A plot of all the ordered pairs for the values in the domain is shown in the graph attached below.

In Mathematics, a domain can be defined as the set of all real numbers for which a particular function is defined. This ultimately implies that, a domain is the set of all possible input values (x-values) to a function and the domain of a graph consist of all the input numerical values which are shown on the x-axis.

Based on the values given for the domain of this function, the ordered pairs would be calculated as follows:

When x = -8, we have;

y = 1/2(-8) + 1

y = -3

Ordered pair = (-8, -3)

When x = -4, we have;

y = 1/2(-4) + 1

y = -1

Ordered pair = (-4, -1)

When x = 0, we have;

y = 1/2(0) + 1

y = 1

Ordered pair = (0, 1)

When x = 2, we have;

y = 1/2(2) + 1

y = 2

Ordered pair = (2, 2).

When x = 6, we have;

y = 1/2(6) + 1

The set of the values of the side lengths of an isosceles triangle that has a hypotenuse that is 8 units long is: C. 4√2, 4√2, and 8.

An isosceles triangle is a type of triangle that has two sides that are of the same length, while the third side has a different length.

The hypotenuse is found in a triangle that has a right angle. This means the triangle is a right triangle, and therefore, according to the Pythagorean theorem, the square of the length of the hypotenuse is equal to the sum of the squares of the other legs of the triangle.

Considering the definition given above, it means the right triangle we are looking for must be a right triangle is isosceles, which hast two equal sides and an hypotenuse that is 8 units long.

The values of the set of lengths, 2, 4, and 8 cannot be the isosceles triangle because they have three different side lengths.

8,8, and 16 do not conform to the Pythagorean Theorem because:

16² ≠ 8² + 8²

4√2, 4√2, and 8 conform to the Pythagorean Theorem because:

8² = (4√2)² + (4√2)²

64 = 64

Therefore, the values of side lengths are: C. 4√2, 4√2, and 8.

Answer:

m = -21.

Step-by-step explanation:

To solve this equation, we can use the distributive property to expand the left side and the right side of the equation:

19(2m - 16) = 13(2m + 4)

38m - 304 = 26m + 52

Then we can combine like terms on both sides of the equation to obtain:

38m - 26m = 52 - 304

12m = -252

Finally, we can divide both sides of the equation by 12 to find the value of m:

12m / 12 = -252 / 12

m = -21

Therefore, the value of m that satisfies the equation is m = -21.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

3 = 4k is an equation.

We have,

Volume of a gas (V) ∝ 1/ Pressure of a gas (P)

This can be written as,

Volume of a gas = K / Pressure of a gas

K = VP

Now,

P =1.8 x [tex]10^6[/tex] Pascals

V = 2.1 x [tex]10^{-8}[/tex] m³

K = VP = 1.8 x 2.1 x [tex]10^{-2}[/tex]

k = 3.78 x [tex]10^{-2}[/tex] pascal m³

Now,

P = 4.1 x [tex]10^4[/tex] Pascals

V = K/P =  3.78 x [tex]10^{-2}[/tex] Pascal m³ / 4.1 x [tex]10^4[/tex] Pascals

V = 0.923 x [tex]10^{-6}[/tex] m³

Now,

V = 7.1 x [tex]10^{-9}[/tex] m³

P = k/V =  3.78 x [tex]10^{-2}[/tex] Pascal m³ / 7.1 x [tex]10^{-9}[/tex] m³

Step-by-step explanation: y+9=-3(x-4)......given equation

This equation can be expanded further and simplified

y+9=-3x+12

We want to put the equation into the form y=mx+b so we can read its characteristics

To do this we need to get y on its own. We must take 9 from both sides

The equation has a gradient or slope or m =-3 and it cuts the y-axis at +3 or is the yintercept

A function f such that f '(x) = 3x^3 and the line 81x + y = 0 is tangent to the graph of f is f(x) = 3x^4/4 + 729/4.

In the given question, we have to find a function f such that f'(x) = 3x^3 and the line 81x + y = 0 is tangent to the graph of f.

The given function is f'(x) = 3x^3.

No integrating on both side,

f(x) = [tex]\int3x^3dx[/tex] + C

f(x) = 3x^4/4 + C

As given, the line 81x + y = 0 is tangent to the graph of f.

So, slope at point of tangent; f'(x) = -81

So, 3x^3 = -81

Divide by 3 on both side, we get

x^3 = -27

Taking cube root on both side, we get

x = -3

So putting the value of x in 81x + y = 0, we get

y = 243

Thus, f(x) passes through (-3, 243).

So, 243 = 3/4(81) + C

Multiply by 4 on both side, we get

972 = 243 + 4C

Subtract 243 on both side, we get

4C = 729

Divide by 4 on both side, we get

C = 729/4

So, f(x) = 3x^4/4 + 729/4

Step-by-step explanation:

Note:

[tex]P=[/tex] Perimeter

[tex]L=[/tex] Length

[tex]W=[/tex] Width

The perimeter of a rectangle is the sum of all its sides.

We can say

[tex]P=2L+2W[/tex]

This is the equation to find the perimeter of a rectangle.

We are given the perimeter which is 42.

We are also given that the length is the sum of twice its width and 3.

So we can write

The measurement of angles △XYZ are ∠X = 59°, ∠Y = 89°, and ∠Z = 32°.

The measurement of angles △LMN are ∠L = 59°, ∠M = 89°, and ∠N = 32°.

What is angle?

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.

Given that, △XYZ and △LMN are similar triangle.

Since the triangles are similar, thus the measurement of triangles are similar.

Therefore,

∠X = ∠L, ∠Y = ∠M, ∠Z = ∠N.

∠Y = ∠M = 89° and ∠Z = ∠N = 32°.

The sum of all interior angles of triangle is 180°.

∠X + ∠Y + ∠Z = 180°

∠X + 89° + 32° = 180°

∠X + 121° = 180°

Subtract 121° from both sides:

∠X  = 59°

∠X = ∠L = 59°.

To find the sum of 2/3 + (-1)/3, you can first convert the fraction to an equivalent fraction with a common denominator. In this case, the common denominator would be 3. 2/3 can be written as 2 x (3/3) = 2/3 and -1/3 can be written as -1 x (3/3) = -1/3. Then, you can add the numerators and the denominator will remain the same. So, the sum of 2/3 + (-1)/3 is 1/3.

The exponential function in the form y = ab^x is y = 18(7)^x

From the question, we have the following parameters that can be used in our computation:

Points: (0, 18) and (3,6174).

The above can be represented as

(x, y) = (0, 18) and (3,6174).

An exponential function is represented as

y = ab^x

Where

a = y when x = 0

This means that

a = 18

So, we have

y = 18b^x

At (3,6174), we have

6174 = 18b^3

So, we have

343 = b^3

Using the normal distribution, the middle 50% would be expected to be in the range of 250 to 270 days.

Using the central limit theorem, for the samples of 36, the middle 50% would be expected to be in the range of 258 to 262 days.

A sort of continuous probability distribution for a real-valued random variable is the normal distribution or the Gaussian distribution.

Normal Distribution of Probabilities

The z-score formula, which for a measure X, in a set with mean and standard deviation, is given by: can be used to address problems with normal distributions.

Z = (X - μ)/σ

The z-score calculates the measure's standard deviation from the mean.

A p-value, or percentile of X, is assigned to each z-score.

Mean (μ) = 260.

Standard deviation (σ)= 15 .

The normal distribution is symmetric, which means that the middle 50% is between the 25th percentile and the 75th percentile.

The 25th percentile is X when Z has a p-value of 0.25, so X when Z = -0.675.

The 75th percentile is X when Z has a p-value of 0.75, so X when Z = 0.675.

Lower bound:

Z = (X - μ)/σ

⇒ -0.675 = (X - 260)/15

⇒ X - 260 = -0.675*15

⇒ X - 260 = -10.125

⇒ X = 260 - 10.125

⇒ X ≈ 250

Upper bound:

Z = (X - μ)/σ

⇒ 0.675 = (X - 260)/15

⇒ X - 260 = 0.675*15

⇒ X - 260 = 10.125

⇒ X = 260 + 10.125

⇒ X ≈ 270

The middle 50% of pregnancies would be in the range of 250 to 270 days.

For sample of 36: By the Central Limit Theorem, the standard deviation of the sampling distribution of sample means of size n is given by .

Sample of 36, thus n=36, s=15/√36

⇒ s=15/6

⇒ s=2.5

Lower bound:

Z = (X - μ)/s

⇒ -0.675 = (X - 260)/2.5

⇒ X - 260 = -0.675*2.5

⇒ X - 260 = -1.69

⇒ X = 260 - 1.69

⇒ X ≈ 258

Upper bound:

Z = (X - μ)/s

⇒ 0.675 = (X - 260)/2.5

⇒ X - 260 = 0.675*2.5

⇒ X - 260 = 1.69

⇒ X = 260 + 1.69
