Whats The Correct Answer To My Question ?

7.527

Step-by-step explanation:

We know that 78% of the bar is gold and the total weight is 9.65 ounces. Just multiply the total weight by 78%.

9.65(0.78)= 7.527

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

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1
