The revenue from manufacturing and selling x units of toaster ovens is given by:

nexus9112 [7]

Answer:

$248,000.

Step-by-step explanation:

We have been given that the revenue from manufacturing and selling x units of toaster ovens is given by $R(x)=-0.3x^2+200x-82,000$ .

To find the amount of revenue earned from selling 3,000 toaster, we will substitute $x=3,000$ in the given formula as:

$R(3,000)=-0.03(3,000)^2+200(3,000)-82,000$

$R(3,000)=-0.03*9,000000+600,000-82,000$

$R(3,000)=-270,000+518,000$

$R(3,000)=248,000$

Therefore, the company should expect revenue of $248,000 from selling 3,000 toaster ovens.

Find the distance between the points (5, -6) and (-1, 3).

emmasim [6.3K]

Answer:

$\sqrt{117}$

Step-by-step explanation:

Use the distance formula.

$d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

$d = \sqrt{(-1 - 5)^2 + (3 - (-6))^2}$

$d = \sqrt{(-6)^2 + 9^2}$

$d = \sqrt{36 + 81}$

$d = \sqrt{117}$
