PLS HELP ME ON THIS IT IS VERY URGENT FOR MY TEACHER I NEED THIS IN TOMMOROW THANK YOU

a) A b)C c)A

Step-by-step explanation:

a) the parabola is flipped upside down so it has to be -a

b) +c moves the parabola up, -c moves the parabola down

c) the x-intercepts are both negative, making the solution negative

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
