a Soviet sympathizer . After more in-depth research into Castros background, it was shown that he had no ties in any way to the Communist nor did he even have much sympathy for it. These sanctions were put into place against Cuba as Fidel Castro came into power in 1959 and have not seen any real changes up to the present time. The reason the United States implemented these sanctions against Cuba were for a couple of reasons....

Overview of 12th Grade Math Curriculum

Overview of 12th Grade Math Curriculum By the time students graduate high school, they are expected to have a firm understanding of certain core mathematics concepts from their completed course of study in classes like Algebra II, Calculus, and Statistics. From understanding the basic properties of functions and being able to graph ellipses and hyperbolas in given equations to comprehending the concepts of limits, continuity, and differentiation in Calculus assignments, students are expected to fully grasp these core concepts in order to continue their studies in college courses. The following provides you with the basic concepts that should be attained by the end of the school year where mastery of the concepts of the previous grade is already assumed. Algebra II Concepts In terms of studying Algebra, Algebra II is the highest level high school students will be expected to complete and should grasp all core concepts of this field of study by the time they graduate. Although this class is not always available depending on the jurisdiction of the school district, the topics are also included in precalculus and other math classes students would have to take if Algebra II were not offered. Students should understand the properties of functions, the algebra of functions, matrices, and systems of equations as well as be able to identify functions as either linear, quadratic, exponential, logarithmic, polynomial or rational functions. They should also be able to identify and work with radical expressions and exponents as well as the binomial theorem. In-depth graphing should also be understood including the ability to graph ellipses and hyperbolas of given equations as well as  systems of linear equations and inequalities, quadratics functions and equations. This can often include probability and statistics by using standard deviation measures to compare the scatter of sets of real-world data as well as permutations and combinations. Calculus  and Pre-Calculus Concepts For advanced math students who take a more challenging course load throughout their high school educations, understanding Calculus is essential to finishing off their mathematics curriculums. For other students on a slower learning track, Precalculus is also available. In Calculus, students should be able to successfully review polynomial, algebraic, and transcendental functions as well as be able to define functions, graphs, and limits.  Continuity, differentiation, integration, and applications using problem-solving as the context  will also be a required skill for those expecting to graduate with a Calculus credit. Understanding the  derivatives of functions and real-life applications of derivatives will help students to investigate the relationship between the derivative of a function and the key features of its graph as well as understand the rates of change and their applications. Precalculus students, on the other hand, will be required to understand more basic concepts of the field of study including being able to identify the properties of functions, logarithms, sequences and series, vectors polar coordinates, and complex numbers, and conic sections. Finite Math and Statistics Concepts Some curricula also include an introduction to Finite Math, which combines many of the outcomes listed in other courses with topics which include finance, sets, permutations of n objects known as combinatorics, probability, statistics, matrix algebra, and linear equations. Although this course is typically offered in 11th grade, remedial students may only need to understand the concepts of Finite Math if they take the class their senior year. Similarly, Statistics is offered in the 11th and 12th grades but contains a bit more specific data that students should familiarize themselves with before graduating high school, which include statistical analysis and summarizing and interpreting the data in meaningful ways. Other core concepts of Statistics include probability, linear and non-linear regression, hypothesis testing using binomial, normal, Student-t, and Chi-square distributions, and the use of the fundamental counting principle, permutations, and combinations. Additionally, students should be able to interpret and apply normal and binomial probability distributions as well as transformations to statistical data. Understanding and using the  Central Limit Theorem  and normal distribution patterns are also essential to fully comprehend the field of Statistics.
