Answer:

A. float()

Explanation:

(sorry i'm late :c, but please still mark me brainliest!)

A float is a floating-point number, which means it's a number that has a decimal point. It can be positive, negative, or 0.0.

Examples: 1.15, -2.25, 100.0, 0.0

Sketch f(x) = 5x2 - 20 labelling any intercepts.

Norma-Jean [14]

Answer:

The graph of the function is attached below.

The x-intercepts will be: (2, 0), (-2, 0)

The y-intercept will be: (-20, 0)

Explanation:

Given the function

$f\left(x\right)\:=\:5x^2-\:20$

As we know that the x-intercept(s) can be obtained by setting the value y=0

$y=\:5x^2-\:20$

switching sides

$5x^2-20=0$

Add 20 to both sides

$5x^2-20+20=0+20$

$5x^2=20$

Dividing both sides by 5

$\frac{5x^2}{5}=\frac{20}{5}$

$x^2=4$

$\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}$

$x=\sqrt{4},\:x=-\sqrt{4}$

$x=2,\:x=-2$

so the x-intercepts will be: (2, 0), (-2, 0)

we also know that the y-intercept(s) can obtained by setting the value x=0

$y=\:5(0)^2-\:20$

$y=0-20$

$y=-20$

so the y-intercept will be: (-20, 0)

From the attached figure, all the intercepts are labeled.

zlopas [31]

import java.util.Scanner;

public class U1_L5_Activity_One {

public static void main(String[] args) {

Scanner scan = new Scanner(System.in);

System.out.print("Please enter a two digit number: ");

int x = scan.nextInt();

System.out.println("Here are the digits:");

System.out.println(x/100);

System.out.println((x/10)%10); //Just divide the result by 10 and find the remainder

System.out.println(x%10);

}

//Or, you can do that way:

import java.util.Scanner;

public class U1_L5_Activity_One {

public static void main(String[] args) {

Scanner scan = new Scanner(System.in);

System.out.print("Please enter a two digit number: ");

String[] x = scan.nextLine().split(""); //We need it to be a string array, to split the values after "", that is, after each symbol(number)

System.out.println("Here are the digits:");

for(int i = 0; i<x.length; i++) {

System.out.println(Integer.parseInt(x[i])); //Converting the string into int, as you want
