Given directed line segment KM , find the coordinates of L such that the ratio
poizon [28]

Answer:

The answer is below

Explanation:

The question is not complete, the coordinates of K and M are not given. Let us assume The coordinates are at K(1, -6) and M(9,-2)  

Answer: If a line segment AB with coordinates at (x_1,y_1)\ and\ (x_2,y_2) is divided by a point O(x, y) in the ratio n:m, the coordinates of point O is given by the formula:

x=\frac{n}{n+m}(x_2-x_1)+x_1 \\\\y=\frac{n}{n+m}(y_2-y_1)+y_1

K(1, -6) and M(9,-2)  are divided in ratio 1:3 by point L. Let us assume L is at (x,y), hence the coordinate of point L is given as:

x=\frac{n}{n+m}(x_2-x_1)+x_1=\frac{1}{1+3}(9-1)+1=\frac{1}{4}(8)+1=3   \\\\y=\frac{n}{n+m}(y_2-y_1)+y_1=\frac{1}{1+3}(-2-(-6))+(-6)=\frac{1}{4} (4)-6=-5

Point L is at (3, -5)

The force that drives earthquake activity is _____. magnetic force kinetic energy potential energy plate tectonics
larisa86 [58]
<span>The correct answer is plate tectonics. The outermost shell of Earth, called the lithosphere, is partitioned into different tectonic plates (7 or 8 major ones). When a plate breaks along what are called faults, there is a release of energy, which causes seismic waves (the ground shaking). This shaking then causes several plates to rub against each other, and when they break, the earthquake results.</span>
