The mean orbital radius r (in units of 10 5 km ) of a moon of Saturn can be modeled by the equation r = 1.93 t 2 / 3 , where t is the time in (Earth) days for the moon to complete one orbit about the planet. Use this model to estimate the instantaneous rate of change of r with respect to t when t = 0.602 day (the orbital period of Saturn’s moon Atlas).

A pendulum is release data point 5 meters to the right of its position at rest. Graph a cosine function that
represents the pendulum's horizontal displacement relative to its position at rest if it completes one back-and-forth
swing every π seconds.

On 31 January, 2009, during a heat wave in Mildura, Victoria, the maximum temperature recordedwas approximately 44 ◦C and the minimum overnight temperature recorded was approximately 26 ◦C.
(a) Using a sine function, write down an equation that models the temperature T (in ◦C) in Mildura on that day as a function of t (measured in hours since midnight). Explain how you determine each of the constants in your equation, and write down any assumptions you make.
