The graph shows the distance liam traveled from school in miles v) as a function of time in seconds (x). the graph is divided into
four segments labeled p, q, r, and s, respectively.
distance
(m)
time (sec)
which segment shows liam waiting for a cab?

any options?

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
