Question 1 of 10

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

Ellipse

Hyperbola

Circle

Parabola

3. In trigonometry, "sin x" is equal to which of the following? Hint

1/cos x

1/sec x

1/csc x

1/cot x

Question 4 of 10

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? Hint

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.) Hint

SSS

SSA

Question 8 of 10

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? Hint

Focus and Directrix

Focus and Latus Rectum

Directrix and Focus

Directrix and Latus Rectum

Quiz Answer Key and Fun Facts

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

Answer: Hyperbola

In a circle, the x and y coefficients must be equal and positive. In an ellipse, they have to be positive. In a parabola, only one of the terms would be squared.

2. 2x + 3y = 19 and 6x - 3y = 21. Find x and y.

Answer: (5,3)

Add the two equations together, and you get "8x = 40". Divide both sides by 8, and x = 5. Plug x back in to one of the equations and y will equal 3.

3. In trigonometry, "sin x" is equal to which of the following?

Answer: 1/csc x

Cos x equals 1/sec x, and tan x equals 1/cot 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?

Answer: 23

You would not count twice those four members that are in both sets.

Answer: SSA

Side-Side-Side, Angle-Side-Angle, and Side-Angle-Side are all triangle congruency theorems.

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

Answer: 111

111 is divisible by 3 and 37.

7. 5! equals what?

Answer: 120

The "!" means factorial. The natural number preceding that is multiplied by every natural number below it down to 1. 5*4*3*2*1 is 120.

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?

Answer: Focus and Directrix

The vertex of the parabola is one-half the way in between the focus and the directrix.

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

Answer: 100

3(8-3) is 15, and then 5(5+15) equals 100.

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

Answer: 4

An equation always has the same amount of roots as the highest power of the variable, however sometimes these solutions can be the same. Ex: (x - 1)(x - 1) = 0. x = 1 for each of these factors.
