Is the data set approximately periodic? If so, what are its period and amplitude? Determine if the data set is periodic, and if so, identify its period and amplitude.

A. not periodic
B. periodic with a period of 4 and an amplitude of about 20
C. periodic with a period of 4 and an amplitude of about 25
D. periodic with a period of 5 and an amplitude of about 25

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)
