Solve the problem. A ball is kicked upward with an initial velocity of 68 feet per second. The ball's height, h (in feet), from the ground is
modeled by h = -1672 +68t, where t is measured in seconds. How much time does the ball take to reach its highest
point? What is its height at this point?
4.25 sec; 72.25 ft
C. 2.125 sec; 144.5 ft
4.25 sec; 216.75 ft
d. 2.125 sec; 72.25 ft

Suppose there is a simple index of three stocks, stock abc, stock xyz, and stock qrs. stock abc opens on day 1 with 4000 shares at $3.15 per share. stock xyz opens on day 1 with 5000 shares at $4.30 per share. stock qrs opens on day 1 with 6000 shares at $4.60 per share. the price of stock abc on day 8 begins at $3.50. the price of stock xyz on day 8 begins at $3.90. stock qrs opens on day 8 with a price of $4.50 per share. assume that each stock has the same number of shares that it opened with on day 1. what is the rate of change of this simple index over 1 week?

You were told that the amount of time lapsed between consecutive trades on the new york stock exchange followed a normal distribution with a mean of 15 seconds. you were also told that the probability that the time lapsed between two consecutive trades to fall between 16 to 17 seconds was 13%. the probability that the time lapsed between two consecutive trades would fall below 13 seconds was 7%. what is the probability that the time lapsed between two consecutive trades will be between 14 and 15 seconds?
