During last years volleyball season the coach concluded that the number of points scored in each game could be given by the equation x-7=2.how many points were scored in each game?

 The number of points scored by each game is 9

Step-by-step explanation:

The number of points scored in each game given by the equation

x - 7 = 2

x = 2 + 7

 x = 9

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
