solve question 9 and 10

Question 9 (1 point) The number of frogs in a pond has been decreasing, as indicated in the table below. Year 2005 2006 2007 2008 2009 2010 Number of 200 183 168 153 139 128 Frogs The number of frogs can be modelled by the equation M() = 200(0.abc), where t is the number of years since 2005. In the equation above, the values of a, b, and care, respectively, A/ , and Question 10 (1 point) Saved The population of a specific bacteria growing in a Petri dish is modelled by the function P() = 5000(2)3 where P(t) represents the number of bacteria and t represents the time, in days, after the initial time. How long does it take for the population to double? 1 day 2 days 3 days 9 days
