A gardener has 40 feet of fencing with which to enclose a garden adjacent to a long existing wall. The gardener will use the wall for one side and the available fencing for the remaining three sides.
If the sides perpendicular to the wall have length x feet, which of the following (A, B, C, or D) represents the area A of the garden? (No explanation required) Choice:
A. A(x) = –2x^2 + 20x
B. A(x) = –2x^2 + 40x
C. A(x) = 2x^2 – 40x
D. A(x) = x^2 – 40x
I say it's B
and based on that
The parabola opens down? agree or not?
Vertex = (10,200)??
The maximum area is 200 sqft?
When the sides perpendicular to the wall have length x = 10ft.
and the side parallel to the wall has length 20ft.
Is this all correct and accurate? Thanks!
