Foci are (0, ±3), e = 3/4, equation of the ellipse is 
 

given

$$\begin{gathered} \mathrm{S}=(\mathrm{o}, \mathrm{be})=(0, 3) \\ \mathrm{be}=3, \mathrm{e}=3/4 \\ \mathrm{b}=4 \\ {{\mathrm{a}}^2}^{ }={\mathrm{b}}^2(1-{\mathrm{e}}^2)=16(1-\frac{9}{16}) \\ {\mathrm{a}}^2=16-9=7 \\ \mathrm{eq}uation of ellipse is \frac{{\mathrm{x}}^2}{{\mathrm{a}}^2}+\frac{{\mathrm{y}}^2}{{\mathrm{b}}^2}=1 \\ \Rightarrow \frac{{\mathrm{x}}^2}{7}+\frac{{\mathrm{y}}^2}{16}=1 \end{gathered}$$
