Determine rhe integer whose product us with(-1) is. -125​

x = 125

Step-by-step explanation:

a × 1 = a

a × (- 1) = -a

- a × (- 1 ) = a

Let the integer be x

Product with  - 1 is -125, that is

                                      = x × ( - 1 ) = - 125

Solve for x

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
