<h3>HOPE IT HELPS!!!!!!</h3>
We have been given an equation of hyperbola 
. We are asked to find the center of hyperbola.
We know that standard equation of a vertical hyperbola is in form 
, where point (h,k) represents center of hyperbola.
Upon comparing our given equation with standard vertical hyperbola, we can see that the value of h is 6.
To find the value of k, we need to rewrite our equation as:
Now we can see that value of k is 
. Therefore, the vertex of given hyperbola will be at point 
and option D is the correct choice.
Every whole number<span> is a </span>rational number: for example, 3=31. ... Everywhole number<span> n can be written as a fraction of integers: n=n1. We aren't required to write it that way; we just need to know that it is possible to express every </span>whole number<span> as a fraction of integers, and hence it is </span>rational<span>.
So I Believe the Correct Answer would Be D)</span><span> If a number is not a rational number, then it is not a whole number. The converse is true</span>
Answer:
Part A
71°
Part B
The ladder is been used safely
Step-by-step explanation:
Part A
We solve the above question using Trigonometric function of Cosine
cos x = Adjacent/Hypotenuse
Adjacent = The distance between the house and the bottom of the ladder = 4 feet
Hypotenuse = Length of the ladder = 12 feet
x = Angle
Hence:
cos x = 4/12
cos x = 1/3
x = arc cos (1/3)
x = 70.528779366°
Approximately to the nearest degree
= 71°
Part B
According to the manufacturer, if the angle the ladder forms with the ground, x, is between 70° and 75°, then it meets safety standards. Is this ladder being used safely?
Angle x = 71°
Therefore, the ladder is been used safely
