Answer:
$1,021,337.13
Step-by-step explanation:
The sum of present values of medical expenses is ...
30,000/1.05 +30,000(1.0513)/1.05^2 +30,000(1.0513^2)/1.05^3 +...
So, the series has an initial value of 30,000/1.05 and a common ratio of 1.0513/1.05. Its sum is given by ...
S = a(r^n -1)/(r -1)
where a = 30,000/1.05, n = 35, r = 1.0513/1.05.
Filling in these values and doing the arithmetic, we get ...
S = $1,021,337.13
You need an initial deposit of $1,021,337.13 to cover rising expenses for 35 years.
Answer:
Yes.
Step-by-step explanation:
The triangle inequality theorem states that in order for something to be a triangle, any of it's two sides added together must be greater than the remaining side. Because 4 and 5 are the shortest sides and they satisfy the triangle inequality theorem, you can form a triangle.
223.83 + 318.85 + 63.83 = 606.51
100 - 10 = 90 --> 1 - 0,10 = 0,90
606.51 * 0,90 = 545.859
545.859 * 1,06 = 578.61054 ≈ $ 578.61
Answer:
Step-by-step explanation:
To understand this question you would first of all need to know about negative exponents and multiply fraction by integers.
Example I would like to find out 
,
You would first normally solve this question by squaring, which would result in 4 then divide it by 1. Like this: 
Which would be 0.25 or 1/4
Lets apply this knowledge to the following question:
1. 
2. 
3.
Answer:
Step-by-step explanation:
- 1. c increased by 5 is 5 ⇒ h. c + 5 = 5
- 2. 4 more than a number is 12 ⇒ b. n + 4 = 12
- 3. The product of 4 and n is 12 ⇒ i. 4n = 12
- 4. The difference of 27 and k is 15 ⇒ a. 27 - k = 15
- 5. 8 less than 3 times x is 10 ⇒ f. 3x - 8 = 10
- 6. 3 times x increased by 8 is 20 ⇒ d. 3x + 8 = 20
- 7. A number minus 8 is 3 ⇒ e. k - 8 = 3
- 8. Three times a number is 9 ⇒ j. 3n = 9
- 9. Twice a number plus 1 is 11 ⇒ g. 2x + 1 = 11
- 10. 6 less than a number is 5 ⇒ c. c - 6 = 15
