Answer:

Step-by-step explanation:
Given equation can be  re written as 
 ............(i)
............(i)
Now it is given that y(π/2) = 2e
Applying value in (i) we get
ln(2e) = sin(π/2) + c
=> ln(2) + ln(e) = 1+c
=> ln(2) + 1 = 1 + c
=> c = ln(2)
Thus equation (i) becomes
ln(y) = sin(x) + ln(2)
ln(y) - ln(2) = sin(x)
ln(y/2) = sin(x)

 
        
             
        
        
        
Answer:
2x + 3y = 6
Step-by-step explanation:
obtain the equation in slope- intercept form
y = mx + c ( m is the slope and c the y-intercept )
here m = -  and c = 2
 and c = 2
y = -  x + 2 ← in slope-intercept form
 x + 2 ← in slope-intercept form
multiply all terms by 3 to eliminate the fraction
3y = - 2x + 6 ( add 2x to both sides )
2x + 3y = 6 ← in standard form
 
        
             
        
        
        
She regrouped the numbers instead of multiplying like 8b(2b-r) -4r(2b-r).
        
                    
             
        
        
        
to find the geometric mean, multiply them together, then take the square root
3*147
441
sqrt(441)
21
The geometric mean is 21
 
        
                    
             
        
        
        
Answer: 7
Step-by-step explanation:
C = 9
B = 6
Wherever you see a c, you put a 9. Wherever you see a b, you put a 6. If there is already a number in front of the B, multiply it by 6
