27+19 can be re-written as : 19+27
Now we can add them.
19
+27
-------
46
Our final answer: 46
Answer:

Step-by-step explanation:
First, let’s check to see if the direction vector is a unit vector:

It’s not a unit vector. therefore let's divide the vector by its magnitude in order to convert it into a unit vector:

Now, the directional derivative is given by:

So let's calculate the partial derivates:



Therefore:

Step-by-step explanation:
180°= 3q+q+q (Sum of angles in a triangle)
180°=5q
q=180÷5
q=36
Acute angle=36°
Obtuse angle=108°
-2.5(1-2n)-1.5n
=-2.5+5n-1.5n
=-2.5+3.5n
Answer: B. -2.5+3.5n
I believe this is the correct answer Y= 3/2x+2
Hope this helped you and have a fantastic day!
