Question

The Burj Khalifa, the tallest building in the world with 163 floors, is having problems with its air conditoning system. It is suspected that the difference in the air pressure between the first floor and the top floor is the problem. Normal atmospheric pressure for the bottom floor is 14.7 psi. A building engineer uses the function, P, to analyzw pressure. P(f) represents the pressure on each floor, where f is the floor number. Which of the following would be the possible domain?
A. {1, 2, 3, ....}
B. {1, 2, 3, .....,163}
C. {14.7, 14.6, 14.5,...,0}
D. {14.7, 14.6, 14.5,...}

Answer 1

This question was already asked so I will put the answer here.

The correct answer is letter (B) {1,2,3,4,...,163}.The burj khalifa the tallest building in the world with 163 floors, is having problems with is air conditioning system. It is suspected that thedifference is air pressure between the first floor and the top floor is the problem. normal pressure for the bottom floor is 14.7psi. a building engineer uses the function p to analyse pressure p(f) represents the pressure on each floor, where f is the floor number.

Answer 2

Answer:

Option B. { 1, 2, 3,......, 163 }

Step-by-step explanation:

The Burj Khalifa, the tallest building in the world with 163 floors, is having problems with its air conditioning system.

Normal atmospheric pressure for the bottom floor is 14.7 psi. Building engineer uses the function, P, to analyze the pressure P(f) where f is the number of the floor.

It means in function P(f), f is the variable at x axis and pressure P on y-axis.

As we know domain of a function is the values of x-variables. So possible domain will be 1, 2, 3,........., 163.

Option B. { 1, 2, 3,......, 163 }
