Describe cómo se puede representar un cubo mediante un diagrama de red. ¿Cuántas caras tiene un cubo y cuál es la forma de cada cara?

(1) Find parametric equations for the line through the point \( (-6,1,2) \) and the point of intersection line \( \frac{x+4}{1}=\frac{y-1}{-2}=\frac{z}{5} \) with plane \( x-3 y+2 z=10 \)

Q2: \( (8 \) Marks) For the points, \( P(0,1,-1), Q(1,2,0) \), and \( R(1,3,2) \) : A- If \( u=\overline{P Q} \) and \( v=\overline{P R} \), find the vector projection of \( u \) onto \( v \), and the scalar component of \( u \) in the direction of \( v \). B. Find the area of the triangle with vertices \( P, Q \), and \( R \).

Geometric Mean of 4,2 and 8 is? Select one: a. -2 b. 0 c. 4 d. 9

Q2: (10. Marks) Find the distance from the point A to the line through points B and C . Then show that the triangle whose vertices points \( \mathrm{A}, \mathrm{B} \) and C is right triangle and find its area. Where: \( A(3,3,-4), B(0,5,1) \) and \( C(2,1,-2) \).

What do we call the distance around a circle?
