What is a number line?

A number line is a visual representation of numbers arranged in a straight line from left to right or from right to left. It is a tool commonly used in mathematics to help visualize numerical relationships, such as addition, subtraction, multiplication, and division.

A typical number line starts at zero in the middle and extends infinitely in both directions, with positive numbers increasing to the right and negative numbers decreasing to the left. The distance between any two points on the number line represents the absolute difference between the corresponding numbers.

Here's a number line using the digits 0-9 exactly once:

-9 --- -8 --- -7 --- -6 --- -5 --- -4 --- -3 --- -2 --- -1 --- 0 --- 1 --- 2 --- 3 --- 4 --- 5 --- 6 --- 7 --- 8 --- 9

Note that the digits are arranged in increasing order from left to right, and that each digit is used exactly once.

Therefore, the digits are arranged in increasing order from left to right, and that each digit is used exactly once.

Answer:

$448.25

Step-by-step explanation:

For her medical expenses, it has to be more than 7.5% of her gross income of $32,500 => 7.5% of $32,500 = $2437.5.

so her deduction for medical expenses is $19,500 - $2437.50 = $17,062.5

so her total itemized deduction is $6,320.00 + $17,062.50 = $23,382.50

Given Kristina will file a single so her standard deduction for 2022 is $12,950.

If she uses standard deduction, her taxable income is 32,500 - 19,500 = 13,000

For the first 10,000 taxed at 10% so it is 10,000 x 10% = $1,000

The next $3000 taxed at 12% = $360

Her total tax is $1,000 + $360 = $1,360

If she uses itemized deduction, her taxable income is 32,500 - 23,382.50 = 9117.5

For the first 10,000 taxed at 10% so it is 9117.5 x 10% = $911.75

The tax saved is $1,360 - $911.75 = $448.25

Answer:

68.1 square units

Step-by-step explanation:

l = Length of rectangle

 = 9 units

w = Width of rectangle

   = 6 units

The dashed lines represent the diameter of the circle. Semi-circle is exact half of a circle. This diameter is parallel to the width of the rectangle and is equal in measurement:

r = Radius of semi-circle

Answer:

To determine how many loaves will not meet quality standards on Tuesday, we need to count the number of integers in the sample that are between 1 and 50, inclusive. From the given sample, we can see that there are 2 integers that fall between 1 and 50: 47 and 4. Therefore, we can predict that 2 loaves will not meet quality standards on Tuesday.

To calculate the difference between the number of sub-standard loaves produced on Monday and the number predicted to be sub-standard on Tuesday, we need to subtract the number of sub-standard loaves on Monday from the number predicted for Tuesday.

Number of sub-standard loaves on Monday = 50

Number predicted to be sub-standard on Tuesday = 2

Difference = 2 - 50 = -48

The difference is -48, which means that there were 48 fewer sub-standard loaves predicted on Tuesday than the number produced on Monday.

The domain are the possible input while the range are the possible output of a function.

(a) The domain = [-√2, √2], the range = [0, 2]

(b) The domain = [-1, 1], the range = [0, 1]

(c) The domain = [-1, 1], the range = [0, -1]

(d) The domain = [0, 2], the range = [0, 1]

(e) The domain = [-(2 + √2), (√2 - 2)], the range = [0, 2]

Reasons:

The given functions can be expressed by the equation; (-x + 1)·(x + 1) = -x² + 1

Therefore, we have;

(a) y = f(x) + 1 = -x² + 1 + 1 = -x² + 2

The x-intercept of the above function are, x = √2, and x = -√2

Which gives;

The domain = [-√2, √2]

The range = [0, 2]

(b) y = 3·f(x) = 3 × (-x² + 1) = -3·x² + 3

At the x–intercepts, we have;

-3·x² + 3 = 0

x = ±1

The domain = [-1, 1]

The maximum value of y is given at x = 0, therefore;

= -3 × 0² + 3 = 3

The range = [0, 1]

(c) y = -f(x) = -(-x² + 1) = x² - 1

At the x–intercepts, x² - 1 = 0

x = ± 1

The domain = [-1, 1]

The minimum value of y is given at x = 0, which is y = -1

The range = [0, -1]

(d) y = f(x - 1) = -(x - 1)² + 1 = -x² + 2·x

At the x–intercepts, we have;  -x² + 2·x = 0, which gives;

(-x + 2)·x = 0

Which gives, x = 0, or x = 2

The domain = [0, 2]

The maximum value of y is given when x = -b/(2·a) = -2/(2×(-1)) = 1

y = f(1) =  -1² + 2×1 = 1

Therefore;

The range = [0, 1]

(e) y = f(x + 2) + 1 = (-(x + 2)² + 1) + 1 = -x² - 4·x - 2

At the x–intercepts, we have;  -x² - 4·x - 2 = 0, which gives;

x = -(2 + √2) or x = x = √2 - 2

The domain = [-(2 + √2), (√2 - 2)]

The maximum value of y is given when x = -4/(2)) = -2

Which gives;

-(-2)² - 4·(-2) - 2 = 2

The range = [0, 2]

Answer:

Please Mark Brainlaiest Answer

Step-by-step explanation:

The best linear approximation for f(x) = cos(x) near x = pi/2 is given by the equation:

y = -(x - pi/2) + 1

This is because the linear approximation should have the same value and slope as the original function at x = pi/2.

At x = pi/2, the value of f(x) = cos(pi/2) = 0. The value of the linear approximation at x = pi/2 is:

y = -(pi/2 - pi/2) + 1 = 1

So, the value of the linear approximation matches the value of the original function at x = pi/2.

The slope of the original function at x = pi/2 is -sin(pi/2) = -1. The slope of the linear approximation is:

y' = -1

So, the slope of the linear approximation also matches the slope of the original function at x = pi/2.

Therefore, the best linear approximation for f(x) = cos(x) near x = pi/2 is:

y = -(x - pi/2) + 1

Hence, the correct option is "y equals negative x plus pi over 2 plus 1".

The probability that the sum of numbers we will get will be 6 is 7/27.

Probability is simply the possibility that something will happen.

Since we don't know how something will turn out, we can talk about the possibility of one outcome or the likelihood of several.

The study of events that fit into a probability distribution is known as statistics.

Probability, or the likelihood that an event will occur, is calculated by dividing the number of favorable outcomes by the total number of potential possibilities.

A coin toss serves as the most simple illustration.

When you flip a coin, there are only two possible outcomes: heads or tails.

So, the probability formula:

P(E) = Favourable events/Total events

We need to get the probability of getting the sum of 6.

Then, calculate as follows:

P(E) = Favourable events/Total events

P(E) = 7/27

Therefore, the probability that the sum of numbers we will get will be 6 is 7/27.

Answer:

12 feet

Step-by-step explanation:

Let x be the length of the shorter part of the pipe.

According to the problem, the longer part is three times as long as the shorter part. Therefore, the length of the longer part is 3x.

We also know that the sum of the lengths of the two parts is equal to the original length of the pipe, which is 16 feet.

So we can write an equation:

x + 3x = 16

Simplifying this equation, we get:

4x = 16

Dividing both sides by 4, we get:

x = 4

So the length of the shorter part is 4 feet, and the length of the longer part is 3 times as long, or 3 × 4 = 12 feet.

Answer:

A right triangle is a type of triangle that has one angle measuring 90 degrees and two acute angles. It has a hypotenuse and two legs, and it is the only type of triangle that the Pythagorean theorem can be applied to. There are different types of right triangles, including isosceles right triangles, 45-45-90 triangles, and 30-60-90 triangles, each with its own unique properties.

Step-by-step explanation:

A right triangle is a type of triangle that has one angle which measures exactly 90 degrees, which we call the right angle. The other two angles are called acute angles and they are always less than 90 degrees.

A right triangle has a special property: the side opposite the right angle is called the hypotenuse. This is the longest side of the triangle and it is always opposite to the right angle. The other two sides are called legs.

One important thing to note is that the Pythagorean theorem only works for right triangles. This theorem tells us that the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs. This formula is often written as a^2 + b^2 = c^2, where a and b are the lengths of the legs and c is the length of the hypotenuse.

There are actually several different types of right triangles. For example, if the two legs have the same length, we call it an isosceles right triangle. If one of the acute angles measures exactly 45 degrees, we call it a 45-45-90 triangle, and if one of the acute angles measures exactly 30 degrees and the other measures 60 degrees, we call it a 30-60-90 triangle. These triangles have special properties that make them useful in many different areas of math and science.

In summary, a right triangle is a type of triangle that has one angle measuring 90 degrees and two acute angles. It has a hypotenuse and two legs, and it is the only type of triangle that the Pythagorean theorem can be applied to. There are different types of right triangles, including isosceles right triangles, 45-45-90 triangles, and 30-60-90 triangles, each with its own unique properties.

The formula for the volume of a d-dimensional sphere of radius r is:

V_d(r) = (π^(d/2) / Γ(d/2 + 1)) * r^d

It should be noted that in the formula, Γ is the gamma function.

Let's break down the formula:

π^(d/2) is pi raised to the power of d/2.

Γ(d/2 + 1) is the gamma function evaluated at d/2 + 1.

r^d is the radius raised to the power of d.

Putting it all together, we get the formula above.

For a 2-dimensional sphere (a circle) of radius r, we have d=2, so:

V_2(r) = (π^(2/2) / Γ(2/2 + 1)) * r^2

= (π / Γ(3/2)) * r^2

= (π / (1/2) * √π) * r^2

= 2πr^2

For a 3-dimensional sphere of radius r, we have d=3, so:

y(1.1) = 20 · 1.1 - 1.87 · 1.1²

y(1.1) = 19.737 m

u = (19.737 m - 18.13 m) / 0.1 s

u = 16.07 m / s

Case III

y(1.01) = 20 · 1.01 - 1.87 · 1.01²

y(1.01) = 18.292 m

u = (18.292 m - 18.13 m) / 0.01 s

u = 16.2 m / s

Case IV

y(1.001) = 20 · 1.001 - 1.87 · 1.001²

y(1.001) = 18.146 m

u = (18.146 m - 18.13 m) / 0.001 s

u = 16 m / s
