Suppose that an amount of 10,000 dollars is invested at an annual interest rate of r% compounded continuously for t years. Then the balance at the end of t years is given by f(t,r)=10,000e0.01rt.(a) f:(5, 3)=(Round to an integer.) This number means that, when $10,000 is invested foryears at an annual interest rate of% compounded monthly, if thetime increases by 1 year and the annual interest rate remains constant at% , then the balance in the fund --Select--- v by approximately $(b) f,(5, 3)= 205monthly, if the annual interest rate increases by 1 percent and the time remains constant at 30(Round to an integer.) This number means that, when $10,000 is invested for 50X years at an annual interest rate of 30X % compoundedx years, then the balance in the fund increases vby approximately $ 205

The formula for computing the amount of money in a savings account with an r% annual in- r t erest rate (compounded each year) t years after opening with $P is given by A(t) = P (1 + 100 o compound each year (or annually) means that the interest is computed and added to the ac- ount once a year. The interest the next year is computed on the new account value (with the revious year's interest included). 1. Eloisa plans to put $200 in a savings account with a 3.5% annual interest rate. (a) Write a function for how much money will be in the account in t years. (b) How much will be in the account after 5 years? (c) How long will it take to have $400 in the account? Explain how you found your answer.
There is a relationship between mortgage amount, number of payments, amount of each payment, how often each payment is made, and the interest rate. The following formula illustrates the relationship: PV= R[1-(1+i)"] i • PV = present value ⚫ i = interest rate per compounding period, as a decimal R = payment amount • n = number of payments Suppose a bank offers you a 3.4% interest rate, compounded semi-annually, on a mortgage amount of $173 112. You pay $1000/mo, or $6000 semi-annually. How long, in years, would it take to pay off the mortgage? a. 80 years b. 60 years c. 20 years od. 40 years e. 10 years A X
Marwan provides a donation of $6556 to a college with the provision that a scholarship is paid at the end of each year. If the money is invested at 11.6% compounded annually, then the annual scholarship is: O 1901.24 O 1140.74 O 760.50 O380.25 O 1520.99 If f(x) – x* and g(x) = 10- 3x, then the value of f(5) + g(5) is 130 0.125 120
A savings account with an interest rate r, which is compounded n times per year, and begins with P as the principal (initial amount), has the discrete nt compounding formula A (t) = P(1+)". This is n because we multiply the amount by itself plus a small amount, determined by the interest rate, and the account grows each time the compounding occurs. For continuous compounding, we use the formula A (t) = Pert , and if we have seen this formula before, we may not have gotten a satisfactory answer as to why we use it, other than some vague notion of "compounding infinity times per year". In this exercise, we'll use Bernoulli's Rule to find the connection. It might be helpful to review the "Indeterminate Powers" section of the video before beginning. Why can we write nt lim,→00 P(1+ )"t P limn¬∞ (1+)™ ? n
