Antonio's toy boat is bobbing in the water under a dock. The vertical distance H (in cm) between the dock and
the top of the boat's mastt seconds after its first peak is modeled by the following function. Here, t is entered in
radians.
H(t) = 5 cos(2pi/3)t)-35.5
How long does it take the toy boat to bob down from its peak to a height of -35 cm?
Round your final answer to the nearest tenth of a second.

The equation of a circle is (x + 4)2 + (y + 6)2 = 16. determine the length of the radius. 10 4 16 8 my flower basket delivers flowers within a 20 mile radius of their store. if this area is represented graphically, with my flower basket located at (5, 2), what is the equation that represents the delivery area? (x - 2)2 + (y - 5)2 = 20 (x - 5)2 + (y - 2)2 = 20 (x + 5)2 + (y + 2)2 = 400 (x - 5)2 + (y - 2)2 = 400

What is the order of these fractions from least to greatest 2/3 7/10 5/8 65/100
