A camera is placed in front of a hyperbolic mirror. The equation of the hyperbola that models the mirror is y^2/16-x^2/9=1, where x and y are in inches. The camera is pointed toward the vertex of the hyperbolic mirror and is positioned such that the lens is at the nearest focus to that vertex. The lens is __ inch(es) from the mirror

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

they disappear if your absent from to long. i found out that the hard way.

brainliest lol i just need one more brainliest.
