Answer:
Explanation:
Transitive dependency
In this case, we have three fields, where field 2 depends on field 1, and field three depends on field 2.
For example:
Date of birth --> age --> vote
Partial dependency
It is a partial functional dependency if the removal of any attribute Y from X, and the dependency always is valid
For example:
Course and student these tables have a partial dependency, but if we have the field registration date, this date will depend on the course and student completely, we must create another table with the field registration date to remove this complete dependency.
If we remove or update the table registration date, neither course nor student must not change.
Answer:
#program in python.
#variables
slice_area=14.125
pi=3.14159
#read diameter
d=int(input("Enter diameter of pizza:"))
#area of pizza
area=pi*(d/2)*(d/2)
#number of slice
no_slice=int(area/slice_area)
#print slice
print("total silce are:",no_slice)
Explanation:
Declare and initialize a variable "slice_area" with 14.125 which is the area of a pizza slice.Initialize a variable "pi" with 3.14159.Then read the diameter of pizza.Find the area of pizza as "area=pi *d/2*d/2".Divide the total area with area of pizza slice.This will be the number of slice.
Output:
Enter diameter of pizza:20
total silce are: 22
