Answer :
Let's analyze and solve this problem step-by-step.
### 2-Letter Word: "AM"
1. Determine the grid size: We are working with a grid of size 40.
2. Word length: "AM" is 2 letters long.
3. Calculate the number of repetitions: The grid size (40) divided by the word length (2) equals 20. Thus, "AM" can be written 20 times in the grid.
4. End positions: Since "AM" is written 20 times, the end positions occur at each multiple of 2, i.e., 2, 4, 6, 8, ..., 40.
Hence, for the 2-letter word "AM," it is written 20 times, and the numbers with the end letter are:
[tex]\[ 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40 \][/tex]
### 3-Letter Word: "CAT"
1. Word length: "CAT" is 3 letters long.
2. Calculate the number of repetitions: The grid size (40) divided by the word length (3) yields another basis for calculation. While 40 ÷ 3 ≈ 13.33, we only consider whole numbers, so we take 13 as the number of full repetitions.
3. End positions: Since "CAT" is written 13 times, the end positions occur at each multiple of 3, rounding down for the final repetition: 3, 6, 9, 12, ..., 39.
Thus, for the 3-letter word "CAT," it is written 13 times, and the numbers with the end letter are:
[tex]\[ 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39 \][/tex]
### 4-Letter Word: "BIRD"
1. Word length: "BIRD" is 4 letters long.
2. Calculate the number of repetitions: The grid size (40) divided by the word length (4) equals 10. Thus, "BIRD" can be written 10 times in the grid.
3. End positions: Since "BIRD" is written 10 times, the end positions occur at each multiple of 4: 4, 8, 12, 16, ..., 40.
Therefore, for the 4-letter word "BIRD," it is written 10 times, and the numbers with the end letter are:
[tex]\[ 4, 8, 12, 16, 20, 24, 28, 32, 36, 40 \][/tex]
Summarizing:
- For the 2-letter word "AM": Repetitions = 20, End positions = [tex]\( 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40 \)[/tex]
- For the 3-letter word "CAT": Repetitions = 13, End positions = [tex]\( 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39 \)[/tex]
- For the 4-letter word "BIRD": Repetitions = 10, End positions = [tex]\( 4, 8, 12, 16, 20, 24, 28, 32, 36, 40 \)[/tex]
These calculations reflect how the words can be written throughout the grid and identify the positions at which each repetition ends.
