Answer:
The dimensions of the rectangle = 60ft by 107ft
Where 60 ft = Width of the playing field
107ft = Length of the playing field
Step-by-step explanation:
A playing field is Rectangular is shape, hence,
The formula for Perimeter of a rectangle = 2(L + W)
P = 334 ft
L = 47 + W
W = W
Hence we input these values in the formula and we have:
334 = 2(47 + W + W)
334 = 2(47 + 2W)
334 = 94 + 4W
334 - 94 = 4W
240 = 4W
W = 240/4
W = 60
There fore, the width of this playing field = 60 ft
The length of this rectangle is calculated as:
47 + W
47 + 60
= 107 ft
The length of this playing field = 107ft
Therefore the dimensions of the rectangle = 60ft by 107ft
 
        
             
        
        
        
The Last on = 45x^2 - 2x - 8
Reason being is because you would group and multiple:
(9x - 4) • (5x +2)
        
             
        
        
        
₇P₅ is a permutation. you can find this setting in the statistics menu of your scientific calculator (i think).
If you don't have a scientific calculator, you can use the following formula:
nPr = 
₇P₅  = 
      = 
      = 
      = 7 * 6 * 5 * 4 * 3 
     = 2520

Answer:
It's C.
Step-by-step explanation:
Any value of x must have a bigger negative number than 5. In this case, formally you say that all x values must be LESS than 5 only.
 
        
             
        
        
        
Answer:
You could use a piece wise function to simulate the speed someone is running at a given time in minutes. 
for  s = 9 mph
      s = 9 mph
for  s = 0 mph
     s = 0 mph
for  s = 6 mph
      s = 6 mph
