1. Explain the difference between a “reserve” and a “resource”. What factors influence estimates of reserves and resources for commodities such as minerals or fossil fuels? Resources and reserves are similar in that the both benefit humanity. Resources are materials that can be used to satisfy human needs‚ or used as support. Reserves on the other hand are known deposits with the ability to extract the available material economically; the size of these reserves is not always known or defined

In Mathematics‚ a periodic function is a function that repeats its values in regular intervals or periods. Periodic functions are used throughout science to describe oscillations‚ waves‚ and other phenomena that exhibit periodicity. Periodic functions are those that repeat on a set interval. All trigonometric functions are periodic. They are useful because one can determine the value of the function anywhere in the domain. If a function is periodic‚ then there is some value n for which

Aluminum GuttersOf all the types of gutters to choose from‚ there is a very good reason why aluminum dominates the gutter market. The metal is corrosion-resistant‚ lightweight‚ easy to work with‚ available in wide range of colors‚ and less expensive than the other alternatives. Copper GuttersCopper gutters will not hold up that much better or last longer than aluminum gutters for the added cost. There are certain long term and short term advantages to copper gutters‚ as long as they are installed
