Why is the dependency ratio important?

At the end of the year 2004 , the total reserve of a mineral was $350,000 \mathrm{~m}^3$. In the year 2005 , about $5000 \mathrm{~m}^3$ of this mineral was used. How long will the reserves last if the annual usage stays constant at $5000 \mathrm{~m}^3$ per year?

In this exercise, use the data table below.

Simplify the ratio. $20:$5

Show that the ratio of the displacements at two successive maxima is given by $\exp \left(\gamma T_d / 2 m\right)$. Observe that this ratio does not depend on which pair of maxima is chosen. The natural logarithm of this ratio is called the logarithmic decrement and is denoted by $\Delta$
