1. What is the standard form equation of an ellipse centered at the origin with a horizontal major axis?
x²/a² + y²/b² = 1
x²/b² + y²/a² = 1
(x-h)²/a² + (y-k)²/b² = 1
(x-h)²/b² + (y-k)²/a² = 1
2. For an ellipse, the sum of the distances from any point on the ellipse to the two foci is equal to:
2c
2a
2b
a + b
3. The of an ellipse is the longest diameter, passing through both foci and vertices.
4. The distance from the center to each focus is denoted by .
5. Consider the ellipse with the equation (x²/25) + (y²/9) = 1. Identify the lengths of the major and minor axes, the coordinates of the vertices, and the coordinates of the foci.
6. An ellipse is a set of all points in a plane such that the sum of the distances from two fixed points (foci) is constant.
True
False
7. Graph the ellipse given by the equation x²/16 + y²/4 = 1. Label the vertices and foci.
