The directional derivative of f at A in the direction of the vector AB is 9 and the directional derivative at A in the direction of
AC is 2. Find the directional derivative of f at A in the direction of the vector AD.
(Round your answer to two decimal places.)
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.

The number 31 is a prime number and has exactly one factor pair which is 1 and the number itself, so the correct answer is option B.
The value 31 is considered a prime number.
A prime number is a number that only two distinct positive divisors: 1 and itself. Therefore, every prime number has exactly one factor pair, which is 1 and the number itself.
So, option B-31 is a prime because it has 1 factor pair is the correct answer. This means that the factors of 31 are simply 1 and 31.
so the correct answer is option B.

If the value of the variable x is negative 3 then the value of the even function is 3. Then the correct option is C.
Even Function - A true function f(x) is said to be an even function if the output value of f(-x) is the same as the f(x) for all values of x in the domain of f.
The equation should be stored in an even function:
f(-x) = f(x)
The function is given below.
f(x) = f(3) = 3
Let the function f(x) be an even function. Then we have
f(-3) = f(3) = 3
