Which of the following lists is in order from least to greatest?

|-2|, 4 -1, , 3 × 10 -2
4 -1, 3 × 10 -2, |-2|,
, 3 × 10 -2, |-2|, 4 -1
3 × 10 -2, 4 -1, , |-2|

The last option is the correct one

Step-by-step explanation:

3 x 10^-2 = 0,003

4^-1 = 0.25

√1 = 1

|-2| = 2

so the order if the order is from least to greatest =

3 × 10^-2, 4^-1, √1, |-2|

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

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
