Answer:
1.function 1 has a greater rate of change than function 2
3. Function 1 has a greater y-intercept than function 2
Step-by-step explanation:
Using the table we can find the slope using
m = (y2-y1)/ (x2-x1)
 m = (29-5)/ (8-0)
      = 24/8
     = 3
The rate of change for the table is 3
The y intercept is (0,5)   
Using the graph  (0,-1)  and (2,0)
m = (y2-y1)/ (x2-x1)
 m = (0--1)/ (2-0)
      = (0+1)/2
     = 1/2
The y intercept is (0,-1)
Since 3>1/2 , function 1 has a greater rate of change than function 2
Since 5>-1, function 1 has a greater y-intercept than function 2
 
        
                    
             
        
        
        
The length of the envelope is 6.3 inches
Step-by-step explanation:
Width of the envelope = 3 inches
Diagonal of the envelope = 7 inches
To find: 
The length of the envelope. 
Let the length of the envelope be 'l'
 We can use pythogoras theorem to calculate the length. 
l = √(49-9) 
l = √(40) 
l = 6.3 inches
The length of the envelope is 6.3 inches
