answer:
Three points are: (-2,0) , (0,1) , (2,2)
Step-by-step explanation:
Given: -x+2y=2
Put x=0 into -x+2y=2
2y=2
y=1
Point: (0,1)
Put x=-2 into -x+2y=2
2+2y=2
y=0
Point: (-2,0)
Put x=2 into -x+2y=2
-2+2y=2
y=2
Point: (2,2)
Three points are: (-2,0) , (0,1) , (2,2)
Answer:
12
Step-by-step explanation:
Answer:
bottom side (a) = 3.36 ft
lateral side (b) = 4.68 ft
Step-by-step explanation:
We have to maximize the area of the window, subject to a constraint in the perimeter of the window.
If we defined a as the bottom side, and b as the lateral side, we have the area defined as:
The restriction is that the perimeter have to be 12 ft at most:
We can express b in function of a as:
Then, the area become:
To maximize the area, we derive and equal to zero:
Then, b is:
