Your high school freshman class consists of 760 students. in recent years only 4 out 7 students actually graduated in four years. approximately how many of your classmates are expected to graduate in four years

why are you giving so many marks make your marks less and make a question list so that i can understand your question very nicely

let's first notice, the center of the hyperbola is at the origin, since the focus points are equidistantly 3 units away from the origin, that also means that the distance "c" from the center to either focus is 3.

it should also be notable that, the traverse axis for this hyperbola is vertical, or namely over the y-axis and therefore, the positive fraction will be the one with y-variable.

the traverse "a" component or distance from the center to either vertex is not 2, is more than 2, so we can safely put it at √5 ≈ 2.24.
