Algebra Final

3. An equation, graph, or data that can be modeled by a degree 2 polynomial
6. A curve usually expressed in polar coordinates that resembles a figure eight.
7. A set of ordered pairs
8. A polygon with six sides.
9. A geometric figure in three dimensions excluding interior points, if any
10. 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.
13. A polyhedron with eight faces
14. The top part of a fraction
16. Like a line. A description of any graph or data that can be modeled by a linear polynomial
17. Half a circle. That is, a 180°
18. A line segment between two points on the circle or sphere which passes through the center
20. The product of a given integer and all smaller positive integers.
22. The matrix formed by taking the transpose of the cofactor matrix of a given original matrix
23. Straight up and down

1. The result of dividing two numbers or expressions. For example, the 40 divided by 5 has a quotient of 8
2. The mathematics of working with variables
4. A mathematical sentence built from expressions using one or more of the symbols <, >, ≤, or ≥.
5. The part left over after long division
8. A polygon with seven sides
11. Corresponding in size or amount to something else
12. The distance around the outside of a plane figure. For a polygon, the perimeter is the sum of the lengths of the sides.
15. 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
19. Two distinct coplanar lines that do not intersect
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
