The speed s in m/s of an athlete can be modeled by the function
s=9.8 - 9.8e 0.8st where t is the time (in seconds) after the athlete
starts running. Graph this model and use the graph to estimate the
speed of the athlete 2 seconds after his launch. Round your answer to
the nearest whole m/s.
speed = m/s

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte
