Dial a quadrilateral abcd with the origin as the center of dilation and a scale factor of 2.5 record the side lengths of the corresponding sides in each quadrilateral round your answer to the hundredths place verify that the ratio of each side length of abcd 2 corresponding side lengths of abcd is equal to the dilation factor

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 3rd on is correct
