Answer:
Amplitude. 
Step-by-step explanation:
Loudness of a sound wave is proportional to its amplitude of vibration. 
 
        
             
        
        
        
Value of n is greater than (-2) and less than or equal to 3. 
n = {-1,0,1,2 3}
3x +5 > 16
Subtract 5 from both sides 
3x > 16 - 5
3x > 11
x > 11/3
x> 3.67
X= 4 is the smallest value
        
                    
             
        
        
        
Answer:
The perimeter of triangle PQR is 17 ft
Step-by-step explanation:
Consider the triangles PQR and STU
1. PQ ≅ ST = 4 ft (Given)
2. ∠PQR ≅ ∠STU  (Given)
3. QR ≅ TU = 6 ft (Given)
Therefore, the two triangles are congruent by SAS postulate.
Now, from CPCTE, PR = SU. Therefore,

Now, side PR is given by plugging in 3 for 'y'.
PR = 3(3) - 2 = 9 - 2 = 7 ft
Now, perimeter of a triangle PQR is the sum of all of its sides.
Therefore, Perimeter = PQ + QR + PR
                                    = (4 + 6 + 7) ft 
                                    = 17 ft
Hence, the perimeter of triangle PQR is 17 ft.
