Answer: false
Step-by-step explanation:
If f and g are increasing on I, this implies that f' > 0 on I and g' > 0 on I. That is both f' and g' have a positive slope. However,
Using product rule;
 (fg)' = fd(g) + gd(f)
(fg)' = f * g' + f' * g
 
and although it is given that g' and f' are both positive we don't have any information about the sign of the values of the functions themselves(f and g). Therefore, if at least one of the functions has negative values there is the possibility that the derivative of the product will be negative. For example;
 
f = x, g = 5x on I = (-5, -2)
f' = 1 and g' =5 both greater than 0
f and g are both lines with positive slopes therefore they are increasing, but f * g = 5x^2 is decreasing on I.
 
        
             
        
        
        
D. Tanisha is 6, and Bess is 12
        
                    
             
        
        
        
0.06 or you can just put 6.
 Basically, you have to multiply 30% x 20.
 Glad I could help☺️
        
                    
             
        
        
        
Each pretzel is 4.5 $
1.50 • 5 = 7.5
7.5 - 30 = 22.5
22.5 / 5 = 4.5
so in conclusion, those are some expensive a** pretzels.
