Suppose the depth of the tide in a certain harbor can be modeled by y = 23 - 5 cos pi/6 t, where y is the water depth in feet and t is the time in hours. Consider a day in which t = 0 represents 12:00 midnight. For that day, when are high tide and low tide and what is the depth of each?
a.
high tide at 6:00 a. m. and 6:00 p. m., depth 28 ft
low tide at 12:00 noon and 12:00 midnight, depth 18 ft
b.
high tide at 6:00 a. m. and 6:00 p. m., depth 23 ft
low tide at 12:00 noon and 12:00 midnight, depth 5 ft
c.
high tide at 12:00 noon and 12:00 midnight, depth 28 ft
low tide at 6:00 a. m. and 6:00 p. m., depth 18 ft
d.
high tide at 12:00 noon, depth 23 ft
low tide at 6:00 a. m., depth 5 ft
