What is the scientific notation of 427 thousand

ANSWER TO PART A

The mapping for the reflection in the line [tex]y=x[/tex], is given by

[tex](x,y)\rightarrow (y,x)[/tex].

That is the coordinates swap position .

The only way we can construct a function [tex]f(x)[/tex], such that;

[tex](x, f(x))\rightarrow (f(x),x)[/tex] are equal is when

[tex]f(x)=x[/tex].

So that when [tex]x=a, f(a)=a[/tex] .

The mapping then becomes

[tex](a,a)\rightarrow (a,a)[/tex].

Therefore the function, [tex]f(x)=x[/tex] is the function whose reflection in the line

[tex]y=x[/tex] is itself.

ANSWER TO PART B

The function is symmetrical with respect to the origin. That is to say the function is an odd function.

A function is symmetric with respect to the origin, if it satisfies the condition,

[tex]f(-x)=-f(x)[/tex]

For instance,

[tex]f(a)=a[/tex]

[tex]f(-a)=-a[/tex]

Since

[tex]f(-a)=-a=-f(a)[/tex]

We say the function is symmetric with respect to the origin.

Another way of naming line m is AB

Last one is the answer

Answer: The fourth option. [tex]AB^{<-->}[/tex]

Step-by-step explanation:

BA stands for the segment between B and A, so this is not the correct option.

B (with a double arrow on top) refers to a line, but with only one point we could draw infinite lines, so this is not the correct option)

mB (with a double arrow on top) does not mean anything.

AB (with a double arrow on top) refers to a line that phases through the points A and B, so this is the other way of naming the line m.

The correct answer is C. (x+4)(x+2)(x+5)=0

9 * 9 * 9 = 729. This is also an exponent 9^3.

When you determine the powers you need to multiply the number itself how many times the power says to multiply.

9 raised to the power of 3 is equal to 729.

Given that we need to find that what is 9 to the power of 3.

To calculate 9 to the power of 3, we need to multiply 9 by itself three times.

In mathematical notation, it is written as 9³.

First, we start with 9 and multiply it by itself:

9 × 9 = 81

Next, we multiply the result by 9 again:

81 × 9 = 729

In simpler terms, it means that if you multiply 9 by itself three times, you get the result of 729.

Therefore, 9 raised to the power of 3 is equal to 729.

Final answer:

The daughter is 10 years old, and the mother is 36 years old. We solved two equations simultaneously to find their ages, based on the relationship between their ages and their combined total age.

Explanation:

To solve the problem, we need to set up two equations based on the information provided. Let's denote the daughter's age as d and the mother's age as m. We are given that the mother is 6 years older than 3 times her daughter's age. Formally, this can be expressed as:

m = 3d + 6

Next, we know that their combined ages total 46. This leads to a second equation:

m + d = 46

We can use these two equations to solve for d and m. Substituting the expression for m from the first equation into the second gives:

3d + 6 + d = 46

We simplify this to find d:

4d + 6 = 46

4d = 40

d = 10

Now we can use this to find m:

m = 3(10) + 6

m = 30 + 6

m = 36

So the daughter is 10 years old and the mother is 36 years old.

First we find the slope of the given line as both the lines are parallel therefore their slopes are equal.

To find slope of given line we compare the equation with point slope form i.e.

[tex]y=mx+c[/tex]

On comparing [tex]y=2x+9[/tex]

We get [tex]m=9=slope [/tex]

As the required line is parallel to given line its slope is equal to given line

[tex]m=9[/tex]

Required line pass through[tex](3,1)[/tex]

Using point slope form

[tex]y-y_1=m(x-x_1)[/tex]

Here [tex]m=9, y_1=1, x_1=3[/tex]

Putting the values and solving

[tex]y-1=9(x-3)[/tex]

[tex]y-1=9x-27[/tex]

[tex]9x-y=26[/tex] is the required equation

The answer could be -120 in a simplified form

Answer:

−40+(−20)+(−60) = -40 - 20 - 60= -120

Step-by-step explanation:

The square root of a number can be estimated by locating which two perfect squares it falls between. This provides the two consecutive integers between which the square root lies. For example, the square root of 12 falls between the perfect squares of 9 (3^2) and 16 (4^2), thus it lies between the integers 3 and 4.

To determine between which two integers a square root lies without using a calculator, you can use the method of perfect squares. Perfect squares are numbers that result from squaring integers. For instance, the perfect squares for the integers 1, 2, 3, 4, and 5 are 1, 4, 9, 16, and 25, respectively.

Let's say you wish to locate the square root of 12. You can list the perfect squares until you find two such that 12 falls between them. In this case, we can see that 12 is between the perfect squares 9 (3^2) and 16 (4^2). Therefore, the square root of 12 is between the integers 3 and 4.

This is a straightforward method for roughly determining the value of a square root without using a calculator. Exact values can unfortunately only be determined with the help of a calculator or mathematical tools beyond middle school level.

To find the total fraction of food eaten by George and Silvia, convert each of their portions to have a common denominator and then add the fractions together, resulting in them eating 13/15 of the container.

The question asks us to find the total fraction of the container of Chinese food that George and Silvia ate together. George ate 2/3 of the container, while Silvia ate 1/5 of it. To find the total amount they ate, you need to add these two fractions together.

Calculating the sum of the fractions:

First, find a common denominator, which in this case is 15 (because 3 and 5 both divide evenly into 15).

Convert each fraction to an equivalent fraction with a denominator of 15:

George's portion becomes (2/3) x (5/5) = 10/15

Silvia's portion becomes (1/5) x (3/3) = 3/15

Add the two fractions: 10/15 + 3/15 = 13/15

Therefore, together, George and Silvia ate 13/15 of the container of Chinese food.

Final answer:

The total number of different options for the car model, considering all combinations of features such as color, transmission type, four-wheel drive, air conditioning, and number of speakers, is 240.

Explanation:

To calculate the total number of different options available for a car model, we need to consider all the possible combinations of features. In the given scenario, there are 10 choices for the color, 2 choices for the transmission (automatic or not), 2 choices for four-wheel drive (with or without), 2 choices for air conditioning (with or without), and 3 choices for the number of radio CD speakers (2, 3, or 4).

To find the total number of different combinations, we multiply the number of options for each feature:

Colors: 10 options

Transmission: 2 options (with or without automatic)

Four-wheel drive: 2 options (with or without)

Air conditioning: 2 options (with or without)

Radio CD speakers: 3 options (2, 3, or 4 speakers)

By multiplying these together, we get the total number of configurations:

Total options = 10 (colors) × 2 (transmission) × 2 (four-wheel drive) × 2 (air conditioning) × 3 (speakers)

Total options = 240 different configurations are available for this model of the car.

The amount of snowfall in January was 2 and 3/5 feet while in February it was 1 and 1/3 feet. Upon converting these mixed numbers to improper fractions and subtracting, we find that January had 1 and 7/15 feet more snowfall than February.

The student needs to determine how much more snow fell in January compared to February. The amount of snowfall in January was 2 and 3/5 feet and the amount of snowfall in February was 1 and 1/3 feet.

To do that, first, we need to subtract the snowfall of February from that of January. Before doing so, we should convert the mixed numbers to improper fractions. 2 and 3/5 feet can be converted to 13/5 feet. 1 and 1/3 feet can be converted to 4/3 feet.

So, we subtract 4/3 feet from 13/5 feet: (13/5) - (4/3). For subtacting fractions, we need the denominators to match. Once we equalize the denominators and subtract, we get 1 and 7/15 feet. Therefore, January had 1 and 7/15 feet more snowfall than February.
