Element X is a radioactive isotope such that every 6 years, its mass decreases by a half. Given that the initial mass of a sample of Element X is 46 grams, write a function to model the mass of the element.

The magnitude, m, of an earthquake is defined to be m=log l/s, where i is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and s is the intensity of a “standard” earthquake, which is barely detectable. what is the magnitude of an earthquake that is 1,000 times more intense than a standard earthquake? use a calculator. round your answer to the nearest tenth.
