Answer:
an integer is a rational number sometimes(eg.17=17/1) but not always.
a rational number can be written in the form p/q where p and q are integers.
Step-by-step explanation:
Answer:
$712.
Step-by-step explanation:
We have been given that a fund earns a nominal rate of interest of 6% compounded every two years. We are asked to find the amount that must be contributed now to have 1000 at the end of six years.
We will use compound interest formula to solve our given problem.
, where,
A = Final amount,
P = Principal amount,
r = Annual interest rate in decimal form,
n = Number of times interest is compounded per year,
t = Time in years.
![6\%=\frac{6}{100}=0.06](https://tex.z-dn.net/?f=6%5C%25%3D%5Cfrac%7B6%7D%7B100%7D%3D0.06)
Since interest is compounded each two years, so number of compounding per year would be 1/2 or 0.5.
![1000=P(1+\frac{0.06}{0.5})^{0.5*6}](https://tex.z-dn.net/?f=1000%3DP%281%2B%5Cfrac%7B0.06%7D%7B0.5%7D%29%5E%7B0.5%2A6%7D)
![1000=P(1+0.12)^{3}](https://tex.z-dn.net/?f=1000%3DP%281%2B0.12%29%5E%7B3%7D)
![1000=P(1.12)^{3}](https://tex.z-dn.net/?f=1000%3DP%281.12%29%5E%7B3%7D)
![1000=P*1.404928](https://tex.z-dn.net/?f=1000%3DP%2A1.404928)
![\frac{1000}{1.404928}=\frac{P*1.404928}{1.404928}](https://tex.z-dn.net/?f=%5Cfrac%7B1000%7D%7B1.404928%7D%3D%5Cfrac%7BP%2A1.404928%7D%7B1.404928%7D)
![P=711.7802478](https://tex.z-dn.net/?f=P%3D711.7802478)
![P\approx 712](https://tex.z-dn.net/?f=P%5Capprox%20712)
Therefore, an amount of $712 must be contributed now to have 1000 at the end of six years.
I believe the answer is 7920 feet.
I’m assuming there is a picture you are missing.
