I might not be right but a is 2 and b is 16
Step-by-step explanation:
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:

Answer:
x=11
Step-by-step explanation:
first you flip the X and the 10, then subtract the 10 on both sides and you should be left with x=11
Answer:
