The teacher’s hypothesis is horribly inaccurate. First of all‚ Scenario A is the only linear function in the group consisting of A‚B‚ and C. Scenario B is a function‚ but not linear. Scenario C is not a function. Scenario A has all the criteria of a linear function. For every independent variable (aka “x” value or input) in the domain‚ there is one and only one dependent variable (aka output or “y” value) in the range. It can be written in the form “y=mx+b” where “m” and “b” are real numbers‚ “x”

Introduction Obesity can lead to various health problems. My school has decided to carry out a “Healthy Lifestyle Campaign” with the aim to create awareness among students about obesity-related health problems. The Body Mass Index (BMI) gives an indication of the physical state of person as being underweight‚ normal‚ overweight or obese. BMI can be calculated by using the following formula: BMI = History Body Mass Index (BMI) The body mass index (BMI)‚ or Quetelet index

GPS AND TRIANGULATION GPS calculation works on the principle of the receiver (example the handheld GPS receiver on car or mobile) calculating the distance of that receiver from a set of known points. 1) The receiver needs to receive a straight line signal (also called line of sight) from the known point without reflection. The best things that can do that are satellites overhead. 2) To enable that‚ the US department of defence has setup 24 low earth orbit (LEO) satellites. They are called the
