Answer:
c. your friend can hash all possible options and discover your secret.
Explanation:
SHA-256 is a set of hash functions that was designed by the NSA. SHA-2 is considered an upgrade on the set that was its predecessor, SHA-1. A hash is a mathematical function that condenses data in a process of one-way encryption. SHA-256 creates hash algoritms that are considered irreversible and unique. However, one of the properties of hashing algorithms is determinism, which means that any computer in the world would be able to compute a particular hash and get the same answer.
Answer is A. The data has been filtered
The funnel in Excel lets you know that there is a filter in place on the columns. It is a filter icon. By default, any filtered column in Excel gets a little funnel icon on the top row as shown in the image attached. Once this funnel symbols is clicked, it gives you options to filter using several criteria.
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
