Question 1: The water level in a tank can be modeled by the function h(t)=4cos(+)+10, where t is the number of hours
since the water level is at its maximum height, h. How many hours pass between two consecutive times when
the water in the tank is at its maximum height?

Question 2: Point B has coordinates (3, -4) and lies on the circle whose equation is x + y = 25. If an angle is drawn in
standard position with its terminal ray extending through point B, what is the sine of the angle?
