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. Mathematically, it is expressed as a^2 + b^2 = c^2, where a and b are the lengths of the other two sides, and c is the length of the hypotenuse.

How do you find the slope of a line?

To find the slope of a line, you need the coordinates of two points on the line. Then, you can use the formula: slope (m) = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points. Substituting the values into this formula will give you the slope of the line.

What is the equation of a linear function?

The equation of a linear function is typically represented in the form of y = mx + b, where y represents the output variable, x is the input variable, m is the slope of the line, and b is the y-intercept of the line.

How do you simplify expressions with exponents?

To simplify expressions with exponents, you can apply the rules of exponents. When multiplying terms with the same base, you add the exponents. When dividing terms with the same base, you subtract the exponents. When raising a term with an exponent to another exponent, you multiply the exponents. Additionally, any base raised to an exponent of 0 is equal to 1. By applying these rules, you can simplify expressions with exponents efficiently.

What are the different types of angles?

The different types of angles include acute angles (less than 90 degrees), right angles (exactly 90 degrees), obtuse angles (greater than 90 degrees but less than 180 degrees), straight angles (exactly 180 degrees), and reflex angles (greater than 180 degrees). Additionally, angles are also classified as complementary angles (two angles that add up to 90 degrees), supplementary angles (two angles that add up to 180 degrees), and vertical angles (opposite angles formed by intersecting lines).

How do you find the area of a triangle?

To find the area of a triangle, you can use the formula A = 1/2 * base * height, where A is the area, the base is the length of the triangle's base, and the height is the perpendicular distance from the base to the opposite vertex. Simply plug in the values for the base and height into the formula to calculate the area of the triangle.

How do you solve a system of equations using substitution?

To solve a system of equations using substitution, you start by solving one of the equations for one variable in terms of the other. Then, you substitute that expression into the other equation, replacing the variable with the expression you found. This will result in an equation with only one variable, which you can then solve to find the value of that variable. Once you have the value of one variable, you can substitute it back into one of the original equations to find the value of the other variable.

What is the formula for finding the volume of a cylinder?

The formula for finding the volume of a cylinder is V = ?r^2h, where V is the volume, ? is a constant (approximately 3.14159), r is the radius of the base of the cylinder, and h is the height of the cylinder.

How do you add and subtract fractions with unlike denominators?

To add or subtract fractions with unlike denominators, you first need to find a common denominator. To do this, you can either find the least common multiple of the denominators or simply multiply the two denominators together. Once you have a common denominator, you can then adjust the numerators accordingly to make the fractions equivalent. After that, you can add or subtract the numerators and keep the common denominator to simplify the final fraction, if necessary.

How do you solve a quadratic equation using the quadratic formula?

To solve a quadratic equation using the quadratic formula, first ensure the equation is in the form ax^2 + bx + c = 0. Then, you can use the quadratic formula x = [-b ± ?(b^2 - 4ac)] / 2a to find the solutions for x. Simply plug in the values of a, b, and c from the equation into the formula, and calculate the two possible values for x by considering both the positive and negative square root.
