The population of insects in alaska,?

Question

is P = 13500 + 2200ln(t+1), where t is the time in years from the present. In how many years will there be 18000 insects in this region? Round to the nearest tenth of a year.

Answer 1

sounds like my nose will bleed if i try to answer such question.     :)

Answer 2

here is your solution dude :

your equation : p=13500+2200ln(t+1)

if no of insects equals 18000,     18000=13500+2200ln(t+1)

                                                        18000-13500=2200ln(t+1)

                                        implies    4500 = 2200ln(t+1)

                                        implies    2.04545 = ln (t+1)

                                        implies    t+1 = 7.7326

                                        implies    t=6.7326

                                  rounded to the nearest tenth implies

                                                         t=10

Therefore the insects will be 18000 in number in about 10 years.

Answer 3

"The Handsome Boy" was doing so well until he got to his last step, where he rounded to the nearest 10 years instead of the nearest TENTH.  So the answer would instead be 6.7 years.
