Answer:
The answer to your question is: 12
Step-by-step explanation:
You have a function with two conditions,
- the first condition do not consider number nine, because it uses the symbol <, then we can not evaluate nine in this function.
- the second condition considers nine because uses the symbol ≤ which means that nine is considered here, but the function equals 12, so that is the solution.

x=-5
x=-5/2
x=-10

Answer:
Step-by-step explanation:
We have the conversion from polar coordinates to cartesian as
x =rcost and y = rsint where (r,t) are the polar coordinates
Also all trignometric functions are periodic with period = 2pi
Using this we find out

Thus we converted polar to rectangular coordinates.
Reverse would be
from (x,y) to (r,t) as
