ciao a tutti, qualcuno ha le soluzioni del libro delle vacanze PostIt 2 matematica e scienze? grazie mille. hello everyone, does anyone have the solutions from the PostIt 2 math and science holiday book? thanks a lot. ​

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 to your question is c.)   volcanoes built the mountains and earthquakes tore them down.
