The half-life of Palladium-100 is 4 days. After 12 days a sample of Palladium-100 has been reduced to a mass of 2 mg. What was the initial mass (in mg) of the sample? What is the mass 4 weeks after the start?

The value appreciated to $175,000 by the year 2007. Use the compound interest formula S = P(1+r)* to answer the following questions. A) What was the annual growth rate between 1988 and 2007? r = Round the growth rate to 4 decimal places. B) What is the correct answer to part A written in percentage form? r = %. C) Assume that the house value continues to grow by the same percentage. What will the value equal in the year 2010 ? value=$ Round to the nearest thousand dollars.
