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
Answer:
Step-by-step explanation:
12 yd : 20 yd
both has yd on both sides, this means 12:20 = 12/20
12/20 simplified: 3/5
sub 2 for any "x"
3(2)^2-2(2)+1
6^2-4+1 i dont know if you need to simplify even more but if you do
36-4+1 32+1 31
i hope this helps you!
Subtract 4 from 15 to get 11.
=x+11
