Our overall goal in this problem is to find the location of a point b that lies on the line between points A and C.
What do know from what's given?
Location of point A
Location of point C
The relative distance of point B along the segment/line AC (given as a ratio of 3:1)
Now that we have listed everything we know, lets figure out what we can calculate based on this information:
Since we have both the locations of points A and C, lets calculate the length of this segment. For this we can think of this edge as the hypotenuse of a right triangle that is formed from the height (which is the distance between the x-coordinates) and the base (which is the distance between the y-coordinates).
We'll need two equations here:
Distance:
Calculate the distances for the height and the base of this triangle formed from the segment AC (the hypotenuse of the right triangle)
a (base) = |x2 - x1| ... where A (x1,y1) and C (x2,y2)
b (height) = |y2 - y1| ... where A (x1,y1) and C (x2,y2)
Note: Absolute value is used here since distance is always positive
Pythagorean Theorem:
Once we know the distance of the base and the height, we'll be able to calculate the segment (aka the hypotenuse of this formed triangle)
c2 = a2 + b2
After we calculate the distances for a and b, we can then solve for c, giving us the length of segment AC. Great! We're halfway there - next is to figure out how far point B is from points A and C, using the distance along the segment AC.
Recall the third piece of information we were given: the relative distance of point T along segment AC. How can we represent this information in an equation using the distance of segment AC?
The ratio to which point T splits the segment AC is given as 3:1 - this means that one part is 3 times as long as the other part. The natural question to ask here is "3 times as long as what?" This 'what' piece is what we want to find out - lets call it x.
Another important observation to make is that this ratio is describing two parts of a whole segment - so if we think of this is two pieces of a whole, we can think of it as '3 times something' and '1 times something' is equivalent to the entire segment.
So, using this terminology with x, lets rewrite what we said in words into an equation:
3x + 1x = c (Length of AC)
Solving for x, we see that x = [tex]\frac{C}{4}[/tex]
Now that we have the distance from point D to point T, and from Point T to point F, we can take up the final step of determining the location of T.
Lets imagine the entire segment ABC as the hypotenuse of a triangle again. This time we want to imagine (feel free to draw this yourself as well) a like straight down from T, perpendicular to the base of this right triangle.
What we have now is a small right triangle (with segment DT as the hypotenuse) within a larger right triangle (with segment DF as the hypotenuse). What this means is that we have two proportional triangles.
With this information, we can create a proportion statement that says:
(AT) Hypotenuse small Triangle / Height smallTriangle ~ (AC) Hypotenuse large Triangle / (b) Height large Triangle
Recall that we had solved for b in the beginning as the y distance between points D and F. This means the only variable missing is Height small Triangle, which results to be:
Height small Triangle = (AT) Hypotenuse small Triangle × (b) Height large Triangle / (DF) Hypotenuse large Triangle
Adding Height small Triangle to the y coordinate of point F gives us point T's y coordinate.
Now that we have the hypotenuse length and the height length of the small triangle formed by AT (as the hypotenuse) we can plug in those numbers into the Pythagorean theorem to since for there final missing side: the base:
Base small Triangle 2 = (AT) Hypotenuse small Triangle 2 Height small Triangle 2
Finally, we add Base small Triangle to the x coordinate of point B gives us point T's x coordinate.

Sedimentary rocks can tell us about the past environment of the Earth's surface. Because of this, they are the main narrators of past climate, life, and major events on the surface of the Earth. Each type of environment has specific processes that cause specific types of sediment to accumulate there.
Sedimentary rocks are perhaps the most comprehensive in Earth's history, as they record the features of remote mountain ranges, sediment-carrying river systems, and ultimate environmental features where sediments accumulated and solidified.

Currents cause warmer and cooler temperatures in the areas where they are located. please select the best answer from the choices provided t f
True. The currents, turning are they warm or cold, are a very big factor in defining the temperatures of the seaside regions where they have big influence. If the currents are warmer, it also suggests that they are wet as well, so they are creating the temperatures on the coastlines much more durable, higher, and there's much smaller divergence between the day and night temperatures.
Why are currents warm or cold?Differences in moisture density, resulting from the variability of water temperature (thermo) and saltiness (haline), also cause ocean currents. This method is known as thermohaline circulation. ln cold regions, such as the North Atlantic Ocean, ocean water fails heat to the ambiance and becomes cold and dense.

Why does relative humididy not give an accurate indication of the actual amount of water vapor in the air?
Relative humidity does not give an accurate indication of the actual amount of water vapor in the air because it is temperature dependent and it is inversely proportional to air temperature.
Relative humidity is the amount of water vapor in the air compared to the maximum amount possible at the current temperature. Relative humidity also measures water vapor, but relative to the temperature of the air. In other words, it is a measure of the actual amount of water vapor in the air compared to the total amount of vapor that can exist in the air at its current temperature.

How does stable air differ from unstable air? What weather conditions would lead you to believe that air is unstable?
Stable air differ from Unstable air and the weather conditions would lead you to believe that air is unstable
When compared to unstable air, stable air is more resistant to upward motion. When stable air is made to rise, it often forms thin clouds that only sometimes provide light to moderate precipitation. On the other hand, when unstable air rises, clouds are frequently towering and heavy precipitation is possible.
When the air in a mass of air is warmer and/or more humid than the air above it, the air is said to be unstable in the lowest levels of the mass. The air will rise as a result because the air parcel is warmer than the air around it at that time. The weather can shift abruptly and become violent in an unstable setting.

What do you notice about the location of the plate boundaries and the location of the earthquakes?

Assuming 10-percent trophic efficiency, the other 90 percent of the energy associated with a given trophic level is transferred to higher tropic levels.

There is less and less energy for each nutrient level, going up the pyramid. The amount of energy corresponds to the amount of biomass. Nutritional efficiency is the efficiency by which mass (or energy) is transferred from one trophic level to the next through predation.
Personal efficiency is the efficiency with which a typical individual turns consumption into somatic growth.

Air would simply flow directly from high-pressure areas to low-pressure regions if the Coriolis effect didn't exist.
Almost all sciences that study the motions of the Earth and other planets need to understand the Coriolis effect. The dynamics of the atmosphere, including the movements of winds and storms, depend on it. It aids in explaining the motions of oceanic currents in oceanography.

Because lenses act like a prism to separate the colours of the spectrum, they produce a troublesome effect known as Chromatic abberation.
Chromatic aberration (CA), also known as chromatic distortion and spherochromatism in optics, is when a lens fails to bring all colours into focus at the same location. It results from dispersion because the lens elements' refractive indices change depending on the light's wavelength.
Most transparent materials lose refractive index as wavelength increases. Because a lens's refractive index determines its focal length, variations in that index have an impact on focusing.
