Answer:
Option b
Step-by-step explanation:
To represent this proportion using fractions, let the numerators be the number of waffles sold and denominator, the number of sugar cones.
Thus, the proportion that can be used to represent the cone sales is
14/6 = 7/3
 
        
                    
             
        
        
        
Answer:
   a)  No. t < 0 is not part of the useful domain of the function
   b) 2.0 seconds
Step-by-step explanation:
a) A graph of the function is shown below. It shows t-intercepts at t=-0.25 and t=2.0. We presume that t is measured forward from some event such as the ball being thrown or hit. The model's predicted ball location has no meaning prior to that event, when values of t are negative.

b) It is convenient to use a graphing calculator to find the t-intercepts. Or, the equation can be solved for h=0 any of several ways algebraically. One is by factoring.
   h = 0 = -16t² +28t +8 . . . . . . . . . . . . the ball hits the ground when h = 0
   0 = -4(4t² -7t -2) = -4(4t +1)(t -2)
This has t-intercepts where the factors are zero, at t=-1/4 and t=2. 
The ball will hit the ground after 2 seconds.
