MA1210 Mod3 3.1 Quadratic and Exponential Functions 1. Jerry wants to purchase some items whose cost function is C=3x+5, where x is the number of items. If Jerry spends between $50 and $80, find the minimum and maximum number of items that he can purchase. C=3x+5 X=(c-5)/3 answer: 15 items min X=(50-5)/3 x=15 25 items max X=(80-5)/3 x=25 2.

December 8, 2011 Special Amish Buggy Lanes Picture yourself, going 45 miles per hour up a hill in beautiful Lancaster County and at the crest you decide to speed up to make it over, when all of a sudden you rear end into an Amish Buggy occupied by an Amish couple. In doing so, the impact would kill both the couple and the horse at that speed. Four primary types of horse and buggy crashes were identified among the reported 76 crashes in the PennDOT crash database of 2006: rear ending a forward moving buggy, motorists passing a buggy, buggy drivers attempting to cross or enter a main road, and a buggy driver attempting a left turn off the main road. Lancaster County should create and build special lanes for Amish buggies because it is dangerous for both Amish and motorists to travel in the same lane. The Amish are a group of Christian church fellowships that form a subgroup of the Mennonite churches.
