To buy a car for $36,000 Stacy use your credit card which charges 20% interest and borrowed the restroom and all my bank the charges 4.5% interest if she pays $2178 in interest the first year, how much did she put on her credit card

answer: 12   they all have at least 28 days

step-by-step explanation: haha

the answer is 40.

proof:

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.
