Step-by-step explanation:

One way to find the union of two sets is to list all the elements of both sets in order, then delete any duplicates.

Here, joining the two sets gives ...

{1, 6, 2, 3, 14, 2, 9, 13, 1}

Putting these elements into numerical order, we have ...

{1, 1, 2, 2, 3, 6, 9, 13, 14}

I have highlighted the duplicates. Deleting those gives us the desired union of the two sets:

X ∪ Y = {1, 2, 3, 6, 9, 13, 14} . . . . . matches choice C

Euler Bank advertises that it compounds interest continuously and that it will double your money in 20 yr. What is the annual in

Romashka [77]

To solve this problem you must apply the proccedure shown below:

1. You must apply the following formula:

$FV=(PV)(e^{it})$

Where $FV$ is the future value, $PV$ is the present value, $i$ is the interest rate and $t$ is the time in years.

2. You have that the bank will double your money in $20$ years. Therefore:

$FV=2PV$

3. Substitute values into the formula and solve for $i$ , as following:

$2PV=(PV)(e^{(i)(20)} \\ 2=e^{(i)(20)}$

4. By applying natural logarithm, you have:

$ln(2)=(i)(20) \\ i= \frac{ln(2)}{20} \\ i=0.0346$

$i=3.46$ %

The answer is: $3.46$ %
