Arecipe calls for 350 milliliters of milk. ms. buback has exactly 0.5 liters of milk in her refrigerator. after she makes the recipe, how many liters of milk will she have left?

there are 1000 mL in 1 Liter.

0.5 L is then just 500 mL, half of 1000 mL.

then she uses 350mL, so what's left is 500 - 350 = 150 mL.

how many Liters is that?  150/1000 = 15/100 = 0.15 Liters.

answer: -8.2562234e+13

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.
