Could someone please tell me if this is correct?
A cell divides into two cells every 20 minutes. The initial population of a culture is 60 cells
Find and expression for the number of cells after t hours:
(0,60) (20, 132)
Find the number of cells after 8 hours:
Find the rate of growth after 8 hours:
Isn't that just -2.2% but it can't be negative. ???????????
When will the population reach 20,000 cells?
t=-2.63 This can't be right. It can't be a negative number, right?
Thank you very much
Where did you get 480 from? Can you show me how to set up the formula? If I were to have had the right numbers would that have worked?secondly, your formula was designed for t measured in minutes, you can't plug in 8 for t then, you would need to plug in 480. otherwise, make your formula with respect to hours to begin with
20 minutes = 1/3 hour, so begin by solving for
