The unit vector is given by the following formula:
a '= (a) / (lal)
Where,
a: vector a
lal: Vector module a
We are looking for the module:
lal = root ((- 15) ^ 2 + (8) ^ 2)
lal = 17
Same direction:
a = -15i + 8j
The unit vector is:
a '= (1/17) * (- 15i + 8j)
Opposite direction:
a = 15i - 8j
The unit vector is:
a '= (1/17) * (15i - 8j)
Answer:
a unit vector that has the same direction as the vector a is:
a '= (1/17) * (- 15i + 8j)
a unit vector that has the opposite direction of the vector a is:
a '= (1/17) * (15i - 8j)

Given situation : 0.5 pound of peaches selling for 0.80 dollars/ pound
0.7 pound of oranges selling for 0.90 dollars / pound.
Solution
Given number 1 : Peaches
=> 0.5 pound = meaning, ½ pound is available, And 1 pound of it costs 0.80 dollars.
Let’s solve:
=> 0.80 dollars * 0.5
=> 0.40 dollars – the price of the peaches.
Given number 2 : Oranges
=> 0.7 pounds of oranges, meaning less than 1 pound. And 1 pound costs 0.90 dollars
Let’s solve to get the anwer
=> 0.7 * .90
=> 0.63 dollars – the costs of 0.7 pounds of oranges,
