What is the area of Figure ABCD? A trapezoid ABCD is drawn with length of parallel sides AB and CD equal to 13 inches and 17 inches, respectively. The length of one of the non-parallel sides BC is 8 inches. Side BC is perpendicular to DC. A perpendicular line drawn from A to side CD meets CD at E.

answer: slight chance that it will happen

step-by-step explanation:

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
