Answer:
Step-by-step explanation:
The point will be 2 on the x-axis and 5 on the y axis.
Since at time 0 (midnight) the tide is at the highest, the tide is modeled by a cosine function.
The amplitude is
a = (10.3 - 0.3) / 2 = 5
The period is 12 hours
b = 2π / 12 = π/6
The vertical shift is
10.3 - 5 = 5.3
The equation then is
y = 5 cos (π/6 t) + 5.3

Thats four to the power of two.
problem 1: x^2 + 4 = 0 , x^2 = -4 , this problem has no real solution because x = 2i which is an imaginary number
problem 2: x^2 +x -6 = 0 , (x + 3)(x - 2) =0 , x = 2 or x = -3
problem 3: x^2 -6x +7 =0 , (x^2 -6x +9) - 2 =0 , (x - 3)^2 = 2 , x-3 = √2 , x = 3+√2 or x - 3 = -√2 , x = 3 - √2
