Answer:
The magnitude of the earthquake is 3.7 (approx)
Step-by-step explanation:
We know that the magnitude of an earthquake is,
Where, is the standard intensity of earthquake,
is the measured intensity of earthquake,
Here,
Hence, the magnitude of the earthquake is 3.7 (approx)
3.7
Which Expressions?
Since, x-coordinate is negative and y-coordinate is positive, point will lie in the 2nd quadrant.
Answer is point P.
(-3, 6)
Point L represents the given coordinates.
Point P represents the given coordinates.
Since, x and y coordinates are positive, point will lie in the 1st quadrant.
Point Q represents the given coordinates.
Since, both x and y coordinates are negative, point will lie in the 3rd coordinate.
Point R represents the given coordinates.
The lengths of the sides of the scalene triangle are 6, 11, and 12.
We want to use the law of cosines to find the largest angle.
Note that the largest angle is always opposite the largest side.
Therefore:
The largest angle is 84 degrees to the nearest angle.
