The total number of electric cars that are sold each year has been growing exponentially. In the initial year of major production (year zero), 50,000 electric cars were sold world wide. Four years later, the number of cars sold in a year had increased to 500,000. Find the exponential growth constant k and write down an exponential function A(t) that models the number of electric cars sold in year t of major production. According to this model, how many cars will be sold in year ten? How many years (after the initial year of major production) will pass before the number of electric cars sold in a year reaches 100,000,000?

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.
