17 A soccer coach bought 3 timos as many T-shirts as soccer balls, Each soccer ball cost \( \$ 11.50 \) more than oach T-shirt. Ho pald a total of \( \$ 168,60 \). He pald \( \$ 31.50 \) more for all the T-shifts than all the soccer balls. How much did the coach pay for a soccer boll?

The following function is given. \( f(x)=3 x^{3}-7 x^{2}-75 x+175 \) a. List all rational zeros that are possible according to the Rational Zero Theorem. Choose the correct answer below.

\( \left.\begin{array}{l}\left.\text { 1) } \begin{array}{l}\left(4 x^{2}+5\right)\left(x^{2}-2\right)\left(x^{2}+2\right)=0 \\ \text { A) }\left\{\begin{array}{l}i \sqrt{5} \\ 2\end{array}-\frac{i \sqrt{5}}{2}, \sqrt{2},-\sqrt{2}, i \sqrt{2},-i \sqrt{2}\right. \\ \text { B) }\left\{\frac{i \sqrt{10}}{2},-\frac{i \sqrt{10}}{2}, \sqrt{2},-\sqrt{2}, i \sqrt{2},-i \sqrt{2}\right.\end{array}\right\} \\ \text { C) }\left\{\frac{i \sqrt{15}}{3},-\frac{i \sqrt{15}}{3}, i \sqrt{3},-i \sqrt{3}, i \sqrt{2},-i \sqrt{2}\right.\end{array}\right\} \)

\( 1 \leftarrow \quad \) Given vectors \( \mathbf{u} \) and \( \mathbf{v} \), find (a) \( 7 \mathbf{u} \) \( \mathbf{u}=6 \mathbf{i}, \mathbf{v}=3 \mathbf{i}+6 \mathbf{j} \) (b) \( 7 \mathbf{u}+2 \mathbf{v} \) (c) \( \mathbf{v}-2 \mathbf{u} \).
