Answer:

i think its 637

Step-by-step explanation:

Here is a possible program that meets the requirements: import java.util.Scanne imporjava.util.InputMismatchException; public class RestaurantOccupancy {
  public static void main(String[] args) {
     Scanner input = new Scanner(System.in);
     int occupancy = 0;
 

The program starts by importing the Scanner and InputMismatchException classes from the java.util package.

In the main method, we declare a Scanner object named input and an integer variable named occupancy initialized to 0.

The program enters a while loop that continues as long as the occupancy is less than 10. Inside the loop, we prompt the user to enter the number of people entering or leaving the restaurant, read the input as an integer using input.nextInt(), and store it in a variable named delta.

We then add delta to the occupancy variable to update the current occupancy, and print it to the console using System.out.println(). If an InputMismatchException is thrown (i.e., the user enters a non-integer value), we catch the exception, read the next token as a string using input.next(), and print an error message to the console.

Once the occupancy reaches or exceeds 10, the while loop exits, and we print a message indicating that the occupancy limit has been reached and the program is exiting.
Here is a step-by-step explanation for a program that meets the described requirements:

1. Import the necessary libraries:
```java
import java.util.Scanner;
import java.util.InputMismatchException;
```

2. Create a class and the main method:
```java
public class RestaurantOccupancy {
   public static void main(String[] args) {
```

3. Initialize the required variables and create a Scanner object for reading input:
```java
       int occupants = 0;
       int change;
       Scanner input = new Scanner(System.in);
```

4. Create a loop that continues until the number of occupants equals or exceeds 10:
```java
       while (occupants < 10) {
```

5. Use a try-catch block to handle the `InputMismatchException` exception:
```java
           try {
               change = input.nextInt();
               occupants += change;
               System.out.println("Number of people in the restaurant: " + occupants);
           } catch (InputMismatchException e) {
               input.next(); // Discard the invalid input
           }
```

6. Close the while loop, Scanner object, and the main method:
```java
       }
       input.close();
   }
}
```

Answer

Step-by-step explanation:

The first step when multiplying fractions is to multiply the two numerators. The second step is to multiply the two denominators. Finally, simplify the new fractions. For example

In other words, multiply linearly and simplify

If you have to multiply mixed fractions, first you transform the fraction from mixed to improper and then multiply, for example

The law of signs for multiplication is

   Multiplying fractions starts with the multiplication of the given numerators, followed by the multiplication of the denominators. ...

   Example: Multiply the following fractions: 1/3 × 3/5.

   Solution: We start by multiplying the numerators: 1 × 3 = 3, then, multiply the denominators: 3 × 5 = 15.

Thus, the linearization of the function F(x)=x at x=25 is L(x) = x.

Given the function F(x)=x and we are to find the linearization L(x) of the function F(x)=x at x=25.

Linearization:

The linearization of a function f(x) at a point x=a is the approximation of the function by a line near the point (a,f(a)).

The linearization is a linear approximation of a function that is valid only for a small range of values of x. It is defined as:

L(x) = f(a) + f′(a)(x−a)where f'(a) is the derivative of f(x) at x=a.

To find the linearization L(x) of the function

F(x)=x at x=25, we need to calculate f(25) and f′(25).f(25)

= 25 (the function value at x=25)f′(25) = 1 (the derivative of the function with respect to x)

Therefore, L(x) = f(25) + f′(25)(x−25)

L(x) = 25 + (1)(x−25)L(x) = x

Since the function F(x)=x is already linear, the linearization L(x) is just the function itself.

Therefore, the linearization of the function F(x)=x at x=25 is L(x) = x.

Thus, the answer is:

Linearization is the linear approximation of a function that is valid only for a small range of values of x.

The linearization of a function f(x) at a point x=a is the approximation of the function by a line near the point (a,f(a)).

To find the linearization L(x) of the function F(x)=x at x=25, we need to calculate f(25) and f′(25). f(25) = 25 (the function value at x=25) and f′(25) = 1 (the derivative of the function with respect to x).

Therefore, L(x) = f(25) + f′(25)(x−25). L(x) = 25 + (1)(x−25). L(x) = x.

Since the function F(x)=x is already linear, the linearization L(x) is just the function itself.

Answer:

y= 4x + 9

Step-by-step explanation:

y= 4x+5

y= 4(x+ 5/4)

m, gradient= 4

rule if parallel: their gradients are equal

rule if perpendicular : m1*m2=-1

parallel gradient, m1=4

passes through (-2, 1) so x= -2,  y= 1

y - 1= 4(x -- 2)

y= 4x + 9

The line parallel to y= 4x+ 5 passing through point (-2, 1) is y = 4x + 9

The given equation is:

y = 4x + 5

Compare y = 4x + 5 with the equation y = mx + c

m = 4, c = 5

The equation parallel to y = 4x + 5 will also have a slope, m = 4

The point-slope form of the equation of a line is given as:

y - y₁ = m(x - x₁)

substitute m = 4, x₁ = -2 and y = 1 into the equation above

y - 1 = 4(x - (-2)

y - 1 = 4(x + 2)

y - 1 = 4x + 8

y = 4x + 8 + 1

Answer: $622 in one work week.

Step-by-step explanation:

We need to start by multiplying $4,600 by 7% in order to calculate her commission sales prophets (=$322.0). It is given that her weekly salary is $300.

Add her sales prophet rewards ($322) to her given weekly salary income (300)

$322+$300= $622.0

The total weight of the package was 20 pounds, given the total shipping cost was $3.45, using the total cost function, C(P) = 1.65 + 0.12(P - 5), where P is the weight of the package in pounds.

In the question, we are given that a package weighs P pounds, P being a whole number. To ship this package by express costs $1.65 for the first five pounds and 12c for each additional pound. The total shipping cost was $3.45.

We are asked for the package weight in pounds.

First, we design a general cost function.

The cost is given to be $1.65 for the first 5 pounds, and 12c for each additional pound.

The weight of the package is given to be P pounds.

We assume the total cost function to be C(P), a function of the weight of the package, P pounds.

Thus, the total cost function can be shown as the sum of $1.65 and 12c or $0.12 multiplied with (P - 5), as it is the cost for additional pounds after 5 pounds.

Thus, the total cost function, C(P) = 1.65 + 0.12(P - 5).

Now, we are given that the total shipping cost was $3.45.

Thus, to find the weight of the package, we equate the total cost function, C(P) to 3.45, to get:

1.65 + 0.12(P - 5) = 3.45,

or, 1.65 + 0.12P - 0.6 = 3.45,

or, 0.12P + 1.05 = 3.45,

or, 0.12P = 3.45 - 1.05,

or, 0.12P = 2.40,

or, P = 2.40/0.12 = 20.

Thus, the total weight of the package was 20 pounds, given the total shipping cost was $3.45, using the total cost function, C(P) = 1.65 + 0.12(P - 5), where P is the weight of the package in pounds.

It has also been defined as a society where agriculture and handicrafts have developed, social strata have developed, cities and the state have emerged, writing is known and high-quality literary and artistic works are created.

The first civilizations emerged in the region of Mesopotamia, approximately 6000 years ago. For the development of these it was eminently necessary that individuals had developed cognitive and physical capacities that allowed them a correct cultural assimilation with respect to their peers, and also a correct relationship between them without the development of conflicts.

Three are 27 rows of saplings

Step-by-step explanation:

Since 21 saplings were left out of 750 saplings, the number of saplings arranged will be 750 -21 = 729 saplings

We were told that the number of saplings arranged per row is equal the number of rows

So let’s say the number of saplings arranged per row is x

Automatically, the number of rows too will be x

So the total number of saplings arranged will be;

x * x = x^2

This is equal to 729

x^2 = 729

x^2 = 27^2

Since power is equal, equate the base

This means that x = 27
