An equation for water level in june for pensacola as a function of time (t) is f(t) = 5 cos pi/6 t + 7.
Which equation of cos show period amplitude ?
The equation given below show aplitude and period

where A = amplitude,
b = 2 pi/Period,
Period = 12 hrs,
c = midline,
x = t and y = f(t)
We have to find the amplitude
<h3>What is the formula for the amplitude?</h3>





Therefore, the an equation for water level in june for pensacola as a function of time (t)

Answer:
47.5
Step-by-step explanation:
19÷2=9.5x5=47.5
-3x + 4 > 5
-3x > 5 - 4
-3x > 1
x < 1/-3
x < -1/3
