Write an inequality for the sentence
then solve.
fifteen less than a number is at most 6

a. x+15< (with a line under it)6; x< (with a line under it)-9**
b. x-15< (with a line under it)6; x> (with a line under it) 21
c. x-15 > (with a line under it)6; > (with a line under it)21
d. x-15> (with a line under it)6; x> (with a line under it)16

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

b. hoped i'm right lol
