No, not every number is a multiple of 8.

Multiple:

A multiple is a number that can be produced by multiplying another number by an integer.  

Integer:

An integer is a whole number with no fractional part.

For example, 1, 2, 3, 4, and 5 are integers. The number 0 is also an integer because it is not divisible by any whole number greater than 1. The largest integer that can be represented as a fractional value is called the fractional part of the value.

A multiple of 8 is a number that can be divided by 8 with no remainder.

For example, 8, 16, 24, 32, etc. are multiples of 8, but 7, 9, 15, etc. are not.

So, every number cannot be a multiple of 8.

Answer:

perpendicular slope to line k is 4

Step-by-step explanation:

calculate the slope of line k using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (4, 3 ) and (x₂, y₂ ) = (8, 2 )

m = [tex]\frac{2-3}{8-4}[/tex] = [tex]\frac{-1}{4}[/tex] = - [tex]\frac{1}{4}[/tex]

given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{1}{4} }[/tex] = 4

the slope of a line perpendicular to line k is 4

His hourly pay rate is $18.38 if he works 34 hours a week an earns $32,500 per annum.

Per annum denotes yearly or annually. It is a phrasing used frequently to describe interest rates. In sentences like "I have a 4% mortgage loan" or "This bond pays interest at a rate of 6%," "per annum" is frequently left out.

An illustration is when a supplier offers a credit customer a 2% early-payment discount for paying an invoice in 10 days as opposed to the full amount in 30. In this instance, the supplier forfeits 2% of the invoice amount in exchange for receiving payment 20 days early.

We recalculate the amounts and multiply both the "2%" and the "20 days" by 18 to get the rate per year. The annual rate that results is roughly 36%.

Isa works 34 hours a week

There are total 52 weeks a years

In a year the time he works is = 52 × 34 h

                                                  =  1768 hours

His annual salary is $32,500

Then his hourly rate of income = 32500/1768

                                                    = 32500/1768

                                                    = $18.38

Thus, his hourly pay rate is $18.38 if he works 34 hours a week an earns $32,500 per annum.

An inequality is a relationship that compares two numbers or other mathematical expressions in an unfair manner. When comparing the sizes of two numbers on the number line, it is most frequently used. The graph of each equation or inequality is given the attachment.

The graph, visual depiction of statistical information or a functional relationship between variables. Graphs serve a predictive purpose because they can highlight broad trends in the quantitative behaviour of data. However, they can be inaccurate and occasionally deceptive as mere approximations.

Most graphs have two axes: a horizontal axis for a set of independent variables and a vertical axis for a set of dependent variables. A broken-line graph is the most typical type of graph, with time usually acting as the independent variable.

No. [tex]3x^{2}[/tex] is not an exponential function. It is a quadratic function. In this, exponent is not a variable.

There is a variable in the exponential function called exponent. 3x would have been an example of an exponential function. In this function, the exponent is not variable, it is 2. Therefore this is a quadratic function, not an exponential one. The exponential function is a type of mathematical function which are helpful in finding the growth or decay of population, money, price that are growing or decay exponentially. A basic exponential function from its definition is of the form f(x) = b x, where 'b' is a constant and 'x' is a variable. generally it refers to the positive valued function of a real variable. it can be extended to the complex numbers or generalized to other mathematical objects like matrices.

The inverse of the equation y = - 4x + 3 is y = (3 - x)/4.

First to be an inverse function that function needs to one to one function, meaning every different preimage must correspond to a different image.

We can obtain the inverse of a function by switching the variables x and y with their respective positions and solving for y in terms of x.

Given, An equation y = - 4x + 3.

To find the inverse we'll first solve for 'x'.

Therefore,

y = - 4x + 3.

4x = 3 - y.

x = (3 - y)/4.

Now, we'll interchange the positions of 'x' and 'y'.

Therefore,

x = (3 - y)/4 becomes,

y = (3 - x)/4.

1/12 tank in 1/3 hour.

1/12 is one-twelfth of the tank.

there are 12 twelfths in an unit. The tank has 12 one-twelfth parts, so you need to fill 12 times 1/12 of the tank.

Since it takes 1/3 hour to fill 1/12 of the tank, it will take 12 × 1/3 ghour tio fill the entire tank.

If the system consists of 2 variables we can use the method of elimination or substitution to get the answer easily.

In the method of elimination from the two given sets of equations, we make one of the coefficients of a variable the same so that when in the next step when we will subtract them they will get canceled out and we will get the value of one of the variables which after substituting in one of the equation we'll get the value of another variable.

If we have more than 2 variables the method of row reduction using a matrix is the best way to solve the system. In the system we make an augmented matrix of the coefficients of the variables and row reduce them in such a way that when we multiply the matrix with the row matrix we get the values of the variables easily.

Integer multiplication is equivalent to repetitive addition, which is adding an integer a predetermined number of times. For instance, adding 4 three times results in the number 12 (4 + 4 + 4).

All whole numbers and negative numbers are considered integers.

This means that if we combine negative numbers with whole numbers, a collection of integers results.

An integer, which can comprise both positive and negative integers, including zero, is a number without a decimal or fractional portion. Integers include things like -5, 0, 1, 5, 8, 97, and 3,043. Z is a representation of a collection of integers.

A straight line of numbers is shown visually as a number line.

This line is used to compare integers that are spaced equally apart on an infinite line that extends horizontally on both sides.

The collection of integers can be shown on a number line much like other sets of numbers.

Since the value of x cannot be negative x value that makes line RQ tangent to the circle P at point Q is 6.

From the circle P, if Q is the tangent, It implies that at the tangent line, it is perpendicular to the radius.

Using Pythagorean theorem;

PQ² + RQ² = PR²

Where PQ = 9

RQ = 12

PR = (x + 9)

Applying (x + 9) to the formula

(9)² + (12)² = (x + 9)²

Using algebraic expression; (a + b)² = a² + 2ab + b²

x² + 18x + 81 = 36 + 144

x² + 18x + 81 = 225

x² + 18x + 81 - 225 = 0

x² + 18x - 144= 0

By employing the quadratic formula,

[tex]x =\frac{ -b+/-\sqrt{b^{2} - 4ac} }{2a}[/tex] where a = 1, b = 18 and c = -144

[tex]x =\frac{ -18+/-\sqrt{18^{2} - 4(1)(-144)} }{2(1)}[/tex]

[tex]x =\frac{ -18+/-\sqrt{324 + 576} }{2}[/tex]

[tex]x =\frac{ -18+/-\sqrt{900} }{2}[/tex]

[tex]x =\frac{ -18+/- 30}{2}[/tex]

[tex]x =\frac{ -18 + 30}{2}[/tex]

[tex]x =\frac{ 12}{2}[/tex]

x = 6

[tex]x =\frac{ -18 - 30}{2}[/tex]

[tex]x =\frac{-48}{2}[/tex]

x = -24

Knowing that the value of x cannot be negative then, the quadratic equation that yielded 12/2 = 6 makes the value of x = 6.

The end behavior of a polynomial function can be determined by looking at the degrees of the terms in the polynomial.

Generally, the highest degree term will indicate the end behavior of the function. For example, if the highest degree term is x^2, then the end behavior of the function will be that it will approach positive infinity as x approaches positive infinity and it will approach negative infinity as x approaches negative infinity. This can be illustrated by the following calculation:

f(x) = x^2 + 4x + 8

As x approaches positive infinity, the x^2 term will become much larger than the other terms, causing the polynomial function to approach positive infinity.

f(x) → +∞ as x → +∞

Similarly, as x approaches negative infinity, the x^2 term will again become much larger than the other terms, causing the function to approach negative infinity.

f(x) → -∞ as x → -∞
