What is the profit function, $p(x)$, when the revenue function is $r(x) = 20x$ and the cost function is $c(x) = x^2 - 1100x + 1200$?
What is the profit function, $p(x)$, when the revenue function is $r(x) = 20x$ and the cost function is $c(x) = x^2 - 1100x + 1200$?
- $p(x) = -x^2 + 1120x - 1200$ (correct)
- $p(x) = x^2 - 1120x - 1200$
- $p(x) = -x^2 - 1120x + 1200$
- $p(x) = x^2 + 1120x - 1200$
What is the product of $f(x) = x^2 + 2x - 5$ and $g(x) = 3x - 1$?
What is the product of $f(x) = x^2 + 2x - 5$ and $g(x) = 3x - 1$?
- $3x^3 - 5x^2 + 17x - 5$
- $3x^3 - 5x^2 - 17x - 5$
- $3x^3 + 5x^2 + 17x + 5$
- $3x^3 + 5x^2 - 17x + 5$ (correct)
What is the result of dividing $g(x) = 4x^5$ by $h(x) = 8x^2$?
What is the result of dividing $g(x) = 4x^5$ by $h(x) = 8x^2$?
- $0.5x^{3}$ (correct)
- $2x^{7}$
- $2x^{3}$
- $0.5x^{7}$
