Body mass index (BMI) is a measurement that helps determine obesity, with a BMI of 30 or greater indicating that the person is obese. BMI is directly proportional to the weight of a person of a given height. 

 

a. if the BMI of a person who id 1.7 meters tall is 20 when the person weighs 55 kilograms, what is the constant of the variation?

b. The person of this height has a BMI of 32, what do they weigh?

a. The constant variation is ?

b. The person weighs ? kg.

Graph the rational function x+ 2 Objective: (A5) Graph Rational Functions Use synthetic division to find the quotient and remainder when the first polynomial is divided by the second. 2) x2-2x+4, x-7 Objctive: (32) Use Synthetic Division Solve the problem. 3) Body-mass index, or BMI, takes both weight and height into account when assessing whether an indivi underweight or overweight. BMI varies directly as one's weight, in pounds and inversely as the square height, in inches. In adults normal values for the BMI are between 20 and 25.
