A bird sanctuary used to receive 10,000 birds per year. The number of birds migrating to the sanctuary is decreasing at the rate of 5% each year. Identify the exponential decay function that models the situation. Then find the bird population after 4 years. y = 10000(0.95)t ; 8145

y = 10000(0.95)t ; 8000

y = 10000(0.9)t ; 7900

y = 10000(0.5); 7800

Item 1 which question could the expression 1000n answer? let n = the number of gallons of gas used. how many miles per gallon did the car get driving 1000 miles? let n = the number of grams of food needed for each dog. how many grams of food are needed to feed 1000 dogs? let n = the number of people at the show. how many empty seats were there at the show if there are 1000 seats at the theater? let n = the number of seats at the theater. how many empty seats will there by if 1000 people come to the show?
