Answer:
The directional derivative of f at A in the direction of
AD is 7.
Step-by-step explanation:
Step 1:
Directional of a function f in direction of the unit vector
is denoted by
,
.
Now the given points are
,
Step 2:
The vectors are given as
AB = (10-8, 9-9),the direction is
AC=(8-8,10-9), the direction is

AC=(11-8,13-9), the direction is

Step 3:
The given directional derivative of f at A
is 9,

The given directional derivative of f at A
is 2,

The given directional derivative of f at A
is



The directional derivative of f at A in the direction of
is 7.

4. v=-4
Answer:
y=2/3x-4
Step-by-step explanation:
we can see that x goes up 1 for every 1.5y and if we start y at 0 x starts at -4 so if y is one than x has to be 2/3-4 becuase it is -4 + 2/3 for every 1 y goes up or one for every 1.5 y goes up. hope this answer was helpful.
