Conservationists will take snow geese off the endangered species list when the population hits 10,000. if populations are sustaining growth at r = 0.088 and the population in 2001 is 3000 individuals, in what year will snow geese be taken off the endangered species list?

a) between 2106 and 2109

b) between 2009 and 2012

c) between 2012 and 2015

d) between 2015 and 2018

the answer is c, but can someone show which formula to use and how you got to final answer?

C) between 2012 and 2015

Explanation:

The population of snow geese as a function of the time 't' in years is given by the following equation:

With t=0 happening in 2001

For the snow geese to be taken off the endangered species list, P(t) = 10,000:

The population will reach 10,000 animals 13.68 years after 2001, that is "2014.68". This means that the population will reach 10,000 between 2014 and 2015.

Therefore, the answer is C) between 2012 and 2015

relationships aren't everything. people everyday spend there entire life depending on reltionships and for someone to be there for them when this is absurd. why must people depend on someone else to bring them happiness? i'm not saying it wrong to feel happy with someone, but people feel that they need to be in a relationship in order to feel happy, when, this is not true. you can paint, write, read ir slend tume with family ir even spend time working in yourself. this can be an exciting experience to find yourself. it's bot wrong to be in a relationship but if you let it be your only source of happiness, than you will never find true happiness.

so, relationships are not always worth it. if you are so dependent on them, than in the end they arent worth it because you will realize how unhappy you really were. some people even tend to cut ties with family because they think they cabt make them happy, obly realtionships with a lover can. false. in order to find true happiness, one must learn to love themselves if they want to love someone else. it's unhealthy to be always depend on relationships and to alqays be in and out of one.

so live life, get that job you always wanted, buy those new shoes and love yourself. depend on yourself, not others. they arent worth it, you can make yourself more happier than most people can do to you. it's not woth it. take your time and have fun.

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
