Ответ:
The insect population after 6 days is of 1639 insects.
Step-by-step explanation:
A population of insects increases at a rate 230 + 8t + 0.9t2 insects per day
This means that![r(t) = 230 + 8t + 0.9t^2](/tpl/images/1043/7095/9c456.png)
The population of insects after x days is given by:
So
In which K is the initital population(which is 50). So
After 6 days:
Rounding to the nearest insect, 1639
The insect population after 6 days is of 1639 insects.
