The tallest building in the world is the Burj Khalifa tower in Dubai in the United Arab Emirates2. The elevator within the tower descends at a rate of 33 feet per second.3

Suppose you get on the elevator at the observation deck. After
10 seconds, you look at the display and see that you are now
1,490 feet above ground. Use the point-slope formula to find the linear equation for this situation. Let H(t) represent the height of the elevator above the ground t seconds after the elevator begins to descend.

Sagot :

The linear equation to calculate the height is H(t)=33t.

Given that the elevator descends at the speed of 33 feet/second.

If a person gets on the elevator at the observer deck and after 10 seconds he finds himself at 1490 feet above the ground then height descended  in 10 seconds= 33×10

                                         = 330 feet

The height of the observer deck from the ground = 1490+330

                                                                             = 1820 feet

The required equation to calculate the height of above the ground H(t)=33t.

We can calculate  the height of the elevator at any instant using the above expression.
