Solution
- The solution steps are given below:
![\begin{gathered} y\propto\frac{1}{x^2} \\ \\ \therefore y=\frac{k}{x^2} \\ where,\text{ }k\text{ is the constant of proportionality} \\ \\ when\text{ }x=1,y=\frac{7}{4} \\ \\ \frac{7}{4}=\frac{k}{1^2} \\ \\ \therefore k=\frac{7}{4} \\ \\ \text{ Thus, we can say} \\ y=\frac{7}{4x^2} \\ \\ \text{ Thus, when }x=3,\text{ we have:} \\ y=\frac{7}{4(3^2)} \\ \\ y=\frac{7}{4\times9} \\ \\ \therefore y=\frac{7}{36} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20y%5Cpropto%5Cfrac%7B1%7D%7Bx%5E2%7D%20%5C%5C%20%20%5C%5C%20%5Ctherefore%20y%3D%5Cfrac%7Bk%7D%7Bx%5E2%7D%20%5C%5C%20where%2C%5Ctext%7B%20%7Dk%5Ctext%7B%20is%20the%20constant%20of%20proportionality%7D%20%5C%5C%20%20%5C%5C%20when%5Ctext%7B%20%7Dx%3D1%2Cy%3D%5Cfrac%7B7%7D%7B4%7D%20%5C%5C%20%20%5C%5C%20%5Cfrac%7B7%7D%7B4%7D%3D%5Cfrac%7Bk%7D%7B1%5E2%7D%20%5C%5C%20%20%5C%5C%20%5Ctherefore%20k%3D%5Cfrac%7B7%7D%7B4%7D%20%5C%5C%20%20%5C%5C%20%5Ctext%7B%20Thus%2C%20we%20can%20say%7D%20%5C%5C%20y%3D%5Cfrac%7B7%7D%7B4x%5E2%7D%20%5C%5C%20%20%5C%5C%20%5Ctext%7B%20Thus%2C%20when%20%7Dx%3D3%2C%5Ctext%7B%20we%20have%3A%7D%20%5C%5C%20y%3D%5Cfrac%7B7%7D%7B4%283%5E2%29%7D%20%5C%5C%20%20%5C%5C%20y%3D%5Cfrac%7B7%7D%7B4%5Ctimes9%7D%20%5C%5C%20%20%5C%5C%20%5Ctherefore%20y%3D%5Cfrac%7B7%7D%7B36%7D%20%5Cend%7Bgathered%7D)
