Freedom 7 was the spacecraft that carried the first American into space in 1961. Total flight time was 15 minutes and the spacecraft reached a maximum height of 116 miles. Consider a function, s, that expresses Freedom 7’s height, s(t), in miles, after t minutes. Is s a one-to-one function? Explain your answer.
Body surface area is an important piece of medical information because it is a factor in temperature regulation as well as some drug level determinations. The Mosteller formulat gives one way of estimating body surface area 8 in square meters. The formula uses the weight w in kilograms and the height h in centimeters. The relation is Vhw 60 In this exercise we consider people who are 190 centimeters tall. (a) Write a formula for 8 as a function of w. (b) Make a graph of 8 versus w.
