A simple technique that biologists use to estimate the age of an African elephant is to measure the length of the elephant's footprint and then calculate its age using the equation

$$l=45-25.7 e^{-0.09 a}$$

where $l$ is the length of the footprint (in centimeters) and $a$ is the age (in years).

Use the equation to find the ages of the elephants with the help of footprint.

This negative aspect of human involvement in the ecosystem could best be described as (1) poor land-use management (2) importation of organisms (3) poor agricultural practices (4) exploitation of wildlife

The function $W(t) = 2600(1 - 0.51e^{-0.075t})^3$ models the weight, $W(t)$, in kilograms, of a female African elephant at age $t$ years. ($1$ kilogram $\approx$ $2.2$ pounds) Use a graphing utility to graph the function. Then $\boxed{TRACE}$ along the curve to estimate the age of an adult female elephant weighing $1800$ kilograms.

A simple technique that biologists use to estimate the age of an African elephant is to measure the length of the elephant's footprint and then calculate its age using the equation

$$l=45-25.7 e^{-0.09 a}$$

where $l$ is the length of the footprint (in centimeters) and $a$ is the age (in years).

Solve the equation for $a$, and use this equation to find the ages of the elephants with the help of footprint.
