A breeding group of beavers is introduced into a protected area. After t years the number of beavers in the area is modeled by the function
N(t)= 54/0.35+0.68^t
1. How many beavers were initially introduced?
2. Estimate the number of beavers after 5 years.
3. Determine the change in the beaver population between t = 5 and t = 10.
(Note: All answers are whole numbers.)

Best ResponseYou've already chosen the best response.0The answers that I have so far are (I am not sure if I did them right): 1. N(t)= 54/0.35+0.68^0 = 40 2. N(t)= 54/0.35+0.68^5 = 109 3. I am not sure?

Best ResponseYou've already chosen the best response.1question #1 you have to evaluate N(0)

Best ResponseYou've already chosen the best response.0yup and for #2 put t=5

Best ResponseYou've already chosen the best response.0as change is n(5)  n(10) put t= 5 and t=10 and subtract

Best ResponseYou've already chosen the best response.1yes! for third part we have to compute this: \[{N\left( 5 \right)  N\left( 0 \right) = ...?}\]

Best ResponseYou've already chosen the best response.0I am not sure exactly how to compute that what do I plug in?

Best ResponseYou've already chosen the best response.1is your formula like this: \[N\left( t \right) = \frac{{54}}{{0.35 + 0.68t}}\]

Best ResponseYou've already chosen the best response.0from 10 to 5 n(10) = 54/(.35+(.68^(10)))

Best ResponseYou've already chosen the best response.0@Michele_Laino that's how my formula is.

Best ResponseYou've already chosen the best response.1sorry ! Is it like below: \[\Large N\left( t \right) = \frac{{54}}{{0.35 + {{0.68}^t}}}\]

Best ResponseYou've already chosen the best response.0yup ^ this power operator.

Best ResponseYou've already chosen the best response.1then if t=0, we have: \[\Large N\left( 0 \right) = \frac{{54}}{{0.35 + 1}} = ...?\]

Best ResponseYou've already chosen the best response.1if t=5, then we have: \[\Large N\left( 5 \right) = \frac{{54}}{{0.35 + {{0.68}^5}}} \cong 109\]

Best ResponseYou've already chosen the best response.0so do I just go 10940=69?

Best ResponseYou've already chosen the best response.1for t=10, we have: \[\Large N\left( {10} \right) = \frac{{54}}{{0.35 + {{0.68}^{10}}}} \cong 145.5\]

Best ResponseYou've already chosen the best response.03. Determine the change in the beaver population between t = 5 and t = 10. here t is 10 and 5 implies 145109 =?

Michele_Laino

Best ResponseYou've already chosen the best response.1so you have to do this: \[\Large N\left( {10} \right)  N\left( 5 \right) = 145.5  109 = ...?\]

Best ResponseYou've already chosen the best response.1yes! @AdityaOS is right!

Best ResponseYou've already chosen the best response.0So the answers are: 1. 40 2. 109 3. 36.5 but isn't 36.5 not in whole number

Best ResponseYou've already chosen the best response.1you can round off 36.5 to 37
