This document provides formulas for calculating the areas of basic shapes: squares, rectangles, triangles, and trapezoids. The area of a square is its side length squared. The area of a rectangle is its base multiplied by its height. The area of a triangle uses the same formula for all triangles, which is half the base times the height. The area of a trapezoid can be found by adding the two bases, multiplying by the height, and dividing by two.

Math Investigation: Pythagorean Theorem
The document illustrates the Pythagorean theorem visually by showing how a larger square can be divided into four triangular regions and a smaller square that together make up the area of the largest square. It provides instructions for readers to cut out and arrange the regions themselves to see how the Pythagorean theorem works. It then suggests two investigation starting points: 1) drawing and cutting out a right triangle with leg lengths of 1 and 2 inches to cover the hypotenuse square, and 2) considering if the same is possible if the smaller leg square is subdivided instead.

Lesson proper area of triangle
The document discusses how to calculate the area of a triangle by relating it to the area of a rectangle. The area of a triangle is equal to one-half the area of its related rectangle, which is formed by extending one of the triangle's sides to form the rectangle's base and using the triangle's height as the rectangle's height. This method can be applied to any triangle by identifying its base, height, and the corresponding related rectangle.
Triangles
Triangles are three-sided polygons that come in three types based on their side lengths: equilateral triangles have all three sides the same length, isosceles triangles have two sides the same length, and scalene triangles have all three sides of different lengths. The area of any triangle can be calculated using Hero's Formula, which uses the triangle's side lengths and semi-perimeter. While Pascal's Triangle is named after Blaise Pascal, he did not invent the triangle - other mathematicians studied and used triangular patterns before him.
Area of triangle
The area of a triangle is calculated by taking half the product of its base and height. To find the area, measure the base and height of the triangle and plug those values into the formula: Area = 1/2 x base x height. This formula gives the area by treating the triangle as half of a rectangle with the same base and height.

It then provides two main methods for solving rational equations - cross multiplying and finding the least common denominator. Several steps are outlined for using the least common denominator method, including finding the common denominator, clearing denominators by multiplying both sides by the LCM, solving the resulting equation, and checking solutions. Examples of using both methods to solve rational equations are shown. Additional resources for learning more about solving rational equations are also provided.
Solving quadratics by graphing
This document discusses how to solve quadratic equations by graphing. It explains that a quadratic equation is of the form y = ax^2 + bx + c, with a being the quadratic term, b the linear term, and c the constant. The number of real solutions is at most two: one solution, two solutions, or no solutions. Solutions are found by setting the equation equal to 0 and finding the x-intercepts of the graph. The graph of a quadratic is a parabola with the roots as the x-intercepts and the vertex as the maximum or minimum point. Quadratic equations can be graphed by making a table of x and y values to plot the parabola.

Sine is the ratio of the opposite side to the hypotenuse. Cosine is the ratio of the adjacent side to the hypotenuse. Tangent is the ratio of the opposite side to the adjacent side. Several examples are provided to demonstrate calculating trigonometric ratios given a right triangle and to find angles or sides using inverse trigonometric functions.
U4 l4 quadratic formula powerpoint
This document provides instruction on solving quadratic equations using the quadratic formula. It explains that the quadratic formula can be used to solve any quadratic equation, even those that cannot be factored. It defines the discriminant (b^2 - 4ac) as an important part of the formula, as the sign of the discriminant determines the number and type of roots. A negative discriminant means there are two complex roots, zero means there is one real root, and a positive discriminant means there are two real roots that can be rational or irrational depending on whether the discriminant is a perfect or non-perfect square. An example problem demonstrates finding the discriminant, describing the roots, and solving a quadratic equation using the formula. Practice

This document explains how to graph linear functions in slope-intercept form by plotting the y-intercept and using the slope. It outlines three steps: 1) Plot the y-intercept point on the y-axis. 2) Use the slope to rise up and run over to plot the next point. 3) Connect the dots with a line to graph the function. It also provides extra examples to demonstrate the process.
Solving inequalities one step
Solving inequalities is similar to solving equations, except the inequality sign changes if multiplying or dividing by a negative number. There are multiple numbers that can satisfy an inequality rather than a single solution. Notation for inequalities includes > for greater than, >= for greater than or equal to, < for less than, and <= for less than or equal to. Examples show solving basic linear inequalities involving addition, subtraction, multiplication, and division.

The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.
