Answer:
The answer is 6.
Step-by-step explanation:
In order to determine the answer, we have to know about notation numbers. In any number, every digit has a notation, depending on its position.
I have attached an image that shows some notation numbers.
We can see that the nearest tenth position corresponds to the first decimal digit, to the right of the decimal point.
To round the number, first we have to see where is the position where we want to cut the number. Then we have to see the number to the right of the cut position. The rule says:
- If the number is equal or greater than 5, so the number to the left of the cut position will be increase one digit.
- If the number is lesser than 5, so the number to the left of the cut position will not change.
In this case, the number to the right of the cut position is 8, so we have to increase the number to the left of the cut position, 9, in one digit.
Finally, the number 5.9876 rounded to the nearest tenth is 6.

Answer:
2500 Square meters
Step-by-step explanation:
Given the garden area (as a function of its width) as:
The maximum possible area occurs when we maximize the area. To do this, we take the derivative, set it equal to zero and solve for w.
A'(w)=-2w+100
-2w+100=0
-2w=-100
w=50 meters
Since Marquise has 200 meters of fencing to build a rectangular garden,
Perimeter of the proposed garden=200 meters
Perimeter=2(l+w)
2(l+50)=200
2l+100=200
2l=200-100=100
l=50 meters
The dimensions that will yield the maximum area are therefore:
Length =50 meters
Width=50 meters
Maximum Area Possible =50 X 50 =<u>2500 square meters.</u>
