Answer:
   39 cups
Step-by-step explanation:
If we assume that the 3.5 cups of concentrate make 3.5+3 = 6.5 cups of tea, we can use the proportion ...
   6.5/3.5 = x/21
to find the x cups of tea Ahab can make with 21 cups of concentrate.
Multiplying by 21, we get ...
   x = 21(6.5/3.5) = 39
Ahab can make 39 cups of tea.

Answer: 
Step-by-step explanation:
 A line that cuts a circle at two points is called "secant".
 There is a theorem known as "Intersecting Secant Theorem". This is the theorem you need to use to find the value of "d".
 According the Intersecting Secant Theorem:
 
 Having this expression, the next step is to solve for "d":
 Use Distributive property:
 
 Subtract 256 from both sides:
 
 
 Divide both sides by 16:
 
 The value of "d" rounded to the nearest tenth is:
 
 
        
             
        
        
        
Answer: the average rate of change  is 4.
Step-by-step explanation:
 The average rate of change  is the slope. Therefore, you must use the following formula for calculate the slope:
 
 As you can see in the table, when x=5, y=-2 and when x=9, y=14. Then the points you must substitute into the formula are:
 (5,-2) and (9,14)
 Then, you obtain:
