# How to create a hyperlink

Something that I have been noticing is that people are having trouble using a hyperlinks. Below is a brief tutorial on how to do this properly. Feel free when you commenting on each other’s posts to try uploading another link (even if it’s just to google).

2. highlight the address. When this happens you should be able to click on the tool that looks like a paper clip on above the text book.

3. It will ask you for a URL from there you can type or copy and past the URL from the link you are choosing to use.

4. make sure on the format section seen on the right side of your page you have clicked link. Usually most posts are automatically set to standard.

If there are any additional Questions please do not hesitate to contact me.

# Math equations

One of the topics of the course will be on exponential functions. Understanding exponential functions can allow you to quantitatively describe the growth structure of a model. You will not have a problems that look like this, however showing your work will be vital.

Question: f(x)= 5×
log²(5)+ 5log²(3)= log²(5) + log²(3⁵)=
log²(5×3⁵) or log²(1215)

Edits by John Roe: here is how to use LaTeX/MathJax to display these

[ f(x) = 5^x. ]

[ log(5) + 5log(3) = log(5) + log(3^5) = log(5times 3^5) = log(1215). ]

# How Much Water Does it Take to Make a Pair of Jeans?

Water rights and accessibility is no doubt a global issue. Despite it being in the news, day to day when we wash our face or dishes we rarely think about how much we are wasting. However even if you are water conscious at home its more likely that you do not think about how much water is being wasted when you buy products.

Indirectly we can waste water, whether its buying agriculture from fields which do not have a efficient irrigation systems, or from buying a pair of jeans.  ” It takes around 1,800 gallons of water to grow enough cotton to produce just one pair of regular ol’ blue jeans.” That’s more water than it takes to make a ton of cement or a barrel of beer (although I’m sure some of you do not consume this yet).  And that’s just in terms of growing cotton, when you take into account the dye process as well as the machine wash almost 9,982 gallons of water are used.

How can we fix this?

1. stop purchasing so many jeans

2.  Buy levis, they are built to last, and its strongly recommended to not machine wash them. They suggest freezing them instead, it kills all the germs. however, if  there is a grass stain that you would like to get off all it takes is a sponge and a cup of water opposed to 40 gallons ( a typical machine wash).
