3. How do you add two mixed numbers with like denominators?

Just like the previous answer stated, you must find common denominators to answer. However, that is just part of it.

Note that when you are finding a common denominator, you must multiply what you multiplied to the denominator to the numerator as well. Then, add across. Also note that when adding, you are only adding the numbers of the numerator, the denominator stays the same. For example:

1 4/10 + 3 2/5 = 14/10 + 17/5 = 14/10 + (17/5)(2/2) = 14/10 + 34/10 = 48/10.

48/10 = 4 8/10

  n=   0.0000 - 0.3750 i  

  n=   0.0000 + 0.3750 i

step-by-step explanation:

one of these should be correct

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
