Study Notes
Pythagorean Theorem
- Formula: ( a^2 + b^2 = c^2 ) describes the relationship between the sides of a right triangle.
Triangle
- A polygon characterized by having three sides.
Scientific Notation
- Convert ( 3.18 \times 10^6 ) into standard form yields:
- Options include 31,800,000, 3,180,000, and 318,000.
Solving Equations
- Understand types of solutions:
- No solution: The equation is inconsistent.
- One solution: A unique solution exists.
- All numbers true: Equations are identical.
Area of a Circle
- Formula: ( A = \pi r^2 ) used to calculate the space within a circle.
Circumference of a Circle
- Formula: ( C = 2\pi r ) gives the distance around a circle.
Triangle Angles
- The sum of all interior angles in a triangle is always ( 180° ).
Slope in Linear Equations
- In the equation ( y = mx + b ), ( m ) represents the slope, indicating the steepness of the line.
Negative Exponents
- Statement: ( 7^{-1} = \frac{1}{7} ), which is true, while the assertion ( 7^{-1} = -1 \times 7 ) is false.
Quadrilateral
- A polygon that has four sides.
Pentagon
- A polygon with five sides.
Hexagon
- A polygon comprising six sides.
Septagon
- A polygon with seven sides.
Octagon
- A polygon that possesses eight sides.
Nonagon
- A polygon characterized by having nine sides.
Steps for Solving Equations
- Follow a systematic approach:
- Address parentheses first.
- Combine like terms on each side.
- Isolate the variable by rearranging the equation.
- Determine the variable values through multiplication or division.
Integer Definition
- Whole numbers that are not fractions, including positive, negative numbers, and zero.
Handling Negative in Equations
- Rule: The inequality must be flipped when the equation results in a negative number.
