Draw a diagram to illustrate the problem as shown in the figure below.
The minimum depth of 2.5 m occurs at 12:00 am and at 12:30 pm.
Therefore the period i0s T= 12.5 hours.
The maximum depth of 5.5 m occurs at 6:15 am and at 6:45 pm. Therefore the period of T = 12.5 hours is confirmed.
The double amplitude is 5.5 - 2.5 = 3 m, therefore the amplitude is a = 1.5 m.
The mean depth is k = (2.5 + 5.5)/2 = 4.0 m
The model for tide depth is
That is,
d = -1.5 cos(0.5027t) + 4
where
d = depth, m
t = time, hours
A plot of the function confirms that the model is correct.

Answer:
He have <u>15</u> action games and <u>24</u> sports games.
Step-by-step explanation:
Given:
Ryan has a mix of action and sports games for a total of 39 video games his action collection is three more than half his sports collection.
Now, to find the number of action games and sports games.
Let the sports games be
As, given his action collection is three more than half his sports collection.
Thus, the action games = .
Total number of video games = 39.
So, we set an equation to get the number of action games and sports games:
<em>Subtracting both sides by 3 we get:</em>
<em>Multiplying both sides by 2 we get:</em>
<em>Dividing both sides by 3 we get:</em>
<u>The sports games he have = 24.</u>
Now, to get the action games we substitute the value of :
=
=
=
<u>The action games he have = 15.</u>
Therefore, he have 15 action games and 24 sports games.
