MAKE SURE TO SHOW WORK FOR ALL QUESTIONS, DO BY HAND!! 1 Matrix addition, scalar multiplication and transpose 5147258369+147258369= What is the transpose of Matrix D ? D=14424912201781 2 Matrix multiplication [720483]091265= 091265[720483]= Explain why the matrix multiplication below is not possible. 722044838[7204]= What is the inverse matrix of A ? A=312203171 B=1392927139 4 Determinant What is the determinant of C ? is C singular ? C=318748168 5 Cross product and normal vector Compute the cross product of v1v2 v1=222v2=843 Let n be the normal vector. Draw v1,v2, and n with respect to each other. Show that the matrix M is non-singular without computing the determinant. M=[v1v2n] 6 Dot product Solve for the angle between v1 and v2 v1=123v2=401
