a culture started with 6,000 bacteria. After 4 hours, it grew to 6,600 bacteria. Predict how many bacteria will be present after 10 hours. round your answer to the nearest whole number.

Respuesta :

P = 6,600  

A = 6,000  

t = 4  

k = ?  


6600 = 6000e^(4k)  

6600/6000 = e^(4k)  

1.1 = e^(4k)  


Take the natural log of both sides.  


ln 1.1 = 4k ln e (remember that ln e = 1)  

ln 1.1 = 4k  

(ln 1.1) / 4 = k  

k = 0.0238  


Bacteria after 10 hours.  

P = 6000e^(0.0238*10)  

= 6000e^0.238  

= 7612  


Therefore, the bacteria will grow to 7612 after 10 hours.
