Answer: ( -0.731, 0.682)
Step-by-step explanation:
The unit vector is defined as a vector that points in the same direction as our vector (137 degrees from the x-axis) and has a magnitude of 1.
Knowing the angle, is really simple to do it.
First, we know that for a radius R and an angle A, the rectangular coordinates can be written as:
x = R*cos(A)
y = R*sin(A)
And if we want that the magnitude/modulus of our vector to be 1, then R = 1, and we know that A = 137°
x = 1*cos(137°) = -0.731
y = 1*sin(137°) = 0.682
Then the unit vector is: ( -0.731, 0.682)

Answer: C
I hope this helps. Lol I solved it easily. Good luck
Let x be the number of gb used.
Question (1):
Runfast = 10 + 4x
<span>BA&D= 6 + 6x
Question (2):
</span> 10 + 4x = 6 + 6x
2x = 4
x = 2
Both companies will cost the same if you use 2 Gb of data.
BA&D will be cheaper if you use less than 2 Gb of data.
Runfast will be cheaper if you use more than 2 Gb of data.
From what this number to solve it
