The temperature at the beach varies throughout the day. The temperatures vary according to the sinusoidal function:

A(t)= 19+6sin (\pi (t - \dfrac{1}{2}))

where t is the temperature (ºC) and A(t) is the time in hours past midnight.

null

What is the temperature as people arrive at the beach at 10 A.M. in \degree C?

The temperature in the desert is modeled by the function B(t)=\dfrac{35t(t-5)}{t^2+8t+16} + 17, where t is the temperature (°𝐶) and A(t) is the time in hours past midnight.

null

What is the maximum temperature in a single 24 hour day in \degree C? Round to the nearest tenth of a degree.

Ɛhia

At noon, it is hotter in the desert than at the beach.

Order the temperatures at each time from lowest to highest.

Temperature at the beach at noon
Temperature in the desert at 11 A.M.
Temperature in the desert at 8 A.M.
Temperature at the beach at 9 A.M.
Temperature in the desert at 5 P.M.
Temperature at the beach at 4:30 P.M.
