Find the specified term for each geometric sequence.

Melina receives a chain email that she forwards to 7 of her friends. Each of her friends forward it to 7 of their friends. Write an explicit formula for the pattern. How many will receive the email after 6 forwards?

A bacteria divides every 15 minutes to produce two complete bacteria. a) If an initial colony contains a population of bacteria, write an equation that will determine the number of bacteria present after t hours. b) Suppose a Petri dish contains 12 bacteria. How many bacteria will be present after 4 hours?

You are an accountant for a small company. On January 1, 2009 the company purchased $50, 000 worth of computers, printers, scanners, and hardware. Because this equipment is a company asset, you need to determine how much the computer equipment is presently worth. You estimate that the equipment depreciates at a rate of 45% per year. What value should you assign the equipment in the 2014 year-3 nd accounting report?
