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
Answer:
y = -2x+4
Step-by-step explanation:
the equation of the line there is: y = -2x+8
The parallel line to this one should have the same slope as the first one(-2x)
Parallel lines always have the same slopes
To find the zeros set the factors on the numerator equal to zero and solve
(x - 1) = 0 x = 1
(x + 1) = 0 x = -1
Answer:
Yes
Step-by-step explanation:
Each input must only have one output. In other words, an x-value goes with one y-value. in this model, each input has an output.
