Given directed line segment CD, if point E divides CD three-fourths of the way
from C to D. find the coordinates of E. Round to the nearest tenth.
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 [tex](x_1,y_1)\ and\ (x_2,y_2)[/tex] is divided by a point O(x, y) in the ratio n:m, the coordinates of point O is given by the formula:
[tex]x=\frac{n}{n+m}(x_2-x_1)+x_1 \\\\y=\frac{n}{n+m}(y_2-y_1)+y_1[/tex]
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:
[tex]x=\frac{n}{n+m}(x_2-x_1)+x_1=\frac{3}{4}(-3-1)+1=\frac{3}{4}(-4)+1=-2 \\\\y=\frac{n}{n+m}(y_2-y_1)+y_1=\frac{3}{4}(-4-6)+6=\frac{3}{4} (-10)+6=-1.5[/tex]
Point E is at (-2, -1.5)

Apply: An archaeologist finds a golden figurine. How could she determine if the figurine is solid gold without cutting it?
Answer: By weighing it
Explanation:
The density of gold is known to be 19.3 g/cc and this was derived by dividing a particular mass of gold by its volume. As the density is already know, the archaeologist can then estimate the size of the figurine. Using the estimated size and the density, the archaeologist should be able to come up with a theoretical weight.
The archaeologist should then weigh the figurine. If the figurine's mass is quite different from the theoretical mass then it probable isn't solid gold.

Which of the following statements about time zones is true? A. Time zones are based on the days of the week. B. Time zones sometimes follow the borders of countries. C. Time zones’ boundaries are perfectly vertical lines (north to south). D. Time zones’ boundaries are perfectly horizontal lines (east to west). Please select the best answer from the choices provided
Answer:
(B) Time zones sometimes follow the borders of countries
Explanation:
Let's prove why each other statement is false.
A: Time zones are based on hours and they are determined through lines of latitude (15 degrees longitude each). So this is false.
C: Time zones boundaries are not perfectly vertical, as all boundaries in the US alone are not vertical, they follow a jagged line. This is also false.
D: Time zones are based on lines of latitude, meaning they run North-South, so they cant run East-West. This is false.
This leaves B.

Describe how volcanoes can form away from plate boundaries.
Answer:
Volcanoes are also common along tectonic boundaries where plates pull apart, allowing magma to rise from the mantle. ... Less commonly, a volcano can form over a hot spot far from a plate boundary. Heat carried by material rising from deep in the mantle melts some of the rock in the lithosphere above it.

The edge of a continent is found atthe boundary between low-densitycontinental rocks and higher-density oceanic rocks-The deepest parts of the oceans occur in elongate narrow trenches that areassociated withsubduction zones-Why do ocean water depths increase away from the midocean ridges?The accumulation of sediments over time adds weight to the sea floor. Older oceanic crust is denser and thus sits lower on the asthenosphere.-According to plate tectonic theory, the initiation of a rift zone is caused by the rise of hot mantle material toward the Earth's surface-Convection cells in the mantle form when hot mantle material rises, moves laterally, and then sinks when it becomes cold.Approximately 220 million years ago, the continents were joined together intoone supercontinent known as Pangaea. This super-continent was surroundedby an ocean named PanthalassaWhich of the following was the only process to occur during the last 65 millionyears?India rammed into Asia.The lateral spreading of the plates away from the elevated midoceanridge is driven in part bygravitational pullWhat led James Hutton to propose the the Earth must be extremely old?Henoted that natural processes, such as erosion, were very slow.

Explanation:
Which of the following is not one of the three types of physical processes that can cause weathering? A. biological B. cultural C. chemical D. physical
Answer:
Cultural
Explanation:
The physical properties that lead to weathering are the heat, the temperature, the pressure, frost, the root action, and the burrowing animal. Thus this process leads to an increase in the surface of the exposed area. and leads to a large number of disintegration.
Hence culture is not a type of physical weathering.As all the physical process includes physical and chemical activities it also includes the biological activities of the plants and animals, including man. The physical process leads to the disintegration that is the wear and tear of rocks.
Hence the above-mentioned process is associated with physical weathering except culture.
