1.) Physics shows that when an object is thrown upward with an initial velocity of v _o then its approximate height is given by this quadratic function. s = 4. 9t² + v_o t + h

A ball is thrown upward from the top of a building 15 meters high, at a velocity of 2.8m/sec. Be sure to show & explain all work. a) Find the maximum height and the time in which it was attained (round to 3 decimal places) b) When does it reach the ground? (round to 3 decimal places) c) Sketch a graph to illustrate the answers.

2.) Find the error(s) and solve the problem correctly. Write the expression in standard form. 5 7 i

Answer: 5 - 5 7 i

3.) How can you tell whether a rational function has a slant asymptote without doing any division?
