B and D

Step-by-step explanation:

PLUG AND CHU

if you don't know what that means, you're just placing the values of x and y into the equation

a) 3=3(1)-1 --> 3≠2

b) 8=3(3)-1 --> 8=9-1 --> 8=8

c) 17=3(7)-1 --> 17=21-1 --> 17≠20

d) 29= 3(10)-1 --> 29=30-1 --> 29=29

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

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:
