0.8x^2+y^2=9

0.8 x^{2} + y^{2} = 9

(h, k) = (0, 0), a = 3.35410 \dots, b = 3

Solution steps

0.8 x^{2} + y^{2} = 9

Rewrite

0.8 x^{2} + y^{2} = 9

in the form of the standard ellipse equation

\frac{( x - 0 ) ^{2}}{3.35410 \dots ^{2}} + \frac{( y - 0 ) ^{2}}{3 ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (0, 0), a = 3.35410 \dots, b = 3

a > b

therefore

a

is semi-major axis and

b

is semi-minor axis

Ellipse with center (h, k) = (0, 0), a = 3.35410 \dots, b = 3

3 x^{2} - 6 x + y^{2} + 4 y - 11 = 0

7 x^{2} + 16 y^{2} + 28 x - 128 y + 172 = 0

\frac{( x + 2 ) ^{2}}{16} + \frac{y ^{2}}{49} = 1

9 x^{2} + 36 x + y^{2} + 2 y + 36 = 0

4 y^{2} + x^{2} = 8
