<PRE><B>Question 866941</B>
The height of the water, H, in feet, at a boat dock t hours after 6 a.m. is given by H=8+6sin(pi/3)t. Find the height of the water at 9 a.m.
----------------------------
H(3) = 8+6*sin[(pi/3)*3]
----------------
H(3) = 8 + 6sin(pi)
====
H(3) = 8+6*0
----
H(3) = 8 ft.
Cheers,
Stan H.
