Essays on X-axis

The sine is the ratio of the opposite leg of the right triangle to its hypotenuse. Let’s imagine that we have the Cartesian coordinate system and a circumference with the same center and radius R. Every angle can be depicted as a rotation operation from the positive x-axis to some interval that joins together the center of the Cartesian coordinate system and some point of the circumference. The length of this interval is equal to the radius and can be depicted as the hypotenuse of the right triangle. The adjacent leg of the triangle belongs to the x-axis, ...

I and my friend James wanted to find out the absorption capacity of different color pigments mixed in water, when exposed to the infra-red radiation. Our hypothesis was the dark color pigment, on being subjected to infra-red radiation, would absorb more energy and will show up in the form of difference in temperature obtained before and after the exposure. Our experiment was influenced by some of the experiences in daily life. First observation was the preference of the light color clothes in hot day, as the light color reflects the sunlight and absorbs the little, preventing the body from ...

Among all great artists, M.C. Escher is the one who comes to mind when one thinks of mathematics. As I researched deeper into his art, I found out that he is more than just flirting with mathematics but in a marital relationship. So much that he can be referred to as a secret mathematician. Escher’s fascinating work holds inside a great knowledge of Euclidean and Non-Euclidean ...

Writing Assignment

In this project we are given with a graph of continuous function f which is defined on [0, 10]. Also, given that:

We have to answer on the number of questions regarding function g properties based on the information given about function f.

We begin with determination what is g(0)? Since g(x) is:

gx=0xftdt

Hence

g0=00ftdt≡0

It’s zero, because the integral’s limits are equal.

Consider g10: g10=010ftdt The function value at this point is an integral from f(x) among its domain – from 0 to 10. As we know, the geometric interpretation of the integral is the area of under the graph of the function. That’s why if we consider the areas under the graph above ...

1.0 Dependence of Relative Permeability on Petrophysical Properties

Carbon dioxide (CO2) entering the atmosphere from sources such as power plants, oil exploratory and production sites and traffic pollution from fossil fuel-burning vehicles. CO2 exists in high concentrations in the atmosphere which increases the impact of the greenhouse gas phenomena which makes the global warming problem worse. The relative permeability of soils is linked to finding a solution for removing large concentrations of CO2 by sequestering CO2 in appropriate geological formations. Data from a study by Bennion and Bachu (2005) is available online at the Relative Permeability Explorer. The Explorer is ...

Question #1

a) Break-even analysis is important to assess the current state of the enterprise and its dynamics, as well as for the development strategy of the company. For the definition of concepts such as break-even point and financial headroom is necessary, first of all, to define the fixed and variable costs. These concepts are used in the solution of almost all kinds of administrative tasks in the system "costs - production volume - profit."

Fixed costs do not depend on the quantity produced.

Example: The company leases land. For this land has to pay a rent of $ 100. This cost is formed regardless of the ...

IMPLICIT ASSOCIATION TEST FOR RACE

Abstract The Implicit Association Test (IAT) measures human attitudes. Implicit attitudes are considered those judgments or actions of people that are automatic and the person has no idea what causes that judgment or action. The automatic action is a result of influences from societal beliefs. IAT is different from qualitative psychological tests for measuring attitudes because the measurement is of the cognitive processes of memory that cause a person to show a particular attitude automatically. IAT-Race was used to study racial stereotypes in an experiment to determine if the “Obama Effect” was observed. The participants were prompted to go to a web ...
