B) explain how to compute 2 divide 1/4 with a common denominator.

8

Step-by-step explanation:

2 divide 1/4 =

What we have to do here is find a common denominator for both fractions, in this case 4, and change to equivalent fractions with a denominator of 4.

Then we divide across. The denominator of the answer will be 1 because the denominators are the same. Divide the numerators and get 8 ÷ 1, wich is just 8.

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
