) Een zwembad bevat 10000 US gallons. Hoeveel \( m^{3} \) is dat

a) Is the following set of vectors in \( \mathbb{R}^{4} \) linearly dependent, if yes, write the first vector as a linear combination of the other vectors. \( S=\{(1,2,-3,1),(3,7,1,-2),(1,3,7,-4)\} \).

12. Find a standard basis vector for \( R^{3} \) that can be added to the set \( \left\{\mathbf{v}_{1}, \mathbf{v}_{2}\right\} \) to produce a basis for \( R^{3} \). (a) \( \mathbf{v}_{1}=(-1,2,3), \mathbf{v}_{2}=(1,-2,-2) \) (b) \( \mathbf{v}_{1}=(1,-1,0), \mathbf{v}_{2}=(3,1,-2) \)
