Answer:
ArrayList a contains [2, 3, 3, 3, 4, 5, 3, 2, 1]
Explanation:
Given
The removeValue method
Required
The content of ArrayList a, after the method is called
From the question, we understand that arraylist a is:
![a= [2, 3, 4, 3, 3, 4, 4, 5, 4, 3, 2, 1]](https://tex.z-dn.net/?f=a%3D%20%5B2%2C%203%2C%204%2C%203%2C%203%2C%204%2C%204%2C%205%2C%204%2C%203%2C%202%2C%201%5D)
The function fails when the value to be removed appear consecutively in the list.
4 appears in index 5 and 6 of the list. Only one of the 4's will be removed
So, the updated list will be: [2, 3, 3, 3, 4, 5, 3, 2, 1]
Answer:
Hello!
The statement is "if x and y are odd integers, then x + y is even"
and we want to prove it by contradiction.
Suppose that we have x and y odd numbers, and suppose that his addition is odd.
We know that an odd number can be writen as (2n +1) (and a even number can be written as 2n) where n is an integer number; then:
x = (2k + 1) and y = (2m + 1)
and x + y = j, where j is also a odd number, then j = (2h + 1)
then:
2k + 1 + 2m + 1 = 2h + 1
2(k + m) + 2 = 2h + 1
2(k + m) +1 = 2h
if k and m are integers, then k + m is also an integer, suppose that k + m = g
then 2g + 1 = 2h
this says that in odd number is equal to an even number, then we have a contradiction, and the addition of two odd numbers cant be an odd number.
The creator of the MyDoom virus is still unknown. This is known to be a worm that was said to have appeared in a from of a poorly sent e-mail, and a lot of people who originally were sent the e-mail did ignored it, thought it was a spam and they ignored it and as such, , it was said to have spread to infect about 500 thousand computers in the whole world.
<h3>What does MyDoom virus do?</h3>
The MyDoom virus was said to be the one that brought about a lot of loss in the whole globe.
The MyDoom is known to be an effective worm that was created to make zombies out of lots of thousands of computers.
Note that the Hackers are able hijacked terminal to wage a kind of denial of service (DoS) attack to any firm that they do identified.
The virus is known also as Novarg as it is a“worm,” sthat do pread by mass emailing.
Therefore, The creator of the MyDoom virus is still unknown.

Answer:
h = 8.588 m
Explanation:
Given:
Mass of hockey puck: m = 200 g = 0.2 K
g
Angle of incline: θ = 30º (with respect to horizontal)
Coefficient of static and kinetic friction between the puck and ramp:
μ
s = 0.4 and μk = 0.3
initial speed:
v = 3.5 m
/s
Let h be the vertical height reached by the puck, above the ground. This corresponds to a distance of
d = h
*sin 30º = 2
*h
along the incline. As the puck is moving, only kinetic friction comes into play as it climbs up the incline. Let N be the normal reaction exerted by the metal ramp on the ball. Then,
N = m*g
*cos θ = 0.2
*9.8
1*cos 30
º = 1.6991 N
Therefore, kinetic friction acting on the puck is:
F
k = μ
k
*N = 0.3
*1.6974 = 0.50974 N
From work energy theorem, the change in kinetic energy should equal the work done by friction and gravity. Therefore,
0.5* 0.2
*16² = 0.50974
*2h + 0.2*9.81*h
⇒ h = 8.588 m
