Given the equation of an hyperbola in the form:

Then the focus of the hyperbola is

Compute like this:

So the two focus points are

The vertices are given by the formula:

We deduce the two vertices of the given hyperbola:

since
The area of a square is: A = s^2
With side being s = 20m
A = 20^2m^2 = 400m^2
Hope that helps! :)

Answer:
4 consecutive odd numbers are 111, 113, 115 and 117.
Step-by-step explanation:
Let the first odd number be x.
So the next odd number will be (x+2)
and the next two consecutive odd numbers are (x+ 4) and (x+6)
According to question,
The sum of all four odd consecutive numbers = 456
⇒ x + (x+ 2) + (x+4) + (x+6) = 456
or, 4x + 12 = 456
⇒ 4x = 456 - 12 = 444
⇒ x = 444/4 = 111
Hence, the first odd number = 111
Second odd number = 111+ 2 = 113
Third odd number is x + 4 = 111 + 4 = 115
And last odd number is x + 6 = 111 + 6 = 117
So, 4 consecutive odd numbers are 111, 113, 115 and 117.
84,996 of the registered voters voted. If 157,400 is 100 percent of the registered voters then you can take 54 percent of 157,400 (157,400 * 54) which equals 84,996
