A function h(x) is defined by the equation h(x) = + 3.

Which is the graph of h(x)?

Answers

The graph of the function h(x) is attached below.

What is a function?

A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable). In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.

Given function is h(x) = √(x-2) + 3

The radical function is always positive.

Therefore,

x - 2 ≥ 0

x ≥ 2

The domain of the function is [2, ∞)

The value of h(x) is at the lowest value of x that is x = 2.

h(2) = √(2-2) + 3

h(2) = 3

The range of the function is [3, ∞)

The starting point of the function is (2,3).

What is the median of 2/3 and 4?

Answers

The median of 2/3 and 4 is 2.33.

The median is the middle point in a dataset—half of the data points are smaller than the median and half of the data points are larger.

A data set's median value is the point where 50% of the data points have values that are lower or equal to it, and 50% of the data points have values that are higher or equal to it.

To arrange the data points in ascending order for a small data set, count the number of data points (n).

To get the rank of the data point whose value is the median when the number of data points is unequal, multiply the total by 1 and divide the results by 2.

Median = (2/3+4)/2 = 4.66/2 = 2.33

Thus, the median of 2/3 and 4 is 2.33.

What is the HCF of the polynomials x6 3x4 3x² 1 and x³ 3x² 3x 1?

Answers

The HCF of the polynomials x^6 -  3x^4+ 3x² - 1 and x³+ 3x^2+ 3x+ 1 is (x+1)^3.

Let us suppose the Polynomials to be f(x) = x^6 - 3x^4 + 3x^2 - 1  And polynomial g(x) = x^3 + 3x^2 + 3x + 1

Now,  According to the question,

we have f(x) = x^6 - 3x^4 + 3x^2 - 1  

Adding and subtracting 2^x2,

⇒ x^6 - x^4 - 2x^4 + 2^x2 + x^2 - 1

⇒ x^4(x^2 - 1) - 2x^2(x^2 - 1) +1(x^2 + 1)

⇒ (x^2 - 1)(x^4 - 2x^2 + 1)

⇒ (x + 1)(x - 1)(x^4 - 2x^2 + 1)

⇒ (x + 1)(x - 1)(x2 - 1)^2

⇒ (x + 1) (x - 1) (x + 1)^2 (x - 1)2

⇒ (x + 1)^3(x - 1)^3      ----(1)

And, g(x) = x^3 + 3x^2 + 3x + 1

⇒ x^3 + x^2 + 2x^2 + 2x + x + 1

⇒ x^2(x + 1) + 2x(x + 1) + 1(x + 1) ⇒ (x + 1)(x^2 + 2x + 1)

⇒ (x + 1) (x + 1)2 ⇒ (x + 1)3      ----(2)

Now, The HCF of f(x) and g(x) is the common factor of equations (1) and (2)

⇒ (x + 1)^3 .

∴ The HCF of the polynomials (x^6 - 3x^4 + 3x^2 - 1) and (x^3 + 3x^2 + 3x + 1) is (x + 1)^3.

Alvin is 11 years younger than Elga. The sum of their ages is 33. What is Elga's age?

Answers

Answer:

Elga is 22 years old

Step-by-step explanation:

Let A = Alvin's age

Let E = Elga's age

We have the equations:

A = E - 11

A + E = 33

Substitute A = E - 11 from the first equation into the second equation and solve for E

So, we have

A + E = 33

(E - 11) + E = 33

2E - 11 = 33

2E = 44

E = 22 years old

So, Alvin is 11 years old and Elga is 22 years old

What is the y-intercept of the line 5x 3y =- 15?

Answers

The y-intercept is (0, 5). Hence, the intercepts of the equation 5x + 3y = 15 are (3,0) and (0,5).

To find the x-intercept we have to substitute y = 0 into the equation, as follows:

9x - 7*0 = -63

9x = -63

Dividing by 9 at both sides of the equation:

9x/9 = -63/9

x = -7

To find the y-intercept we have to substitute x = 0 into the equation, as follows:

9*0 - 7y = -63

-7y = -63

Dividing by -7 at both sides of the equation:

-7y/(-7) = -63/(-7)

y = 9

x-intercept: −7; y-intercept: 9

What is a multiplicity of 3?

Answers

Multiplicity of 3 is the number of times that the value 3 appears as a root of an equation  is the multiplicity of 3 is 3

Multiplicity of 3 (also known as a 3-fold root) is a mathematical concept used to describe the number of times a certain value appears as a root (or solution) of an equation. Specifically, it refers to the number of times a certain value appears as a root of a given equation when the equation is solved.

For example, the equation x2 = 9 has three solutions: x = 3, -3, and 0. This means that the multiplicity of 3 is 3, because 3 appears three times as a root of the equation. The general formula used to calculate the multiplicity of a given root is:

Multiplicity of x = Number of times x appears as a root of the equation

In this case, the multiplicity of 3 is 3, because 3 appears as a root of the equation three times. Similarly, if there are two solutions, x = -2 and x = 0, the multiplicity of -2 is 2, because -2 appears as a root of the equation twice.

In summary, multiplicity of 3 is the number of times that the value 3 appears as a root of an equation when the equation is solved. In the example above, the multiplicity of 3 is 3.
