A wooded area in a state park has a mixture of different types of trees. There are 800 pine trees and 50 oak trees. The number of pine trees is decreasing at a rate of 5% per year. The number of oak trees is increasing at a rate of 15% per year. If these trends continue:
Write two functions to model this situation, and graph those two functions on the same coordinate grid.
During what year in the future will the park have approximately the same number of pine and oak trees?

Best ResponseYou've already chosen the best response.1look at the function for the pines the 0.05 come from the 5% this time its 0.14 but the number of trees are increasing so its + 0.14

Best ResponseYou've already chosen the best response.1lol I'll do that again N = 800(0.95)^n and N = 800(1.14)^n

Best ResponseYou've already chosen the best response.1how do you think you answer the second part  when number of pines = number of oaks?

Best ResponseYou've already chosen the best response.1when that happens the value N will be the same for oaks and pines

Best ResponseYou've already chosen the best response.1thats 0.15 not 0.14 my last post  i seem to have a fixation with 14!!!

Best ResponseYou've already chosen the best response.1i've made another error for the oak trees the number is 50 not 800 so that the second function is 50(1.15)^n sorry
