the organism grew

Question

The organism grew exponentially.  At first it had 1200 cells.  After two days it had 3000.  How many cells will it have after five more days?

Answer 1

3000 = 1200e^2k is the formula for exponential growth in this problem.

 

2k = ln(3000/1200) = ln(2.5) = .916291 => k =.458145

 

then x = 1200e^.458145*7 = 29646.277123
