Step-by-step explanation:
sorry but i cannot graph it for you
Answer:
x = 18 cm
y = 9 cm
Step-by-step explanation:
An open-top box will have minimum surface area when it is in the shape of half a cube. The whole cube would have volume 2×2916 = 5832 cm³, so its side length would be ∛5832 cm = 18 cm.
The dimensions of the box are x = 18 cm; y = 9 cm.
__
The surface area is x^2 +4xy, where y = 2916/x^2. That is, the surface area is ...
S = x^2 +11664/x
Setting the derivative to zero, we find ...
dS/dx = 0 = 2x -11664/x^2
x^3 = 5832 . . . . . . . . may look familiar
x = ∛5832 = 18
y = 2916/18^2 = 9
The statement in option D is TRUE.
From the graph, you can see that one eraser cost 50 cent and all the eraser cost the same. Following the graph, you will observe that, when the total cost of the eraser is $3.5 on the vertical axis, the corresponding point on the horizontal axis is 7.
That particular plot on the graph is telling you that when seven erasers are bought, the total cost is $3.5.
