*i'll give brainliest to whoever answers this correctly*

this is trigonometry, cosine law

For f(x) = 3x+1 and g(x) = x2 - 6, find (g/f)(x)

The average daily maximum temperature for laura’s hometown can be modeled by the function f(x)=4.5sin(πx/6)+11.8 , where f(x) is the temperature in °c and x is the month. x = 0 corresponds to january.what is the average daily maximum temperature in may? round to the nearest tenth of a degree if needed.use 3.14 for π .

Will mark brainliest, , and rate to the best ! wait for pics
