Write the equation x^2+y^2-2x-4y-11=0 in standard form.

Write the general form equation of (x+10)^2+(y+5)=16

The letters x and y represent rectangular coordinates. Write the following equation using polar coordinates (r, θ). xy=1 possible solutions: 2rsinθcosθ=1 r²sinθcosθ=1 rsin2θ=2 r²sin2θ=2 I chose: r²sinθcosθ=1 Am I wrong?

The letters r and θ represent polar coordinates. Write the following equation using rectangular coordinates (x, y). Given equation r=5

The letters x and y represent rectangular coordinates. Write the following equation using polar coordinates (r, θ). Given equation: y=x I chose: r=cosθ

The letters r and θ represent polar coordinates. Write the following equation using rectangular coordinates (x, y). r=1+sinθ I chose: x²+y²=√(x²+y²+y) (I am not completely sure about this)

Wait! It just appears (x-1)^2 + (y-2)^2=16 and (x-1)^2 + (y-2)^2=4 so it would be this one? I think its this one (x-1)^2 + (y-2)^2=16 what about you?

Could you explain to me how? I wasn't school when the class was given and I am struggling a bit with it
