5. if t is a linear transformation such that dim im(t) = 5 dim ker(t) = 2 then can we determine dim dom(t)? hint: we learned that all these subspaces can be understood as certain subspaces associated to the standard matrix of t.

Yes, we can determine dim Dom(T).

Step-by-step explanation:

We are given that if T is  a linear transformation such that

dim Im(T)=5

Dim Ker(T)=2

We have to tell that we can determine   dim Dom(T)

Rank-nullity theorem:

Substitute the values then we get

Dim Dom(T)=7

Hence, we can determine dim Dom(T) by using rank- nullity theorem.
