Can a Green Coupon Book Fundraiser Create Green Consumers?
LOS ANGELES, Sept. 19 /PRNewswire/ -- Today, everyone knows it""s cool to be green. It""s in the papers everyday. So why hasn""t the idea of "Green Consumerism" taken hold among middle class Americans?
It""s simple: convenience and price.
An environmentally friendly home improvement store isn""t going to just appear before our eyes. And try finding any selection of "fair trade" clothing or "cruelty free" cosmetics in a department store. Retailers are slow to move towards products that traditionally have lower profit margins.
But someone is out to change all of this. PTA mom, environmental activist and business owner, Jennifer Caronna. She started Fundraising Green with a focus on healthy kids, healthy homes and a healthy planet. Her new fundraising product is a Green Coupon Book. It""s called myGreenSpark Redemption Book and will be available this November. It""s full of coupon offers from Green, Ethical and Healthy businesses that serve Southern California, the U.S. and the world.
When asked to explain, Jennifer had this to say, "Our Green Coupon Book serves many purposes. First, it raises money for our customers in an ethical manner, while promoting Green and Healthy habits. Second, instead of participating in school assemblies that teach them how to shill cookie dough to family and friends, students are exposed to the idea of living green and eating healthy and how both are equally as important in creating healthy communities. Further to this point, our redemption book doubles as an educational tool, with explanations on the stubs of each coupon telling why we as consumers should use this product or service to better our health and the environment. We think that our book will provide the "Green Spark" that families need to see just how easy all of this can be. And finally, when used, the coupons do create "Green Consumers". The more coupons we redeem, the less impact we have on our environment and the healthier we become. We encourage families to explore the contents of the book together. To find a few new products and services, as a family, that will lead them on the path to a Greener, Healthier, Happier lifestyle."
Jennifer is also quick to point out that besides a lot of fun and healthy kids activities, the myGreenSpark Redemption Book is loaded with coupons for everything you need to Green your life. Green your home, your clothes, your kids, your pets, your food and even your vacation. And all with exclusive myGreenSpark discounts. "It""s been so rewarding putting this book together. Business Partners like REI, The Aquarium of the Pacific, Flexcar, Bikestation, No Sweat Apparel, 118 Degrees, TheVegitarianSite.com and Organic Bouquet have been very supportive and are excited about our project."
Jennifer continues, "As the dust settles, we""re seeing that a significant number of our coupon offers are web-based. We""ve come to the conclusion that the Internet offers a very comprehensive and cost effective way to Green the life of most American families. And just think, you never even have to get in your car."
"This gave us an idea. Reaction from around the country has been great. People keep signing up on our website asking us when we""ll have a Green Coupon Book for their area. We""re working on more cities as we speak, but in the meantime, we""ve decided to produce an "Internet Only" version of the myGreenSpark Redemption Book and offer it as a new nationwide eco-friendly fundraiser. At the very least we""ll educate a ton of people. At best we""ll create Green consumers, influence big business to go Green and help in the fight to create a sustainable economy."
The myGreenSpark Redemption Book Fundraiser will be available to schools, clubs, non-profits and foundations this November. It""s a zero administration, web-based fundraiser. Customers never collect any funds or distribute any product, but receive 40% - 50% of the proceeds.

如图，以Rt△ABO的直角顶点O为原点，OA所在的直线为x轴，OB所在的直线为y轴，建立平面直角坐标系．已知OA=4，OB=3，一动点P从O出发沿OA方向，以每秒1个单位长度的速度向A点匀速运动，到达A点后立即以原速沿AO返回；点Q从A点出发沿AB以每秒1个单位长度的速度向点B匀速运动．当Q到达B时，P、Q两点同时停止运动，设P、Q运动的时间为t秒（t＞0）．
（1）试求出△APQ的面积S与运动时间t之间的函数关系式；
（2）在某一时刻将△APQ沿着PQ翻折，使得点A恰好落在AB边的点D处，如图①．求出此时△APQ的面积．
（3）在点P从O向A运动的过程中，在y轴上是否存在着点E使得四边形PQBE为等腰梯形？若存在，求出点E的坐标；若不存在，请说明理由．
（4）伴随着P、Q两点的运动，线段PQ的垂直平分线DF交PQ于点D，交折线QB-BO-OP于点F． 当DF经过原点O时，请直接写出t的值．

如图，在直角梯形OABC中，OA∥CB，A、B两点的坐标分别为A（15，0），B（10，12），动点P、Q分别从O、B两点出发，点P以每秒2个单位的速度沿OA向终点A运动，点Q以每秒1个单位的速度沿BC向C运动，当点P停止运动时，点Q也同时停止运动．线段OB、PQ相交于点D，过点D作DE∥OA，交AB于点E，射线QE交x轴于点F．设动点PQ运动时间为t（单位：秒）．
（1）当t为何值时，四边形PABQ是等腰梯形，请写出推理过程；
（2）当t=2秒时，求梯形OFBC的面积；
（3）当t为何值时，△PQF是等腰三角形？请写出推理过程．

（2011•嘉兴一模）把Rt△ABC和Rt△DEF按如图（1）摆放（点C与E重合），点B、C（E）、F在同一条直线上．已知：∠ACB=∠EDF=90°，∠DEF=45°，AC=8cm，BC=6cm，EF=10cm．如图（2），△DEF从图（1）的位置出发，以1cm/s的速度沿CB向△ABC匀速移动，在△DEF移动的同时，点P从△ABC的顶点A出发，以2cm/s的速度沿AB向点B匀速移动；当点P移动到点B时，点P停止移动，△DEF也随之停止移动．DE与AC交于点Q，连接PQ，设移动时间为t（s）．
（1）用含t的代数式表示线段AP和AQ的长，并写出t的取值范围；
（2）连接PE，设四边形APEQ的面积为y（cm²），试探究y的最大值；
（3）当t为何值时，△APQ是等腰三角形．

（1）AP=2t
∵∠EDF=90°，∠DEF=45°，
∴∠CQE=45°=∠DEF，
∴CQ=CE=t，
∴AQ=8-t，
t的取值范围是：0≤t≤5；

（2）过点P作PG⊥x轴于G，可求得AB=10，SinB=
