- A pattern of dots grows exponentially. The table shows the number of dots at each step of the pattern. step number 012 3 number of dots 15 25 125 1. Write an equation to represent the relationship between the step number, n, and the number of dots, y. 2. At one step, there are 9,765,625 dots in the pattern. At what step number will that happen? Explain how you know.arrow_forwardA 18. Lucy is growing bacteria in a petri dish. She starts with 50 bacterial cells and notices after one hour she has 80 cells. After two hours, she has 128 cells. What is the exponential equation that determines how many bacterial cells are in the dish for any given hour? y = 50 - 1.6* y = 1.6 - 50* y = 128 · 50* y = 50 + 1.6xarrow_forwardFind the solution of the exponential equation, as in Example 1.
