Real World Radical Formulas
This week’s assignment involved solving real work radicals. We were required to solve two problems on pages 605 and 606. While this assignment was not easy for me, I feel like I most definitely learned something new. The problems involve sailboat stability and speed. I will be looking for the capsize screening value and the sail power of the sailboat.

Page 605 Problem 103
Sailboat Stability. To be considered safe for ocean sailing, the capsize screening value C should be less than 2. For a boat with a beam (or width) b in feet and displacement d in pounds, C is determined by the function:

C = 4d-1/3 b
A)Find the capsize screening value.
Displacement = 23,245
Beam = 13.5
C = 4(23245)-1/3 (13.5)Values plugged into the formula.
C = 4(.035)(13.5)Applied exponent first.
C = 1.4(13.5)Multiplication left.
C = 18.9Capsize Screening Value.
B.) Solve for D.
C = 4d-1/3 b
4d-1/3 b = cFlipping equation so d is on the left.
4d-13 b = cDivide both sides by 4b.
4b 4b

(d-1/3)3 = c3Raise all sides to the 3rd power.
4b

D = c3 Formula solved for D.

Page 606 Problem 104
Sailboat Speed. The sail area-displacement ratio S provides a measure of the sail power available to drive a boat. For a boat with a displacement of d pounds and a sail area of A square feet S is determined by the function:

A.)S = 16Ad-2/3
Sail Area = 810 Square Feet
Displacement = 23245
S = 16(810)(23245)-2/3Values plugged into formula.
S = 16(810)(.00122776)Exponent applied first.
S = 12960(.00122776)Multiplication left.
S = 15.9Formula solved for sail power.
B.)Write d in terms of A and S.
S = 16Ad-2/3
16Ad-2/3 = SMoved d to the left of the equation.
16Ad-2/3 = SDivide both sides by 16A
16A 16A

QUADRATIC FUNCTIONS

Quadratic functions are perhaps the best example of how math concepts can be combined into
a single problem. To solve these, rules for order of operations, solving equations, exponents, and
radicals must be used. Because multiple variables are involved and affect the outcome,
quadratics are extension of functions as well. I am to solve problem numbers 56 on page 666-667
(Dugoplski, 2012).
Maximum profit. A chain store manager has been told by the min office the daily profit, p, is
1
related to the number of clerks working that day. X, according to the function p= -25x^2 +300x.
We need to figure out the number of clerks that will maximize the profit, and what the profit
maximum possible profit will be.
Will this function produce a minimum or a maximize and why? How will the maximum
possible profit affect the company?
-25x^2 + 300=0
divide both sides by -1
dp/dx = -50x + 300 =0
factor the left side by -1
dp/dx = -0
at maximum or maximum is -50x + 300 =0, or x= 6.
I will solve each equation
d/dx (dp/dx) or (d^2)p/ (dx^2)
is < 0 for a maximum or 0 for a minimum. The parabola
will cross the x axis at 0 and 6, so (d^2)...

RealWorldRadicalFormulas (title required on first line)
Though radicals seem complicated at first glance, the concept simply extends what is
already known about exponents and the order of operations. Additionally, manipulating formulas
that include radicals is no different than those without, providing appropriate rules are followed.
These rules include accurately finding the cube and square root for numbers and understanding
the application of the solution in the realworld.
It is stated in #103 on page 605 (Dugopolski, 2012) that the capsize screening value C
should be less than 2 if a boat is to be considered safe for ocean sailing. The formula is given as
C = 4d-1/3b where d is the displacement in pounds and b is the beam width in feet. The exponent
of -1/3 means that the cube root of d will be taken and then the reciprocal of that number will be
used in the multiplication....

RealWorldRadicalFormulasRadicalformulas are used in the realworld in the fields such as finance, medicine, engineering, and physics to name a few. In the finance department they use it to find the interest, depreciation and compound interest. In medicine it can be used to calculate the Body Surface of an adult (BSA), in engineering it can be used to measure voltage. These formulas are vital and important not only in algebra but also as we can see in our day-to-day lives. This assignment requires that we find the capsizing screening value for the Tartan 4100, solve the formula for variable of d, and find the displacement in which the Tartan 4100 is safe for ocean sailing. The problem is broken down into three parts. The utilization of formulas will be used.
The problem and work will be on the left hand side and a description will be to the right of the work describing the steps taken to solve this assignment. The following words will be bold throughout the assignment to indicate that there is a clear understanding of their definition and use: radical, root, and variable. The...

...challenges and move into the world. This is shown by a personal battle with their inner self, personal choice leading to a change in their emotions, different people having different ways of adapting to new challenges, individuals trying to shut off the rest of the world and the help of others an individual's attitude will change as they enter the world. This is shown the the novel The story of Tom Brennan by J.C Burke and in the movie Shrek by (director)
An individual's personal battle with their inner self may hold them back as they try to overcome challenges and enter into the world. The author uses flashbacks throughout the novel from Tom's perspective. These are of the night of the accident and show the reader that Tom is affected by the actions of his brother on that night. It also shows that Tom is held back and has a hard time overcoming the challenges that he faces due to these memories. The use of dialogue between Tom and Chrissy is used when Tom opens up about why he doesn't like to visit Fin. This conversation shows the reader that he is finally opening up about his old life that has help him back for so long. By Tom talking about this with Chrissy he has changed his personal choice and decided he doesn't want to be held back by his old life anymore. Once a person gets control of their inner self then they overcome challenges that they face in their new life as they move into the...

...In her book, The RealWorld of Technology (1999), Ursula M. Franklin argues that technology has a disruptive effect on humanity. If left-unchecked technology will eventually destroy society as we know it. Franklin illustrates her point by focusing on the effects technology has had on society and cultures in the past. She uses examples from China before the Common Era to the Roman Empire, with a majority of examples coming form the last one hundred and fifty years. Such as the Industrial Revolution and the invention of electronic mail. Franklin contends that for society’s sake, people must question everything before accepting new technologies into their world. In the book, Franklin’s argument urges people to come together and participate in public reviews and discuss or question technological practices that lead to a world that is designed for technology and not for society. The RealWorld Of Technology attempts to show how society is affected by every new invention that comes onto the market and supposedly makes life more easy going and hassle free while making work more productive and profitable. The lectures argue that “technology has built the house in which we live” (Franklin, p.1) and that this house is continually changing and being renovated. There is very little human activity outside of the house, and all in habitants are affected by the...

...office as independent India's first Prime Minister, and re-elected when the Congress Party won India's first general election in 1952. As one of the founders of the Non-aligned Movement, he was also an important figure in the international politics of the post-war era. He is frequently referred to as Pandit Nehru ("pandit" being a Sanskrit and Hindi honorific meaning "scholar" or "teacher") and, specifically in India, as Panditji (with "-ji" being a honorific suffix).
The son of a wealthy Indian barrister and politician, Motilal Nehru, Nehru became a leader of the left wing of the Indian National Congress when still fairly young. Rising to become Congress President, under the mentorship of Mahatma Gandhi, Nehru was a charismatic and radical leader, advocating complete independence from the British Empire. In the long struggle for Indian independence, in which he was a key player, Nehru was eventually recognized as Gandhi's political heir. Throughout his life, Nehru was also an advocate for Fabian socialism and the public sector as the means by which long-standing challenges of economic development could be addressed by poorer nations.
PERSONAL LIFE AND EDUCATION
Jawaharlal Nehru was born to Motilal Nehru (1861–1931) and Swaroop Rani (1863–1954) in a Kashmiri Pandit family. Nehru was educated in India and Britain. In England, he attended the independent boy's school, Harrow and Trinity College, Cambridge. During his time in Britain, Nehru was also...

...Realworld situation – Dell Inc.
Dell Inc. was founded in 1984 by Michael S. Dell, who developed the supply chain formula, which would end up making Dell one of the world leaders in PC sales. When applying the resource-based view and the VRIN-framework to Dell, it becomes clear that Dell has a definite competitive advantage. Dell’s success-formula combines several resources which are “unique, valuable to customers, and difficult to imitate”.
What makes Dell so special, is the fact that it does not use a middleman. The firm sells directly to its customers, which means that it has significant cost savings. Even in the 1990s, when Dell was just becoming successful, the operating costs were only 18 percent. This was roughly a half of the operating costs of its competitors. Dell still has a competitive advantage caused by cost leadership, which in turn is the result of experience. One reason for these low costs was mentioned earlier, the lack of a middleman, which in this case would be the retail stores. As a result, the products sold by Dell are often cheaper than its substitutes found in stores, because the latter include the retailer’s extra expenditures. Dell can afford to charge cheaper prices because of its second cost saving advantage: the fact that its inventory costs are minimal. Since customers tell Dell exactly what kind of product they want, Dell does not have to guess what the demand will...
