Answer: Choice 4) A to B to C to E to D to A to E to B
An Euler path is a path where you use each edge or road exactly one time. Think of it like crossing a bridge and when you cross the bridge, the rope is cut so you can't reuse the bridge again. If we started at A, went to B, then to C, then to E, then to D, then back to A, then to E again, then finally to B, we would use up all of the edges. I've provided a diagram of what's going on (see attached image below). The idea is to start at point A, follow the red arrows until you get back to point A, then follow the blue arrows until you get to point B. This is <u>not</u> a circuit because we started at point A and ended up at some other point that isn't point A (in this case, point B). We would need to end up at the same starting location to have a circuit.
Answer:
a. ![r=1+2\cos(\theta)](https://tex.z-dn.net/?f=r%3D1%2B2%5Ccos%28%5Ctheta%29)
Step-by-step explanation:
The curve
![r=1+2\cos(\theta)](https://tex.z-dn.net/?f=r%3D1%2B2%5Ccos%28%5Ctheta%29)
is not a conic.
Convert to rectangular coordinates.
First multiply through by r.
![r^2=r+2r\cos(\theta)](https://tex.z-dn.net/?f=r%5E2%3Dr%2B2r%5Ccos%28%5Ctheta%29)
Substitute ![r^2=x^2+y^2](https://tex.z-dn.net/?f=r%5E2%3Dx%5E2%2By%5E2)
and
![x=r\cos(\theta)](https://tex.z-dn.net/?f=x%3Dr%5Ccos%28%5Ctheta%29)
![x^2+y^2=\sqrt{x^2+y^2}+2x](https://tex.z-dn.net/?f=x%5E2%2By%5E2%3D%5Csqrt%7Bx%5E2%2By%5E2%7D%2B2x)
We can see clearly that this is not a conic.
is an equation of a cardioid.
is a circle.
is a parabola.
is an ellipse.
Answer:
#5 39 = x
Sides:
x - 15
2x
2x
Total of sides = 180
180 = (x-15) + 2x + 2x
180 = x - 15 + 4x
180 = -15 + 5x (add 15 to each side to remove -15)
195 = 5x (divide by 5 on each side to get x)
39 = x
#7 24 = x
Sides:
2x - 4
3x + 5
2x + 11
Total of sides = 180
180 = (2x - 4) + (3x + 5) + (2x + 11)
180 = 2x - 4 + 3x + 5 + 2x + 11
180 = 7x + 12 (subtract 12 to each side to remove 12)
168 = 7x (divide by 7 on each side to get x)
24 = x
#8 37 = x
Sides:
x
x + 4
3x - 9
Total of sides = 180
180 = (x) + (x + 4) + (3x - 9)
180 = x + x + 4 + 3x - 9
180 = 5x - 5 (add 5 to each side to remove -5)
185 = 5x (divide by 5 on each side to get x)
37 = x
