The bear population in ri has been increasing by 8% each year. in the year 2010 there were only 20 bears spotted in ri. based on this info, a. create a function a(t) that represents the bear pop, t years since 2010b. determine bear pop in 2020c. find out when there are more than 100 bears

See below in bold.

Step-by-step explanation:

a.  The factor of growth = 1.08 per year so

P =  20(1.08)^t   where P = the bear population and t = the time in years since 2010.

b.  It is 10 years after 2010 so:

In 2020:  P = 20 * (1.08)^10

= 43 bears.

c. When P = 100 we have:

100 = 20 * (1.08)^t    

(1.08)^t = 100/20 = 5

t ln 1.08 = ln 5

t =  20.9  years.

So there will be more than 100 bears in the year 2010 + 21

= 2031.

4 adults and 12 babies

step-by-step explanation:

4 x 7 = 28

12 x 15 = 180

180 + 28 =208

4 x 3 = 12
