The graph of the revenue function f(x) = –0.07x2 + 3.5x is used to determine revenue in hundreds of thousands of dollars, where revenue depends on the number of thousands of items sold, x. How do the mathematical domain and reasonable domain compare? mathematical: –∞ < x < ∞ reasonable: 0 ≤ x ≤ 25 mathematical: –∞ < x < ∞ reasonable: 0 ≤ x ≤ 50 mathematical: 0 < x < ∞ reasonable: 0 ≤ x ≤ 25 mathematical: 0 < x < ∞ reasonable: 0 ≤ x ≤ 50

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,
