Answer:
sin /4 * sin
/4 * sin /6 = 1/2 *(cos
/6 = 1/2 *(cos  /12 - cos 5
/12 - cos 5 /12)
/12)
Step-by-step explanation:
Formula:- sinX sinY = (1/2) [ cos (X - Y) - cos (X + Y) ]
sin(π/4)sin(π/6) 
 = (1/2)[cos(π/4 - π/6) - cos(π/4 + π/6)] 
 = (1/2)[cos(3π/12 - 2π/12) - cos(3π/12 + 2π/12)] 
 = (1/2)[cos(π/12) - cos(5π/12)]
 
        
             
        
        
        
Answer:

Explanation:

the graph is translated 3 units to the left and 2 units down.
vertex: (-3,-2) point: (-1,-6)









 
        
                    
             
        
        
        
The graph is not a direct variation because the line does not go through the origin; option C.
<h3>What is a direct variation?</h3>
A direct variation is a relationship between two or more quantities in which as one quantity increases, the other quantity also increases. Similarly, if the other quantity decreases, the other decreases as well.
For the graph of a direct variation, the line must pass through the origin.
Therefore, the graph does not represent a direct variation because the line does not go through the origin.
In conclusion, direct variation involves a corresponding increase or decrease in two related quantities.

Answer:
The true statement about Kendra's sample is:
b) Kendra's samples are precise but not accurate.
Step-by-step explanation:
a) Data and Calculations:
Average age of dogs currently alive = 4.8 years
Average ages of dogs in Kendra's sample
Week   Average Age (in years)
1                    3.7
2                   3.8
3                   4.2
4                   4.1
5                  3.9
6                  3.9
7                  4.0
Total         27.6
Mean = 3.9 (27.6/7)
b) Accuracy refers to how close Kendra's sample mean age of dogs is to the average age value as stated in the Modern Dog Magazine.  While the Magazine stated an average age of 4.8 years, Kendra's sample produced a mean of 3.9 years.  On the other hand, precision refers to how close Kendra's sample measurements are to each other.  With a mean of 3.9 years, the sample measurements are very close to each other.  Therefore, we can conclude that "Kendra's samples are precise but not accurate."
