Answer:
t=11,11 days
Step-by-step explanation:
F=frogs poblation, t=time, be the variables dF/dt = KF, dF/F=Kdt, integrating  ⇒ LnF=Kt+c,
⇒ LnF=Kt+c, ; Knowing t=0, F=17 and t=6 F=51 (tripling every 6 days (17*3)),
; Knowing t=0, F=17 and t=6 F=51 (tripling every 6 days (17*3)),  ⇒
⇒ , so
, so  , now if F=130, t=? we have:
, now if F=130, t=? we have:

Answer:
J is midpoint 
side FJ = side JH    Def of midpoint 
angle GJF = GJH    perpendicular bisector both 90 degrees 
JG=JG     reflexive property 
Therefore triangle FJG = HJG
