Answer:
6-1/0-1=5/-1
Step-by-step explanation:
change in y over change in x gives you gradient.therefore the gradient is negative 5
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

Depth: 7/2 feet
Rate: 5/4 feet per hour
Time = depth / rate of filling
Time = 7/2 / 5/4
Time = 14/5
Time = 2 4/5 hours
