Find the Euclidean distance between $\mathbf{u}$ and $\mathbf{v}$ and the cosine of the angle between those vectors. State whether that angle is acute, obtuse, or $90^{?}.\mathbf{u}=(?5,6,?1,1),\mathbf{v}=(?7,9,0,?4)$. NOTE: Enter the exact answer or round the exact answer to two decimal places. $d(\mathbf{u},\mathbf{v})?$ NOTE: Enter the exact answer. $\cos ?=$ The angle is Find the Euclidean distance between $u$ and $v$ and the cosine of the angle between those vectors. State whether that angle is acute, obtuse, or $90^{?}?u=(?5,6,?1,1),v=(?7,9,0,?4)$. NOTE: Enter the exact answer or round the exact answer to two decimal places. $d(\mathbf{u},\mathbf{v})?$ NOTE: Enter the exact answer. $\cos ?=$
