An official NBA basketball must be inflated so that when it is dropped, it must not bounce back more than 75% of the height from which it was dropped. If a basketball is dropped from a height of 72 inches, what function, r(b), describes the height of the basketball as a function of b, the number of bounces?

The actual width ( w) of a regulation soccer field is 90 meters (m), and the actual length is 120 meters (m). a coach has drawn a scale model of the field on a blackboard. if the longest side of his drawing is 18 cm, how long is the other side of the drawing( w)?

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .

What is the area of a triangle with vertices at (-3 3) (-3,2) and (1,2)?
