Answer:
1. x = -7
2. x = 6/13
3. x = 7/12
Step-by-step explanation:
1. x = 21 / -3
x = -7
2. 13x = 6
x = 6 / 13
x = 6/13
3. -12x = -7
x = -7 / -12

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.
