Best ResponseYou've already chosen the best response.0The foci are (plus/minus a*e,0) where the eccentricity e = sqrt(1+ (b^2/a^2))

Best ResponseYou've already chosen the best response.0foci, 4 = 4/e < e = 1 = sqrt( 1 + b^2/3^2)) Solve for b^2

Best ResponseYou've already chosen the best response.1the intercept only works in an ellipse i thought you drew an ellipse

Best ResponseYou've already chosen the best response.0i think you can find by subbing in a point.. but i dunno which point

Best ResponseYou've already chosen the best response.0foci, 4 = 3/e > e = 4/3 = sqrt( 1 + b^2/3^2)) Solve for b^2 So 4/3 = sqt(1 + b^2/3^2) > b^2 = 12/9

Best ResponseYou've already chosen the best response.0they are related by a^2+b^2=c^2 as well right

Best ResponseYou've already chosen the best response.0U can say c^2 = a^2 b^2 (same thing)

Best ResponseYou've already chosen the best response.0Actually, I made mistake in figures: 4/3 = sqrt(1 +b^2/3^2) > 16/9 = 1 + b^2/3^2 > 3^2 * 16/9 = 3^2 + b^2 > b^2 = 3^2 (16/9 1) = 3^2 *7/9 = 7 You can check it here http://www.wolframalpha.com/input/?i=%28x^2%2F3^2%29+++++y^2%2F7+%3D+1
