Algebra Final

5. Corresponding in size or amount to something else
8. Two distinct coplanar lines that do not intersect
10. A polyhedron with eight faces
12. The distance around the outside of a plane figure. For a polygon, the perimeter is the sum of the lengths of the sides.
13. An equation, graph, or data that can be modeled by a degree 2 polynomial
18. The part left over after long division
19. A set of ordered pairs
21. 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
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.
24. Straight up and down

1. A polygon with seven sides
2. The product of a given integer and all smaller positive integers.
3. Half a circle. That is, a 180°
4. A mathematical sentence built from expressions using one or more of the symbols <, >, ≤, or ≥.
6. A geometric figure in three dimensions excluding interior points, if any
7. A curve usually expressed in polar coordinates that resembles a figure eight.
9. Like a line. A description of any graph or data that can be modeled by a linear polynomial
11. The top part of a fraction
14. The result of dividing two numbers or expressions. For example, the 40 divided by 5 has a quotient of 8
15. The mathematics of working with variables
16. 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
17. A line segment between two points on the circle or sphere which passes through the center
20. The matrix formed by taking the transpose of the cofactor matrix of a given original matrix
22. A polygon with six sides.
