((x-3)^2)/(225)+((y+9)^2)/(121)=1

\frac{( x - 3 ) ^{2}}{225} + \frac{( y + 9 ) ^{2}}{121} = 1

(h, k) = (3, - 9), a = 15, b = 11

Solution steps

\frac{( x - 3 ) ^{2}}{225} + \frac{( y + 9 ) ^{2}}{121} = 1

Rewrite

\frac{( x - 3 ) ^{2}}{225} + \frac{( y + 9 ) ^{2}}{121} = 1

in the form of the standard ellipse equation

\frac{( x - 3 ) ^{2}}{1 5 ^{2}} + \frac{( y - ( - 9 ) ) ^{2}}{1 1 ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (3, - 9), a = 15, b = 11

a > b

therefore

a

is semi-major axis and

b

is semi-minor axis

Ellipse with center (h, k) = (3, - 9), a = 15, b = 11
