Which of the following is a polynomial with roots - A)x3 − 2x2 − 3x + 6
B)x3 + 2x2 − 3x − 6
C)x3 − 3x2 − 5x + 15
D)x3 + 3x2 − 5x − 15

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

i belive those are the ones that are under 90 degreese.

my guess is
