Body mass index Essay Example for Free

Body mass index EssayIn this assignment I pull up stakes demonstrate every step of the process of determining my bodymass index or BMI. After finding the body mass index I will then complete the followingintervals based on my height. The formula used to determine the body massindex is BMI= 703W , where W represents a soulfulness weight in pounds and H represents a personH2height in inches.My height is 70 inches. The first interval shows a compound contrast for17BMI2217703W22H2To contrive it an equivalent inequality I replaced the BMI with the formula17703W22702 My height in inches replaced H217703W224900then multiply by the height that was shape17(4900)703W22(4900)4900cancelling is performed83300703W107800 multiplication carried out83300703W107800703 703 703to get W by itself all terms were divided by 703118.49W153.34After completing the problem I determined that people who are 70 inches may have a longer that average life if they weigh between 118.49 and 153.34To solve this in terval Im sacking to solve for W prior to solving the inequality.23703W25H2 cypher by H223H2703W25H2 Divide by 703 to get W by itself23H2703W25H2703703703 it is now an equivalent inequality23(4900)W25(4900)703 703from solving the first interval I know that my squared height is 4900. I then plugged it in the place of H2 then multiplied112700W122500703 703160.31W174 DivideA person of 70 inches who weighs between 160.31 and 172 is probably not overweight.The third interval indicates a range for a person that is probably overweight. I understand thisproblem by inputting the number into the last compound inequality for 23 25.25BMI29.925(4900)W29.9(4900) cover703 703122500W146510703 703 Divide174.25W208.41A person that is 70 inches tall probably is overweight if their weight is between 174.25 and 208.41.The last interval is to be solved for someone who is obese. The inequality isBMI30 Since this is not a compound inequality I only need to use the middle and right terms.W30(4900) Multi ply703W147000 Divide703W209.10This interval indicates a person of 70 inches in height is obese if their weight is greater than or equal to 209.10.Of the 4 regions Im going to notate interval 4 which states a person is obese if theirweight is greater than or equal to 209.10.X is going to represent those who are obeseX= (209.10, )Graphed it would start at 209.10 pounds and so to infinity or it would never end. ( 209.10 In conclusion, during the course of the week I versed two different ways to solve for inequalities. I found that by solving for W in the intervals 2 through 4 was a pot easier and quicker than completing all the steps in the first interval.ReferenceDugopolski, M. (2012).
