Answer:

he total time is 4 seconds. The elevator descends 10 feet each second so the total is:

 

4seconds x -10 feet/sec = -40 feet

 

The total change in elevation is -40 feet. You need the negative sign because the elevator is moving downward. Hope this helps!

<h3>Answer:  9.4 feet</h3>

Work Shown:

sin(angle) = opposite/hypotenuse

sin(22) = x/25

x = 25*sin(22)

x = 9.3651648353978

x = 9.4

Your calculator needs to be in degree mode. One way to check is to compute sin(30) and you should get 0.5 or 1/2.
