Find the quotient of x^5 − 2x^3 + 1 / x^2 − 6 by any appropriate method. Given that the initial expression is of the form a(x)/b(x) , rewrite the quotient in the form q(x)+r(x)/b(x) , noting that r(x) could possibly be zero. Identify q(x) , r(x) , and b(x) .
q(x)=
r(x)=
b(x)=
The quotient in the form q(x)+r(x)/b(x) which is equal to the x^3 +4x +(24x +1 divided by x^2 − 6), and the identification q(x) , r(x) , and b(x) are as follow :q(x) = x^3 +4x
r(x) = 24x +1
b(x) = x^2 − 6
Given details in the following question are as follows:
x^5 − 2x^3 + 1 is divided by x^2 − 6
By using the divisor method :
x^5 − 2x^3 + 1 / x^2 − 6 = x3 +(4x^3+1 is divided by x^2 − 6)
= x^3 +4x +(24x +1 divided by x^2 − 6)
where we can see that the q(x) +r(x)/b(x) is equal to the x^3 +4x +(24x +1 divided by x^2 − 6)
q(x) = x^3 +4x
r(x) = 24x +1
b(x) = x^2 − 6
The quotient in the form q(x)+r(x)/b(x) which is equal to the x^3 +4x +(24x +1 divided by x^2 − 6)
What is the divisor method?A divisor divides a number into equal groups. The number that is being divided is called the dividend and the number that divides it is called the divisor.
Divisor Formula
The divisor formula is formed for two situations - with or without a remainder:
If the remainder is 0, then Divisor = Dividend ÷ Quotient.

It takes you 53 seconds to walk from the first (ground) floor of a building to the third floor. How long will it take you to walk from the first floor to the sixth floor (at the same pace, assuming all floors have the same height)?
The time required to walk from the first to sixth floors is 132.5 seconds.
fundamental arithmetic operations:There are four fundamental arithmetic operations: addition, subtraction, multiplication, and division. Among these four procedures, division is one of the most important in our daily tasks. It is the division of a large group into equal smaller groups. Divide 25 by 5, for example. For this example, the division fact will be 25 /5 = 5.
According to the given data:Given:
It takes 53 seconds to walk from the first to the third floor.
There are two floors between the first and third floors.
So, assuming that each floor is the same height, we can state that the number of seconds it takes to travel to one story is 53/2.
We have,
= 53/2
= 26.5 sec
From the first to the sixth story, there are 5 stores.
As a result, the time required to walk from the first to sixth floors is:
= 26.5 x 5
= 132.5 sec
Also can be written as:
132.5 seconds
= 2.20 minutes
= 2 minutes 12 seconds

7. If jenny uses 24 yards of blue yarn then, she needs to use 6 yards of white yarn to make a scarf.
8. Jenny cannot use 42 yards of blue yarn and maintain the same ratio of blue to white yarn since the values of the two fabrics are different.
Given, Jenny wants to make a scarf that uses 24 yards of blue yarn.
how many yards of white yarn will she need = ?
from the given situation:
let the blue yarn be x yards.
and the white yarn be y yards.
Jenny uses blue yarn, 4 times the number of yards of white yarn.
⇒ x = 4y
therefore, scarf = blue yarn + white yarn
= x + y
= 4y + y
given that jenny uses 24 yards blue yarn.
therefore,
4y + y = 24 + y
5y = 24 + y
5y - y = 24
4y = 24
y = 24/4
y = 6
hence she needs to use 6 yards of white yarn.
8. If Jenny uses 42 yards of blue yarn then :
4y + y = 42 + y
5y = 42 + y
5y - y = 42
4y = 42
y = 21/2
y = 10.5
hence ratio of blue yarn to white yarn is:
42:10.5
both are not same , hence she can't keep the same ratio while using 42 yards of blue yarn

A decimal number has 2 digits to the right of it's decimal point. If we round it to the nearest tenth, the result is 18.6. What is the maximum possible value of this decimal ?
This number can have a maximum value of 18.64.
What are decimal numbers?The decimal numeral system is the most widely used system for representing both integer and non-integer numbers. It is the Hindu-Arabic numeral system's extension to non-integer numbers. Decimal notation is the method of representing numbers in the decimal system. Non-recurring (non-repeating or terminating, for example), recurring (repeating or non-terminating, for example), and decimal fractions are the three types of decimals (a.k.a. converting a decimal into a fraction whose denominator is a power of ten).So, when rounded to the nearest tenths, the number is 18.59.
Now, look at the number to the right of it.If that number is 5 or higher, we round the 5 to a 6.But if that number is 4 or lower, the number remains a 5.18.55 rounded to the nearest tenths equals 18.6 (because the number to the right of 5 is 5, we round up to 18.6)18.54 rounded to tenths = 18.5 (because the number to the right of the 5 is 4, so we round it to 18.5).Therefore, this number can have a maximum value of 18.64.

Step-by-step explanation:
The area of a rectangle is length times width. A square is a type of rectangle that has four equal sides, so if we know one side we know all four.

In order from least to greatest
[(3/4), -(√5), -3, 2.5 and 0] when arranged in ascending order will be in the order of [tex][(-3),-(\sqrt{5}),0,\frac{3}{4},2.5][/tex].
As per question statement, we are provided with 5 random numbers:
[(3/4), -(√5), -3, 2.5 and 0].
We are required to rearrange the above mentioned numbers in their ascending order.
We know from basic mathematical knowledge that, any number of integer or fraction with a negative sign is less than Zero or any other positive number.
Here, we have two negative quantities [-(√5) and (-3)]. Since [tex]4 < 5 < 9\\or, \sqrt{4} < \sqrt{5} < \sqrt{9} \\or,2 < \sqrt{5} < 3\\or,(-2) > [-(\sqrt{5})] > (-3)\\or,(-3) < [-(\sqrt{5})] < (-2)[/tex]
That is, we have established our required relation between the negative numbers.
We also know that, zero is the midpoint of the number line and any other positive number is greater than zero while any negative number is less than zero. Hence, [tex][(-3) < -(\sqrt{5}) < 0][/tex] and [tex](0 < \frac{3}{4}),(0 < 2.5)[/tex].
Now, between (3/4) and 2.5, since (3/4) is a proper fraction, it means that (3/4) is less than 1, and since (1 < 2.5), therefore, [tex](\frac{3}{4} < 2.5)[/tex].
Hence, [(3/4), -(√5), -3, 2.5 and 0] when arranged in ascending order will be in the order of [tex][(-3),-(\sqrt{5}),0,\frac{3}{4},2.5][/tex].

Answer:
m = -1/2b = 3Step-by-step explanation:
You want the slope-intercept equation of the line through (2, 2) and parallel to the line through (-1, 6) and (1, 5).
SlopeThe parallel line will have the same slope. The slope is given by the equation ...
m = (y2 -y1)/(x2 -x1)
m = (5 -6)/(1 -(-1))
m = -1/2
InterceptWe need to find the y-intercept of the desired line. Solving the equation for "b", we get ...
y = mx +b
b = y -mx . . . . . . . subtract mx to find b
b = 2 -(-1/2)(2) . . . . use m=-1/2 and (x, y) = (2, 2)
b = 2 +1
b = 3
The equation we want is ...
y = -1/2x +3
