Answer» Given : The population of deer on an island is given by p(X)=100(0.85)^x To find : the PERCENT of CHANGE for the population of deer per year. Solution: population of deer on an island is given by p(x)=100(0.85)^x Population after n year = 100(0.85)ⁿ Population after n+1 year = 100(0.85)ⁿ⁺¹ Change in population = 100(0.85)ⁿ⁺¹ - 100(0.85)ⁿ = 100(0.85)ⁿ( 0.85 - 1) = 100(0.85)ⁿ(-0.15) = 15(0.85)ⁿ % change in population = 100 x (-15(0.85)ⁿ) / 100(0.85)ⁿ = -15 % -ve sign shows decrease Hence 15 % decrease in population every year Learn More: What is the percent change when 15 0 is decreased to135 full ... in a furniture shop 24 were bought at the rate of rupees per table the ... |
