Four cats – Astro, Buttons, Calico, and Duchess – bought 30 mice altogether. Each of the four cats bought an odd number of mice. Buttons bought more mice than Astro, and Calico bought fewer mice than Duchess. What is the greatest number of mice that could have been bought by Astro and Calico altogether?

.25

step-by-step explanation:

is should be y = 5x

step-by-step explanation:

correct me if im wrong

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.
