Z=1 eventually you get 15 divided by 15 giving you Z=1 it’s a long equation
        
                    
             
        
        
        
Answer:
-29.988 or if you round up -30
Step-by-step explanation:
1) Convert fractions to decimals   
     3.6 x (-8.33) = -29.988 
 
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
I'm sure you want your functions to appear as perfectly formed as possible so that others can help you.  f(x) = 4(2)x should be written with the " ^ " sign to denote exponentation:  f(x) = 4(2)^x
                                                                                       f(b) - f(a)
The formula for "average rate of change" is a.r.c. = --------------
                                                                                            b - a
                                     change in function value
This is equivalent to  ---------------------------------------
                                             change in x value
For Section A:  x changes from 1 to 2 and the function changes from 4(2)^1 to  4(2)^2:  8 to 16.  Thus, "change in function value" is 8 for a 1-unit change in x from 1 to 2.  Thus, in this Section, the a.r.c. is:
                  8
                ------ = 8 units    (Section A)
                   1
Section B:  x changes from 3 to 4, a net change of 1 unit:  f(x) changes from
4(2)^3 to 4(2)^4, or 32 to 256, a net change of 224 units.  Thus, the a.r.c. is
         224 units
       ----------------- = 224 units (Section B)
             1 unit
The a.r.c for Section B is 28 times greater than the a.r.c. for Section A.
This change in outcome is so great because the function f(x) is an exponential function; as x increases in unit steps, the function increases much faster (we say "exponentially").
 
        
             
        
        
        
Answer:
10 days. 
Step-by-step explanation:
8÷12 (because you can not divide people. 
.666 
take that and multiply it by 15
you will get 10
