ALGEBRA FINAL

3. The mathematics of working with variables
5. A polyhedron with eight faces
7. A geometric figure in three dimensions excluding interior points, if any
10. A curve usually expressed in polar coordinates that resembles a figure eight.
11. An assertion that can be proved true using the rules of logic. A theorem is proven from axioms, postulates, or other theorems already known to be true
14. Like a line. A description of any graph or data that can be modeled by a linear polynomial
15. A mathematical sentence built from expressions using one or more of the symbols <, >, ≤, or ≥.
16. . A polygon with six sides
18. The distance around the outside of a plane figure. For a polygon, the perimeter is the sum of the lengths of the sides.
19. A set of ordered pairs
20. The study of geometric figures in two dimensions (plane geometry) and three dimensions (solid geometry). It includes the study of points, lines, triangles, quadrilaterals, other polygons, circles, sp
22. The result of dividing two numbers or expressions. For example, the 40 divided by 5 has a quotient of 8
23. Another word for average. Mean almost always refers to arithmetic mean. In certain contexts, however, it could refer to the geometric mean, harmonic mean, or root mean square.

1. The product of a given integer and all smaller positive integers.
2. Two distinct coplanar lines that do not intersect
4. Corresponding in size or amount to something else
6. An equation, graph, or data that can be modeled by a degree 2 polynomial
8. Half a circle. That is, a 180°
9. Straight up and down
12. The part left over after long division
13. The top part of a fraction
16. A polygon with seven sides
17. The matrix formed by taking the transpose of the cofactor matrix of a given original matrix
21. A line segment between two points on the circle or sphere which passes through the center
