The polynomial that represents the volume of the rectangular box is 3x² - x - 24 = 0
The dimension of the rectangular box are 9 inches, 8 inches and 3 inches.
How to find volume of a rectangular box?The volume of the rectangular box can be expressed as follows:
volume of the rectangular box = l w h
where
l = length of the rectangular boxw = width of the rectangular boxh = height of the rectangular boxTherefore,
w = x inches
l = 3x
h = 3x - 1
volume of the rectangular box = 72x
Therefore, the polynomial that represents the volume of the rectangular box is as follows:
72x = 3x × x × (3x - 1)
72x = 3x²(3x - 1)
72x = 9x³ - 3x²
9x³ - 3x² - 72x = 0
3x(3x²- x - 24) = 0
3x² - x - 24 = 0
Therefore,
x = 3 or - 8 / 3
we can only use positive values.
Hence, the dimension of the rectangular box is as follows:
w = 3 inches
l = 3(3) = 9 inches
h = 3(3) - 1 = 8 inches

1. In △NBA, BO is a median. If NO=x+3 and OA=2x-9, what is the value of x?
2.In △MTV, TPis an angle bisector. If m∠MTP=12 and m∠MTV=3x-3, find the value of x.
Answer:
Step-by-step explanation:
1 . In the given triangle ΔNBA BO is a median.
By applying the property of median it divides the opposite side into two equal parts.
Therefore,
NO = OA ...(a)
We have,
NO = x+3 and OA = 2x-9
from (a)
NO = OA
x+3 = 2x-9
∴ 3+9 = 2x-x
∴ x = 12
∴ The Value of x is 12.
Que 2 - In ΔMTV
Given - TP is an angle bisector
m∠MTP = 12 , m∠MTV = 3x - 3.
Ans - TP is an angle bisector which means it divides the angle into two equal parts. (By angle bisector theorem)
∴ m∠MTP = m∠VTP ..... (a)
m∠MTV = m∠MTP + m∠VTP
∴m∠MTV = 2(m∠MTP)
∴3x-3 = 2(12)
∴3x-3 = 24
∴3x = 24 + 3
∴3x = 27
∴ x = 27/3
∴ x = 9
∴ The Value of x is 9.
Select whether ←→ A B and ←→ C D are parallel, perpendicular, or neither. Graph each line on a separate sheet of paper to verify your answer. A ( − 6 , − 9 ) , B ( 8 , 19 ) , C ( 0 , − 4 ) , D ( 2 , 0 )
The slope of AB = 2
The slope of CD = 2
Both lines are parallel lines.
How to Determine Parallel and Perpendicular Lines?The lines that are perpendicular to each other have slope values that are negative reciprocal of each other.
For example, if the a line's slope is a, the line that is perpendicular to it will have a slope of -1/a. This is because the negative reciprocal of a is -1/a, and (a)(-1/a) = -1.
On the other hand, the lines that are parallel to each other will have the same slope value.
Given the following:
A(−6 , −9)
B(8, 19)
C(0, −4)
D(2, 0)
Find the slope (m) of AB:
Slope of AB = (19 -(-9))/(8 -(-6))
Slope of AB = 28/14
Slope of AB = 2
Find the slope (m) of CD:
Slope of CD = (0 -(-4))/(2 - 0)
Slope of CD = 4/2
Slope of CD = 2
The graph of both lines are shown below.
Thus, the slope of AB and CD are the same, therefore, we can conclude that lines AB and CD are parallel to each other.

The probability of getting heads on both occasions will be 0.25.
How to calculate the probability?It should be noted that probability simply means the likelihood that a particular event will happen.
In this case, if I flip a coin, i have a 50 percent chance that it will land on heads and after the first coin flip, we still have a 50 percent chance that the next flip will result in a head.

Suppose that kellogg believes that the average weight for a box of frosted flakes is 18 ounces. As part of a quality control effort, they sample 30 boxes and find that the mean of those 30 boxes is 18. 2 ounces. Historical records show that the standard deviation of the filling process is 0. 32 ounces. How likely is it for the sample mean to have been 18. 2 ounces or larger if the actual mean is 18 ounces and the standard deviation of the filling process is 0. 32 ounces?.
There is a 0.0003 chance that the sample mean was 18.2 ounces or more if the actual mean is 18 ounces.
What exactly is mean?In mathematics, the mean is the average of a set of data, which is calculated by adding all the numbers together and then dividing the result by the total number of numbers. For instance, the mean for the set of data 8, 9, 5, 6, 7 is 7, since 8 + 9 + 5 + 6 + 7 = 35, and 35/5 = 7.So, let Y be a random variable with box weights.
μ = 18 ouncesSD = 0.32 ouncesThese are the sample size and mean:
Sample size (n) = 30Sample mean (y) = 18.2N's standard deviation is then roughly followed by Y ( μ = 18, SD = 0.32).
Z score is displayed as:
[tex]z=\frac{\sqrt{n}(y-u)}{S D}[/tex]Where z has a mean of 0 and a standard deviation of 1 and is a normal standard variable.
Given that the standard deviation is given and that sample size n is 30. y roughly follows the Normal distribution.
If the sample mean was 18.2 ounces or more and the actual mean was 18 ounces, the probability that this was the case is given as:
[tex]\begin{aligned}&P[Y \geq 18.2]=P\left[\frac{\sqrt{n(y-u)}}{S D} \geq \frac{\sqrt{30}(18.2-18)}{0.32}\right. \\&=P\left[z \geq \frac{\sqrt{30}+0.2}{0.32}\right] \\&=P\left[z \geq \frac{1.0954}{0.32}\right] \\&=P[z \geq 3.4233] \\&=0.0003\end{aligned}[/tex]

A new television set was recently purchased for the common room in a residence hall for $520.00 including tax. If the tax rate is 4%, find the price of the television set before taxes.
Let's use the variable x to represent the price of the television set before taxes.
If the tax rate is 4%, then the original price is multiplied by 1.04, so it is equal 1.04x.
The final price is $520, so we have:

For given triangle, the value of x is 22.
In this question, we have been given three angles of triangle.
We need to find the value of x.
We can observe that (6x - 7)° is an exterior angle.
So, the third angle of the triangle is 180° - (6x - 7)°
We know that the sum of the all angles of the triangle is 180°
2x° + (103 - x)° + [180° - (6x - 7)°] = 180°
2x + 103 - x + 180 - 6x + 7 = 180
2x - x - 6x + 103 + 180 + 7 = 180
-5x + 290 = 180
-5x = 180 - 290
-5x = -110
x = 22

What is a constant polynomial?
A constant Polynomial is defined as a polynomial is a function of the form f(x) = a

Thus, examples of constant Polynomials are f(x) = 5, g(x) = -11 , h(y) = 7/4
Now, we are given the polynomial expression;
P(x) = (2m - 4)x² + (5 - n)x + 13
From the definition of constant Polynomials, we can say that;

Kylie just accepted a job at a new company where she will make an annual salary of $67000. kylie was told that for each year she stays with the company, she will be given a salary raise of $3000. how much would kylie make as a salary after 3 years working for the company? what would be her salary after tt years?
Since the situation can be since as an arithmetic sequence, her salary after 3 years is $73,000. After t years, her salary is a function of t, that is a(t) = 64000 + 3000 t
The given situation can be seen as an arithmetic sequence. The nth term of an arithmetic sequence is given by the formula:
a(n) = a(1) + (n - 1) . d
Where:
a(1) = the first term
d = the common difference.
The problem can be translated into an arithmetic sequence with:
a(1) = $67000
d = $3000
Kylie's salary after 3 years is a(3),
a(3) = a(1) + (3 - 1) . d
a(3) = Kylie's salary + 2 . 3000 = 73000
Hence, after 3 years, Kylie's salary is $73,000
Her salary after t years, means n = t. Therefore,
a(t) = a(1) + (t - 1) . d
a(t) = 67000 + (t -1) . 3000

m arcRPQ
Answer:
arc RPQ = 305°
Step-by-step explanation:
• the angle at the centre is equal to the measure of the arc that subtends it.
arc RP = ∠ ROP = 125°
∠ QOS and ∠ ROP are vertically opposite angles and are congruent, so
∠ QOS = 125° and so arc SQ = 125°
RS is a straight angle , then
∠ POS = 180° - 125° = 55°
arc PS = 55° ( arc subtending the angle at centre

The value of x is 26° and y is 9°.
What is linear pair angles ?A pair of neighboring angles created by the intersection of two lines is known as a linear pair of angles. When two angles share a vertex and an arm but do not overlap, they are said to be adjacent angles. Due to their formation on a straight line, the linear pair of angles are always complementary. So, the total of two angles in a pair of lines is always 180 degrees.
The value of x and y are : x= 26° and y= 9°.
As a linear pair, (5x - 17)° + (3x - 11)° = 180°.
or, 8x - 28°= 180°
8x = 180° + 28°
Therefore, the value of x is 26°.
Now,
3x - 11°= 3×26°-11° = 67°
Again,
67°+90°+(2y+5)° = 180° { being linear pair}.
157°+2y+5° = 180°
or, 2y + 162° = 180°
