1st Period

1 integer
1. integer
  • any of the natural numbers, the negatives of these numbers, or zero
2 rational number
2. rational number
  • a number that can be expressed as an integer or the quotient of an integer divided by a nonzero integer
3 scientific notation
3. scientific notation
  • a widely used floating-point system in which numbers are expressed as products consisting of a number between 1 and 10 multiplied by an appropriate power of 10 (as in 1.591 × (10)−20 or 1.591 × 10 − 20)
4 perfect square
4. perfect square
  • an integer (as 9 or 36) whose square root is an integer
5 irrational number
5. irrational number
  • a number that can be expressed as an infinite decimal with no set of consecutive digits repeating itself indefinitely and that cannot be expressed as the quotient of two integers
6 real numbers
6. real numbers
  • a number that has no imaginary part <the set of all real numbers comprises the rationals and the irrationals>
7 density property
7. Density Property
  • The property that states that there always exists another rational number between any two given rational numbers. This means that the set of rational numbers is dense.
8 adjacent angles
8. Adjacent angles
  • having the vertex and one side in common
9 coefficient
9. Coefficient
  • The number part in front of the non-numerical symbol(s) in an algebraic expression, signifying multiplication. For example, the number 4 in the expression 4xy is a coefficient.
10 distance formula
10. Distance Formula
  • The distance between two points (x1, y1) and (x2, y2) in the Cartesian coordinate system can be given by: [(x1 - x2)2 + (y1 - y2)2]1/2
11 domain
11. Domain
  • The set of all possible input values for a function or relation.
12 hypotenuse
12. Hypotenuse
  • The side opposite the right angle in a right triangle.
13 legs of a right triangle
13. Legs of a right Triangle
  • Either of the two sides that form the right angle in a right triangle or one of the two congruent sides in an isosceles triangle.
14 rational number
14. Rational Number
  • A number that can be written as a fraction, or as finite or repeating decimals.
  • The square root of 2 (1.414 213 6...) is not a rational number.
15 range
15. Range
  • The difference between the maximum and minimum values in a set of data.
16 slope
16. Slope
  • Another name for gradient
18 prism
18. Prism
  • A polyhedron with two parallel, congruent polygons being its bases and all the other faces being parallelograms.
  • The line joining the centers of the bases is called the axis of the prism. When the axis is at right angles to the base, the prism is called a right prism. In this case, the lateral faces are rectangles. Otherwise, it is called an oblique prism.
  • A prism is also classified based on the type of its base. It is called a triangular prism when it has triangular bases. Many of the glass prisms used in optical instruments possess this shape. A prism is called a quadrangular prism when it has a quadrilateral base. The cube is a quadrangular prism with square bases and square lateral faces.
19 scatter plot
19. Scatter plot
  • Data that is plotted as points on a graph to show a possible relationship between two sets of data.
