Leticia simplified an expression. Her work is shown below. 4.5 divided by 0.25 + 2.5 minus 0.75 times 8 Step 1 18 + 2.5 minus 0.75 times 8 Step 2 18 + 1.75 times 8 Step 3 18 + 14 Step 4 32 In which step did Leticia make her first mistake? step 1 step 2 step 3 step 4

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°
