Find the length of the major axis (1/16)(x+2)^2+(1/9)(y-5)^2=1.?

Question

haha another one i wonder how many people actually know this stuff???

Answer 1

(x + 2)²/16 + (y - 5)²/9 = 1

The major axis is along the x-axis, and its length 2 times the square root of the larger denominator: 2 × √16 = 2 × 4 = 8.

The length of the minor axis is 2 times the square root of the smaller denominator: 2 × √9 = 2 × 3 = 6
