Which of the following terms correctly describe the figure given below? Check all that apply.
A. Rectangular solid
B. Pyramid
C. Prism
D. Polyhedron
E. Polygon

A, C, E

Step-by-step explanation:

rectangular solid---the base

prism-2 parallel and congruent bases & lateral faces

polygon- prisms are polygons not polyhedron

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this
