A water wheel traps a fish and spins around periodically dunking the fish in the water. Suppose the diameter of the wheel is 6 meters and the wheel is submerged 1 meter into the water. The wheel rotates 5 times in 1 minute.
a) What is the diameter of the water wheel?
b) How long does it take the fish to complete one revolution of the wheel?
c) Does the fish reenter the water? If so, for approximately how long?
d) After 36 seconds, at what height will the fish be?

You drop a rubber ball off the roof of a 50 meter high building onto a paved parking lot. it bounces back up with every bounce, but not quite all the way back up to you. after the first bounce it bounces back only 80 percent of the distance it was dropped from. the pattern continues, meaning after every bounce it comes up to just 80 percent of the previous maximum height. so if before the first bounce the height is 50 meters, what height does the ball reach after the fifth bounce? round your answer to one decimal place and chose the correct response from the choices below:

The random variable x is the number of occurrences of an event over an interval of ten minutes. it can be assumed that the probability of an occurrence is the same in any two-time periods of an equal length. it is known that the mean number of occurrences in ten minutes is 5.3. the appropriate probability distribution for the random variable

How do i start to solve? would appreciate a walk-thru! a bird sitting 16ft above the ground in an apple tree dislodges an apple. after how many seconds does the apple land on the ground? (assuming that no branches will interfere with it's fall)
