For this problem to begin, we know that we create the vector z, which has elements pi, 205, 149, and negative 2.
00:16
So we can see that the length here, we'll just call that n, is equal to 4.
00:22
Then we create the first version of y, where we concatenate z, 555, and then z again.
00:31
So that would mean, let's see here, use some computer wizardry, we'd have pi 205 149 negative 2 555 followed by pi 205 149 and negative 2.
00:58
So now we can see that the length, well we had two versions of z, so those were length 4 plus 4, so that's 8, plus another value so we have a length of 9 in total.

Then for the third line there, we just double y and add 760 to each value...
