The function type of the graph with asymptotes, x = 2, and y = 0  is a rational polynomial, where the degree of the numerator is less than the degree of the denominator, and (x - 2) is a factor of the denominator, which is a function of the form;

[tex]f(x) = \frac{1}{(x - 2)}[/tex]

An asymptote is a line to which the output value of a function approaches as the input value becomes very large approaches infinity.

The function type represented by the graph is a polynomial function that has an horizontal asymptote of y = 0, and a vertical asymptote of x = 2

A function has a vertical asymptote at the location at which the denominator approaches zero.

The vertical asymptote of x = 2 , indicates that the denominator approaches zero when x = 2, therefore, (x - 2) is a factor of the denominator

A function has an horizontal asymptote which is the value the function approaches as the input value approaches infinity.

Therefore, the horizontal asymptote of y = 0, indicates that the the degree of the numerator is less than the degree of the denominator

The function type in the question is therefore;

b) For 4 years, the mass of the element is, 19.95 milligrams

c) No, the mass of the radioactive element will never be 0 milligrams.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Now,

The function that represents this situation is,

⇒ y = 35 (1 - 12.9%)ⁿ

Where, 'n' is number of years and 'y' is mass of element.

Now, For 4 years, the mass of the element is,

⇒ y = 35 (1 - 12.9%)ⁿ

⇒ y = 35 (1 - 12.9%)⁴

⇒ y = 35 (1 - 0.129)⁴

Answer:The answer is 20000

Step-by-step explanation:

Based on the given information,

only one triangle is possible.

The correct option is C.

It is a triangle with constant angles of 30, 60, and 90. This triangle is always a right triangle, as one of the angles is 90 degrees. Thus, a right-angled triangle is formed by these angles. Additionally, the right angle is equal to the sum of two acute angles, which will have a 1: 2 or 2: 1 ratio.

Given:

The angle measure of B = π/6 = 30°.

a = 20, and b = 10

That means,

m∠A = 2∠B = 2 x 30 = 60°.

Now, there is only one possibility of a triangle, and that triangle is 30-60-90 triangle.

Hence, only one triangle is possible.

Step-by-step explanation:

2/2=1

8/2=4

12/2=6

The length of the side using cosine rule and approximating to a whole number gives 23

The law of cosines is used to find the missing parts of an oblique triangle when either the two-sided measurements and the included angle measure are known (SAS) or the lengths of the three sides (SSS) are known.

This is expressed as;

b² = a² + c² - 2ac cos b

Plugging in the relevant values gives;

b² = 28² + 41² - 2(28 * 41) cos 32

The required value of C is 3 which makes 16x² - 24x + C a perfect square.

A perfect Square is defined as an integer multiplied by itself to generate a perfect square, which is a positive integer. Perfect squares are just numbers that are the products of integers multiplied by themselves.

The expression is given in the question, as follows:

16x² - 24x + C

(4x)² - 24x + C

As we know that the factoring identity:

(a - b)² = a² - 2ab + b²

After comparing, we have a = 4x and 2ab = 24x

Solving for b:

2(4x)b = 24x

b = 24x/8x

b = 3

So 16x² - 24x + 3 = (4x - 3)²

This means the required value of C is 3 which makes a perfect square.

The value of the equation is y = 4c + 18 , where c is the cost of each teacup and c = $ 6

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

The total cost Rebecca spend on teacups = $ 42

The cost of the large teapot = $ 18

The cost of small teacups be = c

The number of small teacups = 4

So , the equation will be

Total cost Rebecca spend on teacups = cost of the large teapot + ( number of small teacups x cost of small teacups )

Substituting the values in the equation , we get

42 = 18 + 4c

y = 4c + 18   be equation (1) , where y is the total cost

On simplifying the equation , we get

Subtracting 18 on both sides of the equation , we get

4c = 24

Divide by 4 on both sides of the equation , we get

c = $ 6

Therefore , the cost of each teacup is $ 6

Hence , the equation is y = 4c + 18

Answer:

(p o q) = 54

(q o p) = 68

Step-by-step explanation:

Another way to write is (p o q)(3) is p(q(3)).  As you can see, you start with the inner function and 3 is an input in the q(x) function.  Then, the output of this becomes the input of p(x) (the outer function), which yields a final output and the answer:

[tex]p(x) = 4x + 2\\q(x)=5x-2\\\\p(q(3))\\\\q(3)=5(3)-2=13\\p(13)=4(13)+2=54[/tex]

You do the same process for (q o p)(3), which can be written as q(p(3)), where you start with p(3) and then plug in this result as the input for q(x):

[tex]p(x)=4x+2\\q(x)=5x-2\\\\q(p(3))\\\\p(3)=4(3)+2=14\\q(14)=5(14)-2=68[/tex]

The length and width of the rectangular wall of a barn given the area is 22 feet and 5 feet respectively.

Area of the rectangular wall of a barn = 110 square feet

Width of the barn = w

Length of the barn= 2w + 12

Area of a rectangle = length × width

110 = (2w + 12) × w

110 = 2w² + 12w

equate to 0

2w² + 12w - 110 = 0

w² + 6w - 55 = 0

using factorization method of solving quadratic equation

w² + 11w - 5w - 55 = 0

w(w + 11) - 5(w + 11) = 0

(w - 5) (w + 11) = 0

w = 5 or w = -11

The width of the rectangular barn cannot be negative

Therefore,

Width of the barn = w

= 5 feet

Length of the barn= 2w + 12

= 2(5) + 12

= 10 + 12

The given series is geometric when r equals negative three-fifths.

What is geometric series?

The geometric series refers to the total of terms with a common ratio between every pair of neighbouring terms. Geometric series can be of two different types: finite and infinite. The sequence is of the form {a, ar, ar², ar³, …….} where, a is the first term, and r is the "common ratio".

where, r = ar/a = (second term)/(first term)

Given, the series 250 – 150 + 90 – 54 + …

So, r = (-150)/250 = -3/5

or, r = 90/(-150) = -3/5
