[Solved] What will be the output of this code?import numpy as np from scipy.linalg import det B = np.array([[1, 2, 3], [4, 5, 6], [7, 8, 9]]) print(round(det(B), 2)) | SciPy

SciPy - Linear Algebra (scipy.linalg)

What will be the output of this code?

import numpy as np
from scipy.linalg import det
B = np.array([[1, 2, 3], [4, 5, 6], [7, 8, 9]])
print(round(det(B), 2))

A45.0

B0.0

C15.0

D1.0

Step-by-Step Solution

Solution:

Step 1: Recognize matrix pattern
Matrix B has rows that are linearly dependent (third row is sum of first two).
Step 2: Determinant of dependent rows
Determinant is zero if rows are linearly dependent.
Final Answer:
0.0 -> Option B
Quick Check:
Dependent rows -> determinant zero [OK]

Quick Trick: Dependent rows mean determinant zero [OK]
