The relation is proportional
Josh ||| Tillery
___________
14 ||| 7
16 ||| 9
18 ||| 11
20 ||| 13
Answer:
The constant of proportionality is 5.
Step-by-step explanation:
If the quantity q varies inversely with the square of m and directly with the product of r and x, then the variation equation is
![q=k\frac{rx}{m^2}](https://tex.z-dn.net/?f=q%3Dk%5Cfrac%7Brx%7D%7Bm%5E2%7D)
When q=2.5, m= 4 and the
product of rx = 8.
We plug in this values to get;
![2.5=k(\frac{8}{4^2})](https://tex.z-dn.net/?f=2.5%3Dk%28%5Cfrac%7B8%7D%7B4%5E2%7D%29)
![2.5=k(\frac{8}{16})](https://tex.z-dn.net/?f=2.5%3Dk%28%5Cfrac%7B8%7D%7B16%7D%29)
![2.5=\frac{1}{2}k](https://tex.z-dn.net/?f=2.5%3D%5Cfrac%7B1%7D%7B2%7Dk)
Multiply both sides by 2
![k=2.5\times 2=5](https://tex.z-dn.net/?f=k%3D2.5%5Ctimes%202%3D5)
The constant of proportionality is 5.
