Answer: 1/5, 5
Step-by-step explanation:
hey its -100 percent. the negative to show decrease.
By definition, the unit vector of v = (a,b) is

Therefore,
The unit vector of v₁ = (3,5) in the direction of |v₁| s
(3,5)/√[3² + 5²]
= (3,5)/√34
The unit vector of v₂ in the direction of |v₂| is
(-4,7)/√[(-4)² + 7²]
= (-4,7)/√65
Answer:
The unit vector of v₁ in the direction of |v₁} is

The unit vector of v₂ in the directin of |v₂| is
Slope = (-3 - r) / (2 - 5)
Slope = <span>(-3 - r) / -3 = 4/3
-(-3 - r) = 4
3 + r = 4
r = 4 - 3
r = 1 option b.</span>
