If a point is on the perpendicular bisector of a segment, then it is: a. equidistant from the midpoint and one endpoint of the segment. b. the midpoint of the segment. c. on the segment. d. equidistant from the endpoints of the segment

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

-60.75

step-by-step explanation:

just add the numbers then put the negative sign on it
