Kindly upload different questions separately. Please rate the answer. Thank you.

Please note that question asks only to state the sequence of transformations hence I have given only the operations and not solved the matrices.

a) i) Rotation about origin by 90 degrees clockwise and then translate in x direction by 2 and y direction by 4.

ii) Rotation about origin by 90 degrees clockwise. Then scale by 0.6667. Then translate by 2 in y direction.

iii) Translate in x direction by 1 and y direction by 1. Then shear in x direction by 2.
