Answer:
<u>18 waves</u> hit the beach in 49 s.
Step-by-step explanation:
Given:
The frequency of the waves that were coming into the beach is 0.367347 Hz.
Now, to find the number of waves that hit the beach in 49 s.
Let the number of waves be 
The frequency of waves (
) = 0.367347 Hz.
The time it takes to hit the beach (
) = 49 s.
Now, we put formula to get the number of waves:

<u><em>The number of waves = 18.</em></u>
Therefore, 18 waves hit the beach in 49 s.
Given:
square shape
Perimeter 28 feet
Find its area
A square has 4 equal sides, so perimeter is 4a
Perimeter = 4a
28 ft = 4 a
28 ft / 4 = a
7 = a
One side of the the square is 7 ft.
Area of a square is the measure of one side raised to the power of 2.
A = a²
A = (7 ft)²
A = 49 ft²
Given the function, <em>f(x) = 3x + 6,</em> we can solve for f(a), f(a + h) and
by substituting their values into f(x) = 3x + 6. We will have the following:

<em><u>Given:</u></em>
<em>We are told to find:</em>
- f(a)
- f(a + h), and

1. <em><u>Find f(a):</u></em>
- Substitute x = a into f(x) = 3x + 6
f(a) = 3(a) + 6
f(a) = 3a + 6
<em>2. Find f(a + h):</em>
- Substitute x = a + h into f(x) = 3x + 6
f(a + h) = 3(a + h) + 6
f(a + h) = 3a + 3h + 6
<em>3. Find </em>
<em>:</em>
- Plug in the values of f(a + h) and f(a) into

Thus:


Therefore, given the function, <em>f(x) = 3x + 6,</em> we can solve for f(a), f(a + h) and
by substituting their values into f(x) = 3x + 6. We will have the following:
