Nt1310 Unit 2 Formulas

FORMULAS All four of these formulas use the following terms: inequality, equivalent, and interval. Formula numbers one, two, and three use the term compound inequality. Formula number four uses the term infinity. In these formulas I am going to figure out the weight amounts, better known as (w). Formulas are definitely something that I have had to re-teach myself. They are not super complicated; but, at first glance, it is definitely confusing. Formulas are definitely not as complicated once they are broke down into a better understanding.
#1. 17 < 703w/4,225 < 22 My height to the second power will be plugged in to (H) as the
amount of 4,225. 17*4225 < 703w < 22*4225 I will take 4,225 and set it up to multiply times 17 and 22.
71,825 < 703w < 92,950 Multiplied. 71,825/703 < 703w/703 < 92,950/703 Now, I will take all three components and divide by 703. 703w/703 will cancel out 703 and leave the (w). Answer: 102.03 < w < 132.22 People that weigh between 102.03 and 132.22 with the height of five foot even might have a longer life span than
average.
Graph: <--------(--------------------------------)----------> 102.03 132.22

#2.
23 < 703w/4,225 < 25 My height to the second power will be plugged in to (H) as the amount of 4,225. 23*4,225 < 703w < 25*4,225 Set up 4,225 to be multiplied by 23 and 25. 97,175 < 703w < 105,625 Multiplied. 97,175/703 < 703w/703 < 105,625/703 Now set up to divide all three components by
703. 703w/703 will cancel out 703 and leave the (w). Answer: 138.23 < 150.25 People that weigh between 138.23 and 150.25 with the height of five foot even will probably not be overweight.
Graph: <-------(-------------)------> 138.23 150.25

#3. 25 < 703w/4,225 < 29.9 25*4,225 < 703w < 29.9*4,225 105,625 < 703w < 126,327.5 105,625/703 < 703w/703 < 126,327.5/703 Answer: 150.25 < w < 179.70 People that weight between 150.25 and 179.70 with the height of five foot even will probably be overweight.
Graph: <---------(-----------------------------)------> 150.25 179.70

#4. 703w/4,225 > 30 703w > 30*4,225 703w > 126,750 703w/703 > 126,750/703 Answer: w > 180.30 People with the weight of 180.30 and above with the height of five foot even will be obese.
Graph: <--------(-------------------------------------> 180.30 to infinity.

CONCLUSION All of these expressions qualify under the category of inequalities. Formula number one is a compound inequality, in which intervals are being plugged into the appropriate places to evaluate the expression properly. Number two is also a compound inequality in which intervals are being plugged into the appropriate places just the same. Number three is a compound inequality as well in which intervals are being plugged correctly too. Number four is not considered a compound inequality but it has an infinity possibility. Formulas are definitely something that I have had to re-teach myself. They are not super complicated; but, at first glance, it is definitely confusing. Formulas are definitely not as complicated once they are broke down into a better understanding.
