What are the x- and y-coordinates of point c, which partitions the directed line segment from a to b into the ratio 5: 8? round to the nearest tenth, if necessary.

x = (startfraction m over m + n endfraction) (x 2 minus x 1) + x 1

y = (startfraction m over m + n endfraction) (y 2 minus y 1) + y 1

true. earthquakes are felt whenever there is a slip around a fault in the rocks below the earth. this reorientation of faults create sesmic waves and is known as earthquake, the severity of which is measured in richter scale. these are more prominent in hilly regions as the rocks usually form faults to balance the pressures on it.
