Answer:
50 \sqrt[]{2} feet
Step-by-step explanation:
Given the vertices  (1, 5) and (11, 15) for the corners labeled with red stars, the diagonal of the square C will be the length of the line joining the two vertices.
Using the Distance Formula:
Since 1 Square Unit = 25 Square Feet
1 Unit =5 feet
Therefore, the length of the diagonal
 
        
                    
             
        
        
        
Answer:
f(x) = -5x + 4
Domain refers to the values of x that would result to  a defined value of y. Since the given f(x) is a linear function, then all the values of x would give a corresponding value of y. So, the domain of f(x)=-5x+4 are all real numbers.
Or, plot the given equation to check.
The graph of f(x)=-5x+4 is shown below.
Since the graph is a straight line and can be extended continuously on both ends,  this indicates that every values of x, there is a corresponding value of y.
Hence, the domain of the given function are all real numbers.Step-by-step explanation:
 
        
             
        
        
        
Answer:
 13 1/2
Step-by-step explanation:
Just multiply 3.5 and 4.75 
AKA
3 1/2 and 4 3/4
Change 1/2 into 2/4 so the denominators are the same
Multiply the numerators 2 and 3, you now have 6/4
3 × 4 = 12
6/4 is improper so, you need to simplify 
now you have 1 1/2
Now 12 + 1 1/2 = 13 1/12
 
        
             
        
        
        
Answer:
Step-by-step explanation:
     5x + 3 = 23 x=4
5. 4 = 3a – 14 a=6
6. 2y + 5 = 19 y=7
