Final Answer:
The dimensions of the matrix is option: C) 5x7
Explanation:
To determine the dimensions of the matrix, we need to consider the number of rows and columns. The given options present different combinations, and we can eliminate choices based on the mismatch of rows and columns.
Starting with option A (7x4), we see that it has 7 rows and 4 columns. Moving on to option B (10x3), we find 10 rows and 3 columns. Option D (9x6) consists of 9 rows and 6 columns. However, none of these options match the common convention of specifying matrices, where the first number represents the number of rows and the second number represents the number of columns.
Finally, considering option C (5x7), we find that it has 5 rows and 7 columns. This conforms to the standard notation for matrix dimensions. Therefore, the correct answer is C) 5x7.
In summary, by evaluating each option and comparing the number of rows and columns, we identify that option C is the only one with the appropriate matrix dimensions, 5x7.
