Question

Forensic scientists use the lengths of certain bones to calculate the height of person.  A bone often used is the tibia (t), the bone from the ankle to the knee. A man’s height (h) is determined from the length of this bone using a function defined by the following formula:
h(t) = 81.69 + 2.39t
 Find the height of a man with a tibia measuring 40 centimeters

Steve · Answer

h(t) gives the height for any value of t. For this problem, wherever you see a t, substitute 40: h(40) = 81.69 + 2.39*40
