Answer:
[tex]p=9900\\[/tex] bacterias in the initial two hours
Step-by-step explanation:
the growing rate is given by the ecuation
[tex]p(t)=0.8(t)^{3} +3.5 [/tex] thousand per hour
for t=2 we have
[tex]p(2)=0.8(2)^{3} +3.5 = 9.9[/tex] thousand
[tex]p=9900\\[/tex] bacterias
In two hours we have 9900 bacterias
