The tidal variation in Desolation Sound on the west coast of Canada is roughly 4 meters. That is, the difference beween water depth at high tide and at low tide is 4 meters, with successive high tides occurring 12.5 hours apart. Suppose that at Refuge Cove in Desolation Sound, the depth of water in meters is given by D(t) = D0 + Acos B(t - t0)

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

its a trick question

step-by-step explanation:

dogs love water, just turn on the hose and it will run in circles chasing the water all day : )

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
