Answer:
a. The population does not become extinct in finite time.
Step-by-step explanation:
The model for the population of the fishery is
If we rearrange and replace the constants we have:
Now we can calculate if the population become 0 in any finite time
To be a finite time, t>0
We can conclude that the only finite time in which P=0 is when the initial population is 0.
Because P0 is a positive constant, we can say that the population does not become extint in finite time.
Answer:
a)
b)
c) where
= number ties finished per unit time
d) t≅8.24min
e) K=109tie
J=91tie
f) K≅16.6min
J≅9.09min
Step-by-step explanation:
Data
Kara begins ten minutes before julie, so when julie joins kara she has 60 ties
t=10
a)
b)
c) where
= number ties finished per unit time
d) if kara already has 60 ties and makes 6 per minute and Julie makes 11 per minute then per minute they makes 17 ties, so one minute per 17 ties for 200 ties ¿how long?. ≅8.24min
e) K=60tie+6tie/min*8.24min=109tie
J=11tie/min*8.24min=91tie
f) K=100tie*min/6tie≅16.6min
J=100tie*min/11tie≅9.09min
Note: the amount of ties were rounded to the nearest decimal
