Answer:
0 is a rational, whole, integer and real number. Some definitions include it as a natural number and some don't (starting at 1 instead).
Answer:
x²+(y-5)²=25
Step-by-step explanation:
To convert polar into rectagular
also, y=rsin θ => sin θ=y/r
r= 10sinθ
r= => r²=10y
therefore, x²+y²-10y=0
By completing the squares on y²-10y gives
x²+(y-5)²=25
which is the equation of the circle.
This is the Cartesian equation of a circle with center (
0,
5)
and radius, r=5
