I need help answering the four questions below

Question #1

Solve the given problem related to compound interest. Find the balance if $4500 is invested at an annual interest rate of 2.5%, compounded annually, after the following number of years. (Round your answers to the nearest cent.) (a) 5 years $ (b) 12 years $Solve the given problem related to population growth. During the first decade of this century, the population of a certain city grew exponentially. The population of the city was 144,430 in 2000 and 218,425 In 2010. Find the exponential growth function that models the population growth of the city. Use t - 0 to represent 2000, t - 10 to represent 2010Ir and so on. (Round k to ve decimal places.)- rum - Use your exponential growth function to predict the population of the city in 2016. Round to the nearest thousand. Solve the given problem related to compound interest. Find the balance if $3800 is invested at an annual rate of 6% for 8 years, compounded continuously. (Round your answer to the nearest cent.) $Nethon's Law of Cooling states that if an object at temperature To is placed intJo an environment at constant temperature A, then the temperature of the object, T(t) (In degrees Fahrenheit}, aFter t minutes is given by T(t) - A. + (TD Ayekt, where k Is a constant that depends on the object. (a) Determine the constant k (to the nearest thousandth) for a canned soda drink that takes 5 minutes to cool from 71F to 61F after being placed in a refrigerator that maintains a constant temperature of 39F. k - (b) What will be the temperature (to the nearest degree) of the soda drink after 30 minutes\":I F (c) When (to the nearest minutJe) will the temperature of the soda drink be 43F? min
