Given:
The sine function is:

To find:
The frequency of the graph of given function.
Solution:
If a sine function is defined as:

Then, the frequency of the sine function is:

We have,

Here,  . So, the frequency of the given function is:
. So, the frequency of the given function is:


Therefore, the correct option is D.
 
        
             
        
        
        
Step-by-step explanation:

Angle C must = [180 - 73 - 57 ] = [180 - 130] = 50°
And using rhw Law if Sines, we have.....
AB/sin C = AC/sin B → 24/sin(50) = AC/sin(73) → AC = 24*sin(73)/sin(50) = about 29.96 in
 
        
             
        
        
        
45% if you need further explanation i can give it to you
        
                    
             
        
        
        
I’d say the second one, the fourth one and the fifth one. 
Hope it works :)

Answer:
-  0 < x < 4
-  (- ∞ < x < 0) ∪ (4 < x < ∞)
- x ∈ {0, 4}
Step-by-step explanation:
1. The solution is the set of x-values for which the graph is above the x-axis, where y = 0. Those x-values are in the interval (0, 4).
__
2. The solution is the set of x-values for which the graph is below the x-axis. Those x-values are in either of the two intervals (-∞, 0) or (4, ∞).
__
3. The x-intercepts of the graph are x=0 or x=4.
