Consider the equation open parentheses x minus 2 close parentheses squared equals negative three x plus 6.

Part A

Which expression is a factor of both open parentheses x minus 2 close parentheses squared and negative three x plus 6?

Part B

The size of the population of a certain city was 25,000 in 2010 and decreased by 4% each year afterward.

Part A

The size of the population, y, can be modeled by an exponential function of the form y equals a open parenthesis b to the power of x close parenthesis, where x represents the number of years since 2010 and a and b are constants. What is the value of b?

Enter your answer in the box.

Part B

Suppose the equation representing the size of the population is graphed in the xy-coordinate plane. Which statement is true?

Wesley deposits $2,000 in an account that earns 4.5% annual interest compounded continuously. If no other deposits or withdrawals are made, the amount, A, in dollars, in the account after t years can be modeled by the function A of t equals two thousand e raised to the zero point zero four five t power.

Part A

What is the average rate of change, in dollars per year, of the amount in the account over the first two years? Give your answer to the nearest whole number.

Enter your answer in the box.

$ per year

Part B

The solution to the equation four thousand equals two thousand e raised to the zero point zero four five t power gives the number of years it will take for the amount in the account to reach $4,000. What is the solution to the equation expressed as a logarithm?

Part C

Which interval contains the numbers of years when the amount in the account will first reach $5,000?

Part D

If Wesley wants to have $5,000 in the account after 15 years, how much should he deposit initially, assuming the same interest rate? Give your answer to the nearest whole number of dollars.

Enter your answer in the box.
