How to divide u by v, subtract t from the result, then add w to what you have. I don't understand

Step-by-step explanation:

( u ÷ v - t ) + w

divide u and v, after u get the ans subtract it with T.

then add w.

center= (-2,0)

radius= sqrt2/2

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
