Answer:
The average rate of change of Demand between 40 and 175 units sold is of -0.1045.
Step-by-step explanation:
Average rate of change:
The average rate of a function f(x) in an interval [a,b] is given by:

In this question:

What is the average rate of change of Demand between 40 and 175 units sold?
 . So
. So


So

The average rate of change of Demand between 40 and 175 units sold is of -0.1045.
 
        
             
        
        
        
You can solve by using Pythagoras theorem.
Let the longest side be c.
a^2 + b^2 = c^2
If this holds, it is a right angle. 
But, 3.5^2 + 4.5^2 is not equal to 5.5^2.
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
The absolute change in game length is ...
   (180 min) -(150 min) = 30 min . . . . change in game length
__
The relative change is expressed as a fraction of the original game length:
   (30 min)/(150 min) × 100% = 20% . . . . relative change in game length
 
        
             
        
        
        
Answer:
m<3 = 97
m<10 = 97
m<9 = 83
m<5 = 97
m<7 = 83
m<16 = 97
Step-by-step explanation:
m<3 = m<2 because of vertical angles
m<10 = m<2 because of corresponding angles
m<9 + 97 = 180
m<9 = 83
m<5 + 83 = 180
m<5 = 97
m<7 = m<6 because of vertical angles
m<16 = m<5 because of alternate exterior angles.
 
        
             
        
        
        
Answer:

Step-by-step explanation:
The submersible is diving at a down angle of 15° along the hypotenuse AC of triangle ABC.  
Its horizontal track along the surface AB is 1500 ft.

The submersible was already at a depth of 250 feet when it began the dive.
New depth = 250 + 402 = 652 ft
