Which technique combines two-dimensional Images Into a three-dimensional Image?
The _______________
technique combines two-dimensional images and enhances them to create a three-dimensional image. This technique is used by forensic scientists to recreate crime scenes and evidence.
Answer:
Originally, stereogram referred to a pair of stereo images that could be viewed using a stereoscope. Most stereoscopic methods present two offset images separately to the left and right eye of the viewer. These two-dimensional images are then combined in the brain to give the perception of 3D depth.
Explanation:
The stereoscopic technique combines two-dimensional images and enhances them to create a three-dimensional image. This technique is used by forensic scientists to recreate crime scenes and evidence.
The general technique used by forensic scientists for the creation of 3-D image illusion with 2-D images is stereogram.
What is the use of three-dimensional images over 2-D images?The 2-D images are flat with the presence of the two geometrical axis, which made the development of the simple images with one perspective only. While the 3-D images are given with the presence of the third dimension as well, which adds multiple perspectives to the images for analysis.
The technique of stereogram is used for the development of three-dimensional illusion with the use of two-dimensional flat images. These are generally used by scientists for the recreation of crime scenes and evidence.

Explanation:
The function of a protein molecule depends on its____
and how it interacts with other_____
Answer:
Structure; protein molecules.
Explanation:
In Biology, blood pH can be defined as a measure of the hydrogen ion (H¯) concentration of blood i.e the level of alkalinity or acidity of blood.
Basically, the normal blood pH of a human being should be between 7.35 and 7.45.
Hence, one of the ways in which the body regulates blood pH is with proteins. Proteins help regulate blood pH by accepting and releasing hydrogen ions. Typically, when the blood pH falls, the hydrogen ions (H¯) are accepted (absorbed) while hydrogen ions are released when the blood pH rises.
For example, a protein such as haemoglobin which makes up a composition of the red blood cells, binds an amount of acid required to regulate blood pH.
The structural formula or dimension of a protein and its relationship (interaction) with other protein molecules generally determine the function of a protein.
Simply stated, the function of a protein is largely dependent on its structure and the level of interaction with other protein molecules.

Answer:
What is human development?
In 1990 the first Human Development Report introduced a new approach for advancing human wellbeing. Human development – or the human development approach - is about expanding the richness of human life, rather than simply the richness of the economy in which human beings live. It is an approach that is focused on people and their opportunities and choices.
People: human development focuses on improving the lives people lead rather than assuming that economic growth will lead, automatically, to greater wellbeing for all. Income growth is seen as a means to development, rather than an end in itself.
Opportunities: human development is about giving people more freedom to live lives they value. In effect this means developing people’s abilities and giving them a chance to use them. For example, educating a girl would build her skills, but it is of little use if she is denied access to jobs, or does not have the right skills for the local labour market. Three foundations for human development are to live a long, healthy and creative life, to be knowledgeable, and to have access to resources needed for a decent standard of living. Many other things are important too, especially in helping to create the right conditions for human development, and some of these are in the table below. Once the basics of human development are achieved, they open up opportunities for progress in other aspects of life.
Choice: human development is, fundamentally, about more choice. It is about providing people with opportunities, not insisting that they make use of them. No one can guarantee human happiness, and the choices people make are their own concern. The process of development – human development - should at least create an environment for people, individually and collectively, to develop to their full potential and to have a reasonable chance of leading productive and creative lives that they value.
As the international community moves toward implementing and monitoring the 2030 agenda, the human development approach remains useful to articulating the objectives of development and improving people’s well-being by ensuring an equitable, sustainable and stable planet.
The Human Development Index (HDI) is a summary measure of average achievement in key dimensions of human development: a long and healthy life, being knowledgeable, and have a decent standard of living. The HDI uses the logarithm of income, to reflect the diminishing importance of income with increasing GNI.
The HDI was created to emphasize that people and their capabilities should be the ultimate criteria for assessing the development of a country, not economic growth alone. The HDI can also be used to question national policy choices, asking how two countries with the same level of GNI per capita can end up with different human development outcomes. These contrasts can stimulate debate about government policy priorities.
The Human Development Index (HDI) is a summary measure of average achievement in key dimensions of human development: a long and healthy life, being knowledgeable, and have a decent standard of living. The HDI is the geometric mean of normalized indices for each of the three dimensions.
The health dimension is assessed by life expectancy at birth, the education dimension is measured by the mean of years of schooling for adults aged 25 years and more and expected years of schooling for children of school entering age. The standard of living dimension is measured by gross national income per capita. The HDI uses the logarithm of income, to reflect the diminishing importance of income with increasing GNI. The scores for the three HDI dimension indices are then aggregated into a composite index using a geometric mean. Refer to Technical notes for more details.
The HDI simplifies and captures only part of what human development entails. It does not reflect on inequalities, poverty, human security, empowerment, etc. The HDRO offers the other composite indices as a broader proxy on some of the key issues of human development, inequality, gender disparity, and poverty.

Explanation:
A rectangular tent has a perimeter of 24 feet. Its area is 32 square feet. What are the dimensions of the tent?
Answer:
4 feet by 8 feet
Explanation:
Given
[tex]P =24[/tex] -- Perimeter
[tex]A = 32[/tex] --- Area
Required
The dimension of the tent
The perimeter of a rectangle is:
[tex]P =2(L + W)[/tex]
Where
[tex]L = Length\\ W = Width[/tex]
So, we have:
[tex]2(L+W) = 24[/tex]
Divide both sides by 2
[tex]L + W = 12[/tex]
Make L the subject
[tex]L = 12 - W[/tex]
The area is calculated as:
[tex]A = L* W[/tex]
This gives:
[tex]L * W = 32[/tex]
Substitute[tex]L = 12 - W[/tex]
[tex](12 - W) * W = 32\\[/tex]
Open bracket
[tex]12W - W^2 = 32[/tex]
Express as quadratic equation
[tex]W^2 - 12W - 32 = 0[/tex]
Expand
[tex]W^2 - 8W -4W- 32 = 0[/tex]
Factorize
[tex]W(W - 8) -4(W- 8) = 0[/tex]
Factor out W - 8
[tex](W - 4)(W- 8) = 0[/tex]
Split
[tex]W - 4 = 0\ or\ W - 8 = 0[/tex]
Solve for W
[tex]W =4\ or\ W = 8[/tex]
Recall that:
[tex]L = 12 - W[/tex]
Substitute [tex]W =4\ or\ W = 8[/tex]
[tex]L = 12 - 4 = 8[/tex]
[tex]L = 12 - 8 = 4[/tex]
So, we have:
[tex]W =4\ or\ W = 8[/tex]
[tex]L = 8\ or\ L = 4[/tex]
So, the dimension is: 4 feet by 8 feet
What is the arc length of the central angle is 225 degrees and the radius of the circle is 6 meters?
Answer:
Length of arc = 23.57 meter (Approx.)
Explanation:
Given:
Radius of given circle = 6 meter
Central angle = 225°
Find:
Length of arc
Computation:
Length of arc = [θ/360][2πr]
Length of arc = [225/360][2(22/7)(6)]
Length of arc = [0.625][12(3.1428)]
Length of arc = [0.625][12(3.1428)]
Length of arc = [0.625][37.7136]
Length of arc = 23.571
Length of arc = 23.57 meter (Approx.)

Martina, a sophomore, plans to backpack in Europe for a month after she graduates from high school. What is this an example of?
A. A short-term goal
B. A long-term goal
C. A priority goal
D. An enabling goal
Answer:
Option A, This is example of short term goals
Explanation:
A short-term goal is planned for future (today, a week, a month, or a year). Such goals need small time period to complete the task and hence are short goals while the task that take long time for completion are long term goal. Option B is incorrect as backpacking in Europe will not take long. It is also not a priority goal as a priority goal remains same and continues for a long time. hence, option C is incorrect
Option D is incorrect because it is not an enabling goal as it is not at all helping to achieve a long term goal
Hence, only option A is correct
An object of mass m is moving in a straight line with velocity v and is slowing down from a force F = -kv where k is a constant. At time t = 0, the velocity is [tex]v_{0}[/tex]. How can I derive an equation for the object's velocity as a function of t?
Answer:
The equation of the object's velocity in time is [tex]v(t) = v_{o}\cdot e^{-\frac{k\cdot t}{m} }[/tex].
Explanation:
By Newton's Laws of Motion, the equation of motion that represents the deceleration of the object is described by:
[tex]\Sigma F = - k\cdot v = m\cdot \frac{dv}{dt}[/tex] (1)
Where:
[tex]k[/tex] - Damping constant, in newton-second per meter.
[tex]m[/tex] - Mass, in kilograms.
[tex]v[/tex] - Velocity, in meters per second.
[tex]\frac{dv}{dt}[/tex] - Acceleration, in meters per square second.
Then, we modify (1) until the following ordinary differential equation with separable variables is found:
[tex]-\frac{k}{m} \int \, dt = \int {\frac{dv}{v} }[/tex] (2)
Then, we integrate the equation and find the following solution:
[tex]-\frac{k}{m}\cdot (t-0) = \ln \frac{v}{v_{o}}[/tex]
[tex]- \frac{k\cdot t}{m} = \ln \frac{v}{v_{o}}[/tex]
Finally, we clear the velocity in the solution of the differential equation is:
[tex]v(t) = v_{o}\cdot e^{-\frac{k\cdot t}{m} }[/tex]
The equation of the object's velocity in time is [tex]v(t) = v_{o}\cdot e^{-\frac{k\cdot t}{m} }[/tex].
Explain how the rise of secondary sector employment affects population size in urban communities.
Answer:
The rise of secondary sector employment affects population size in urban communities by attracting more people to migrate into the area causing the population to also rise.
Explanation:
I was looking for the answer to so instead I answered it.
The rise of secondary sector employment leads to rise in the population in urban areas as it will have more people moving there.
Why the migration above?There are a lot of incoming technology such as the use of machines in agriculture and it has been found that a lot of farmers and workers often look for jobs in the the secondary sector and thus leading to urban migration.
Conclusively, Note that this will lead to a rise in the population in urban centers as more people go there and there will be a rise of secondary sector employment.

Answer:
#
P(R I Q) = P(RnQ) / P(Q) = 0.1 Therefore P(RnQ) = 0.1 X 0.35 = 0.035 (The intersection in the centre of a Venn Diagram)
P(RnQ') = 0.15 In a Venn Diagram this is R but excluding the centre intersection with Q. Therefore P(R) = P(RnQ') + P(RnQ) = 0.15 + 0.035 = 0.185
P(RUQ) = 0.15 + 0.035 + 0.315 = 0.5 so 0.5 must be outside the Venn Diagram circles.
