Is every number a multiple of 8?
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.

How can we determine the end behavior of a polynomial function?
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 → -∞

What value of x would make Line R Q tangent to circle P at point Q?
x =
Since the value of x cannot be negative x value that makes line RQ tangent to the circle P at point Q is 6.
How to find x value?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.

Isa earns a salary of $32,500 per annum. If he works an average of 34 hours a week calculate his hourly rate of pay
His hourly pay rate is $18.38 if he works 34 hours a week an earns $32,500 per annum.
What does per annum mean?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

How do you change to base 5?
Change to base 5 can be done by dividing the decimal number by 5 and then taking the remainder of the division in reverse order.
The number base is the number that forms the basis for the formation of other numbers in a number system.
The number base that we use a lot every day is the decimal system, which consists of 10 numbers, from 0 to 9. This decimal system is usually called the base 10 number system. Apart from base 10, there are also other base systems, for example, base 2 (biner system), 8 (octal system), and 16 (hexadecimal system) which are usually used in computer / digital systems.
Change of base 10 numbers to other base numbers is done by:
dividing the decimal number by the intended base number, writing the remainder down, repeating the division until the remainder is zero, taking a look at the remainder in reverse order.For example, we want to change 214₁₀ to a base 5 number:
214 : 5 = 42 remainder 4
42 : 5 = 8 remainder 2
8 : 5 = 1 remainder 3
1 : 5 = 0 remainder 1
Thus 214₁₀ = 1324₅

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'.

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.

How do I find the solution to a system?
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.

What strategy do you use to multiply integers?
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).
What is an integer ?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.
Hence, 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).
