"High tides at a beach occur at intervals of 12 h 25 min. Yesterday, high tide was measured at 5 ft above sea level and low tide was measured at 1 ft above sea level. What is the amplitude of a cosine function modeling the depth of the water in feet as a function of time in hours

Respuesta :

Answer:

2

Step-by-step explanation:

you have to subtract 5-1 = 4

then you do: 4/2=2

The amplitude of a cosine function modeling the depth of the water in feet as a function of time in hours is 2.

What is amplitude?

The largest amount of displacement of a particle on the medium from its rest position is referred to as the amplitude of a wave.

High tide is 5 ft

Low tide is 1 ft

Subtract the low tide to high tide

5 – 1 = 4

then divide it by 2

[tex]\dfrac{4}{2} = 2[/tex]

Thus, the amplitude of a cosine function is 2.
