Answer:
it will be 19, 23, 27
Step-by-step explanation:
all you have to do is check the pattern the sequence uses to progress. in this sequence it increases by adding 4 to a previous number.
so;
3 + 4= 7
7 + 4= 11
11 + 4= 15... and so on
i hope this helps
The answer to your question is b.
So you are gonna have to subtract the area with the numbers given and round that answer to the the nearest 1/10! I hope this answers your question... or helps you solve it!!!!!
Answer:
The correct answer is 0.5 pounds of pollutant.
Step-by-step explanation:
According to the problem the cost of controlling emissions at a firm is given by:
C(q) = 1,260 + 100 × 
, where q is the reduction in emissions (in pounds of pollution per day) and C is the daily cost to the firm (in dollars) of this reduction.
Government clean-air subsidies amount to $100 per pound of pollutant removed per day.
Net cost = C(q) - Subsidy
⇒ Net Cost = 1,260 + 100 × - 100 × q.
In order to minimize net cost we calculate, 
(Net cost) = 0.
⇒ 200 × q - 100 = 0
⇒ q = 0.5
We can see that the second order derivative is positive and thus the net cost minimizes.
Thus the firm should remove 0.5 pounds of pollutant each day in order to minimize net cost.
It has to do with the number of dimensions you have in the figure. For example, in a square you have 2 dimensions, length and width. Since you have only two you use units^2. In a cube, you have 3 dimensions, length, width and height, which is where you get the units^3.
