What is the scientific notation for 950?

To find a, take the number and move a decimal place to the right one position.

Now, to find b, count how many places to the right of the decimal.

There are 2 places to the right of the decimal place.

Building upon what we know above, we can now reconstruct the number into scientific notation.

Remember, the notation is: a x 10b

a = 9.5 (Please notice any zeroes on the end have been removed)

b = 2

Now the whole thing:

9.5 x 102

Check your work:

102 = 100 x 9.5 = 950

step-by-step explan mxfcg'k; uafwgzfgjhklhgation:

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
