Look at the expression below.
expression 1: x-x
expression 2: -2+4/2
expression 3: 1/4+.25
expression 4: -1//5)
zion made a mistake when using the inverse property of addition to generate equivalent expressions. which expression shows the mistake zion made?

Step-by-step explanation:

so in the inverse property of addition, the sum will equal 0

mistake is in expression 3.

1/4 + 0.25should be  1/4 + (-0.25)

what?

step-by-step explanation:

what do you need with. i love quadrants. can you tell me ?

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
