1. Using floating-point numbers can lead to arithmetic errors because floating-point numbers

a.	require the use of exponents
b.	are approximate values
c.	can’t be used in expressions with integers
d.	usually don’t have enough significant digits

ANS:  

2. Which of the following will produce the same result as this code?

import math as m

area = m.pi * radius**2

a.	area = m.pi * pow(radius)
b.	area = m.pi * m.pow(radius)
c.	area = m.pi * pow(radius, 2))
d.	area = m.pi * m.pow(radius, 2)

ANS:  

3. What will be displayed when this code is executed?

name = "Name"

ID = "ID"

print("{:10} {:>5}".format(name, ID))

print("{:10} {:7d}".format("Liz", 234))

print("{:10} {:7d}".format("Mike", 23456))

a.	Name          ID        Liz            234        Mike         23456	c.	Name      ID Liz            234 Mike         23456
b.	Name          ID Liz            234 Mike         23456	d.	Name         ID Liz          234 Mike         23456

ANS:  

Answer 1

1.
are approximate values

2.
area = m.pi * m.pow(radius, 2)

3
Name          ID
Liz            234
Mike         23456
