Can you add the picture ?? If you don’t mind?? It helps me Answer better
Answer:
cos K = 12/13
Step-by-step explanation:
cos theta = opposite side/ hypotenuse for a right triangle
cos K = 12/13
12 2/6 is a mixed number. Though, it can be simplified to 12 1/3
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
