<PRE><B>Question 386972</B>
 The number of bacteria is growing exponentially. If the number of bacteria rises from 100 to 350 in 6.5hours, how many bacteria will there be after 14 hours? 
-----
Exponential Form: y = ab^x
350 = 100*b^6.5
---
b^6.5 = 3.5
6.5log(b) = log(3.5)
log(b) = [log3.5]/6.5 = 0.0837
---
b = 10^0.0837
b = 1.2126
======
Equation:
f(x) = 100*1.2126^x
--how many bacteria will there be after 14 hours? 
f(14) = 100*1.2126^14
f(14) = 1485.34
Rounding down you get f(14) = 1485
