Question

The population of bacteria in a Petri Dish is growing at a rate of 0.8t^3 + 3.5 thousand per hour. Find the total increase in bacteria during the first 2 hours.

Answer 1

`p=9900\\` bacterias in the initial two hours

Explanation:

the growing rate is given by the ecuation

`p(t)=0.8(t)^(3) +3.5` thousand per hour

for t=2 we have

`p(2)=0.8(2)^(3) +3.5 = 9.9` thousand

`p=9900\\` bacterias

In two hours we have 9900 bacterias
