Kathryn invests $8,094 in a savings account with a fixed annual interest rate of 3% compounded continuously. What will the account balance be after 7 years?

• $9,690.28

• $9,403.89

• $9,985.39

• $9,125.96

• exponential growth because r>0

• exponential growth because r<0

• exponential decay because r>0

• exponential decay because r<0

You deposit $5,000 in an account that earns 3% interest compounded continuously. Which equation could be used to determine how much money would be in the account after 8 years?

If $1,000 is invested at 16% interest, compounded continuously, for five years, what is the ending balance?

• $1,225,54

• $2,225.54

• $22,255.40

• $225.54

An initial investment of $800 is compounded continuously at a 2.5% interest rate. Find the value after 10 years.

• $1027.22

Kimi invests $4,000 at 3% interest compounded continuously. How much money will she have in 4 years?

Damara invests $3500 at 2% compounded continuously for 5 years. How much will she have in her account after 5 years?

Categorize the functions into either exponential growth or exponential decay functions.

Groups:
