Q4 (5 points) Consider the following model for the growth or decline of a population y at time I. g = ( 2000)(4000 y) a) What is the minimum sustainable population? b) What is the maximum sustainable population? ( ( (c) On what intervals for y does the population grow? (d) On what intervals for y does the population decline? ( e) When is the p0pulation stable? 05 (5 points) Experimental data indicates that the total leaf area A of a tree is proportional to its stem diameter 3 according to the model A(s) = c3134, where c is a constant of proportionality. Find the percentage error in the calculated area when the error in measuring the stem diameter is at most 5%
