Pleasantburg has a population growth model of p(t)=at2+bt+p0 where p0 is the initial population. suppose that the future population of pleasantburg t years after january 1, 2012, is described by the quadratic model p(t)=0.9t2+6t+14,000. in what month and year will the population reach 21,100?

Atype of plant is introduced into an ecosystem and quickly begins to take over. a scientist counts the number of plants after mmonths and develops the equation p(m)= 19.3(1.089)^m to model the situation. most recently, the scientist counted 138 plants.assuming there are no limiting factors to the growth of the plants, about how many months have passed since the plants werefirst introduced? a)o 6.1b)0.6.6c)10 72d)o 23.1
