There would be 2 raised to c elements in the power set. Elements of the
power set are formed by making a binary decision on each element of the input
set: include or do not include. Since there are two choices for each element of
the input set, and there are c elements in the input set, there are 2^c possible
arrangements of these input elements.
Answer:
Note that the ratio 12 to 3 is said to be equivalent to the ratio 4 to 1, that is 12:3 = 4:1.

In the attached diagram you can see the graph of the function 
As you can see graph is:
1. increasing from x = −2 to x = −1
2. decreasing from x = 0 to x = 1
3. decreasing and then increasing from x=1 to x=2
4. increasing from x=2 to x=4.
Answer: correct choice is B.
Answer:

Step-by-step explanation:
we know that
In this problem ABCD is a rectangle
so
DC=AB
BC=AD
Let
BC ---> the length of rectangle
DC ---> the width of rectangle
we know that
The perimeter of rectangle is equal to

we have

so

simplify
----> equation A
----> equation B
substitute equation B in equation A

Solve for BC
Combine like terms

Divide by 3 both sides

<em>Find the value of DC</em>
----> 
Remember that
DC=AB
therefore
