Answer:
The question has some details missing. Here is the given function ; f(x,y,z) = 1 + 4xyz at point P = (1,-1,-1)
Step-by-step explanation:
The detailed steps and appropriate calculation is as shown in the attached file.
The rest of the question is as following
What is the distance from person B to the top of the hill?
===================================================
Answer;
The attached figure represents the explanation of the problem.
So, it is required to find the distance BH
It will be calculated as following
∠A = 65° and ∠B = 80°
∴ ∠H = 180° - (65° + 80° ) = 35°
But the side AB = 45
So, we can use the sine rule to find the side BH
∴ BH ≈ 71.1 feet
∴ The distance from person B to the top of the hill ≈ 71.1 feet
