Q:
5. Un trapezio ha l'area di \( 528 \mathrm{~cm}^{2} \) e l'alte:
di 16 cm . Sapendo che le basi sono
unaildoppio dell'altra, calcola la misura
diciascuna di esse. \( \quad \) [ \( 22 \mathrm{~cm} ; 44 \).
Q:
(8. Match the information on the left with the appropriate equation on the right.
An equation perpendicular to
\( y=-3 x+1 \) through the point
\( \begin{array}{l}(3,-2)\end{array} \)
\( y=-3 x+7 \)
An equation through the point \( (-2,3) \)
and parallel to \( y=-3 x-1 \)
\( y=-3 x-3 \)
\( y=\frac{1}{3} x+1 \)
Q:
Match the information on the left with the appropriate equation on the right.
\( \begin{array}{l}\text { An equation perpendicular to } \\ y=-3 x+1 \text { through the point } \\ (3,-2) \\ y=-3 x+7 \\ \text { An equation through the point }(-2,3) \\ \text { and parallel to } y=-3 x-1 \\ y=\frac{1}{3} x-3 \\ y=-3\end{array} \)
Q:
13. Sean el plano \( \pi \equiv 2 x+k y+z-6=0 \) y la recta \( r \equiv\left\{\begin{array}{l}x=2 t \\ y=2+6 t \\ z=2-4 t\end{array}\right. \)
a) ¿Para qué valor de \( k \) la recta es paralela al plano?
b) Para \( k=2 \), halla el ángulo que forman el plano \( \pi y \) la recta \( r \).
Q:
22) Find the exact area of an equilateral triangle whose sides are 8 in.
a) \( 0 \frac{8}{3} \sqrt{3} \mathrm{in}^{2} \)
b) \( 016 \sqrt{3} \mathrm{in}^{2} \)
c) \( 064 \mathrm{in}^{2} \)
d) \( 08 \mathrm{in}^{2} \)
Q:
