The graph shows that at 100 feet the line is at its highest point.
 
        
             
        
        
        
The third one down 
Because the best line of fit is a line that goes between the plotted points and it HAS to be a straight line and most of the points close to the line
        
             
        
        
        
Answer: 475.59 meters .
Step-by-step explanation:
 The correct equation is the following: 
  
 
 For this exercise you need to use the Quadratic formula:
 
 In this case you can identify that the values of "a", "b" and "c" are:
 
 Now you must substitute these values into the Quadratic formula and then evaluate. You get:
 
 Choose the positive one and round it to the nearest hundreth:
 
 
        
             
        
        
        
   
The area of a rectangle is:
A =  length × width
A rectangular television screen has an area:
A = w² + 2w inches²
width = w
length = A / width  = (w² + 2w) / w = w(w + 2) / w = <u>w + 2</u>
Ansver:
<h2><u>
length = w + 2</u></h2><h2><u>
</u></h2><h2><u>
</u></h2>
 
        
             
        
        
        
X^8 = ()^2
x^8 = (x^4)^2
x^8 = x^8
inside the parethesis is x^4
hope this helps
