Description: The length of the side of a square has been measured accurately to within 0.01 foot. This measured length is 4.25 feet. a. Write an absolute value inequality that describes the relationship between the actual length of each side of the square s and its measured length. b. Solve the absolute value inequality you found in part a. for s.

Key Concepts

Solving Absolute Value Inequalities

This involves rewriting the absolute value inequality as a compound inequality, which represents an interval on the number line. The process entails isolating the absolute value expression and then setting up two simultaneous inequalities that reflect the maximum allowable deviation from the target value.

Measurement Uncertainty

This concept refers to the inherent doubt in any measurement process and specifies the limits within which the true value of the measurement lies. It encompasses the idea that even precise instruments have a margin of error, so the measured value is an approximation of the actual quantity within a certain tolerance.

Absolute Value Inequalities

Absolute value inequalities describe how far apart two values can be by using the absolute value to measure distance on the number line. They are especially useful in expressing conditions where the difference between an actual value and a measured or estimated value must remain within a specific bound.
