What is the description of the pattern in the sequence? 5, 10, 20, 40, 80,...

The pattern is to multiply by 5.

The pattern is to add 5.

The pattern is to add 2.

The pattern is to multiply by 2.

the pattern is to multiply by 2

Step-by-step explanation:

5 * 2 = 10 * 2 = 20 *2 = 40 * 2 = 80

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
