Question

The number of protozoa in a biology laboratory experiment is given by the polynomial function p(t) = 0.0674 +0.31 + 712, where p is the number of protozoa 1 hours.How many protozoa are present after 2 days? Round your answer to the nearest whole number.

Answer 1

`p(t)=0.06t^4+0.3t^3+7t^2`

after 2 days(48 hours):

`\begin{gathered} t=48 \\ p(48)=0.06(48)^4+0.3(48)^3+7(48)^2 \\ p(48)=318504.96+33177.6+16128 \\ p(48)=367811 \end{gathered}`
