Answer:
C. None of the above
Step-by-step explanation:
The formula for the perimeter of a square is P=4a where "P" is the perimeter and "a" is for the length of the side. In this problem, the perimeter is given which is equal to 12 units, then we can solve for the distance or length of the side which is shown below:
P=4a
12=4a
a=3 units
The answer is (2,1) and proof of this is the distance should be equal to 3 units
at the vertex (2,4)
d²=(2-2)²+(4-1)²
d²=0²+3²
d=3 units
Hence, answer is (2,1)
Answer:
- A → B: 1/3
- correct
- A → B: 2/5
Step-by-step explanation:
It is clear from your answer to the second part that you know the A→B scale factor is the reciprocal of the B→A scale factor. Use that fact for the other two parts of the question.
- A → B = 1/3; B → A = 3
- A → B = 2; B → A = 1/2
- A → B = 2/5; B → A = 5/2

It is convenient to find a unit length (or the smallest length) on the smaller figure, then see how much that is multiplied by to get the larger figure.
- B : A = 1 : 3
- A : B = 1 : 2
- B : A = 2 : 5
Once you have these ratios, you need to determine what the notation A→B is supposed to mean. Here, we presume it means B/A.
