15 Points Per Correct Answer - No time limit  

1. The equation 5y^2 - 3x^2 = 25 will yield what type of graph? (Note: ^ is used as "raised to the power of".) Hyperbola Circle Ellipse Parabola

2. 2x + 3y = 19 and 6x - 3y = 21. Find x and y. (2,5) (8,1) (8,9) (5,3)

3. In trigonometry, "sin x" is equal to which of the following? 1/csc x 1/cot x 1/sec x 1/cos x

4. Set R has 17 members. Set S has 10 members. Set R contains 4 of the same members as set S. How many members would be in the union of set R and set S? 35 27 23 31

5. In geometry, which of these is not a triangle congruency theorem? Note: A triangle congruency theorem is something that can be used to prove two triangles congruent. For example, Angle-Angle-Side is a triangle congruency theorem. This means that two angles in two triangles are congruent as well as a side. Angle-Angle-Side would be different from Angle-Side-Angle, however, because the side in the latter is in between the two congruent angles. (S is side and A is angle.) SAS SSS SSA ASA

6. Which of these is not a prime number (a number that is only divisible by one and itself)? 111 71 31 97

7. 5! equals what? Answer: (One Number, do not use words)

8. A parabola is the locus of all points equidistant from a point and a line. What is the term for that point, and what is the term for that line, respectively? Focus and Directrix Focus and Latus Rectum Directrix and Focus Directrix and Latus Rectum

9. If a?b means a(a+b) and a#b means b(a-b), find 5?(8#3). 100 120 110 130

10. How many roots does the equation "x^4 + 6x^3 - 8x^2 + 10x + 88 = 0" have? 1 3 4 2
