Chapter 1.2, Problem 5E

Reminder Round all answers to two decimal places unless otherwise indicated.

Choosing a Bat A chart from Dick’s sporting Goods gives the recommended bat length $B$ in inches for a man weighing between $161$ and $170$ pounds as a function of his height $h$ in inches. The table is partially reproduced on the next page.

$h=\text{Height}$	$B=\text{Bat}\text{length}$
$45-48$	$30$
$49-52$	$31$
$53-56$	$31$
$57-60$	$32$
$61-64$	$32$
$65-68$	$33$
$69-72$	$33$
$73+$	$33$

a. Explain in practical terms the meaning of $B\left(55\right)$ and give its value.

b. Use functional notation to express the recommended bat length for a man weighing between $161$ and $170$ pounds if his height is $63\text{inches}$.
