Which graph represents the following piecewise defined function? Rx)
1-2x, X<-1
-1.-15X<2
|x-1,822

step-by-step explanation:

it will be a cylinder. with a diameter of 8 and 4 single pieces high

it would take 7/10 of an hour too fill the pool.

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
