5. 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:
a. write two functions to model this situation and graph those two functions on the same coordinate grid. two functions for this model would be:
y = 800(.95)^x
y = 50(1.15)^x
b. during what year in the future will the park have approximately the same number of pine and maple trees?
