These problems really aren't hard just set them equal to each other and see if what they are saying is true. Are they equal? Do they both equal 0?
Answer:
4.8x + 0.5
Step-by-step explanation:
Answer:
x = 3
Step-by-step explanation:
A vertical line has the form x = constant. The graph shows the constant you want is 3.
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
