What is the Pythagorean Theorem?

The Pythagorean Theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. In mathematical terms, it can be written as a^2 + b^2 = c^2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

Describe the process of solving a quadratic equation.

To solve a quadratic equation, start by setting the equation equal to zero. Then, use the quadratic formula (-b ± ?(b² - 4ac)) / 2a or factor the equation if possible. If factoring, find two numbers that multiply to the constant term and add up to the coefficient of the linear term. Once you have found the solutions (roots) for the equation, double-check your answers by substituting them back into the original equation to ensure they are correct.

What is the definition of a function in mathematics?

In mathematics, a function is a relation that uniquely associates each element in a set (the domain) with exactly one element in another set (the codomain). It is a rule or a correspondence that assigns to each input a single output.

Explain the concept of the slope-intercept form of a linear equation.

The slope-intercept form of a linear equation is expressed as y = mx + b, where m represents the slope of the line and b is the y-intercept, which is the point where the line crosses the y-axis. The slope indicates the rate at which the line rises or falls, while the y-intercept represents the value of y when x is equal to zero. This form is useful for graphing lines and determining how they behave, making it a fundamental tool in linear algebra and geometry.

Describe the steps involved in graphing a linear inequality.

To graph a linear inequality, start by solving for y to put the equation in slope-intercept form (y=mx+b), where m is the slope and b is the y-intercept. Then, plot the y-intercept on the y-axis and use the slope to find a second point. Next, draw a dashed line through these two points if the inequality is < or >, or a solid line if the inequality is ? or ?. Finally, determine which side of the line to shade by choosing a test point not on the line and checking if it satisfies the inequality. Shade the side that includes solutions to the inequality and label the shaded region if necessary.

What is the difference between permutations and combinations?

The main difference between permutations and combinations lies in the way elements are selected and arranged. Permutations involve selecting and arranging all elements from a set, whereas combinations involve selecting only a subset of elements from a set without considering the order. In other words, permutations focus on the arrangement of elements, while combinations focus solely on the selection of elements regardless of their order.

Explain the concept of exponential growth and decay.

Exponential growth refers to a pattern of growth where the rate of growth is proportional to the current size, resulting in a compound effect over time. On the other hand, exponential decay describes a process where the rate of decrease is proportional to the current size, leading to a rapid decline in value. Both concepts have wide applications in various fields such as finance, population dynamics, and radioactive decay, where understanding how things grow or diminish over time is crucial for analysis and prediction.

Describe the process of factoring a polynomial equation.

Factoring a polynomial equation involves breaking it down into simpler components, or factors. This is done by finding the common factors of the terms in the polynomial and using techniques such as grouping, difference of squares, or trial and error. The goal is to rewrite the polynomial as a product of simpler polynomials. The factored form of the polynomial can then make it easier to solve for the values of the variable that satisfy the equation.

What is the definition of a logarithm?

A logarithm is a mathematical function that gives the exponent to which a fixed number, called the base, must be raised to produce a given number. It is essentially the inverse operation of exponentiation, allowing us to solve equations involving exponential growth or decay. Logarithms are commonly used in various fields such as mathematics, science, engineering, and finance.

Explain the concept of the unit circle in trigonometry.

The unit circle is a circle with a radius of 1 centered at the origin on a coordinate plane. In trigonometry, it is a fundamental tool used to define and understand trigonometric functions. The x-coordinate of a point on the unit circle corresponds to the cosine of the angle formed by the point, while the y-coordinate corresponds to the sine of the angle. This relationship helps to visualize the values of sine and cosine functions for any angle and simplifies trigonometric calculations. The unit circle also aids in understanding the periodic nature of trigonometric functions and their relation to angles in the Cartesian plane.
