Circles p, q, and r are shown below. the diameter of circle r is 22.what is the length of pr? thr answre

a = 11 : 4

b = 38

c = 1 for every 6

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

answer: you need to organize this better it does not make sense.
