QUICK The temperature was -20.5°F at 5 A. M. and rose 5 degrees per hour for the next 5 hours. Melissa says the temperature at 10 A. M. was -5.5°F. Which statement identifies Melissa’s error and the correct answer? A. Melissa multiplied incorrectly. The correct answer is -0.5°F. B. Melissa multiplied incorrectly. The correct answer is 9.5°F. C. Melissa added incorrectly. The correct answer is 4.5°F.

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°
