population in 2010 was approximately 790,000, what is the predicted
population for 2020?
Predicted population for 2020:

2.The population of Boston, Massachusetts, is growing at a rate of 1.8% annually.
The population in 2013 was approximately 636,500. What is the predicted
population for 2025?
Predicted population for 2025:

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°
