The answer for 2^-4 is 1/16
Answer:
I can use variables to represent the coordinates of the vertices for a general triangle, ∆ABC. Then I can calculate the midpoints of the sides in terms of those variables. Using the point-slope formula for the equation of a straight line, I can build the symbolic equations for the three medians, AE, BF, and CD. I can solve for the point of intersection for two of the medians, AE and BF, for example. Finally, I can prove the lines (i.e., medians) concurrent if the point I found also satisfies the equation of the line for CD.
There are 5280 feet in a mile. Knowing this, we can make the conversion from 2640 feet per hours to miles per hour:
(2640/5280)/1 hour = 0.5 miles / hour
