Consider the graph of the function f(x) = 2(x + 3)2 + 2. Over which interval is the graph decreasing? (–∞, –3) (–∞, 2) (–3, ∞) (2, ∞)
Answers
Answer:
The interval over which the graph is decreasing is;
(-∞, -3)
Explanation:
The given function is f(x) = 2·(x + 3)² + 2
By expanding the function, we have;
2·x² + 12·x + 20
From the characteristics of a quadratic equation, we have;
The shape of a quadratic equation = A parabola
The coefficient of x² = +2 (positive), therefore the parabola opens up
The parabola has a minimum point
Points to the left of the minimum point are decreasing
The minimum point is obtained as the x-coordinate value when f'(x) = 0
∴ f'(x) = d(2·x² + 12·x + 20)/dx = 4·x + 12
At the minimum point, f'(x) = 4·x + 12 = 0
∴ x = -12/4 = -3
Therefore;
The graph is decreasing over the interval from -infinity (-∞) to -3 which is (-∞, -3)
Please find attached the graph of the function created with Microsoft Excel
The graph is decreasing over the interval (-∞, -3).

Explain why the program did not print "clap", and how to fix it.
#takes number of fingers and recommends a thoughtful response
fingers = 10
if fingers >= 2:
print("whistle")
elif fingers >= 4:
print("snap")
elif fingers >= 10:
print("clap")
else:
input("are you human?")
Answers
Answer:
Because you're using "elif".
If I were to have this code:
if *blank*:
*action 1*
elif *blank*:
*action 2*
If and elif is basically saying "one or the other". Since 10 is >= 2, it prints out only whistle. Instead of elif, you were to replace them all with "if", it would print out:
whistle
snap
clap

When is the following expression true? (2 points)
!(!a || b) || (!a && b)
1) If and only if a and b have different values
2) If and only if a and b have the same value
3)
If and only if both a and b are true
4) If and only if both a and b are false
5) The expression is never true
Answers
Answer:
1) If and only if a and b have different values
Explanation:
Given
Expression: !(!a || b) || (!a && b)
Required
When is it true?
The expression is true when the values a and b are different and the proof is as follows.
(1) Assume that: a = true and b = false
!(!a || b) || (!a && b)
= !(!true || false) || (!true && false)
!true = false, so the expression becomes:
= !(false|| false) || (false && false)
In boolean, false|| false = false and false && false = false. So, we have:
= !(false) || (false)
!(false) = true, so, the expression becomes:
= true || (false)
Lastly, true || false = true
(2) Assume that: a = false and b = true
!(!a || b) || (!a && b)
= !(!false|| true) || (!false && true)
!false = true, so the expression becomes:
= !(true|| true) || (true && true)
In boolean, true|| true = true and true && true = true. So, we have:
= !(true) || (true)
!(true) = false, so, the expression becomes:
= false|| true
Lastly, false || true = true
This expression is false if a and b have the same value

Vector graphics have the unique advantage over raster graphics in that the points, lines, and curves may be scaled up or down to any resolution with no aliasing. The points determine the direction of the vector path; each path may have various properties including values for stroke color, shape, curve, thickness, and fill.

Create an array of size 10 and name RandArray populate the RandArray with random integer from 1 to 20. Every element in the RandArray must be changed as follows: If the value of the element is less than the array index, the element must be replaced with the index plus 10. If the value of the element is equal to the index, the element must be doubled. If the value of the element is greater than the index, the element must be replaced by the index squared. Print the original number and the changed number of the RandArray
Answers
Answer:
int[]RandArray = new RandArray[10];
for(int x =0; x< RandArray.length;x++){
RandArray[x] = random.nextInt(10 - 1 + 1) + 1;
}
for(int x =0; x< RandArray.length;x++){
int og = RandArray[x];
if(RandArray[x]<x){
RandArray[x] = x + 10;
}
else if(RandArray[x] == x){
RandArray[x] =RandArray[x] * 2;
}
else if(RandArray[x] > x){
RandArray[x] =Math.pow(x,2);
}
System.out.println("Original: " + og +"New: "+ " RandArray[x])

Explanation:
Following are the python program for calculating the array values by using the random array function:
Python Program:
import random as R#import package of random
R1 = R.sample(range(1, 20), 10) #Generating 10 random numbers from 1 to 20
RandArray = R1.copy() #Copying the elements of R1 in to RandArray
print("Original Array: ",RandArray)#defining the print method that prints RandArray value
for e in range(len(RandArray)):#defining a loop that calculates
if(RandArray[e] < e):#defining if block that checks index of list that stores random number
RandArray[e] = e+10#adding 10 in numbers
elif(RandArray[e] == e):#defining if block that checks index of list that stores random number
RandArray[e] = e*2#multiplying by 2 in number
elif(RandArray[e] > e):#defining if block that checks index of list that stores random number
RandArray[e] = e**2#calculating the square value of RandArray
print("Changed Array: ",RandArray)#print RandArray value
for i in range(10):#defining loop that prints Array value
print("Original Number:",R1[i], "Changed Number:",RandArray[i])#print RandArray value
Output:

Moving your Sprite from right to left is considered the X coordinate?
Question 12 options:
True
False
Answers
Answer:
True.
Explanation:
X coordinates run from left to right, while Y runs from the top to the bottom.
To help you remember it, think of this:
A plane takes off and lands at the X coordinates and can choose whichever way it wants to take off from: left or right. Until the plane takes off, your Y coordinate is at 0. Once it's in the air, Y coordinates jumps in with our X and the plane can go up and up as it pleases (of course, there are limits) until it lands at the next airport.
Please note that x and y coordinates are always there, but in some cases they will stay at 0,0.

Change each mention of dog to puppy. Change each mention of taco to burrito. Print the new sentence. Capitalization matters! For example, if theres a mention of Dog (note where the capital letter is), it should be changed to Puppy (note where the capital letter is). You will only need to look for mentions of dog, Dog, taco, and Taco. The plural forms are allowed but the final output for dog / Dog will not be grammatically correct, and this is ok.
