  1. 3. the reverse process of expanding logarithms
  2. 4. formula used for finding the length of a segment
  3. 5. this is typically in a straight line, that best approximates all the individual data points

  5. 9. system two-dimensional plane consisting of the x and y axis. The axes divide the plane into four sections
  6. 10. uses the formula (X1+X2/2, Y1+Y2/2)
  7. 12. the point (0,0)
  8. 14. complete set of possible values of the independent variables
  9. 16. what the four regions on a graph are called
  10. 23. when no x's or y's repeat
  11. 24. to find this you have to multiply the number of degrees by PI/180
  12. 26. angle angle rotated in counter-clockwise
  13. 27. function b is a positive real number not equal to 1 and x occurs as an exponent
  14. 29. the formula A=1/2*r^2*𝛉
