Tell which quadrant each of the following points is located in: I, II, III, or IV.
11. (20, 10) -
10. (-9,17) -
9. (15, -12)
13. (30,-8)
12. (-6, -23)
14. (-5.-5)
16. (-14,-2)
17. (-8, 35)
15. (18, 10)
Can anyone help me I did not know how to do it

11.Quadrant 1 10.quadrant II 9. IV 13. IV 12. III 14. III 16: III 17: II 15 I

Step-by-step explanation:

this should help https://socratic.org/questions/what-is-the-order-of-quadrants-in-a-graph  just look at the coordinates x and y if they correspond to which quadrant.

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

one set of data has more variation than the other. hope this !
