Question

A colony of bacteria starts with 1000 cells and grows exponentially. The number of cells after t hours is given by B(t)=1000⋅2t. How many bacterial cells will be in the colony after 4 hours?

Answer 1

Answer:

Step-by-step explanation:

1000(2t)

1000(8)

8000 if t is equal to 4 hours

Answer 2

Answer:

16000

Step-by-step explanation:

4 hours later corresponds to t=4. Substitute 4 for t and compute. B(4)=1000(2)4=16,000.
