NEED HELP ASAP! 1. For a particular area, the average temperature, y, in degrees Fahrenheit x days after January 1 is given by the function y=30sin(2π/365(x−89))+65. The average temperature of 45° occurs twice a year. Find the number of days after January 1 for each of these occurrences.

a. The average temperature is 45° 47 days January 1.

b. The average temperature is 45° both 50 days and 314 days after January 1

c. The average temperature is 45° both 47 days and 280 days after January 1.

d. The average temperature is 45° both 47 days and 314 days after January 1.

The average daily temperature, t, in degrees Fahrenheit for a city as a function of the month of the year, m, can be modeled by the equation ...

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0
