New York temperature. For any date, the average temperature in New York can be approximated by T ( x ) = 43.5 − 18.4 x + 8.57 x 2 − 0.996 x 3 + 0.0338 x 4 , where T represents the temperature in degrees Fahrenheit, x = 1 represents the middle of January, x = 2 represents the middle of February, and so on. (Source: Based on data from www.worldclimate.com. ) Compute the average temperature in New York over the whole year to the nearest degree.

The city of Oakland wishes to see if there is a relationship between the temperature and the amount of electricity used (in kilowatts)
An unusually wet spring has caused the size of a mosquito population in some city to increase by 8%
each day. If an estimated 240,000 mosquitoes are in the city on May 9, find how many mosquitoes will
inhabit the city on May 26. Use y=240.000(1.08) where x is number of days since May 9.
On May 26 there will be approximately
(Round to the nearest thousand as needed)
