The average high temperature during the hottest month in Beijing, China, is 72°F. The average high temperature during the coldest month in Beijing is 18°F. The function t = 27 cosine (StartFraction pi Over 6 EndFraction (m minus 6)) + 45, where m represents the number of months after January, models the temperature throughout the year in Beijing. During which month in the year would the temperature reach 55°F? August September November December

During the month of September.

Step-by-step explanation:

The temperature in Beijing, in m months after January, is given by the following equation:

In which m is the number of months after January.

During which month in the year would the temperature reach 55°F?

We have to find m for which: T(m) = 55. So

Applying the inverse cosine to both sides:

8.27 months after January

8.27 + 1 = 9.27, so during the month of September.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
