X= 5/mod I think this is the answer
Answer:
Step-by-step explanation:
The given notation is not clear enough, but I will asume that the question is: "Wich is the vector lenght of the vector in a 3 dimensional euclidean space"
Vector lenght of a vector is given by the next formula:
║║=
In this case we have a=2, b=3 and c=1. We should substitute these values in the formula given before to obtain:
║║=
Wich is the answer to the problem.
A. p = 8n - 30
Each item n is $8.
Expenses totaling $30 are subtracted.
So if the profit (p) is $170.00,
170 = 8n - 30
Now you need to solve.
Add 30 to both sides.
200 = 8n
Divide both sides by 8.
25 = n
25 items were bought.
b. If 25 items were bought, but the expenses were instead $40, what would be the total profit?
p = 8(25) - 40
p = 200 - 40
p = 160
The profit decreased by 10.
