Question

A bacteria population doubles in size every 5 hours. After 5 hours, the sample contains 2,000 bacteria. Which equation best models y, the population size after x hours?

Answer 1

Answer:

y = 2000* 2^((x-5)/5)

Step-by-step explanation:

Answer 2

The question seems to be incomplete.

Here is the complete question:

A bacteria population doubles in size every 5 hours. After 5 hours, the sample contains 2,000 bacteria. Which equation best models y, the population size after x hours? y = 1000(1.15)x y = 1000(2)x y = 1000(2.5)x y = 1000(3)x

Answer:

At time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

So that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)
