Determine the profit function.
Profit function is calculated as thus:

So, we have:



Answer:
volume of fodder=1/3pie R^2h=
l^2=r^2+h^2
l^2=(2.1)^2+(3.6)^2
l^2=4.441+12.96=17.37
l=
=4.17m
minimum area of polythene to cover fodder=pieRl=
the volume of fodder is
and minimum area of polythene to cover fodder in the rainy seasonv47.18m^3
The answer is the first choice.
H=-t^2+95
The y intercept here is 95, and it represented from where the boy threw the ball.
