Question

one spring day, serenity noted the time of day and the temperature, in degrees fahrenheit. her findings are as follows: at 6 a.m., the temperature was 50°f. for the next 5 hours, the temperature rose 1° per hour. for the next 4 hours, it rose 3° per hour. the temperature then stayed steady until 6 p.m. for the next 4 hours, the temperature dropped 3° per hour. the temperature then dropped steadily until the temperature was 54° at midnight. on the set of axes below, graph serenitys data. click twice to plot a segment. click a segment to delete it.

Explanation:

Step1: Calculate temperature from 6 a.m. - 11 a.m.

Starting at 50°F and rising 1°F per hour for 5 hours. The temperature at 11 a.m. is $50 + 1\times5=55^{\circ}F$.

Step2: Calculate temperature from 11 a.m. - 3 p.m.

Rising 3°F per hour for 4 hours. The temperature at 3 p.m. is $55+3\times4 = 67^{\circ}F$.

Step3: Note temperature from 3 p.m. - 6 p.m.

Stays steady at 67°F.

Step4: Calculate temperature from 6 p.m. - 10 p.m.

Dropping 3°F per hour for 4 hours. The temperature at 10 p.m. is $67 - 3\times4=55^{\circ}F$.

Step5: Analyze drop from 10 p.m. - midnight

Drops from 55°F to 54°F in 2 hours.

Answer:

Plot the following points and connect them with line - segments: (6 a.m., 50), (11 a.m., 55), (3 p.m., 67), (6 p.m., 67), (10 p.m., 55), (midnight, 54).
