Answer:
A
Step-by-step explanation:
The function is 
To find the maximum population, we need to set t towards infinity to get our answer.
So, we replace time with maximum (
). Let's check:

The population of birds approaches 1620 as t goes towards infinity. So we can say the max population of the species is 1620.
Correct answer is A
Answer:
32cm³
Step-by-step explanation:
the volume of a cone is
V
=
π
r
2
h
3
in this case, we can relate
h
and
r
as we know that the slope =
h
r
=
10

=

we can make the volume a formula in a single variable
V
=
π
(

differentiating wrt time, it follows that
