If a ball is thrown directly upward with a velocity of 44 ft/s, its height (in feet) after seconds is given by y = 44t 16t2. What is the maximum height attained by the ball? (Round your answer to the nearest whole number.) (I Factor the polynomial completely. P(x) = x2 + 36 P(x) = Find all its zeros. State the multiplicity of each zero. (Order your answers from smallest to largest real, followed by complex answers ordered smallest to largest real part, then smallest to | imaginary part.) X= with multiplicity X = with multiplicity A man is running around a circular track that is 200 m in circumference. An observer uses a stopwatch to record the runner's time at the end of each lap, obtaining the data in the following Time (s) Distance (m) 33 200 72 400 119 600 171 800 227 1000 297 1200 372 1400 449 1600 (a) What was the man's average speed (rate) between 72 s and 171 s? (Round your answer to two decimal places. ) m/s (b) What was the man's average speed between 297 s and 449 s? (Round your answer to two decimal places.) m/s (c) Calculate the man's speed for each lap. Is he slowing down, speeding up, or neither? O slowing down O speeding up O neither Need Help?
