Answer:
The given expression
Step-by-step explanation:
Here, the given expression is: 
Now, starting from the outer most bracket.
As we know :

and 
⇒ 

Hence, the given expression
Ans: (c)
y = k/x^2
when y = 100, x = 1
100 = k/1^2
k = 100
when x = 2,
y = 100/2
= 50
(u/rachelmarrons already gave you the answer but here’s a step-by-step explanation in case you needed it haha)
The answer is 0.04
All you have to do is go to a calculator and type 4 then put %
The correct answer I believe you are looking for is D. Elevator 1 is 13 feet above ground level, and Elevator 2 is 10 feet below ground level.
<u>Explaination:</u>
This is because if you start at (0, 0) Elevator one, will go up 13 on the y axis. Putting it at 13 feet above ground level. If you start Elevator 2 at ground level on (0, 0) and go down 10 it will make it -10 AKA 10 feet below ground level.
I hope this helps! :)
