Let g(x) = cos(x/2) - 3x. Let f(x) = 2x + 5. What is g(f(x))?​

Answers

Answer 1

Answer:

f = 2

Explanation:

g(x) = cos(x/2) - 3x=w where w=-3.5 or -1 or -38.5

13– (13/2)-3*13=-3.5 (1st d value of g(x))

-1-(-1/2)-3*(-1)=-1 (the 2nd possible value)

g(x) = cos(x/2) - 3x=-1 where the first x=13 and the 2nd one=-1

where the first x=-1 and the 2nd one=-38.5 (the 3rd value)

g(x) = cos(x/2) - 3x)=0 where cos(x/2=-3.5

g(f(x)) = cos(f(x)/2) - 3 aka 0.5 f(x) = cos(2x+5 aka 7x) (x/2 - 3 =aka -1 );

(2x+5) = 7x by definition but the equation has to be set to 7 to find x)

(7x/2 -6x=0) -7 on both sides

x/2–6x=-7

x/2= 13

26/2=x

x=13 (these values are set up for 2x+5=7.

13-(-7)=-7

13-6+-1=-7

the 2nd x=-1

gfx=cos*2*x i.e cos*2*13 or cos*2*-1

cos*2*13=26

cos*2*(-1)=-1

cos=1

(cos*2*13)=the 1st gfx value=26 basically.

( cos*2*(-13)=-26 (the 2nd gfx value)

cos*2*(-1)=-`1 (the 3rd gfx value)

f=2

hope this helped!

Write a program that creates an integer array with 40 elements in it. Use a for loop to assign values to each element of the array so that each element has a value that is triple its index. For example, the element with index 0 should have a value of 0, the element with index 1 should have a value of 3, the element with index 2 should have a value of 6, and so on.

Answers

Answer:

public class Main

{

public static void main(String[] args) {

 int[] numbers = new int[40];

 for (int i=0; i<40; i++){

     numbers[i] = i * 3;

 }

 for (int i=0; i<40; i++){

     System.out.println(numbers[i]);

 }

}

}

Explanation:

*The code is in Java.

Initialize an integer array with size 40

Create a for loop that iterates 40 times. Inside the loop, set the number at index i as i*3

i = 0, numbers[0] = 0 * 3 = 0

i = 1, numbers[1] = 1 * 3 = 3

i = 2, numbers[2] = 2 * 3 = 6

.

.

i = 39, numbers[39] = 39 * 3 = 117

Create another for loop that iterates 40 times and prints the values in the numbers array

Write a function named minMax() that accepts three integers arguments from the keyboard and finds the smallest and largest integers. Include the function minMax() in a working program. Make sure your function is called from main().Test the function by passing various combinations of three integers to it.

Answers

Answer:

public class Main

{

public static void main(String[] args) {

 minMax(1, 2, 3);

 minMax(100, 25, 33);

 minMax(11, 222, 37);

}

public static void minMax(int n1, int n2, int n3){

    int max, min;

    if(n1 >= n2 && n1 >= n3){

        max = n1;

    }

    else if(n2 >= n1 && n2 >= n3){

        max = n2;

    }

    else{

        min = n3;

    }

    System.out.println("The max is " + max + "\nThe min is " + min);    

}

}

Explanation:

*The code is in Java.

Create a function named minMax() that takes three integers, n1, n2 and n3

Inside the function:

Declare the min and max

Check if n1 is greater than or equal to n2 and n3. If it is set it as max. If not, check if n2 is greater than or equal to n1 and n3. If it is set it as max. Otherwise, set n3 as max

Check if n1 is smaller than or equal to n2 and n3. If it is set it as min. If not, check if n2 is smaller than or equal to n1 and n3. If it is set it as min. Otherwise, set n3 as min

Print the max and min

Explanation:

Analyzing the given code segment

In class Dance,

A method named dance was defined with an instance of two string variables/values

which are name and song

public Dance(String name, String s)

In the main of the program,

The first line creates an instance of Dance as dance1

dance1 is initialized with the following string values: "Tango","Hernandos Hideaway"

- The first string value "Tango" will be passed into the name variable of the Dance method

- The second string value "Hernandos Hideaway" will be passed into the song variable of the Dance method

Next, another instance of Dance is initialized as dance2

dance2 is initialized with the following string values: "Swing","Hound Dog"

- The first string value "Swing" will be passed into the name variable of the Dance method

- The second string value "Hound Dog" will be passed into the song variable of the Dance method

On line 3 of the main: System.out.println(dance1.toString());

The values of dance1, which are "Tango","Hernandos Hideaway" are printed

On line 4 of the main: System.out.println(dance2.toString());

The values of dance1, which are "Swing","Hound Dog" are printed

Hence, option d answers the question
