Answer L×W=A 6 x 2 =12. Step-by-step explanation: length ×weight =area example:you need to measure a full sheet pan and let's say if it is 8 full sheet pan you weighs 23 so you want to multiply 8×23=184 that is your area okay 2×3=6 and 2×1=2 so to figure out the area multiply 6×2=12 so the answer is matrix B just remember length times weight equal areas Itis because the product of mn can be obtained by more than 1 ways, some of them are listed below: mn × 1. 1 × mn. m × n. n × m. For example: Consider the number of elements present in a matrix to be 12. Thus the order of a matrix can be either of the one listed below: \ (\begin {array} {l}12 \times 1\end {array} \) , or. Theinverse of a matrix is that matrix which when multiplied with the original matrix will give an identity matrix. The inverse of a matrix exists only if the matrix is non-singular i.e., the determinant should not be 0. Using determinant and adjoint, we can easily find the inverse of a square matrix using the below formula, Also when you define A like. A = np.array([[1],[0]]) this creates a 2x1 vector (not 1x2). So if you want to multiply the vector A with the matrix B (2x2) this should be C = B*A, where C will be a 2x1 vector . C = B@A Otherwise if you want to multiply A*B and B is still the 2x2 matrix you should define A as a 1x2 vector: A = np.array([1,0]) Conventionalpolynomial multiplication uses 4 coefficient multiplications: (ax + b) (cx + d) = acx 2 + (ad + bc)x + bd. However, notice the following relation: (a + b) (c + d) = ad + bc + ac + bd. The rest of the two components are exactly the middle coefficient for the product of two polynomials. Therefore, the product can be computed as: 06 Matrix Addition and Scalar Multiplication; 07) Practice on Scalar Multiplication, Zero Matrix; 08) Problems Similar to Homework; 09) Problems Similar to Homework 2; 10) Problem from Homework; Chapter 2.2 Matrix Multiplication; 01) Introduction; 02) Vector Multiplication-2 Examples; 03) Vector Mult: (Cont'd) 04) Vector Mult: Practice; 05 youcan multiply a 2x3 matrix by which matrix? danish frikadeller recipe / dj parties in bangalore tomorrow / you can multiply a 2x3 matrix by which matrix? Therule I've been following is this: the dimensions of the matrix are 2x1 and 2x2. The matrix cannot be multiplied if the inside two number (1 for the left column and 2 for the right column) are not the same, because the sizes of the two matrices being multiplied must be m x n and n x p . But my textbook is showing a valid answer for a ZT9Pf.
