Connect physical, verbal and symbolic representations of irrational numbers; e.g., construct the square root of 2 as a hypotenuse or on a number line.

Explain the meaning of the nth root.

Use factorial notation and computations to represent and solve problem situations involving arrangements.

Approximate the nth root of a given number greater than zero between consecutive integers when n is an integer; e.g., the 4th root of 50 is between 2 and 3.

Explain how a small error in measurement may lead to a large error in calculated results.

Calculate relative error.

Explain the difference between absolute error and relative error in measurement.

Give examples of how the same absolute error can be problematic in one situation but not in another; e.g., compare "accurate to the nearest foot" when measuring the height of a person versus when measuring the height of a mountain.

Determine the measures of central and inscribed angles and their associated major and minor arcs.
