Question

(a) Use this information to write a variation equation. Use for weight and for height. Round the value of the proportionality constant, , to two decimal places.

Answer 1

In this case, the variation equation is the following:

`w=kh`

using the statistics, we have that w = 191, and the height converted in feet is h = 69.4, then, the constant of proportionality is:

`\begin{gathered} 191=69.4k \\ \Rightarrow k=(191)/(69.4)=2.75 \\ k=2.75 \end{gathered}`

therefore, the proportionality constant is k = 2.75
