How to convert rectangular to polar?
x²=y(8-y)

The Polar form  is  r = 8sin θ

Step-by-step explanation:

Explanation:-

Polar co-ordinates

              x = r cos θ    and      

               y=r sin θ      

now      

               tan θ =

Now given equation x²=y(8-y)

                                    ...(i)

now The equation(i)  convert to polar

                                      r² = 8(r sin θ)

                                      r = 8sin θ

Conclusion:-

The Polar form is  r = 8sin θ

answer: the 4 kilogram bag

step-by-step explanation: this is because if you divide the number of kilograms into the total it will tell you how much each individual kilogram would be worth. 2 kilos is 7 and change 3 would be around 6 ish and the 4 kilo would be 4.6 and change and the 5 kilos would be like 4.88
