future value of 10% savings from earnings of 36000 earns 6.25% annual interest compounded quarterly for 15 years​
hoa [83]

without further ado

10% of 36000 is simply 3600, we chopped a "0" off of it hmmm, ok so

~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill &\$3600\\ r=rate\to 6.25\%\to \frac{6.25}{100}\dotfill &0.0625\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{quarterly, thus four} \end{array}\dotfill &4\\ t=years\dotfill &15 \end{cases} \\\\\\ A=3600\left(1+\frac{0.0625}{4}\right)^{4\cdot 15}\implies A=3600(1.015625)^{60}\implies A\approx 9126.53

Answer:

Welcome to the website. If you're here, you're likely looking to find random words. Random Word Generator is the perfect tool to help you do this. While this tool isn't a word creator, it is a word generator that will generate random words for a variety of activities or uses. Even better, it allows you to adjust the parameters of the random words to best fit your needs.

The first option the tool allows you to adjust is the number of random words to be generated. You can choose as many or as few as you'd like. You also have the option of choosing words that only begin with a certain letter, only end with a certain letter or only begin and end with certain letters. If you leave these blank, the randomized words that appear will be from the complete list.

Another option you have is choosing the number of syllables of the words or the word length of the randomized words. There are also ways to further refine these by choosing the "less than" or "greater than" options for both syllables and word length. Again, if you leave the space blank, the complete list of randomized words will be used.

You have the option of choosing the types of words you want to be displayed using the "Word Type" dropdown. The default is "All" which is a curated list of thousands of the more common English words. You can also opt to only display nouns, verbs, or adjectives from this curated list. If you want to choose from all the words out there, you can choose "Extended" which is a list that includes over half a million different English words.

If you're interested in random words in languages other than English, you can choose the "Non English" word type. Doing so will give you the option to generate words in ten different languages other than English. This includes Spanish words, Hindi words, Arabic words, German words, Russian words, Chinese words, Japanese words, Korean words. Latin words, or Italian words. You simply need to choose the language and then words from that language will randomly appear with each refresh of the page.

Once you have input all of your specifications, all you have to do is to press the Generate Random Words button, and a list of random words will appear. Below are some of the common ways people use this tool.

Games

This tool can be useful for games like Pictionary or MadLibs. Since the words are random, this helps to keep a game like Pictionary fair for all those playing. For a game like MadLibs, it can help kids improve their vocabulary by generating words they may not have ever considered to fill in the blank spaces. The tool has the potential to help with any word game that doesn't require a specific word.

Creative Writing

For those who write, this tool can be an excellent device to aid in the creative writing process. By using the tool to create 5 random words, a writer could then attempt to use all of them in a single paragraph. Longer random word lists could be incorporated into a short story. Since the writer doesn't know which words will appear, creativity must be used to successfully incorporate all the words. To make the challenge even more difficult, the writer could try to use the words in the exact order they were generated. In this way, writers can challenge their creativity to push their writing skills.

Spelling and Vocabulary

This tool can be an excellent way to improve vocabulary or practice for spelling bees. If an unfamiliar word appears, looking up the meaning will help students increase the number of words they know. Working with a partner, students can test each other on the spelling for the randomized words generated.

Name Inspiration

If you need to create a name for a product, an event, a band or for anything else, this tool can be quite helpful. As you consider names, generate a number of random words and see how they impact what you have already come up with. Inputting unique words you may not have considered can spark additional creativity to eventually help you produce the perfect name for your project. If you're looking for good character names or baby names, you might be interested in our random name generator.

The above list is not comprehensive. There are literally hundreds of ways the Random Word Generator can be used. Please feel free to share the way you use this tool, and we always welcome suggestions on how we can improve it to serve you better. We are also interested in new word generators you'd be interested in us creating. Many of the tools on this website came from ideas from people like you who contacted us. Please take the time to explore the other random generators we have available which can be found in the right sidebar of the page.
