dr silas studies a culture of bacteria under a microscope. the function b1(t)=1200(1.8)t represents the number of bacteria t hours after dr silas begins her study. (a) what does the value 1200 represent in this situation? (b) what does the value 1.8 represent in this situation? (c) the number of bacteria in a second study is modeled by the function b2(t)=1000(1.8)t. what does the value 1000 represent in this situation? what does the difference of 1200 and 1000 mean between the two studies?

Juliana says that she can use the patterns of equivalent ratios in the multiplication table below to write an infinite number of ratios that are equivalent to 6: 10. which statement explains whether juliana is correct? she is correct because she can multiply 6 and 10 by any number to form an equivalent ratio. she is correct because 6: 10 can be written as 1: 2 and there are an infinite number of ratios for 1: 2. she is not correct because the multiplication table does not include multiples of 10. she is not correct because 6: 10 is equivalent to 3: 5 and there are only 9 ratios in the multiplication table that are equivalent to 3: 5.
