Can I get some help with this question?
"If C is a 5 x 1 matrix and D is a 3 x 5 matrix, what are the dimensions of DC?"
Answered by Steve
better review matrix multiplication.
pxq * qxr = pxr
So, DC will be 3x5 * 5x1 = 3x1
Note that CD is undefined.

For some reason, my course skipped over matrix multiplication, but Ill look it up online. Thank you.

I find it hard to believe that the course skipped a topic it is assigning for you to do.
