Help The function, f, gives the number of copies a book has sold w weeks after it was published. The equation f(w) = 500 * 2w defines this function.

Select all domains for which the average rate of change could be a good measure for the number of books sold.

a 0 ≤ w ≤ 2
b 0 ≤ w ≤ 7
c 5 ≤ w ≤ 7
d 5 ≤ w ≤ 10
e 0 ≤ w ≤ 10

2,600 divided by 80 = 32.5

step-by-step explanation:

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

there would only be 50 odd numbers between 1 and 100 so therefor there would be 50 even so that would only be 50 odd numbers.
