Answer:
Option B.
Step-by-step explanation:
Given:
r is a set of rational numbers.
We need to find the reason why r is not a relation.
A relation is a set of ordered pairs, where x-coordinate is domain and y-coordinate is range. It is defined as
Since r is not a set of ordered pairs, therefore r is not a relation.
Thus, the correct option is B.

Answer:
The maximum length is 170 feet and maximum width is 340 feet.
Step-by-step explanation:
Let the length of the parking = x feet and width = y feet.
Since, the fencing is to be applied on three sides of the lot.
So,we get,
i.e.
Since, the area of the rectangular lot = Length × Width
So, area of the lot =
i.e. area of the lot =
i.e. area of the lot =
Now, we know the maximum value of 'x' in is
.
So, the maximum length of the lot is x= =
= 170 feet.
Then, i,plies
implies
i.e. y= 340 feet.
So, the maximum length is 170 feet and maximum width is 340 feet.
