The fox population in a certain region has a relative growth rate of 4% per year. It is estimated that the population in year 20
den301095 [7]

Answer:

a) P(t) = 17900e^{0.04t}

b) The population estimated in 2008 is of 24651.

Step-by-step explanation:

The population growth model may be given by the following exponential function:

P(t) = P_{0}e^{rt}

In which P(t) is the population after t years, P_{0} is the initial population and r is the growth rate.

(A.) Find a function that models the population t years after 2000 (t=0 for 2000)

We have that:

P_{0} = 17900, r = 0.04. So

P(t) = P_{0}e^{rt}

P(t) = 17900e^{0.04t}

(B.) Use the function from part A to estimate the fox population in the year 2008.

2008 is 8 years after 2000. So:

P(8) = 17900e^{0.04*8} = 24650.5

The population estimated in 2008 is of 24651.

How to estimate 96 Times 34 what is the answer
Marrrta [24]

When it says to estimate, I always think of doing it by hand to show work.  So set it up like this:

  96

<u>x 34</u>

So follow it out multiplying across 4*6 and 4*9 carrying over as needed to get it to look like this:

  96

<u>x 34</u>

384


Do the same for the 3 to get this:

  96

<u>x 34</u>

  384

2880

Add 384+2880=3264

Your final answer is 3,264
