Answer:
Function is decreasing on (-8,infinity)
Step-by-step explanation:
The given function is
The first derivative is given by
For the function to be decreasing, we have
Divide both sides by -2. Since, we are dividing by a negative number hence, the inequality sign will change.
Subtract 8 to both sides
Therefore, the function is decreasing on (-8,infinity)
First option is correct.
Answer:
The intensity of an earthquake with a magnitude of 2 is 100 times greater than the intensity of a standard earthquake.
Explanation:
The magnitude of earthquakes is given by
Where I is the intensity of earthquake and S is the intensity of standard earthquake.
The magnitude of standard earthquakes is given by
So comparing the magnitude of the given earthquake and standard earthquake,
which means that
times greater
Therefore, the intensity of an earthquake with a magnitude of 2 is 100 times greater than the intensity of a standard earthquake.
