10)Solve log x-1 = - log(x- 9)

11) Suppose that you are observing the behavior of cell duplication in a lab. In one experiment, you

started with 200 cells: 50 of those cells doubled every 30 minutes, 100 of those cells duplicated

every hour and the other 50 could not duplicate.

a) Write an equation to determine the number(population) of cells after one hour.

b) How many cells exist after 1 hour?

c) How long would it take to get to 1000 cells?
