The function v(r) = four-thirds pi r cubed can be used to find the volume of air inside a basketball given its radius. what does v(r) represent? the radius of the basketball when the volume is v the volume of the basketball when the radius is r the volume of the basketball when the radius is v the radius of the basketball when the volume is r

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

the answer should be a. snail
