A culture is grown with a population of 45 million cells. The cell population is found to double every hour. What will the popul
Alexandra [31]
45 million * 2^{4} = 45million * 16 = 720million

Or you can use 
y=Ae^{kt}
A is equal to 45 million
To find the rate, k, we can plug in:
90million=45million*e^{k*1}&#10;
2=e^{k}
k=ln(2)
y=4.5*10^{7}*e^{t *ln2}
Knowing that t = 4
y = 4.5*10^{7}*e^{ln(2)*4}&#10;
y = 720 million
