1. The half-life of a radioactive substance is the time it takes for half of the substance to decay. The radioactive iodine isotope I-131, which has a half-life of 8 days, is used to treat hyperthyroidism. Solve 400 - 3.125 to find how many days t it will take for 400 millicuries of I-131 to decay to 3.125 millicuries. A 56 days в 7days C 8 days D 128 days 2. In the year 2000, the population of Mexico was about 100 million, and was growing by approximately 1.53% per year. At this growth rate, the function Ax) = 100(1.0153)* gives the population, in millions, x years after 2000. Using this model and a graph of the function, in what year would the population reach 109 million? Round your answer to the nearest year. 2006 C 2005 D 2007 A в 2008 3. Use a graph to solve 3* - 100.
