(29) A weight hanging on a spring will oscillate up and down about its equilibrium position after it's pulled down and released. This is an example of simple hormonic motion. This motion would continue forever if there wasn't any friction or air resistance. Simple harmonic motion can be described with the function
Where A is the amplitude, t is the time in seconds, m is the mass and k is a constant particular to that spring. If a spring is measured in centimeters and the weight in grams, then what are the amplitude and mass if
Amplitude: _____cm.
Mass: ______ g.

(36) Atmospheric Temperature. The average daily temperature in Peoria, Illinois, can be approximated by the equation 
where x is the number of days since December 31 of the previous year (Ex: January 1, x = 1; Mar 1, x = 60), and T is in degrees Fahrenheit. What is the expected temperature on July 4th, assuming it is not a leap year? Round your answer to one decimal place.
