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,
; Knowing t=0, F=17 and t=6 F=51 (tripling every 6 days (17*3)), 
⇒
, so 
, now if F=130, t=? we have:
Answer:
minimum
Step-by-step explanation:
Given a quadratic function in vertex form
f(x) = a(x - h)² + k
• If a > 0 then f(x) is a minimum
• If a < 0 then f(x) is a maximum
f(x) = 0.25(2x - 15)² + 150 ← is in vertex form
with a = 0.25 > 0
Thus f(x) has a minimum turning point
A = 1/3 * b * h....divide both sides by 1/3h
a / (1/3h) = b
3a / h = b <===
Answer:
A

Glad to help
If you will have any questions about the way I solved it,
don't hesitate to ask
1 1/2 - 1/4
You have to have a common denominator which is 4 in this istance.
That makes it 1 2/4 - 1/4. That equals 1 3/4.
Hope that this helped! :)
