MULTIPLE CHOICE QUESTION
30 sec • 1 pt
Tentukan persamaan elips dengan pusat di titik (2,3) dan sumbu semi-mayor 5 serta sumbu semi-kecil 3.
(x-2)2 /16 + (y-3)2/4= 1
\frac{(x-2)^2}{36} + \frac{(y-3)^2}{9} = 1
\frac{(x-2)^2}{9} + \frac{(y-3)^2}{25} = 1
\( \frac{(x-2)^2}{25} + \frac{(y-3)^2}{9} = 1 \)
