Step-by-step explanation:
The distance between you and the elevator is given by:

The rate of change for the distance between you and the elevator is given by:



Applying the chain rule:

Therefore, at x=300 and y = 500, dy/dt is:

The elevator is descending at 18.66 ft/s.
Answer:
Step-by-step explanation:
10000*4%= 400 Geese year1
10400*4%=416 Geese year 2
10816*4%= 432.64 Geese year 3
11,248.64*4%= 449.95 Geese. year 4
11248.64+449.95= 11698.59
11698.59-10000=1698.59
Increased by 1699 Geese.
X-8+y^2=52 is the answer I believe
