Question

The equation of an ellipse is shown (I'll post it in a minute). What is the length of it's major axis?

Answer 1

Eyeball problem. 30

Just recognize the form. 225 = a^2 ==> a = 15 ==> 2*a = 30

Answer 2

\[\frac{ (x-60)^2 }{ 256 } + \frac{ (y-34)^2 }{ 196 } = 1\]

Answer 3

what is root of 256 ??

Answer 4

16 is the length of major axis

Answer 5

?? \(\sqrt{256} = 16 = a\)

\(Length\;of\;Major\;Axis = 2a = 2(16) = 32\)

Again, this is an eyeball problem. Just look at it and write down the answer.
