If a=-2 and b=-3 and c=2 and x=2.1 and y =3 and z=-4.2 what is the this answer? 4a-| 3b - 8c | -3

-36

Step-by-step explanation:

plug in the letters for the numbers, then you get, -8 - 25 - 3.  -8 - 25 is -33, then you subtract that to 3. so it should look like, -33 - 3.  then simplified even more is -36.

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
