Answer:
Step-by-step explanation:
Decrease = 58- 19 = 39

Uh, I assume you're talking about Percy Jackson. The answer would be the flying shoes, which Percy cannot use because flying would mean entering Zeus's territory, and Percy and Zeus are not getting along. I hope this helps!
Answer:
it's A
Step-by-step explanation:
you start at 2, then subtract 4, and get -2, which is what you end with.
Polar coordinates (r,ϑ) and Cartesian coordinates (x,y) are related as follows:
Cartesian -> Polar
x = r cos(ϑ)
y = r sin(ϑ)
Polar -> Cartesian
r^2 = x^2 + y^2
ϑ = arctan( y/x)
The polar coo's can be extended to cylindrical by introduction a dimension z - which is perpendicular to the polar plane, it follows that:
z = z
in between the systems (r,ϑ,z) and (x,y,z)
The polar coordinates are particularly useful when a problem has circular or cylindrical symmetry, i.e. it is usually "easier" to perform calculations on a circle (for example) using the polar coordinates.
