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.

Please please help me with this

Pavlova-9 [17]

Answer:

140

Step-by-step explanation:

Area of a rhombus = GE * HF / 2

Since, ED = 10, GE = 2* ED. SO, GE = 20

Since, FD = 7, HF = 2*FD. SO, HF = 14

So, 20 * 14/2

=> 10 * 14

=> 140
