Independent Practice (HW)
Home decorating: A remnant of carpet in the shape of a square is advertised as 16 square yards. That will cover an area that measures 4 yards by 4 yards.
Law enforcement: In order to find the speed of a car after a collision, an investigator can measure the length of the skid marks (L) and apply the formula: speed = 2
Computer programming: Square root and absolute value functions are often used in computer programming to ensure a positive number is used for calculations.
