Harper is recording temperatures for science class every hour. On Monday the temperature changed at a rate of -4 degrees F per hour. How long did it take for the change in temperature to be -28 degrees F.

abby has a greater debt becasue she owea 5 more then alan does

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.
