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.
Answer:
14 ft
Step-by-step explanation:
Let x represent the number of segments of the divided wood beam
Let y represent the total length of the wood beam.
Given that each segment measures 3.5, the equation to express this scenario is given as
y = 3.5x
Thus, to find the length of the wood beam, substitute x = 4 into the equation.
We would have:
y = 3.5(4)
y = 14
Length of the wood beam = 14 ft
Is there only choices A and B?
From the choices I can see you don’t even have to do any work. The equation starts with (y =). This indicates you will be working with the y intercept. The y intercept is simply where the line crosses on the y axis. In this graph, the y intercept is 2.5. Out of your choices (A and B that I can see) only one contains + 2.5.
B is your answer UNLESS there are choices c and d that are cut out.
