EsERCIzIO 12.13 Trovare una retta passante per \( A(3,1,-2) \), sghemba con \( r \) : \( \left\{\begin{array}{l}x=3+t \\ y=-t \\ z=-2-2 t\end{array}\right. \) e che sia parallela al piano \( \pi:\left\{\begin{array}{l}x=1-t+t^{\prime} \\ y=3 t^{\prime} \\ z=-t-2 t^{\prime}\end{array}\right. \) ANTONIO CIGLIOLA

Find the equation of line perpendicular to \( 5 x-3 y+4=0 \) that passes through the point \( (-4,1) \).

Angles 3 and 5 are \( \square \) and \( m \angle 5 \) is \( (2 x+11)^{\circ} \).

13. Una lámpara está instalada en lo alto de un poste de 15 pies de altura. Un hombre de 6 pies de estatura se aleja caminando desde el poste con una rapidez de 5 pies/s a lo largo de una trayectoria rectilínea. ¿Qué tan rápido se desplaza la punta de su sombra cuando el hombre está a 40 pies del poste?

4.4 \( g \) is one of the axes of symmetry of \( f \) and it is a decreasing function. Determine the equation of \( g \). 4.5 \( (-3 ; 2) \) is a point on \( f \). Determine the coordinates of the image of this point after reflection in \( g \).
