You work on a concrete crew starting a construction project. Once the pouring begins, it must continue non-stop until it is completed. Your crew will work an 8-hour shift along with two
other crews. The total project requires 175,000 yards of concrete. Your supervisor estimates
that each crew will pour around 1200 yards per hour. How many consecutive days should you
plan to work on this project?

step-by-step explanation:

125 yards

step-by-step explanation:

i take 75 plus 50.

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
