ANSWER
The other zero is 

EXPLANATION
The axis of symmetry serves as the midpoint of the two zeroes.
We were given that the axis of symmetry of the quadratic equation is 

We were also given that, one of the zeroes of the quadratic equation is 

Let the other zero of the quadratic equation be 

,then, we apply the midpoint formula to find the value of 

Since it is the x-values of the intercepts that gives the solution, we use only the x-value part of the midpoint formula which is given by,

We substitute to obtain,

We multiply through by 2 to get,

This implies that,

 
 
        
        
        
Answer:
6.30
Step-by-step explanation:
Ivanka’s ribbon = 4.5 inches long 
Michal’s ribbon is 3 1/2 times ivanka’s 
Therefore, 
Michal’s = 3 1/2 x 4.5
 = 7/5 x 4.5 
 = 31.5/5
 = 6.3 = 6.30 to the nearest hundredth
