Answer:
Option D. 2.51 is correct.
Step-by-step explanation:
Magnitude of first earthquake = 8.6
Let intensity of first earthquake be x

Magnitude of second earthquake = 8.2
Let intensity of second earthquake be y

Now, to find the factor by which intensity of first earthquake is greater than intensity of second : we divide equation (1) by equation (2)

Hence the required factor is 2.51
Therefore, Option D. 2.51 is correct.
Answer:

Step-by-step explanation:
1. rewrite the equation in standard form: 
2. find (h,k), the vertex. the vertex is 
3. find the 'focal length' of the parabola - the focal length is the distance between the vertex and the focus. from the vertex we can see that the focal length, p, = 3/2
4. Parabola is symmetric around the y-axis and so the asymptote is a line parallel to the x-axis, a distance p from the
y coordinate which is at
. Set up the equation:

5. substitute and solve:


hope this helps, ask me questions if you still don't understand.
-55 is an i
nteger.
It is not a whole number because it is negative.
It is not a natural number because it is not a whole number.
It is not irrational because it can be written as a fraction

Oh okay
Brainliest would really help :))
