1. What is the general equation of a circle?

x^2 + y^2 = r^2 · x^2 + y^2 + 2gx + 2fy + c = 0 · a^2x^2 + b^2y^2 = 1 · x^2/a^2 + y^2/b^2 = 1

2. Which of the following is the standard form of the equation of a parabola that opens upwards?

y^2 = 4ax · x^2 = 4ay · x^2 = -4ay · y^2 = -4ax

3. The eccentricity of a circle is:

0 · 1 · 2 · undefined

4. What is the equation of a hyperbola with foci at (±c, 0) and vertices at (±a, 0)?

x^2/a^2 - y^2/b^2 = 1 · y^2/a^2 - x^2/b^2 = 1 · x^2 + y^2 = 1 · x^2 - y^2 = 1

5. If the distance between the foci of a hyperbola is 10 and the distance between the vertices is 6, what is the value of a?

3 · 5 · 4 · 6
