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

Answer:

$p=9900$ bacterias in the initial two hours

Step-by-step 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
