valentinak56 [21]

Answer:

The foci of the given ellipse = (0 ,-√5 ) and ( 0, √5 )

Step-by-step explanation:

Step(i):-

Given Ellipse 9 x² + 4 y² = 36

$\frac{9x^{2} }{36} + \frac{4y^{2} }{36} =1$

⇒ $\frac{x^{2} }{4} + \frac{y^{2} }{9} = 1$

Step(ii):-

The Major axis lies on y-axis

Foci of the Formula C² = a² -b² = 9-4 =5

C = √5

The Foci is always lie on the major axis(longest) axis, spaced equally each side of the centre

Given ellipse of the foci is lie on Y- axis

Final answer:-

The foci of the given ellipse = (0 ,-√5 ) and ( 0, √5 )
