Explanation:
<u>Question 1</u>
At $5 = $3750 revenue
At $17 = $2500 revenue
Hence, at $5 the revenue is more.
<u>Question 2</u>
Looking at the vertex (maximum point of the curve), we can identify that the company should sell their products at cost of $10 by which they will make a revenue of $5000.
<u>Question 3</u>
Domain lies in the x axis of the graph. Here the domain:
0 ≤ x ≤ 20
Question says to draw a polygon with the given conditions in a coordinate plane. It is talking about Rectangle with perimeter of 20 units.
So we can use formula of perimeter of rectangel to find it's possible dimensions.
We knwo that perimeter of the rectangle is given by 2(L+W)
where L is lenght and W is width.
Given perimeter is 20 so we get:
2(L+W)=20
L+W=10
L=10-W
So basically we can use any number for W which can be from 0 to 10 as side length can't be negative.
Let W=4
Then L=10-W=10-4=6
Hence we just have to draw a rectangle having length 6 and width 4.
So the final answer will be picture in the attached graph.
