This shape is made out of rectangles each 4 units tall; the rectangle at the very bottom is 16 units wide; each next rectangle is half the width of the one below it.
There are so many rectangles that the finished drawing would not fit on the page, so
you can see that the drawing is incomplete. Calculate the area of the entire shape
even the part that is not drawn.

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

the answer is a.
