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)

Why do scientists think earth's core contains iron?

fgiga [73]

The overall specific gravity of the earth is much higher than the specific gravity of crustal rocks which means the earth is about twice as heavy as the rocks on the surface would suggest. Iron meteorites are thought to have the same composition as the average earth, and the meteorites contain a lot more iron than the Earth's surface rocks.
