Answer:
E(-2, -1.5)
Explanation:
From the diagram attached, the coordinates of point C and D are at C(1, 6) and D(-3,-4)
If a line segment AB with coordinates at
is divided by a point O(x, y) in the ratio n:m, the coordinates of point O is given by the formula:

C(1, 6) and D(-3,-4) are divided three fourths (in ratio 3:1) by point E. Let us assume E is at (x,y), hence the coordinate of point L is given as:

Point E is at (-2, -1.5)
Answer: thermosphere is the layer of the earth's atmosphere directly above the mesosphere and directly below the exosphere while mesosphere is layer of the earth's atmosphere that is directly above the stratosphere and directly below the thermosphere.
Answer:

Explanation:
The length of LM is twice as the length of QR and the length of MN is twice as the length of RS. By Pythagorean theorem, the length of LN is twice as the length of QS. Then,
.
