"A learning curve is a graphical representation of the increase of learning (vertical axis) with experience (horizontal axis). The curve for a single subject may be erratic." - Learning curve. (2013, June 11). In Wikipedia, The Free Encyclopedia. Retrieved 09:59, June 11, 2013 In a learning curve experiment a young girl was introduced to riding a RipStik for the first time. On her very first attempt to ride the RipStik she fell off immediately, a rolling time of zero seconds. On her second attempt she fell off in three seconds. The attempts to ride are experience, the time during which she successfully rolled is the learning.
Experience: Attempt number
Learning: Rolling time (s)

Graph the data, add a LOGARITHMIC trend line and equation to the graph, and then write the logarithmic equation:
____________ Based on the logarithmic equation in part a, calculate the rolling time for attempt number 22.
____________ Based on the logarithmic equation in part a, calculate the attempt number when the young girl will attain a rolling time of 16 seconds.
Solve the equation in part a for x, writing out the resulting inverse equation below:
