The number of students, s, serviced by the school system in the town of emor, t years from 2000 can be
modeled by the function s(t) = 10,000(1.1). the number of classrooms, c in the town of emor, t
years from 2000 can be modeled by the function c(t) = 450 + 40t.
let d be the average number of students per classroom in emor's school system t years from 2000.
write a formula for d(t) in terms of s(t) and c(t).
d(t) =
write a formula for d (t) in terms of t.
d(t) =

any options?

step-by-step explanation:

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.

answer is  

a.

5.2 inches

hope you get this right.
