Algebra Final

1. Like a line. A description of any graph or data that can be modeled by a linear polynomial
5. 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
6. A geometric figure in three dimensions excluding interior points, if any
7. Straight up and down
8. The product of a given integer and all smaller positive integers.
10. The top part of a fraction
13. A mathematical sentence built from expressions using one or more of the symbols <, >, ≤, or ≥.
15. Corresponding in size or amount to something else
19. A line segment between two points on the circle or sphere which passes through the center
21. The result of dividing two numbers or expressions. For example, the 40 divided by 5 has a quotient of 8
22. The matrix formed by taking the transpose of the cofactor matrix of a given original matrix
23. A polygon with seven sides
24. 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.

2. The mathematics of working with variables
3. A polygon with six sides.
4. The distance around the outside of a plane figure. For a polygon, the perimeter is the sum of the lengths of the sides.
9. A curve usually expressed in polar coordinates that resembles a figure eight.
11. A polyhedron with eight faces
12. Half a circle. That is, a 180°
14. An equation, graph, or data that can be modeled by a degree 2 polynomial
16. The part left over after long division
17. Two distinct coplanar lines that do not intersect
18. A set of ordered pairs
20. 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
