  1. 4. equal parts of a whole or a collection. When we divide a whole into equal parts, each part is a fraction of the whole.
  2. 8. the amount between each number in a geometric sequence. ratio between two consecutive numbers in the sequence. (3,9,27,81) =3
  3. 10. a way of expressing numbers that are too large or too small to be conveniently written in decimal form. Ex,45,000 –> 4.5x10^4, 7.6x10^-4 –>0.00076
  4. 12. sequence of non-zero numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio. An=A1 x r^n-1
  5. 14. When two lines intersect, and form four angles. can also be defined as two adjacent angles that add up to 180°
  6. 17. the equation of a straight line in the form y=mx+b where m is the slope of the line and b is its y-intercept.
  7. 18. the product of multiplying a number by itself, usually represented with a base number and an exponent. 5^3
  8. 19. equation between two variables that gives a straight line when plotted on a graph. Involves a constant and a first-order linear term, where m is the slope and b is the y-intercept, y=mx+b
  9. 20. form of writing a given mathematical concept like an equation, number, or an expression in a form that follows certain rules. Ax+By=C

  1. 1. a way of expressing a number as a product of its prime factors. A prime number is a number that has exactly two factors, 1 and the number itself. Ex, 30 = 5×6, but 6 is not a prime number.
  2. 2. used to find the equation of the straight line which is inclined at a given angle to the x-axis and passes through a given point. y — y1 = m(x — x1)
  3. 3. Lines that go right next to each other and never intersect no matter how long they go. Ex, the opposite sides of a rectangle.
  4. 5. middle point of a line segment. it is the centroid both of the segment and of the endpoints. (X1+X2 /2 , Y1+Y2 /2)
  5. 6. a measure of its steepness. Rise over run. dividing the change in the y-value between two points over the change in the x-value.
  6. 7. quantitative relation between two amounts showing the number of times one value contains or is contained within the other. an ordered pair of numbers a and b, written a:b where b does not equal 0
  7. 9. The numbers that include natural numbers and zero. Not a fraction or decimal. EX, 5,20,10,45
  8. 11. exponents that are fractions, where the numerator is a power and the denominator is a root. The base must be a positive integer.
  9. 13. formed when two parallel lines are intersected by the transversal. angle which occupy the same position at each intersection where a straight line crosses two others
  10. 15. a small number written above and to the right of the base number, tells how many times the base number is being multiplied. it indicates that the base is raised to a certain power. a^5
  11. 16. a numerical measurement of how far apart objects or points are. (x2-x1)^2 + (y2-y1)^2 squared.
