Question 6 Assume the coldest day of the year in Portland Maine is on January 20th where the average daily temperature is 10°F and the hottest day has an average daily temperature of 82°F. (a) Use a sinuisoidal function to model the average daily temperature, A(t), in Portland, Maine t days after January 20th, assuming that there are 365 days in a year. (b) How many days after January 20th does the average daily temperature reach 28°F? (c) Assume the oil price to heat a home varies linearly with average daily temperature. If the oil price is $2.30 per gallon when the average daily temperature is 60°F and $3 per gallon when the temperature is 25°F, write a function O(A) which gives the price of oil in dollars per gallon for an average daily temperature A degrees Fahrenheit.
