Answer:
Step-by-step explanation:
circumference  = 2* pi * radius = 1 
-> radius = 0.1592 mile 
-
> diameter = 2* radius = 0.31847 mile
 
        
             
        
        
        
Answer:
for this you should use photomath all you do is take a picture of each problem and put the answer down 
 
        
                    
             
        
        
        
This is a linear function, of the kind y = mx + b
where x is the number of visit,  b is the weight when x = 0, and m is the predicted change of weight for every visit.
m = - 4 ounces / visit, which must be converted to pounds (the negative sign indicates that the change is a decrease)
1 lb = 16 ounces = 4 ounces = 0.25 lb
Then m = - 0.25 lb / visit.
Now, for x = 1, y = 126 => 126 = - 0.25(1) + b => b = 126 + 0.25 = 126.25
Then the function is y = 126.25 - 0.25x
Now round to the nearest tenth:
y = 126.3 - 0.3x 
Answer: y = 126.3 - 0.3x
 
        
             
        
        
        
Answer:
 The answer is x=5 and x=−5
x² - 25 = 0
(x-5)(x+5)=0
x²-5x+5x-25=0
x-5=0 x+5=0
x=5 or x=-5
