The first person can be chosen in 4 different ways.
The second person can be chosen in 3 different ways.
The third person can be chosen in 2 ways
The last person can only be chosen in 1 way.
4 * 3 * 2 * 1
there are 24 different ways that this can be done.
There is only 1 correct order.
The answer is 1/24 ways. 1/24 = 0.04166666
 
        
             
        
        
        
Answer:
21.98
Step-by-step explanation:
first you think about the equation for perimeter. P=d(pi)
then you multiply your radius by 2 and that is 7 so you multiply 7 by pi (3.14) 
that is the number of feet. so then you multiply your number of feet by your cost per foot and you get 21.98
 
        
             
        
        
        
The sum of everything is 720 degrees, because of the six sides in this figure. 
We sum all angles and get 595
720 - 595 = 125
The answer is 125 degrees
 
        
             
        
        
        
Looking at the graph you can see that the domain of the function is:
 [0, 3.85]
 To find the range of the function, we must follow the following steps:
 Step 1)
 Evaluate for t = 0
 h (0) = - 4.87 (0) ^ 2 + 18.75 (0)
 h (0) = 0
 Step 2) 
 find the maximum of the function:
 h (t) = - 4.87t ^ 2 + 18.75t
 h '(t) = - 9.74 * t + 18.75
 -9.74 * t + 18.75 = 0
 t = 18.75 / 9.74
 t = 1.925051335
 We evaluate the function at its maximum point:
 h (1.925051335) = - 4.87 * (1.925051335) ^ 2 + 18.75 * (1.925051335)
 h (1.93) = 18.05
 The range of the function is:
 [0, 18.05]
 Answer:
 Domain: [0, 3.85]
 Range: [0, 18.05]
