Answer:
1/5
Step-by-step explanation:
Assuming the total number of all the trick or treaters that came to my house is N and the numbers of trick or treaters were dressed as characters from Star Wars is n.
Given that the portion of trick or treaters were dressed as characters from Star Wars, = 1/3 of all the trick or treaters.
Now, 3/5 of those dressed as characters from Star Wars were dressed as the character Darth Vader, so
The number of visitors that were dressed as the character Darth Vader
[ by using equation (i)]
Hence, the fraction of all trick or treaters were dressed as Star Wars and were Darth Vader is 1/5.

Answer:
x = - 4
Step-by-step explanation:
Given
y =
The denominator of y cannot be zero as this would make y undefined.
Equating the denominator to zero and solving gives the value that x cannot be and if the numerator is non zero for this value then it is a vertical asymptote.
x + 4 = 0 ⇒ x = - 4
Thus the vertical asymptote is x = - 4
To find the vertex of our parabola, we are going to use the vertex formula: For a quadratic of the form 
it vertex 
is given by 
, 
.
We can infet from our parabola that
and 
. So lets replace those values in our formula:
The vertex of our parabola is 
Now to find our second point, we are going to evaluate our parabola at
Our second point is
We can conclude that we can graph the parabola
using its vertex and the point as follows:
We can infet from our parabola that
The vertex
Now to find our second point, we are going to evaluate our parabola at
Our second point is
We can conclude that we can graph the parabola
