Answer:
Enlargement by a scale factor of 3 centre (1,0)
Step-by-step explanation:
The given function is

with
t = time, hours
f = temperature, °C
Because the maximum and minimum values for the Sine function are +1 and -1 respectively,
The maximum value of f = 33 - 20 = 13.
The minimum value of f = -33 - 20 = -53.
The period, T, is given by

Answer:
Maximum: 13°; Minimum: -53°; period: 4 hours
3 5/9, 4 8/9= 44/9 and 2/3=3/2 and when you add them it equals 96/27, and in simplest form it equals 3 5/9
