The vector \vec{A} has x,y,z components of 7, 9, and -2 units respectively. Obtain the unit vector notation expression for \vec{A}. \vec{A} = \boxed{}\hat{i} \boxed{}\hat{j} \boxed{}\hat{k} Obtain the unit vector notation expression for a new vector named \vec{B} which is 0.25 the length of \vec{A}, and pointing in the same direction. \vec{B} = \boxed{}\hat{i} \boxed{}\hat{j} \boxed{}\hat{k} Obtain the unit vector notation expression for a new vector named \vec{C} which is 3 times the length of \vec{A}, and is pointing in the opposite direction. \vec{C} = \boxed{}\hat{i} \boxed{}\hat{j} \boxed{}\hat{k}

1. An affine transformation $T: \mathbb{R}^n \to \mathbb{R}^m$ has the form $T(x) = Ax + b$, with $A$ an $m \times n$ matrix and $b$ is in $\mathbb{R}^m$. Show that $T$ is linear if and only if $b = 0$. 2. Let $T: \mathbb{R}^n \to \mathbb{R}^m$ be a linear transformation, and let \{$v_1, v_2, v_3$\} be linearly dependent. Is the set \{$T(v_1), T(v_2), T(v_3)$\} linearly dependent? Explain why or why not
