find the cardinality of x , if x={-n,...,-2,-1,0,1,.....n}

Answers

Answer = 2n + 1
Cardinality is the number of elements in a given mathematical set.
In this set,the cardinality is 2n + 1
Explanation the n is a certain number and also in this set it has both negative and positive n
Before the number of elements in this set excluding one (which is 0 is 2n then the other one is added
Hence the cardinality is 2n + 1

Geometric shapes are mathematical shapes that include squares and triangles

How to prove the shape is a square

The side lengths of a square are congruent, and the adjacent sides are perpendicular.

So, we start by calculating the side lengths using the following distance formula

[tex]d = \sqrt{(x_1 -x_2)^2 + (y_1 -y_2)^2}[/tex]

Using the above formula, we have:

[tex]AB = \sqrt{(3-2)^2 + (4+2)^2} = \sqrt{37[/tex]

[tex]BC = \sqrt{(2+4)^2 + (-2+1)^2} = \sqrt{37[/tex]

[tex]CD = \sqrt{(-4+3)^2 + (-1-5)^2} = \sqrt{37}[/tex]

[tex]DA = \sqrt{(-3-3)^2 + (5-4)^2} = \sqrt{37}[/tex]

The above shows that the side lengths of the square are congruent.

Next, calculate the slope of the sides using:

[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]

So, we have:

[tex]m_{AB} = \frac{4 +2}{3 -2} = 6[/tex]

[tex]m_{BC} = \frac{-2 + 1}{2+4} = -\frac 16[/tex]

[tex]m_{CD} = \frac{-1 -5}{-4+3} = 6[/tex]

[tex]m_{DA} = \frac{5 -4}{-3-3} = -\frac 16[/tex]

Notice that the opposite slopes are congruent, and the adjacent slopes are opposite reciprocal.

The above highlight, and the equal side lengths show that the figure (1) is a square

How to prove the shape is a right isosceles triangle

The legs of a right isosceles triangle are congruent, and the legs are perpendicular.

So, we start by calculating the lengths of the legs using the following distance formula

[tex]d = \sqrt{(x_1 -x_2)^2 + (y_1 -y_2)^2}[/tex]

Using the above formula, we have:

[tex]XY = \sqrt{(5-4)^2 + (-1-4)^2} = \sqrt{26[/tex]

[tex]XZ = \sqrt{(5-0)^2 + (-1+2)^2} = \sqrt{26[/tex]

The above shows that the legs of the right isosceles triangle are congruent.

Next, calculate the slope of the legs using:

[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]

So, we have:

[tex]m_{XY} = \frac{5-4}{-1 -4} = -\frac{1}{5}[/tex]

[tex]m_{XZ} = \frac{5-0}{-1+2} = 5[/tex]

Notice that the slopes are opposite reciprocal.

The above highlight, and the equal legs show that the figure (2) is a right isosceles triangle

Find the equation of the line having a slope of 4 and a y-intercept on (0,3)

Answers

[tex]\mathbb{FINAL\:ANSWER:}[/tex]

[tex]\huge\boxed{\sf{y=4x+3}}[/tex]

[tex]\mathbb{SOLUTION\:WITH\:STEPS:}[/tex]

Hi! Hope you are having a nice day!

We are given the slope of the line and its y-intercept.

So, let's find the equation.

The y-intercept is written in the form (0, b).

No worries! b is the y-intercept.

Thus, the y-intercept equals 3.

Now, let's find the equation of the line with a slope of 4 and a y-intercept of 3.

We can write the equation in Slope-intercept form:

y=mx+b, where m stands for the slope and b stands for the y-intercept.

Since we have both m and b, we can just plug the given values:

y=4x+3 ✓

Hope you could understand everything.

why does -2 to the power of 3 produce the same answer as (-2) to the power of 3

Answers

Answer:

because it's an odd exponent

Step-by-step explanation:

-2^3 = -(2*2*2)

(-2)^3 = (-2)*(-2)*(-2)

if it was ^4 the sign would be flipped:

-2^4 = -(2*2*2*2) = -16

(-2)^4 = (-2)*(-2)*(-2)*(-2) = 16

The way to put this is that any negative base raised to an odd-numbered power, will result in a negative result, whereas any negative base raised to an even-numbered power, will result in a positive result, with the EXCEPTION of a negative base written WITHOUT grouping symbols. For instanse:

[tex]\displaystyle -1000 = -10^3 \\ -1000 = [-10]^3 \\ \\ BUT \\ \\ 10000 ≠ -10^4\:[-10000 = -10^4] \\ 10000 = [-10]^4[/tex]

AB of the right triangle ABC is twice the length of the leg BC. Find the number of degrees in angle ABC

Answers

Answer:

It is 45 degree angle

Step-by-step explanation:

AB is the tilted angle of the triangle

BC is the height and the vertical part of the triangle

If AB is 10 then BC is 5 and AC is possibly about 6-8

If that is so then 2 right triangles is a square

A square has 90 degree angles on any angle

Divide 90 by 2 which is 45 because a right triangle is half of a square

Therefore angle ABC is 45 degrees

Rong Huang can buy 4 books with 2/9 of his money. He can buy another 8 such books and 2 identical bags with the rest of his money. How many such bags can he buy with the original sum of money?

Answers

Step-by-step explanation:

remember, that a/a = 1, and this is always the "whole" in such fraction scenarios.

in our case here : 9/9 or 3/3.

4 books for 2/9 of his money.

8 books for then 2× 2/9 = 4/9 of his money.

that is together

12 books for 6/9 = 2/3 of his money.

that leaves 3/9 = 1/3 of his money for the 2 identical bags.

so, 1/3 of his money for 2 bags.

how many bags for the whole (3/3) money ?

1/3 × x = 3/3

x = 3

he could have bought 3×2 = 6 bags with the original sum of money.

A rectangular prism has a length of 10 in., a width of 2 in., and a height of 3 1/2 in. The prism is filled with cubes that have edge lengths of 1/2 in.How many cubes are needed to fill the rectangular prism

Answers

Solution:

Step-1: Find the volume of the rectangular prism.

Volume of rectangular prism: LBH=> Volume of rectangular prism: (10)(2)(3 1/2)=> Volume of rectangular prism: (10)(2)(3.5)=> Volume of rectangular prism: (2)(35)=> Volume of rectangular prism: 70 in³

Step-2: Find the volume of the small cube.

Volume of cube: L³=> Volume of cube: (1/2)³=> Volume of cube: (1³/2³)=> Volume of cube: (1/8)

Step-3: Divide.

70 ÷ 1/8 => 70 x 8=> 560 cubes

Thus, 560 cubes are needed to fill the rectangular prism.

Consecutive means beside. Numbers 2 and 3 are consecutive integers. Given this question, numbers 6, 8, and 9 could possibly be the answer. However, we don't know this, so let's represent the 6 as x, 7 as x+1. 9 is x+2. We know when these are added together the sum is 57, so 3x+3 should be 57. Now, solve as a normal algebraic question.
