A should be 100.1 and P should be 100, right? P is the amount invested and A is the amount obtained. Also, doesn't this solution assume that interest is compounded daily?
I'm trying to understand the logic, not really the derivation of the formula. Example 1: = [(1 + /)^− 1] / (/) A = future value m = periodic payments r = int rate n = # of compounding periods t = # of years So for this formula I understand it as.. To get future value, we multiply periodic payments by the interest rate (compounded effective ...
Re: Derivative of Trig functions/Compound Interest problems For the first question, you want to compare the future amount of $10,000 invested at 6% compounded yearly with $9,950 invested at 5.9% compounded daily. For simplicity, we will assume a 365 day year.
Hi, is there a way to find out the annual compound interest (A), from the interest (I) over (Y) number of years? For example: If interest over 5 years is 300%, so I=5, Y=3.0, how can I calculate A=? Thanks in advance.
Feb 10, 2018. Last edited by a moderator: Feb 10, 2018. #1. You deposit \$2000 in account A, which pays 2.25% annual interest compounded monthly. You deposit another \$2000 in Account B, which pays 3% annual interest compounded monthly. When is the sum of the balance in both accounts at least \$5000?
So, this is about Amortization Loan. I have this problem below. "On a loan with an interest rate of 12%, compounded monthly, and is being repaid on a monthly basis, the amount of the principal in the 6th payment is $4,000. i. If there are 36 equal payments in all, determine the amount of the...
OP decides to open a savings account and put $200 in each month for 5 years. If the bank pays an interest rate of 3.5% on his account, how much will he have saved up in 5 years? Future value formula right? OP puts $15,000 in a C.O.D that paid a continuous compound interest rate. After 25 years...
We can calculate these for the two hospitals. r 1 = 302 48 ≈ 6.29 c u / b e d. r 2 = 166.5 65 ≈ 2.69 c u / b e d. Clearly hospital one is better at efficiently producing clinical units per bed. You can take the ratio of these rates and see that hospital one has approximately 2.34 the rate of hospital two. This is probably the comparison you ...
(at least within the range of values that allow for S1 and S2 to be equal) Calculating S1 is not a problem, I already have the formula. The hard part is finding B based only on the fact that AB is tangent to the right circle in A and that S1 and S2 have the same area.
One of the ways I amuse myself is writing spreadsheets to solve navigation tasks, a pursuit of no practical value whatsoever in this day and age. One of those I have been playing with is Meridional Parts, one of the formulas for which is: M = 7915.704468 * log tan (45° + {Lat/2}) - 23.268932 * (sin Lat) - 0.0525 * (sin Lat)^3 - 0.000213 ...
