the height of the water H in feet at a boat dock t hours after 6 a.m. is given by H=10+sin pi/4 t. what is the height of the water at 10 a.m. ?
--------------
t = 10-6 = 4
h = 10 + sin(pi*t/4) = 10 + sin(pi)
h = 10 feet
Answer by rothauserc(4718) (Show Source): You can put this solution on YOUR website!
H = 10 + sin((pi/4)*t)
t = 10 - 6 = 4
H = 10 + sin((pi/4)*4)
H = 10 + sin(45*4)
H = 10 + 0 = 10
answer is d.
