Carbon dioxide particles in our atmosphere trap heat and raise the planet’s temperature. Even if all greenhouse-gas emissions miraculously ended today, the planet would continue to warm through the rest of the century because of the amount of carbon we have already added to the atmosphere. Carbon dioxide accounts for about half of global warming. The function y = 2.5 sin 2 π x + 0.0216 x 2 + 0.654 x + 316 models carbon dioxide concentration, y , in parts per million, where x = 0 represents January 1960; x = 1 12 , February 1960: x = 2 12 March 1960; … , x = 1 , January 1961; x = 13 12 , February 1961: and so on. Use a graphing utility to graph the function in a [30, 48, 5] by [310, 420, 5] viewing rectangle. Describe what the graph reveals about carbon dioxide concentration from 1990 through 2008.

The population of arctic foxes in Yukon can be modelled by the following equation:
P = 400 cos(30t - 180) + 1100
Where 't' represents the number of years since 1992.

What was the population of arctic foxes in Yukon in 1992?
What are the maximum and minimum number of arctic foxes?
Sketch a graph that represents how the population of artic foxes changes over time (since 1992).
What will be the population of arctic foxes in 2030?
When was the first time the population of arctic foxes reached 1300 (since 1992)?
Each time your heart beats, your blood pressure first increases and then decreases as the heart rests between beats. The maximum and minimum blood pressures are called the systolic and diastolic pressures, respectively. Your blood pressure reading is written as systolic/diastolic. A reading of 120/80 is considered normal.A certain person's blood pressure is modeled by the function
p(t) = 125 + 25 sin(150(pi)t)
where p(t) is the pressure in mmHg (millimeters of mercury), at time t measured in minutes.
(a) Find the period of p. min(b) Find the number of heartbeats per minute. heartbeats per minute
