I am in math urgent care. Please help. The water level in a harbor is described by the function y = 7 cosine (pi x/6) + 25, where y represents the water level measured in feet, and x represents the number of hours since high tide. After approximately how many hours is the water expected to reach a depth of 28 feet the second time? Round to the nearest hour.

1 hour
2 hours
10 hours
12 hours

City l has a temperature of −3 °f. city m has a temperature of −7 °f. use the number line shown to answer the questions: number line from negative 8 to positive 8 in increments of 1 is shown. part a: write an inequality to compare the temperatures of the two cities. (3 points) part b: explain what the inequality means in relation to the positions of these numbers on the number line. (4 points) part c: use the number line to explain which city is warmer. (3 points)
