When practicing an oral presentation, you want to make sure to do all of the following except speak with confidence. smile at your audience. read from your notes. speak slowly and clearly.

The answer depends on how you do presentations, but I mainly think it is Reading from your notes, because it's better if you memorize your presentation, and look prepared.

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
