Answer:
28
Step-by-step explanation:
28 = 7 x 4
So, 
7 is a factor of 28.
 
        
             
        
        
        
Just add the two bases plus the lateral area. so it would be 706.5+706.5+471.
        
                    
             
        
        
        
Answer:
The remnant of an estate that the grantor holds after he's granted a life estate to another person if the estate will return to the grantor, is called D) Reversion
Step-by-step explanation:
The correct answer is D) Reversion because, according to the Real Estate definitions, reversionary interest refers to future interest that reverts to a grantor, reversionary right refers to the return of the rights of the possession and quiet enjoyment to the lessor at the expiration of a lease and remainder estate refers to the remnant of an estate that has been conveyed to take effect and be enjoyed after the termination of a prior estate.
 
        
             
        
        
        
Answer: Answer for figure one is origin (0,0) 
Answer for figure two is (2,4) /
Step-by-step explanation:
a) Here we can see that given graph is the equation of cubic function which is 
f(-x) = -f(x) that is given function is odd then rotational symmetry point is origin always ,therefore point of rotational symmetry is origin (0,0) 
b) The rotational symmetry of  an ellipse is 180 degrees about the center  of  the ellipse . 
And here the center of given ellipse is  (2,4) ,therefore its rotational  symmetry is about (2,4) That is if we rotate the given ellipse 180 degrees about (2,4) it will be at its original position.
