Answer:

Step-by-step explanation:
We are given that a unit vector A which lies in the xy-plane.
Unit vector:It is that vector whose magnitude is equal to 1.


We have to find the unit vector.
x-component of unit vector=
x-component of unit vector=
y-component of unit vector=
Unit vector ,A=
Hence, the unit vector =
C) -5,-2,1,4,6 is the correct answer
Answer:
b and d
Step-by-step explanation:
parallel means go in the exact same direction and if they never ended, they would never touch
Hello :
<span>Y=x²-2x-19 ...(1)
y+4x=5.....(2)
by (2) : y = 5-4x ....(*)
subsct in (1) : 5-4x</span>=x²-2x-19
x²+2x-24 =0
<span>Δ = 2²-4(1)(-24) = 100=10²
x1 = (-2-10)/2 =-6
x2= (-2+10)/2=4
if : x =-6 by(*) : y= 5-4(-6)=29
if x= 4 y = 5-4(4)=-11
</span><span>solution set system of equation is (-6,29) and (4,-11)______.</span>
I think the cost is less than a dollar. 1 container of soup has 120/3 = 40 bowls
if 1 container costs $30; each bowl costs: 30/40 = $0.75
