The coordinates of points S and T are 5(-5, 2) and T13./14). What are the coordinates of the point that is, of the way from S to T? OA (1. 11)
B. (-1, 10)
OC (-1,8)
D. (-3,5)

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

the answer is a if my teacher taught me correct
