Step-by-step explanation:
i = interest 3% for 30 years
This is a simple dynamical system for whom the the solutions are given as
![S=R[\frac{(i+1)^n-1}{i}](i+1)](https://tex.z-dn.net/?f=S%3DR%5B%5Cfrac%7B%28i%2B1%29%5En-1%7D%7Bi%7D%5D%28i%2B1%29)
putting values we get
S=2000[\frac{(1.03)^{30}-1}{0.03}](1.03)
= $98005.35
withdrawal of money takes place from one year after last payment
To determine the result we use the present value formula of an annuity date
![P = R\frac{1-(1+i)^{-n}}{i}{i+1}](https://tex.z-dn.net/?f=P%20%3D%20R%5Cfrac%7B1-%281%2Bi%29%5E%7B-n%7D%7D%7Bi%7D%7Bi%2B1%7D)
we need to calculate R so putting the values and solving for R we get
R= $6542.2356
1) tan 41°= 30cm divide by y cm
y= 30 divide by tan-1 41°
This is just to easy the correct answer is A
6 days* 24 hours per day= 144 hours
Final answer: 144 hours
The <em>correct answer</em> is:
400,000.
Explanation:
The third digit in 399 is 9. To round to this place value, we inspect the digit behind it. If the digit is 5 or greater, we round up; if it is less than 5, we round down.
The digit behind 9 is 7. Since it is greater than 5, we round up. This would ordinarily put the number up 1; however, doing that makes the 9 a 10, which in turn makes the next number 10, and the next number 4. This gives us 400,000.
