For functions, x’s can’t repeat, so looking at the first problem, C is the only one where the first number in each coordinate (x,y) doesn’t repeat.
For the second, x = -2 means that no x is always -2 matter which y you would look at. So x’s repeat and it forms a vertical line. So it is not a function
Answer:
The correct answer is B
Step-by-step explanation:
She starts with 29 because 29 don't have an valuable with it and she gains 12 every year, year is represented by the k. The Greater than equal to sign makes the problem can't equal anything under 120.
Answer: f(5x)=(50x^2)-5
Step-by-step explanation:
f(5x)=2(5x)^2-5
=2(25x^2)-5
=50x^2-5
Find attached the missing cash flow stream
Answer:
- <u><em>Present value = $1,685,334 (rounded to the nearest whole)</em></u>
Explanation:
Since the <em>cash flow stream</em> is <em>uneven</em>, you must discount each stream individually and after you have discounted every stream you can add each preset value to find the net present value.
The formula for <em>present value</em> is:

<u>1. Year 1:</u>
- Future value = $250,000
- r = 4%
- n = 1

<u>2. Year 2:</u>
- Future value = $20,000
- r = 4%
- n = 2

<u>3. Year 3:</u>
- Future value = $330,000
- r = 4%
- n = 3

<u>4. Year 4:</u>
- Future value = $450,000
- r = 4%
- n = 4

<u>5. Year 5:</u>
- Future value = $550,000
- r = 4%
- n = 5

<u>6. Year 6:</u>
- Future value = $375,000
- r = 4%
- n = 6

Total present value = $240,384.62 + $18,491.12 + $293,368.80 + $384,661.89 + $452,059.91 + $296,367.95 + $ 296,367.95
Total present value = $1,685,334.29 = $ 1,685,334
