Answer: 
Step-by-step explanation:
 Some transformations for a function f(x) are shown below:
 If  , the function is translated up "k" units.
, the function is translated up "k" units.
 If  , the function is translated down "k" units.
, the function is translated down "k" units.
 If  , the function is reflected across the x-axis.
, the function is reflected across the x-axis.
 If  , the function is reflected across the y-axis.
, the function is reflected across the y-axis.
 Therefore, knowing those transformations and given the exponential parent function:
 
 If it is reflected across the y-axis and the it is  translated down 4 units, we can determine that the resulting function is:
 
 
        
             
        
        
        
84.5 inches         1 ft
---------------- * ---------------- = 7.0 ft (rounded to the nearest tenth)
         1              12 inches
        
             
        
        
        
This expression is already simplified. 
        
             
        
        
        
<span>Given:
xbar = 20 min 
standard deviation = 8 min
total sample = 240 
Required:
how many gym members are expected to spend 4 min and 36 min on a treadmill today
Solution:
sd</span>² = (∑(x - xbar)²) / N - 1
there are 42 gym members at 4 minutes and 200 gym members in 36 minutes.
        
             
        
        
        
Answer:

Step-by-step explanation:
We are to determine which of these expressions are equivalent to: 




Therefore, the two equivalent expressions are:
