Answer:
a) Suppose that F is ordered in ascending order: 
. Then, the complement of F can be written as
which is the union of a finite number of open intervals, then 
is an open set. Thus, F is a closed subset of the real numbers.
b) Take an arbitrary element of F, let us say 
. Now, choose a real number 
such that
there are not other element of F, because is less that the minimum distance between and its neighbors.
In case that 
we only consider 
, and if 
we only consider 
.
Then, all points of F are isolated.

Answer:point C
Explanation:A plane and a line can either:
1- have no intersection
2- intersect in a point
3- intersect in a line in case the whole line is found in this plane
For the given:
We can see that line CG does not belong to the plane ABCD, however, they both intersect.
This means that the intersection between them is a point.
We can note that the only point common between the line and the plane is point C.
Therefore, plane ABCD intersects line GC at point C
Hope this helps :)
Answer: A
Step by step: None

The current ratio (assets/liabilities) of company X is 3.1. Given that
the current assets are $186000, find the current liabilities:
Assets = A
Liabilities = L
A / L = 3.1 => L = A / 3.1
A = 186000 => L = 18600 / 3.1 = 6000
Answer: $ 6000
2. The board of directors determines that the current ratio must never
be below 2.6. What is the maximum amount that the company can borrow?
A/L ≥ 2.6
=> L ≤ A / 2.6
=> L ≤ 186000 / 2.6
L ≤ 71538.46
Answer: $71538.46
