Which set of ordered pairs represents a function? {(5, -8), (8,-1), (8,7), (-4,2)}

{(-9,-9), (7, -9), (-7, -7), (9,-8)}

{(4,7), (-7,-4), (6,8), (-7,6)}

{(0,8), (-7,2), (4, -9), (4, -3)}

The second one

Step-by-step explanation:

That's the only set where there is only one output for every input.

honeycrisps have skyrocketed to about $4.50 per pound

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
