party esta enumerando 100 paguinas de su cuaderno de aritmetica. Cuantos digitos (numeros del 0 al 9 utilizo? (por ejemplo: en la paguina 1 , lleva un digito, en la 2 lleva 2 digitos, en la 10 a escrito 11 digitos en el cuaderno.

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

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7
