Step-by-step explanation:
Part 1) What type of exponential model is Natalie’s situation?
What type of exponential model is Natalie’s situation?
we know that
The formula to calculate continuously compounded interest is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
e is the mathematical constant number
we have
substitute in the formula above
Applying property of exponents
therefore
Is a exponential growth function, because the base is greater than 1
Part 2) Write the model equation for Natalie’s situation
or
see Part 1)
Part 3) How much money will Natalie have after 2 years?
For t=2 years
substitute
Part 4) How much money will Natalie have after 10 years?
