Half-life and population doubling
Half-life and population doubling
What you'll learn
- Identify the center, major axis, minor axis, vertices, co-vertices, and foci of an ellipse given its equation in general form, and convert it to standard form with 100% accuracy on a formative assessment.
- Solve problems by writing the equation of an ellipse in standard form given its center, the length of its major and minor axes, and the orientation of the major axis with 80% accuracy on a summative quiz.
- Apply knowledge of completing the square to rewrite the equation of an ellipse from general form to standard form, justifying each step in the process with mathematically sound reasoning in a written explanation.
- Explain the relationship between the values of 'a', 'b', and 'c' in the standard form equation of an ellipse and the geometric properties of the ellipse, including the location of the foci, with clear and concise mathematical language.
