Which of the following relations is a function? A. (0, 4), (-2, 6), (0, 3), (-7, 2) B. (8, 1), (-2, 4), (0, 1), (8, 2) C. (0, 4)
fomenos
Answer: C
Step-by-step explanation:
C is a function because each of the inputs are distinct, meaning they only have one output each.
The other choices are not functions because at least one of the inputs corresponds to 2 or more outputs.
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>
C is the answer to that question i think
Answer:
140 miles
Step-by-step explanation:
1 times 20 (1 inch=20 miles)
2 times 20 (2 inches=40 miles)
3 times 20 (3 inches=60 miles)
4 times 20 (4 inches=80 miles)
5 times 20 (5 inches=100 miles)
6 times 20 (6 inches=120 miles)
7 times 20 (7 inches=140 miles)
Hope this helped!! :)
