Q. P(t)=4.87(1.02)tThe function models P, the population, in millions, of the city of Melbourne t years after 2019 . Which of the following statements is the best interpretation of the ordered pair (4,5.27) ?Choose 1 answer:(A) The model predicts that the population of Melbourne will increase by 4 percent per year for 5.27 years after 2019 .(B) The model predicts that the population of Melbourne will increase by 5.27 percent per year for 4 years after 2019.(C) The model predicts that the population of Melbourne will be 4 million 5.27 years after 2019 .(D) The model predicts that the population of Melbourne will be 5.27 million 4 years after 2019 .
Plug in t=4: Plug in t=4 into the function P(t)=4.87(1.02)t to see if P equals 5.27.P(4)=4.87(1.02)4
Calculate 1.02: Calculate 1.02 to the power of 4. (1.02)4≈1.08243216
Multiply 4.87: Multiply 4.87 by 1.08243216 to find P(4).P(4)≈4.87×1.08243216
Perform the multiplication: Perform the multiplication to find the value of P(4).P(4)≈5.2716647
Compare with ordered pair: Compare the calculated value of P(4) with the second value in the ordered pair (4,5.27). The calculated P(4) is approximately 5.27, which matches the ordered pair.
Interpret the ordered pair: Interpret the ordered pair (4,5.27) based on the function P(t). The ordered pair (4,5.27) means that 4 years after 2019, the population of Melbourne is predicted to be 5.27 million.
