What is the product of 1/2 x -1/4 and 5x^2 - 2x + 6? write in standard form.
(a) show your work.
(b) is the product of 1/2 x -1/4 and 5x^2 - 2x + 6 equal to the product of 1/4 x -1/2 and 5x^2 - 2x + 6
explain your answer.

    the product of the first one is (x-2)/(2)

Step-by-step explanation:

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

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
