Article: Many well-intentioned people see a blind person on the street and assume they should help. While it's a good idea to be helpful to those around you, you should never help someone without checking if they need assistance first. Approach and ask before you assist.  Approach the blind person first. Greet them and introduce yourself. Say something like, "Hi there! I'm Michael."  From there, politely ask if they need help. Try something like, "I noticed you're trying to cross the street and I was wondering if you needed any help." If the person needs help, he or she will usually let you know. Not all visually impaired people need assistance, so do not be offended if your offer is declined. Simply wish the person a good day and move on. Many blind or visually impaired people have been dealing with their disability for a long time. They are often used to navigating potential threats. While it's important you let a blind person know of a coming car or a low-hanging tree branch, try not to be overly protective. Only advise a blind person to move or duck when it's absolutely necessary. Just as you might enjoy observing the scenery when you walk, many blind or visually impaired people enjoy having scenes described to them. When guiding a blind person, it can be nice to tell them about anything noticeable or interesting as you're walking. However, use discretion. Some people may prefer to walk in silence or may find excessive chatter distracting. It's a good idea to ask first before you describe the scene. Many people use non-verbal cues, like pointing, when giving directions. You may do this without even thinking when giving directions to a blind person. However, try to remember you need to give out specific verbal directions for a blind person to understand. Say, "You walk three blocks forward on this street and then take a left." Do not point forward and say, "It's three blocks that way."

Approach, ask, and then assist. Do not be overprotective. Describe the passing scene. Give directions verbally.
Article: You must determine from the outset whether the added weight of the plants will be something the roof can withstand. You should also find out whether there are any council or municipal vegetative roof restrictions. With vegetation and full saturation, expect the roof to weigh another 20 pounds per square foot of additional weight.    {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/c\/c1\/Build-a-Green-Roof-Step-1Bullet1-Version-2.jpg\/v4-460px-Build-a-Green-Roof-Step-1Bullet1-Version-2.jpg","bigUrl":"\/images\/thumb\/c\/c1\/Build-a-Green-Roof-Step-1Bullet1-Version-2.jpg\/aid688104-v4-728px-Build-a-Green-Roof-Step-1Bullet1-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"<div class=\"mw-parser-output\"><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"} The roof will require an incline to ensure that water runs off naturally and doesn't water log the roof. In general, any roof with a slop of up to 40 degrees is safe to use (providing the previous step's restrictions have been observed.

Consult with a structural engineer to ensure that the joist can handle the changed use for the roof. Check the slope.
Article: In order to calculate the CAGR, first you need to define the period of time for which you want to do the calculation.  Next, you need to know the beginning value of an investment.  Then, find out the ending value of the investment for the time period. Divide the ending value by the beginning value.  Then raise the result to the power of 1 divided by the number of years in the time period.  Finally, subtract 1 from the result. Raising a value to an exponent is done on a calculator by entering the first value, pressing the exponent button (usually represented as xy{\displaystyle x^{y}}), then entering the exponent value and pressing enter. Alternately, you can type the expression into Google using the "^" symbol between the base number and exponent. The search engine will solve it for you. In the example above, the period was three years, from 2012 to 2015.  The beginning value was $10,000.  The ending value was $19,500.  Use the following formula: CAGR=((endingvalue/beginningvalue)1numberofyears)−1{\displaystyle CAGR=((endingvalue/beginningvalue)^{\frac {1}{numberofyears}})-1}  Using the above formula, CAGR=(($19,500/$10,000)13)−1{\displaystyle CAGR=((\$19,500/\$10,000)^{\frac {1}{3}})-1}  This equals (1.950.333)−1{\displaystyle (1.95^{0.333})-1}  This then equals 1.2493−1{\displaystyle 1.2493-1}  Which solves to 0.2493, or 24.93 percent.
