A flowchart is a representation of an algorithm
Answer:
the visibility persists as long as both A and B exist.
Explanation:
Global visibility basically means that the visibility persists as long as both A and B exist. In programming global visibility signifies that the variable/data in question is visible from any context of the code. Meaning that it can be accessed and manipulated from any part of the code, even from within a function or another document. This makes it very easy to use and structure accordingly.
I believe the answer is B spread sheet because i use spread sheets to make my life easier. I organize info in a spread sheet then it is really easy to find.

Most computers have three types of ports: serial, parallel, and USB. A serial port is a type of interface that connects a device to the system unit by transmitting data only one bit at a time. Serial ports usually connect devices that do not require fast data transmission rates, such as a mouse, keyboard, or modem.
Answer:
# Solve the quadratic equation ax**2 + bx + c = 0
# import complex math module
import cmath
a = 1
b = 5
c = 6
# calculate the discriminant
d = (b**2) - (4*a*c)
# find two solutions
sol1 = (-b-cmath.sqrt(d))/(2*a)
sol2 = (-b+cmath.sqrt(d))/(2*a)
print('The solution are {0} and {1}'.format(sol1,sol2))
Hope This Helps!!!
