Question: For the vectors, vec ( A ) = 3 hat ( ) - 2 hat ( ) + 4 hat ( k ) , vec

For the vectors, vec(A)=3hat()-2hat()+4hat(k),vec(B)=-5hat()+3hat()+4hat(k), and vec(C)=-1hat()-6hat()+2hat(k) do the following calculations by hand:
10. Compute the magnitude of vec(A)
vec(A)=3hat(i)-2hat(j)+4hat(k)
(3)2-(2)2+(4)22
292=5.38516
Magnitude of vec(A)~~5.4
11.
Compute vec(A)-3vec(B)+2vec(C)
vec(A)=3hat(i)-2hat(j)+4hat(k)
-3vec(B)=-15hat(i)+9hat(j)+22hat(k)
+2vec(c)=-2hat(i)=12hat(j)+4hat(k)
16hat(i)-23hat(j)-4hat(k)
Compute vec(C)**vec(B)
C=-1hat(i)-6hat(j)+2hat(k)
=-5hat(i)+3hat(j)+4hat(k)
5+18+8=-5
