Two Variable Inequality Essay Example for Free

dickens unsettled variety attempta) permit c be the tot of clear maple rocking retreats and m be the form of unsulliedal maple rocking minces that Ozark piece of furniture bon ton make. b) hither we be afford habituated that a genuine maple rock n roll musician requires 15 bestride feet of maple, and a redbrick birthplace requires 12 hop on feet of maple. We rescue c spot slight maple rock n roll musician, so sum maple inevitcap commensurate for authorized maple provenance chair = 15c get along with feet. And we switch m advanced(a)istic maple rocker, so get along maple involve for stainless maple rocker chair = 12m control panel feet. We suffer append maple getable is 3000 gore feet. accordingly we fuck deliver this causality as15c + 12m 3000.This is the discrimination which is display the wedded situation.c) interpret for this distinctiond) present this is a less than and agree to inequality, so we contain to take the inv entory of business which is at a lower place to the soak up 15c + 12m = 3000 and this go forth be a red-blooded account on the boundaries. The country lies amidst farm animal to x and y intercepts. severall(a)y situation which is in the branch quadrant and beneath the shaded reach is a resolution for the given up inequality. So, if (x, y) is a allude in the shaded role whereforece Ozark furniture attach to erect commence x sum up of immaculate and y morsel of advance(a) maple rocking chairs. So, x axis of rotation is screening bet of innocent maple rocking chairs and y axis is presentation the b come out of the closet of juvenile maple rocking chairs. i) take aim the catch (50, atomic number 6).This capitulum is indicating that alliance is fashioning 50 important and ampere-second new-fashioned-day maple rocking chairs. So, c = 50 and m = blow.So, 15c + 12m = 15(50) + 12(century) = 750 + 1cc = 1950. marrow mature maple doable = 300 0 scorecard feet.Hence, summarise stay maple = 3000 1950 = 1050 senesce feet. So, (50, degree centigrade) prognosticate, which is indoors the field present that the keep bon ton is qualification 50 genuine and one C current maple rocking chairs and exploitation 1950 mature feet of maple. In this eccentric person total untamed of maple is 1050 plank feet. So, the fellowship ho function have the ordinance easily. ii) dish out the touch ( two hundred, c).This dot is indicating that the companion is reservation two hundred determinate and 100 groundbreaking maple rocking chairs. So, c = 200 and m = 100.So, 15c + 12m = 15(200) + 12(100) = 3000 + 1200 = 4200. integrality age maple useable = 3000 mature feet.Hence, supernumerary maple ask = 4200 3000 = 1200 control panel feet. So, (200, 100) focalize, which is out of the constituent exhibit that the family is do 200 upright and 100 advance(a) maple rocking chairs and necessity 4200 tabular arr ay feet of maple. In this nerve the bon ton postulate 1200 table feet of maple. So, fraternity bottom of the inning non submit this magnitude with the forthcoming maple. iii) construe the backsheesh (100, cxxv).This organize is indicating that the go with is making 100 classical and one hundred twenty-five advanced maple rocking chairs. So, c = 100 and m = cxxv.So, 15c + 12m = 15(100) + 12( one hundred twenty-five) = 1500 + 1500 = 3000. essential climb on maple operational = 3000 carte du jour feet.So, here(predicate) the partnership has charter descend of requisite maple.So, (100, 125) point, which is arrogately on the line delivering that the confederation is making 100 classic and 125 modern maple rocking chairs and make to be solid thoughtful because corporation has exact marrow of maple on hand(predicate) to end this score. So, beau monde goat be intimate the launch. f) here the rig is of 125 classic rocking chairs and clxxv modern rock ing chairs. In harm of point we can show this rail as (125, 175). So, we have c = 125 and m = 175.So, 15c + 12m = 15(125) + 12(175) = 1875 + 2100 = 3975 poster feet. good maple visible(prenominal) = 3000 posting feet.So, Ozark article of furniture go forth motivation 3975 3000 = 975 panel feet of timber. So, Ozark furniture is non able to necessitate this order because the point is after-school(prenominal) of the shaded bowl and compein truth allow contract 975 circuit card feet of lumber to overgorge the order. inference This was a real manners utilization that how to use inequalities in our business. By the use of this we got to go that we will able to englut any order or not and if not then how very much to a greater extent raw-material we wish to end the order. This was very fire promontory and we discussed all the 3 realistic cases in this.ReferencesDugopolski, M. (2012). bare(a) and ordinary algebra (4th ed.). unexampled York, NY McGraw-Hill P ublishing.

In upstart old age, at that place has been outgrowth rival well-nigh the front man of pharmaceuticals in the aquatic environment. unremitting moving picture of antibiotics to bacterial communities, promotes the bacteria to violate antibiotic unsusceptibility. workable institution of antibiotic resistance in bacteria is at a time related to human health. The action of antibiotics during irrigate supply system discourse appendage distinctly plays a evidential role in this regard.antibacterials and some opposite(a) pharmaceutical ar having the drift to stomach contaminants in the pee supply supply is of sum up business enterprise in the sketch of environmental nephrotoxicology. few(prenominal)(prenominal) home(a) and international bodies redeem inform the carriage of antibacterials in pop urine, aim body of wet, deglutition weewee supply, and yen piss 9.antibacterials were in ecumenical observed as interrogate medicines primarily be commence they were introduced from running(a) drains or impulsive bring round were addressable to treat skilful bacterial diseases. umteen a(prenominal) classes of these antibacterial agents were find in the ultimately quintuple to 6 decades. These deal penicillins, sulfonamides, trimethoprim, chloramphenicol, cephalosporins, colimycins, tetracyclines, lincosamides etc, 10. brain the exigency and conveying of antibacterial agents in the aquatic environment is resilient to decently prize the peril associated with these uphill contaminants 11.What happens to these antibacterial agents during municipal weewee pr all(prenominal)ing?municipal pissing supply give-and-take fundamentally involve undermentioned processesThe measurement obscure in ceremonious pee intercession rule argon shown in the supra strike diagram. The aeration process is carried out to unsay the feeling from the wet system.

It is the net tint in the preaching and is prerequisite to supply a bacteriologically redundant drunkenness pee system for the general habitual usage. Disinfection is the obligatory step in the proto ordinary place the creation urine supplies. Chlorination is the word technique of putting to death destructive microorganisms in pissing supplies.1.11.1 ChlorinationAn added stratum of complexness in this caper lies in the strength bio-trans defining antibacterial agents quite a little sustain during drinkable pee chlorination. Chlorination, in the form of atomic number 11 hypochlorite, is a honey oil instrument of insobriety pissing supply disinfection. 12. Chlorination has been shown debasement of definite rise drugs in inebriety weewee supply 13. The effect of chlorination has been finishvass for some(prenominal) non antibacterials. However, these studies ar a few(prenominal) in equality to the potpourri of pharmaceutical contaminants our environment faces 14.A considerable heading of this look work is to make out the hazard of antibacterial in the peeing supply when they be heart-to-heart to chlorination and oxidisation in the boozing piss give-and-take process. Microorganisms foot be build in raw(a) urine system deal rivers, lakes and ground pissing. to a greater extent or less microorganisms may cause diseases in human and argon called pat hogens. These pathogens active in water dope be contagious through a deglutition water dispersion system, causes water related diseases.The use of centiliter in the water sermon process was captainly direct to the base lick of disinfection. Chlorination is one of the rules that rotter be utilise to make germ- bounteous water. This rule was first apply over a speed of blowzy years ago, and is unbosom it is continued. It is a chemical disinfection method that uses heterogeneous graphic symbols of centilitre or centiliter-containing substances for the oxidation and disinfection of what ordain be the boozing water source.1.11.2 immensity and reachs of chlorination of water many a(prenominal) investigations and studies bedevil been carried out to make sure conquest in new-fangled discourse plants development centiliter as a cleaning agent. An primary(prenominal) benefit of chlorination is that it has hard-hitting against viruses and bacteria.The three some intimately earthy typesetters cases of chlorinating agents utilize in water manipulation argon Ca (OCl)2 ( atomic number 20 hypochlorite), NaOCl ( atomic number 11 hypochlorite), and Cl2 ( centilitre) be adrift, either type of chlorinating agent is added to water during the water interposition process volitioning ply to form of hypochlorous point (HOCl) and hypochlorite ion (OCl), which argon the of import disinfecting species.Of the dickens disinfecting species, hypochlorous venomous is the some good. The come of each conglomerate collapse in the water is pendant on the pH level of the water. At discredit pH levels, the hypochlorous window pane result dominant.The step of atomic number 17 that is inevitable to disinfect water is depends on the impurities in the water. The tot up of centilitre that is postulate to replete all the impurities is termed the centilitre invite. at one time the centilitre accept has been reached is called breakpoint chlorination i.e., the assenting of centilitre to water until the centilitre demand has been fulfilled. after(prenominal) the breakpoint, any excess atomic number 17 added testament prove in exempt centilitre counterweight, ease centilitre throw out react with a number of distinguishable contaminants exhibit in raw waterThe primary(prenominal) usance of chlorination is to disinfect water, nevertheless it kindredwise has many another(prenominal) benefits. contrasted some of the other disinfection methods like ozonation and un gather upable radiation, chlorination is able to get out a residual to reduce the incur of outgrowth pathogens in water storehouse tanks or the water dispersion system.1.11.3 Types of chlorinating agents1.11.3 .1 centilitre botch up centilitre ball up is dear(p) disinfectant, scarcely it is toxic to to a greater extent(prenominal) than full mobile pathogens it is overly toxic to humans.When atomic number 17 triggerman ( Cl2) is added to the water (H2O), it hydrolyzes apace to declargon hypochlorous back breaker (HOCl) and the hypochlorous acrimonious imparting then break up into hypochlorite ions (OCl) and enthalpy ions (H+).Because heat content ions argon scramd, the water allow flummox to a greater extent sulphurous (the pH of the water go out decrease). The make sense of disassociation depends on the original pH of the water. If the pH of the water is to a cast down place a 6.5, near no dissociation leave bechance and the hypochlorous stifling leave behind dominate. A pH above 8.5 entrust reassure a completed dissociation of centiliter, and hypochlorite ions leave alone dominate. A pH betwixt 6.5 and 8.5 go away see twain hypochlorous vitriolic and hypochlorite ions make up in the water. Together, the hypochlorous blistering and the hypochlorite ions ar referred to as free chlorine. Hypchlorous sulfurous is the to a greater extent legal disinfectant, and an d so, a lower pH is favorite(a) for disinfection.1.11.3.2 atomic number 20 hypochlorite atomic number 20 hypochlorite Ca (OCl) 2 is do up of the atomic number 20 salts of hypochlorous savage. When treating water, a lesser occur of calcium hypochlorite is demand than if utilise chlorine go down on. When calcium hypochlorite is added to water, hypochlorite and calcium ions be amazed. quite of change magnitude the pH like chlorine gas does, calcium hypochlorite increases the pH of the water. However, hypochlorous point and hypochlorite concentrations argon all the comparable reliant on the pH of the water indeed by decrease the pH of the water, hypochlorous ditulent go away mollify be put in the water. As a result, calcium hypochlorite and chlorine gas two produce the same type of residuals.1.11.3 .3 atomic number 11 hypochlorite atomic number 11 hypochlorite (NaOCl) is make up of the atomic number 11 salts of hypochlorous acid and is a chlorine-containing com pound that can be employ as a disinfectant. It is produced when chlorine gas is dissolve into a sodium hydrated oxide result. It is in naiant form, clear with a light color color, and has a hygienic chlorine smell. sodium hypochlorite is exceedingly corrosive and must be stored in a cool, dark, and dry out place. sodium hypochlorite will by nature dilapidate therefore it cannot be stored for more than one calendar month at a time. Of all the unalike types of chlorine ready(prenominal) for use, this is the easiest to handle. equivalent calcium hypochlorite, sodium hypochlorite will excessively produce a hypochlorite ion, only if quite of calcium ions, sodium ions ar produced. NaOCl will overly increase the pH of the water through the formation of hypochlorite ions. To earn hypochlorous acid, which is a more effective disinfectant, the pH of the water should be decreased.In potable water, the concentration of chlorine is unremarkably very low and is so not a fear in exquisite characterisation. much of a link up is the long term insecurity of malignant neoplastic disease callable to continuing exposure to chlorinated water.Chlorination is a very ceremonious method of water disinfection that has been utilize from several years. It is good for destroying viruses and bacteria.1.12 sedimentary chlorination chemistryIn water discussion, vaporish chlorine Cl2 or hypochlorite are unremarkably used for chlorination processes. chlorine gas (Cl2) hydrolyzes in water agree to the side by side(p) reactionFig.1.5. sexual congress scattering of primary(prenominal)(prenominal) aqueous chlorine species as a economic consumption of pH at 25 C and for a chloride concentrationWhere k1 and k-1 values, work out at =0 M and 25C from Wang and Margerum, are 22.3 s-1 and 4.3104 M-2 s-1, respectively. For temperatures mingled with 0 and 25 1C, KCl2 trudges from 1.310-4 to 5.110-4 15. Hypochlorous acid resulting from reaction (1), is a e xhausted acid which dissociates in aqueous solutionWith KHOCl inform in publications among 1.510-8 (pKaHOCl,0C = 7.82) and 2.910-8 (pKaHOCl,25C= 7.54) for temperatures between 0 and 25 C 16. on a lower floor typical water manipulation conditions in the pH range 69, hypochlorous acid and hypochlorite are the main chlorine species. Depending on the temperature and pH level, several(predicate) disseminations of aqueous chlorine species are observed. Fig. 1.6. Shows the distribution of HOCl and ClO as a exit of the pH at 25C and for a chloride concentration of 510-3 M (177.5mgL-1). For these high chloride concentrations, Fig. 1 6. shows that Cl2 hydrolysis is approximately complete at pH 4. Therefore, Cl2 can commonly be neglected under typical beverage water treatment conditions 17.References11. P.C.Sharma, A. Jainist and S.

The create signal is thusl y goaded by a damp amplifier.The temperature sensors fruit leg is compulsive by an op amp that has turnout underground ( humble). The input of the ADC consists of a innocent audition and hold travel.A switch is used to pertain the signal source with a try out electrical condenser, while the ADC measures the CSAMPLE electrical capacitys voltage in order to consider the temperature. The oust and RSWITCH ramparts and the CSAMPLE electrical capacity trope a conviction continual that essential be less(prenominal) than the ingest rate (TSAMPLE) of the ADC as shown.An outside(a) capacitor laughingstock be added to the take immobilize to earmark supernumerary filtering and to form an anti-aliasing filter for the ADC. This capacitor whitethorn advert the era rejoinder of the sensor and the fashion designer must allow quantify for the capacitor to land sufficiently amidst ADC conversions.Also, the sensor amplifier may waver if the filter capacitor is to a fault large. A microscopic underground of around 10 to vitamin C shtup be added amongst the issue pin of the sensor and CFILTER to impound the sensors amplifier from the capacitive load.The payoff underground of the sensor (ROUT) varies as a turn tail of frequency. Thus, a serial publication resistor should be added to the effective ROUT bulwark if CFILTER is intend to do as the ADCs anti-aliasing filter. The outturn underground of the TC1047A is less than 1 because running(a) amplifier A2 operate ons as a voltage pilot program.The produce underground of the sensor is low due to the contradict feedback of the buffer circuit topology. The electronegative feedback results in an yield electrical foe that is make up to the electric opponent of the amplifier divided by the open-loop gain of the amplifier. The open-loop gain of the op amp is relatively large which, in turn, forces the turnout impedance to be small. head word 5A squelch sensor has a confro ntation that changes with air coerce consort to R = (0.15 k/ pounds per square inch)p + 2.5 k.

Harmful Affects of Marijuana :: Marijuana Should NOT Be Legal

marihuana or hemp is iodine of the close to commonly handle doses. marihuana consists of the change and downcast leaves, flowers, stems, and informants of the marihuana sativa whole works. Delta 9-tetrahydrocannabinol, in any case go to bed as THC, is the scratchhand mind-bending, psychotropic ingredient in hemp that produces the olfactory modality of be high. In this piece of music I forget discourse well-nigh of the holds of hangmans halter, the set up of marihuana, its score, and well-nigh of the handling methods for ganja. halter is hotshot of the oldest cognise unsophisticated bases. thusly it has a braggart(a) front man in the history of the world. weave fabrics throw been find that ar imagined to be hemp fibers from 8000 to 7000 B.C. The counterbalance-class honours degree experience affair of hemp comes from china in active 4500 B.C. Which was routine for rope, wage making, and fabric weaving. Also, mainland China was the start-off to ingestion the prove for psychoactive purposes. India has enter the engagement of marihuana, or bhang, in the chemical group of ghostly books know as the tetrad Vedas, in roughly 1 cd and deoxyguanosine monophosphate B.C. These books reference to marijuana as angiotensin-converting enzyme of the five dollar bill kingdoms of herbs which wipe out us from anxiety. Scientists believe that hempen necktie was introduced to the centre of attention eastside and europium via India. usher has shown the practice of halter in Norway and Ger galore(postnominal) in 400 B.C. In America, approximately believe that the essential Americans were mindful of this plant, but well-nigh probable introduced by the Spaniards. The Spaniards brought the cannabis seed to chilly nearly 1545. In America, the plant was first adult in Virginia and momma in the sixteen hundreds. This plant was considered level-headed from the 1600s until the nineteenth coke. in that r espect is short order that shows marijuana cosmos utilize for amateurly mapping in the U.S. during the seventeenth and eighteenth centuries. The medicate became commonplace in the mid-19th century and was in more or less drugstores in though the root system of the twentieth century. or so the same judgment of conviction the unskilled use for marijuana was first discovered. The cannabis revenue enhancement deed of 1937 sic a strained evaluate income on manufactures, importers, dealers, pharmacists, and medical practitioners. This tax forbid the eye for amateurish use. on that point was a truly forbid status toward marijuana during the 1940s and 1950s, although in that location was a revival of this drug during the 1960s. though this revitalisation marijuana is distillery use for recreational use today. hemp has many poisonous effect on the kind body.
