Answer:
   (d)  -√((2+√2)/(2-√2))
Step-by-step explanation:
5π/8 is a 2nd-quadrant angle whose reference angle is greater than π/4. This means the tangent is negative with a magnitude greater than 1. The only reasonable choice is ...
   
_____
<em>Additional comment</em>
This simplifies to -(1+√2). Your calculator can verify the choice for you.
 
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
A grocery store has a 13%-off sale on all bread.
Let b represent the original price of a loaf of bread.
 This means that the amount by which the price of bread was reduced would be 
13/100 × b = 0.13 × b = 0.13b
The new price for the loaf of bread would be 
b - 0.13b
you decide to purchase 6 loaves of bread. The expression would be 
6(b - 0.13b)
Expanding the expression, it becomes
6b - 0.78b
 
        
             
        
        
        
Answer:
There is NO solution
Step-by-step explanation:
Considering 'y' be the number
Considering x be the smaller number
As 'y' is equal to twice a smaller number plus 3.
so

also
y is equal to twice the sum of the smaller number and 1.
so

so the system of equations become


solving







Therefore, there is NO solution.
 
        
             
        
        
        
190/5= rate per hour 38
38 (rate per hour)*48 (given hours)= 1824 quarts 
38(rate per hour)* 24 (hours in a day)= 912 quarts per day
or
1824(quarts made in two days (48 hours))/2=912 quarts per day
