Best ResponseYou've already chosen the best response.0looks like you are stuck with analytic geometry :) now lets start with how standard form looks like\[\frac{ y^2 }{ a^2 }  \frac{ x^2 }{ b^2 } = 1\]

Best ResponseYou've already chosen the best response.0My answer choices are: A. y squared over 144 minus x squared over 16 = 1 B. y squared over 16 minus x squared over 36 = 1 C. y squared over 16 minus x squared over 144 = 1 D. y squared over 36 minus x squared over 4 = 1 I'm between B and C

Best ResponseYou've already chosen the best response.0and we know a is 4 so b gotta be 12 since the gradient have to match up

Best ResponseYou've already chosen the best response.0Thanks! @saseal Find the center, vertices, and foci of the ellipse with equation x squared divided by 400 plus y squared divided by 625 = 1.

Best ResponseYou've already chosen the best response.0\[\frac{ x^2 }{ 400 } + \frac{ y^2 }{ 625 } = 1\] this should be easy by now

Best ResponseYou've already chosen the best response.0Ok, so C = 15? @saseal

anonymous

Best ResponseYou've already chosen the best response.0Ok so would my answer be: Center: (0, 0); Vertices: (25, 0), (25, 0); Foci: (15, 0), (15, 0)

anonymous

Best ResponseYou've already chosen the best response.0Or no. It would be: Center: (0, 0); Vertices: (0, 25), (0, 25); Foci: (0, 15), (0, 15

Best ResponseYou've already chosen the best response.0No problem. And I'm in a new chapter so: Find the derivative of f(x) = 6 divided by x at x = 2.

Best ResponseYou've already chosen the best response.0And also: Find the derivative of f(x) = 4x + 7 at x = 5. @saseal
