476×11 =__ i need answer with shown work.

the answer would be 5236

476 x 1 would be 476. then 10 x 476 would 4760, add them together and you will get 5236

:)

8

step-by-step explanation:

this is a subtraction problem.

10 - 2 = 8

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
