Squares maybe, do 40 across 2 down to form a rectangle add them up then it will give you 40*2
The function that has the same set of potential rational roots is
<span>4(3x5-2x4+9x3-x2+12). If you see it from your options I know this is the one who is closer to the same set you are looking for. </span>
Answer:
b
Step-by-step explanation:
Answer:
(a) The daily total revenue realized from the sale of 210 units of the toaster oven is $6,195.
(b) The additional revenue realized when the production (and sales) level is increased from 210 to 310 units is $1,400.
Step-by-step explanation:
The marginal revenue gives the actual revenue realized from the sale of an additional unit of the commodity given that sales are already at a certain level. The derivative <em>R'</em> of the function <em>R</em> measures the rate of change of the revenue function.
We know that the daily marginal revenue function is given by

(a) To find the the daily total revenue you must:
- Integrate the daily marginal revenue function,
,
where C is a constant.
- Find the value of C, using the fact that if you sell 0 units your daily revenue is $0.


The daily total revenue realized from the sale of 210 units of the toaster oven is
x = 210 units

(b) To find the additional revenue realized when the production (and sales) level is increased from 210 to 310 units you must:
- Find the daily total revenue realized from the sale of 310 units

The additional revenue realized when the production (and sales) level is increased from 210 to 310 units is

W= width
l= 2w= length
Perimeter of a Rectangle Formula
P= 2(l + w)
substitute 2w for l in equation
180= 2(2w + w)
multiply 2 by parentheses
180= 4w + 2w
combine like terms
180= 6w
divide both sides by 6
30 yards= w
LENGTH
2w= 2(30)= 60 yards
CHECK:
180= 30 + 60 + 30 + 60
180= 90 + 90
180= 180
ANSWER: the width is 30 yards and the length is 60 yards
Hope this helps! :)
