Answer & Explanation:

C) They used modern technology to improve prevention programs and screen travelers.

They quickly contained Ebola in a little span of 3 years. The plague lasted from December 26th, 2013 to June 9, 2016. In 2016 all cases were confirmed to be taken care of, as the majority had herd immunity. There were only 11,323 lost ones during this time period. This may sound like a lot, but, so far in our outbreak, which has lasted from December 2019 to the current time, May 19, 2021. It's not even fully cured and we're sitting on a 587,000+ count with over 33 million cases! It's been less time than the Ebola and we've managed to rise numbers in this thing. However, with the help of technology, we can find vaccines for these diseases and help people to stay safe as well.

Remember, stay safe! This vaccine is out! Make sure to get yours as soon as you possibly can, and if you don't, still stay safe! Wear your mask or just keep your distance from those you don't know. Do simple things like coughing or sneezing into your elbow or into a tissue, it helps to keep your loved ones, yourself, and the people around you safe.

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

3. The transatlantic slave system had tremendous effects on the peoples of the Americas, Europe, and Africa.

Develop an argument that evaluates the extent to which the transatlantic slave system affected culture during the period from ca. 1450 to 1750 CE.

Explanation:

In Africa, the slave trade had disastrous consequences. Rebel groups and tribal groups who benefited financially from the slave trade created an environment of anarchy and brutality. Throughout much of west Asia, population reduction and a persistent fear of imprisonment caused severe economic growth nearly impossible.

Women during the pregnancy period and men who would usually be starting families made up a significant number of those kidnapped in Africa. People who were old, disabled, or otherwise completely reliant who may have been less able to participate to their communities' health of the economy were often left behind by European slave owners.

Many people, businesses, and countries benefited greatly from the atlantic slave trade. However the brutal human trafficking and huge amount of deaths that resulted ultimately ignited well structured resistance to the trade.The slavery was abolished by the British in 1807. Imprisoned citizens in Former colonies were liberated by another legislation enacted in 1833.

In 1808 Congress passed a law prohibiting the spread of slavery into the U. S. Though the law passed it not end slavery completely.  Other nations, including Spain, Netherlands, Sweden, and France, had enacted legislation prohibiting the expansion of slavery by the 1820s.

However, since there was still a large market for enslaved people and money to be made from trading in them, such legislation did not necessarily put an end to slavery. The atlantic abolition of slavery was eventually abolished in the late 1800s thanks to new legislation and continuing protection measures.

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

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.

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.

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.

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].

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.
