Three boxes are shipped on a truck. each box has a base of 16 square feet. two of the boxes have a height of 3 feet and one box has a hieght of 5 feet. what is the total volume, in cubic feet, of the three boxes ?

step-by-step explanation:

y=mx+b

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:

a=9
