4. a laser beam travels along a straight path for a certain distance, and then bounces n
times off tilted mirrors before striking a target. the laser beam travels v2 additional
centimeters each time it bounces off a mirror. when there are 5 bounces, the laser
beam travels 132 cm.
a. let d (n) denote the distance the laser travels in cm as a function of the number
of bounces off a mirror, n. what does d(5) represent? what is the value of d(5)?
