Digital information is converted and transmitted in certain numbers that create a pattern. Analog data is transmitted in continuous waves. Old records contain analog data but can be converted to digital recordings. Which of these statements best describes how digital data compares to analog data?
A. Digital data takes more space to store than analog does.
B. Digital data transmits signals more slowly than analog can.
C. Digital data can be stored for a longer period of time than analog can.
D. Digital data records more unwanted background noise than analog does.

Suppose water is leaking from a tank through a circular hole of area ah at its bottom. when water leaks through a hole, friction and contraction of the stream near the hole reduce the volume of water leaving the tank per second to cah 2gh , where c (0 < c < 1) is an empirical constant. a tank in the form of a right-circular cone standing on end, vertex down, is leaking water through a circular hole in its bottom. (assume the removed apex of the cone is of negligible height and volume.) (a) suppose the tank is 20 feet high and has radius 8 feet and the circular hole has radius 2 inches. the differential equation governing the height h in feet of water leaking from a tank after t seconds is dh dt = − 5 6h3/2 . if the height of the water is initially 8 feet, how long will it take the tank to empty? (round your answer to two decimal places.)
