Answer:
Loss section
Step-by-step explanation:
Given
-- cost
-- revenue
Required
Determine where n = 150 is
To do this, we substitute 150 for n in the given functions





The above shows that the revenue is greater than cost for n = 150.
This implies that, n = 15o is the loss section.
Answer:
<h2>90°</h2>
Step-by-step explanation:
First you must calculate the module or the magnitude of both vectors
The module of u is:

The module of v is:

Now we calculate the scalar product between both vectors

Finally we know that the scalar product of two vectors is equal to:

Where
is the angle between the vectors u and v. Now we solve the equation for 

the answer is 90°
Whenever the scalar product of two vectors is equals to zero it means that the angle between them is 90 °
The answer I believe is -1/9
