Convert the following measurements. a. 2 cubic yards to cubic feet b. 135 cubic feet to cubic yards c. 6,912 cubic feet to cubic inches d. 279,936 cubic inches to cubic feet

Step-by-step explanation:

a. Remember that:

Then, 2  cubic yards to cubic feet is:

b. 135 cubic feet to cubic yards is:

c. Remember that:

Then, 6,912 cubic feet to cubic inches:

d. 279,936 cubic inches to cubic feet is:

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
