PLEASE HELP IM STUCK!!question 1: solve 2x^2 - 6x + 10 = 0 by completing the square. question 2: solve x^2 - 3x = -8 using the quadratic formula.
question 3: select the graph that can be used to find the solution(s) of the system of equations. y = -|x+3| - 4 , y = -1/2x - 7

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

6 on both sides and twelve on the top and the bottom
