(x^2)/(1^2)+(y^2)/(sqrt(0.4375)^2)=1

\frac{x ^{2}}{1 ^{2}} + \frac{y ^{2}}{0.4375 ^{2}} = 1

(h, k) = (0, 0), a = 1, b = 0.4375

Solution steps

\frac{x ^{2}}{1 ^{2}} + \frac{y ^{2}}{( 0.4375 ) ^{2}} = 1

Rewrite

\frac{x ^{2}}{1 ^{2}} + \frac{y ^{2}}{0.4375 ^{2}} = 1

in the form of the standard ellipse equation

\frac{( x - 0 ) ^{2}}{1 ^{2}} + \frac{( y - 0 ) ^{2}}{( 0.4375 ) ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (0, 0), a = 1, b = 0.4375

a > b

therefore

a

is semi-major axis and

b

is semi-minor axis

Ellipse with center (h, k) = (0, 0), a = 1, b = 0.4375

22 x^{2} + 66 y^{2} + 60 x + 4 y - 9 = 0

x^{2} + 2 y^{2} - 5 = 1

\frac{x ^{2}}{841} + \frac{y ^{2}}{484} = 1

\frac{x ^{2}}{1.586 9 ^{2}} + \frac{y ^{2}}{0.9 9 ^{2}} = 1

\frac{x ^{2}}{81} + \frac{y ^{2}}{77} = 1
