• The product of two numbers is the result when they are multiplied together.
• Compound Interest Formula?


  A = P (1 + r/n)^(n\*t)
• What is compound interest?


  Interest earned on both the principal amount and any accrued interest over time.
• What is the effect of increasing the compounding frequency?


  The final amount increases, as interest is earned more frequently.
• Rate per annum - The annual rate of interest expressed as a decimal.
• A factorial (n!) is the product of all positive integers less than or equal to n.
• An integer is any whole number, including zero.
• A prime number is a whole number greater than one that has no positive divisors other than one and itself.
• To find factors, we need to divide the given number into pairs of equal parts or use trial and error.
• Two lines are parallel


  They have the same slope but different y-intercepts
• Two lines are perpendicular


  They have different slopes and intersect at a right angle
• m > 0


  The line slopes upward from left to right.
• m = 0


  The line is horizontal.
• m < 0


  The line slopes downward from left to right.
• m = ∞ or 0/0


  The line is vertical.
• Multiples are numbers that can be divided evenly by another number without leaving a remainder.
• how many centimeters in a meter

• What is the formula to calculate the interior angle of a regular polygon?

  Interior Angle = Sum of the interior angles of a polygon / n
• What does "n" represent in the formula for the interior angle of a polygon?

  "n" represents the number of sides of the polygon
• What is the formula to calculate each angle of a regular polygon?

  Each Angle = (n − 2) × 180° / n
• How do you calculate the sum of the interior angles of any polygon?

  The sum of the interior angles can be calculated using the formula 180(n - 2)°
• What is the formula for the sum of the interior angles of a polygon?

  Sum of the interior angles = 180(n - 2)°
• What are the key formulas for calculating angles in polygons?

  • Interior Angle of a Regular Polygon: Interior Angle = Sum of the interior angles of a polygon / n
  • Each Angle of a Regular Polygon: Each Angle = (n − 2) × 180° / n
  • Sum of Interior Angles: Sum = 180(n - 2)°
• What are inverse functions?

  Functions that reverse or "undo" another function
• How do we denote the inverse of a function $f$?


  $f^{-1}$
• How can we find the input from a known output using inverse functions?

  By using a function machine to work backwards
• What is the first step to find an inverse function?

  Rewrite the function using $y$ as the unknown variable and set the function equal to $x$
• After setting the function equal to $x$, what must we do next to find the inverse function?


  Rearrange the function to make $y$ the subject
• What notation is used to write the inverse function after rearranging?

  Inverse function notation
• How can inverse functions be applied in solving equations?

  They can be used to find missing $x$ values on graphs if we know the $y$ value
• What is the process to find an inverse function?

  1. Rewrite the function using $y$ as the unknown variable.
  2. Set the function equal to $x$.
  3. Rearrange the function to make $y$ the subject.
  4. Write the function using inverse function notation.
