Step-by-step explanation:
Answer: Algebra acts as a tool to improve communication because much like learning a new language, you have to take baby steps before you can fully get it. This can improve communication because you're learning something new with the help of others.
The domain is y >=0. Domain is the possible x values
I would estimate about 240
Area=length*width
let the sides perpendicular to the river be x
then the side parallel to the river is 4,700-2x
A(x)=x(4700-2x)
A(x)=4700x-2x^2
This a quadratic function with a=-2 and b=4700
thus
Maximum area occurs where x=-b/2a=-4700(-2*2)=1,175 ft
length=4700-2(1175)=2,350 ft
