. The function V (s)=30.094s can be used to find the approximate volume of a sphere (V, in cubic units) in
terms of its surface area (s, in square units). If the
volume of a soccer ball is 1,930. 75 cubic centimeters,
what is the surface area of the soccer ball to the nearest
square centimeter?

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 correct answer is $7.38
