The volumes of two similar solids are 1331 m3 and 343 m3. the surface area of the larger one is 484 m2. what is the surface area of the smaller one? 196 m2 1372 m2 343 m2 none of these

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

its a trick question
