Find the values of e, a, b, and c for r = 24/(4 + 2sin theta)

Step-by-step explanation:

r=24/(4+2sin θ)

4r+2r sin θ=24

divide by 2

2r+r sin θ=12

2√(x²+y²)+y=12

2√(x²+y²)=12-y

squaring

4(x²+y²)=144-24y+y²

4x²+3y²+24y=144

4x²+3(y²+8y+16-16)=144

4x²+3(y+4)²-48=144

4x²+3(y+4)²=144+48

4x²+3(y+4)²=192

divide by 192

which is an ellipse with centre(0,-4) major axis on y-axis.

the amount you'd have after the work is $1.55

step-by-step explanation:

you subtract 95% from $31.

answer: the common difference is -0.10
