Select the correct answer. Which expression is equivalent to the given expression?
(4 m2m) 2
2m5n
OA. 8m9n 3
OB. 4m9n 3
OC. 4m-in
OD. 8m-in

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

it is ok do not worry about it my dude. have a good one
