Leased Lines In this paper we will answer the following questions a-g for a better understanding of leased lines.
a. Below what speed are there different leased line standards in different parts of the world?
Lease lines span between 1.544 Mbits/second for a typical T1 located in North America to over 34 Mbits/second in Europe. It was below 50 Mbits of data transmission when difficulties started to occur from country to country so that different parts of the world could configure their own set of lease line standards (Panko & Panko 2011). b. What is the exact speed of a T1 line?
North America provides lease line access in the form of T1. This is a dedicated connection which supports data rates of 1.544 Mbps (Panko & Panko, 2011). c. What are the speeds of comparable leased lines in Europe?
The comparable lease line standards start at the speed of 2.048 Mbps which is known as E1. Europe provides a similar structure to the North American for data connectivity. Even though Europe’s’ structure may be similar to North American structure it is different. d. Why are fractional T1 and E1 speeds desirable?
Fractional T1 and E1 speeds are desirable because they help to alleviate cost. They also provide dedicated transmissions that can be divided into different lines for multiplexing data and voice communications. The T1/E1 is mainly used by companies and individuals that have a demand on internet access performance that is going to be dependable. e. List common fractional T1 speeds.

Difficulties start below 50 Mbits of data so different countries have different lease line standards. b. What is the exact speed of a T1 line? A T1 line is a lease line in North America. This connection is a dedicated connection that can support up to 1.544 Mbps based on a digital signal on 24 channels at 64 Kbps. c. What are the speeds of comparable leased lines in Europe? The comparable lease lines in Europe to a T1 in North America can support up to 2.048 Mbps. The network structure is similar yet still different from the network setup of North America. d. Why are fractional T1 and E1 speeds desirable? Fractional T1 and E1 speeds have a large effect on costs, efficiency and use. The use of these dedicated lines is dependable and consistent and mainly used by companies and/or individuals who require a dependable access to the internet. e. List common fractional T1 speeds. Fractional T1 speeds include 128 kbps, 256 kbps, 384 kbps, 512 kbps, 768 kbps. f. What are the most widely used leased lines?

...1a. Answer: (1.0, 228,000), (2.0, 216,000) 1a. Key work steps 1b. Answer: $-12,000 1b. Key work steps Since M= y2-y1/x2-x1 then M= 216,000-228,000/2.0-1.0 M=-12,000/2.0-1.0 M=-12,000/1.0 M=-12,000 1c. Answer: Y= (-12,000)*x+240,000 1c. Key work steps Since Y=mx+b then and do figure m we use the formula m= (y2-y1)/(x2-x1) I know now what m is in my equation in this situation it’s -12,000 and to figure b is just the Y intercept which in this case is 240,000. So I get my linear equation Y= (-12,000)*x+240,000. 1d. Answer: $126.000 1d. Key work steps Now if this depreciation were to continue until 2019 then we use our formula to determine the value of the plane. Y=(-12,000)*x+240,000 now x is the number of years from the end of our graphing years which was half way through 2009. So in this case x will = 9.5 years now to plug this in. Y=(-12,000)*9.5+240,000 Y=114,000+240,000 Y= $126,000 2a. Answer: L=w-5 2a. Key work steps 2b. Answer: Width= 22.5 inches, Length is 17.5 inches 2b. Key work steps Since p=2L+2W and our equation L=W-5 then P=2(W-5)+2W P=2W-10+2W P=4W-10 We know that in this case P=80 inches so 80=4W-10 80+10=4W-10+10 90=4W 90/4=4W/4 22.5=W and since we know L= W-5 then L= (22.5)-5 L= 17.5 3a. Answer: C= $225+$10(x-2), C=(25x) 3a. Key work steps 3b. Answer:16.3 inches is needed 3b. Key work steps Our inequality for this problem is...

...before examining the actual context, it is also important to look at the form of the poem, which also plays a puissant role. First of all, and most noticeable, is the continual use of dashes, which adds a lingering essence, as if foreshadowing the death. The dashes also signify power and unanswered questions about death and, perhaps, whether or not an afterlife exists. Another aspect of the form is how it is broken up into stanzas expressing differing ideas in each one. By braking up such ideas, it is easier to analyze the varying aspects of death that Ms. Dickinson believes are imperative when expressing what she is feeling prior to her death. The first stanza starts off repeating the title, “I heard a Fly buzz—when I died—“ (line 1). These words, though odd, are explained through the rest of the stanza, as the insignificance of the sound of a fly’s buzz is magnified, thus becoming extreme, compared to “The Stillness in the room” (2). This “Stillness” is then related to the “Stillness in the air” (3). Though the “Stillness” causes the buzzing sound to take strength, “Stillness”, in this stanza, takes on a double meaning, which is representative of death as well. The second stanza differs from the first in that, as she lies in her bed, observers, who express their own emotions while witnessing her final moments, surround her. “The Eyes...

Airborne

...Airborne Jumping out of an airplane is a life experience one will never forget. People have different reasons for doing it. Some people skydive for the sport of it. It is an exhilarating and adrenaline pumping experience. I jumped out of an airplane to earn my airborne wings in the army. It all started in Airborne School, during ground week, where we were taught how to land safely and dawn a parachute. During tower week, the second week of training, we learned pre-jump preparations and how to properly exit an airplane. Finally, the third week of training came: jump week. My classmates and I made five jumps from a C130 aircraft. Two of the jumps were with just a parachute, known as Hollywood jumps. Two of the jumps were with full combat loads. One of the combat jumps had to be at night so that we could earn our jump wings. I woke up at “zero dark thirty”; a phrase that means before dawn in the army. I rolled out of bed sore from the two weeks of five mile runs every morning in full uniform and boots. My legs hurt from jumping from platforms and throwing myself to the ground learning to land correctly. I stood in formation, half asleep, while the airborne instructors briefed us for the events of the day. The airborne instructors are called Black Hats because of the black baseball caps that they wear with their rank and wings pinned to the front. That morning, our class had to jog three miles to the air field to get our Jump Master brief. I felt a slight chill in my bones...

Introduction to Linear Inequalities

... Instructor Charlie Williams May 9, 2013 Introduction On Linear Inequalities Linear equations are special kinds of algebraic expressions that contains two variables.  The value of one variable is dependent upon the other. The functions of inequalities are expressed as a line.  The complexity of linear equations and linear equalities are sometimes compared concerning the complications of each. Unlike linear equations, linear inequalities incorporate the assessment of where to shade after a solution has been determined.  Typically, two equations collaborate to compose a linear inequality. A linear equation will be made up of a combination of constants, a set of numbers and variables. The variables must be to the first power and cannot be squared or cubed. According to Michael Judge, the most common type of linear equation is in the form y = mx + b and describes a straight line (2010). In this case, the two variables are usually x and y and the constants are m and b which are numbers giving the slope and intercept of the line. Operations of Linear Equations Two equations and two variables are needed to find specific values.  My variables are: c = # of classic maple rockers m = # modern rockers A classic maple requires 15 board feet of maple, and a total of 15c maple for all classic maple rockers. A modern rocker requires 12 board feet of maple, and a total of 12m for all modern...
