Dar un ejemplo de una competencia de velocidad donde se evidencie egún los tiempos dados como quedan clasificados del primero al último.

Q2) Solve the following questions. (a) Find the terminal point of the vector that is equivalent to \( \mathbf{u}=(1,2) \) and whose initial point is \( A(1,1) \). (b) Find the initial point of the vector that is equivalent to \( \mathbf{u}=(1,1,3) \) and whose terminal point is \( B(-1,-1,2) \).

Example: Which data set has the greater variability? Explain how you know. Set A: \( 35,75,23,89,67,67,23,23,22,74 \) Set B: \( 20,25,23,22,24,23,23,21,22,24 \)

7. \( \lim _{x \rightarrow-2} \frac{7 x^{3}+14 x^{2}}{14 x^{2}+28 x}= \)

\( \left. \begin{array} { c c } { - A = \left( \begin{array} { c c c } { 3 } & { 1 } & { 3 } \\ { - 1 } & { 0 } & { - 1 } \\ { 2 } & { 5 } & { 3 } \end{array} \right) } & { B = \left( \begin{array} { c c c } { 7 } & { 3 } & { - 1 } \\ { 2 } & { 8 } & { 7 } \\ { - 1 } & { - 2 } & { - 3 } \end{array} \right) } \\ { A \times B } & { A + B } \\ { B \times A } & { B - A } \end{array} \right. \)

Write the expression as a product. Simplify your answer if necessary. \( \sin 3 t+\sin 9 t=\square \)
