In a triangle, a segment is drawn joining the midpoint of two sides. What is true about this segment? Its length is equal to the 3 rd side.
Its length is twice the 3 rd side.
It is parallel to the 3 rd side.
It is ⊥ to the 3 rd side.

step-by-step explanation:

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

lol.

it's ok we all do this sometimes.
