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

\( \frac{(x-2)^2}{25} + \frac{(y-3)^2}{9} = 1 \)
