Problem 3 Got It? Reasoning: In Problem 3, would the model of the exponential data be useful if you did not translate the data by 68 units? Explain.

No; a hot drink in this scenario will not cool below room temperature. In order to use exponential data, it is important to translate the data left 68 units.

No; a hot drink in this scenario will not cool below room temperature. In order to use exponential data, it is important to translate the data up 68 units.

Yes; since a hot drink in this scenario may cool well below room temperature, it is not necessary to translate the data.

Take Note: What is the formula for continuously compounded interest? Enter only the formula. You may use either one of the special characters \cdot or \times (that's not an x) between the P and e in your response.

Take Note: Consider the general formula for modeling continuously compounded interest below.
What does each part of the formula represent?
Match each element in the formula with its description.

Stavka koja se može prevući		Odgovarajuća stavka
e		The amount in the account at time t
A(t)		Principal - the initial amount in the account (in other words, the amount in the account at time 0)
t		An irrational constant approximately equal to 2.72
P		The annual interest rate applied to the account
r		The time that interest has accrued in years

Problem 5 Got It? Scholarships: Suppose you won a contest at the start of 5^th grade that deposited $3000 in an account that pays 5% annual interest compounded continuously. How much will you have in the account when you finish high school 8 years later? Express the answer to the nearest dollar.
