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
