Q. Consider these matrix transformations:A=[−4−4−12]B=[1441]This is the result of composing A∘B, with the first column missing.[xy−17−14]Find the missing values.x=y=
Given Matrices A and B: We are given two matrices A and B, and the result of their multiplication A@B with the first column missing. We need to find the missing values x and y in the first column of the resulting matrix.A=[[−4,−1],[−4,2]]B=[[1,4],[4,1]]The resulting matrix after A@B is given as:[[x,−17],[y,−14]]To find x and y, we need to perform the matrix multiplication A@B and look at the first column of the result.
Calculating x: First, let's calculate the element in the first row and first column of the resulting matrix A@B. This is done by taking the dot product of the first row of A with the first column of B: (−4)⋅1+(−1)⋅4=−4−4=−8 So, x=−8.
Calculating y: Now, let's calculate the element in the second row and first column of the resulting matrix A@B. This is done by taking the dot product of the second row of A with the first column of B: (−4)⋅1+2⋅4=−4+8=4 So, y=4.
