Mason says that 350 + 2 x 104 can be written in scientific notation as 55 x 104 Is Mason correct?
Explain your answer using mathematics,

Mason's affirmation is:

Step-by-step explanation:

The first form you can see that Mason is wrong is operating:

How the two operations didn't have the same result, the second form isn't a scientific notation of the first form.

The second case is because a scientific notation regularly is written in the next form:

I used the result (558) then ubicate the point in the units (5) and the rest  are decimals, next I used 10 and the number of digits that I moved the point (2).

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°
