Question 181633: The formula http://i732.photobucket.com/albums/ww330/school_hard/IMG_49301.jpg
can be used to estimate the number of seconds t it takes a pendulum of lenth L meters to make one complete swing. Graph the equation on a graphing calculator. Then use the graph to estimate the values of t for pendulums of lengths 1.5 meters and 2.5 meters.

+t=2%2Api%2Asqrt%28L%2F9.8%29+

Using the graph,
+t%282.5%29=3.1
+t%283.5%29=3.7+
.
.
or plugging into the equation,
+t%282.5%29=2%2Api%2Asqrt%282.5%2F9.8%29=3.17+
+t%283.5%29=2%2Api%2Asqrt%283.5%2F9.8%29=3.75+
