Answer:

14=90

Step-by-step explanation:

You're on the right track with writing the measure of MK = angle N. To figure out angle N we can use the right angle sign right next to it (at LNK). We know that line JK is a straight line meaning it's angle = 180. Therefore, if LNK is 90 degrees, then N also has to be 90 degrees because 90+90=180. From there we know that the measure of MK = 90 due to MK and N being vertical angles.

I unfortunately can't help you with 16, but I hope I was able to help with 14

The slope - intercept form of the equation that relates the number of people and the cost of entering the museum is y = 8x + 4

The slope - intercept form is:

y = mx + b

Where:

m = slope or the cost per person

b = y - intercept or the residual cost

The cost per person to enter the museum is:

= Difference between cost of three people and two people

= 28 - 20

= $ 8

The residual is:

= Total cost for two people - Cost of two people

= 20 - ( 8 x 2 )

= $ 4

The slope intercept form of the relationship between the number of people and the cost of entering the museum is therefore:

y = 8x + 4

The domain of the graphed relation is:

D : {-9, -7, -5, -2, 1, 3}

For a relation y = f(x), we define the domain as the set of the possible inputs, this is, the possible values of x.

On the graph we can see some points (x, y) graphed, where x is the value on the horizontal axis.

We can see that the graphed points are:

The product of the polynomial [tex]\frac{6(x^{2} -1)(6x - 1)}{8(x+1)}[/tex] is [tex]\frac{18x^{2} - 21x + 3}{4}[/tex].

A polynomial is an equation that solely uses the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables. Variables are sometimes known as indeterminates. x² + 4x + 7 is an illustration of a polynomial with a single indeterminate x.

An algebraic expression known as a polynomial requires that all of its exponents be whole numbers. Any polynomial must have variable exponents that are non-negative integers. Although a polynomial contains variables and constants, we are unable to divide a polynomial by a variable.

The degree of a polynomial is the highest or biggest exponent of the variable in the polynomial. Using Descartes' Rule of Signs, the degree is used to calculate the greatest number of polynomial problem solutions.

The Polynomials is [tex]\frac{6(x^{2} -1)(6x - 1)}{8(x+1)}[/tex]

Simpliest form of the polynomial

[tex]\frac{6(x+1)(x-1)(6x - 1)}{8(x+1)} = \frac{6(x-1)(6x- 1)}{8} = \frac{3(6x^{2} -7x + 1)}{4} = \frac{18x^{2} - 21x + 3}{4}[/tex]

The complete table for the given quadratic equations is:

3.                 3                6                3                1

When the middle term of a quadratic equation is split, we must rewrite the expression as the sum or difference of the two parts. We must split the middle phrase into two halves in order to determine the sum or difference of the words.

1. x² + 2x - 15

Split the middle term

= x² + 5x - 3x - 15

= x(x + 5) - 3(x + 5)

= (x - 3)(x + 5)

So, a = 1, b = -3, c = 1, d = 5

2. 2x³ + 6x² - 20x

= 2x(x² + 3x - 10)

= 2x(x² + 5x - 2x -10)

= 2x(x(x + 5) - 2(x + 5))

= 2x(x - 2)(x + 5)

So, a = 1, b = -2, c = 1, d = 5

3. 9x² + 21x + 6

= 3(3x² + 7x + 2)

Use splitting middle term method

= 3(3x² + 6x + x + 2)

= 3(3x(x + 2) + 1(x + 2))

= 3(x + 2)( 3x + 1)

= (3x + 6)(3x + 1)

So, a = 3, b = 6, c = 3, d = 1

The value of {h} is equivalent to 6/5.

A function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that function takes.

Given is the function as follows -

(1/5) + h = (7/5)

We can write the function as -

(1/5) + h = (7/5)

h = 7/5 - 1/5

h = (7 - 1)/5

h = 6/5

Therefore, the value of {h} is equivalent to 6/5.

The system of equations is solved and the amount of 45 % copper is 34.74 pounds and the amount of 64 % copper alloy is 20.26 pounds

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 total amount of the third alloy = 55 pounds

So , the amount the 45 % of copper alloy = x

And , the amount of 64 % of copper alloy = ( 55 - x )

The percentage of amount of alloys is given by the equation ,

( 45/100 )x + ( 64/100 ) ( 55 - x ) = ( 52/100 ) 55

On simplifying the equation , we get

0.45x + 0.64 ( 55 - x ) = 0.52 ( 55 )

0.45x + 35.2 - 0.64x = 28.6

Subtracting 35.2 on both sides of the equation , we get

-0.19x = -6.6

Divide by 0.19 on both sides of the equation , we get

x = 34.736

x ≈ 34.74 pounds

Hence , the amount of 45 % of copper alloy is 34.74 pounds and the amount of 64 % copper alloy is 20.26 pounds

present salary is $19,025.625.

By dividing the principle by the cost of borrowing, the rest of the time, and other factors, simple interest is determined. Simple return equals principal plus interest plus hours is the concept used in marketing. The easiest way to compute interest is by using this method. The most typical method for calculating income is as a portion of the principal amount. For example, if he takes $100 from a buddy and pledges to pay back the loan at 5% interest, he will just pay his share of the 100% involvement. $100 (0.07) = $7. When you borrow money, you must pay interest, and you must charge interest when they lend it.

Here,

Given : 4.25 % raise

Salary =  $18,250

=> Simple interest = P*R*T /100

=> 18250 * 4.25 * 1 /100

=> 775.625

Thus,

Present salary = 18250 +  775.625 = 19,025.625.

The inverse of the function → f(x) = 2x + 5  is → f⁻¹(x) = (x/2) - (5/2).

Inverse of a function can be calculated by following the steps mentioned below -

According to the question, the equation given is as follows

y = f(x) = 2x + 5

y = 2x + 5

Replace 'y' with 'x', we get -

x = 2y + 5

Now, solve for y -

2y = x - 5

y = (x/2) - (5/2)

Replace 'y' with f⁻¹(x) -

f⁻¹(x) = (x/2) - (5/2)

Hence, the inverse of the function → f(x) = 2x + 5  is → f⁻¹(x) = (x/2) - (5/2).

The y-intercept of the equation is 5.

What are intercepts?

A point on the y-axis known as an intercept is where the line's slope passes.

X-intercept and Y-intercept are the two main intercepts. The line's x-intercept and y-intercept are located where the line crosses the x and y axes, respectively.

We are given two points (2, 11) and (3, 14).

First, we need to form the equation.

General form of a point slope form of equation is y-y₁=m(x-x₁)

Here, y₁= 11 and x₁= 2, y₂= 14 and x₂=3

Now, m = (y₂ - y₁) / (x₂ - x₁)

⇒m = (14 - 11) / (3 - 2)

⇒m = 3

Thus, we get the equation as y-11 = 3(x-2)

In order to find the y-intercept, we need to put x=0

So,

⇒y-11 = 3(0-2)

⇒y = -6 + 11

⇒y = 5

Hence, the y-intercept of the equation is 5.

We must convert a given number to decimal form in order to determine whether it is rational or irrational. If the decimal has repeated decimal patterns and is ending or nonterminating, the number is rational.

If not, it is illogical. However, if we look at the example of 5 = 2.2360679774997896409173..., we can see that it is non-terminating and lacks repeated decimal patterns. It is therefore an irrational number. Checking whether a number is a natural number, a whole number, an integer, or a fraction of integers is another method of determining whether it is rational. It is a rational number if it fits into one of these categories.

Given the expression is √x+11,

√a It cannot be expressed in the form of a ratio, So, it is an irrational number.

The value of x has to be something which upon adding 11, gives perfect square root, in order to become rational number.
