Answer 1

note: when solving for k round to 4 decimal places

Answer 2

\[P=Ae ^{kt}\]

Answer 3

In 4 hours the culture grow up with 2,600-2,000=600 bacteria

We use the 3 simple rule:

4hours........600 bacteria
17hours.........x

x= 17*600/4

x=17*150

x=2,550 bacteria grew in 17 hours

The culture started with 2,000 bacteria so we have to add the ones formed in 17 hours

2,000+2,550= 4,550 bacteria were in total after 17 hours rounded it would be 5,000
