I don't understand this question can you help me pls?

Step-by-step explanation:

1125*3=3375

The first diagram shows how to multiply each number separately instead of the normal way. It shows you in sections instead one line.

The question asks if you started with the first "1" in 1125, will the answer be different. The answer is no.  

since the hundred number given, when multiplied by the 3, will not result in "carrying the 1 over to the thousand place, the answer will not change.

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

a) 0,0; 1,1; and 2,2

step-by-step explanation:

these have the exact same coordinates, thus they are the correct function.
