![**Instruction: Matrix Multiplication**
Calculate \( Ab_1 \), where \( b_1 \) is the first column of matrix \( B \).
\[ Ab_1 = \boxed{} \]
*(Type an integer or decimal for each matrix element.)*
---
**Explanation:**
To solve this problem, you need to perform matrix multiplication where \( A \) is a given matrix and \( b_1 \) is the first column vector of matrix \( B \). Each element of the resulting vector is obtained by taking the dot product of each row of matrix \( A \) with the column vector \( b_1 \). Ensure to fill the box with appropriate numerical values for each matrix element as required.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F3d31c5b4-c6dc-4739-be04-6ff777f4b60f%2Fb9e66245-de22-4ddd-8445-eb152185a08b%2Foynzc2r_processed.png&w=3840&q=75)
