The height of the tide after eight hours is 16 feet.
<h3>How to illustrate the function?</h3>
From the information given, the function is given as 5cos (π/4)t + 11.
In this case, the time is given as eight hours. This will be:
f(8) = 5 × cos (π/4) × 8 + 11
f(8) = 5 × cos(2π) + 11
= (5 × 0.999) + 11
= 16 feet
The height is 16 feet.

1.15/3 = 20 minutes worth = 0.383
60 minutes+20 minutes=80 minutes = 1.15+0.383=1.53
1.5/3 = 0.5 = 20 minutes
60 minutes+20 minutes=80 minutes =1.5+0.5=2
2-1.53=0.47 therefore it is 0.47 minutes quicker with Model A
