The track team is tryting to reduce their time for a relay race first they reduce their time by 2.1 minutes then they were able to reduce their time by 1/10 their final time was 3.96 minutes what was their begining time

-2 is the right

true

step-by-step explanation:

the correct answer is 1.7

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.
