Step-by-step explanation:

That's against the Honor Code, if I were you I would study, the bots and community members spectate literally almost every question, they can get deleted as fast as 10 seconds! Study to be on the safe side, I strongly encourage it!

a - base

b - exponent

so,

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
