Answer:
The portfolio should invest 48.94% in equity while 51.05% in the T-bills.
Explanation:
As the complete question is not given here ,the table of data is missing which is as attached herewith.
From the maximized equation of the utility function it is evident that

For the equity, here as
 is percentage of the equity which is to be calculated is percentage of the equity which is to be calculated
 is the Risk premium whose value as seen from the attached data for the period 1926-2015 is 8.30% is the Risk premium whose value as seen from the attached data for the period 1926-2015 is 8.30%
 is the risk aversion factor which is given as 4. is the risk aversion factor which is given as 4.
 is the standard deviation of the portfolio which from the data for the period 1926-2015 is 20.59 is the standard deviation of the portfolio which from the data for the period 1926-2015 is 20.59
By substituting values.

So the weight of equity is 48.94%.
Now the weight of T bills is given as 

So  the weight of T-bills is 51.05%.
The portfolio should invest 48.94% in equity while 51.05% in the T-bills.
 
        
             
        
        
        
Answer:
a
The speed is    
 
b 
 The distance is  
Explanation:
From the question we are told that 
      The speed of the banana is  
    The distance from my  location is   
  
      The time taken is  
The speed of the ice cream is 
           
substituting values 
         
         
The distance of separation between i and Valdimir is the same as the distance covered by the banana
    So  
            
 
substituting values 
         
          
 
       
 
        
             
        
        
        
Yes!
I think there are two ways you could go with this answer:
1) Acceleration is the change in velocity over time, it can be negative or positive. If you have an object that is already moving forwards in a straight line and give it a constant negative acceleration, it will slow down and then start going in reverse.
2)Velocity is a vector, meaning it has both magnitude and direction. In the example above, the acceleration is due to a change in magnitude, or speed (from +ve to -ve) but not a change in direction. Something that has constant speed but is changing direction is also accelerating (like something that is orbiting). You could use the earth as an example, which is constantly accelerating due to moving in a circle around the sun. At any time in the year you can say that in half a year's time the earth's direction will be reversed.
        
             
        
        
        
Answer:
714.285s
Explanation:
use relative velocity
8-4.5 = 3.5m/s
x = 2500m
2500/3.5 = 714.285s = 700s (with sig figs)
