The age of a tree t (in yr) and its corresponding height H t are given in the table. (See Example 8) a. Write a model of the form H t = a + b In t . Round a and b to 2 decimal places. b. Use the model to predict the age of a tree if it is 25 ft high. Round to the nearest year. c. Is it reasonable to assume that this logarithmic trend will continue indefinitely? Why or why not?
