Chapter 12.2, Problem 40E

To determine

To find: the biomass of a tropical tree 30 cm in diameter.

Answer to Problem 40E

508.213 kg

Explanation of Solution

Given:

  

  $\ln y=-2.00+2.42\ln x$

Calculation:

Putting the value of x

  $\begin{array}{c}\ln y=-2.00+2.42\ln x\\ =-2.00+2.42\ln 30\\ =6.23090\end{array}$

Taking the exponential

  $\begin{array}{c}y={10}^{\log y}\\ ={10}^{6.23090}\\ =508.213\end{array}$

Therefore 508.213 kg is the biomass of a tropical tree 30 cm in diameter.
