Answer:
y=-2x+4
Step-by-step explanation:
It is two easy to take away 5
To find the area of the composite figure, first find the area of the rectangle.
14 * 5 = 70
Then find the area of the circle

I can not see the dimension of the radius so just put the radius in the equation.
Then half the area of the circle for the semicircle.
Answer:
Step-by-step explanation:
put x=r cos θ
y=r sin θ
r²cos²θ-r²sin²θ=3rsin θ
r²(cos²θ -sin²θ)=3r sin θ
r²cos 2θ=3rsinθ
r cos 2θ=3 sin θ
r=3sec 2θ sin θ
