Tell whether the relation is a function. Explain your reasoning.

5 0

The relation is not a function. In order for a relation to be a function, the x-inputs of all ordered pairs must not repeat, and if they do, they must have only one output. In this problem, however, (9,4) and (9,1) both have different outputs (y-values). Therefore, there is no function present.

Answer:

We are given an area and three different widths and we need to determine the corresponding length and perimeter.

The first width that is provided is 4 yards and to get an area of 100 we need to multiply it by 25 yards. This would mean that our length is 25 yards and our perimeter would be 2(l + w) which is 2(25 + 4) = 58 yards.

The second width that is given is 5 yards and in order to get an area of 100 yards we need to multiply by 20 yards. This would mean that our length is 20 yards and our perimeter would be 2(l + w) which is 2(20 + 5) = 50 yards.

The final width that is given is 10 yards and in order to get an area of 100 yards we need to multiply by 10. This would mean that our length is 10 yards and our perimeter would be 2(l + w) which is 2(10 + 10) = 40 yards.

Therefore the field that would require the least amount of fencing (the smallest perimeter) is option C, field #3.

Hope this helps!

43 + 49= 92.

Then 180 - 92= 88

C= 88
