Use cylindrical coordinates. Evaluate e z dv, where e is enclosed by the paraboloid z = x2 y2 and the plane z = 16.

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

+1 +3 +5 +6

i would guess 26 because this isnt a sequential pattern or its to short to know

25/32 is the simplest form
