Top ross Sections and Plane Rotations - 11/3/MC Consider an isosceles trapezoid rotated about an axis of symmetry that passes through the midpoint of the bases.
The minor base of the trapezoid is 5 cm and the major base is 10 cm.
What is the perimeter of the horizontal cross section if the cut is made at the middle of the height of the trapezoid?

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
