Answer:
 {-2, - 1, 0, 1} 
Step-by-step explanation:
The integer solutions will be {-2, - 1, 0, 1} 
 
        
                    
             
        
        
        
The answer would be 747.50! Because if you were wanting to decrease the price then you would multiply $299 by 40% So since you are wanting to add to the price then you would divide...Hope that makes since :)
        
                    
             
        
        
        
We have been that frequency (y) varies inversely with wavelength (x).
We know that two inversely proportional quantities are in form  , where a is inversely proportional to b and k is constant of variation.
, where a is inversely proportional to b and k is constant of variation.
Our required equation would be  .
.
To find frequency of blue light, we will substitute  and
 and  in our equation as:
 in our equation as:


Therefore, the frequency of blue light is 764.
 
        
             
        
        
        
Answer:
The measure of an interior angle of a regular 12-gon is 150°.
Hence, option 'C' is correct.                          
Step-by-step explanation:
We need to determine the measure of an interior angle of a regular 12-gon.
- We know that the number of sides in a regular 12-gon = n = 12
Thus,
Using the formula to determine the measure of an interior angle of a regular 12-gon is given by
(n - 2) × 180° = n × interior angle
substitute n = 12
(12 - 2) × 180 = 12 × interior angle
10 × 180 = 12 × interior angle
Interior angle = (10 × 180) / 12
                       = 1800 / 12
                       = 150°
Therefore, the measure of an interior angle of a regular 12-gon is 150°.
Hence, option 'C' is correct.
