The final result of algebra is: (6x^3 - x^2 - 14x + 5) : (2x - 1) = 3x^2 - x - 7 + 5/(2x-1)This is the simplified form of the given expression.
What is simplification?Simplification is the process of making an expression or equation simpler and easier to understand or work with. In mathematics, simplification often involves combining like terms, removing unnecessary operations, or reducing the number of terms in an expression. The goal of simplification is to obtain an equivalent expression that is clearer, more manageable, and easier to interpret.
Here ,
is the step by step process:
(6x ^ 3 - x ^ 2 - 14x + 5):(2x - 1)
Step 1: Divide 6x^3 by 2x and write the quotient 3x^2.
Step 2: Multiply the denominator (2x - 1) by the quotient (3x^2)
Step 3: Subtract the result from the numerator and bring down the next term of the numerator ( x^2)
Step 4: Repeat the process by dividing the x^2 by 2x and write the quotient -x.
Step 5: Multiply the denominator (2x - 1) by the quotient (-x)
Step 6: Subtract the result from the numerator and bring down the next term of the numerator ( -14x)
Step 7: Repeat the process by dividing the -14x by 2x and write the quotient -7
Step 8: Multiply the denominator (2x - 1) by the quotient (-7)
Step 9: Subtract the result from the numerator and bring down the next term of the numerator (5)
Step 10: We can see that the degree of the remainder is less than the degree of the denominator so we can write the remainder as 5/(2x-1)
So the final result is:(6x^3 - x^2 - 14x + 5) : (2x - 1) = 3x^2 - x - 7 + 5/(2x-1)

Step-by-step explanation:
This problem asks us to find the length of an arc ACB on the circumference of a circle with center O and a radius of 5 cm.
We first must solve for the total circumference (perimeter) of the circle. This is represented by the formula C = 2πr. Hence, the circumference of this circle is:
C = 2π(5) cm
C = 10π cm
Next, we have to find what fraction of 360º the major arc ACB is in order to deduce how much of the circle's total circumference the arc takes up.
[tex]\dfrac{(360 - 50)\textdegree}{360\textdegree} = \dfrac{31}{36}[/tex]
Finally, we can multiply the amount of circumference that arc ACB takes up by the length of the whole circumference to get the length of arc ACB.
[tex]\textrm{Length of arc } ABC = \dfrac{31}{36} \cdot 10\pi[/tex]
[tex]= \dfrac{310}{36} \pi[/tex]
[tex]= \dfrac{155}{18} \pi \textrm{ cm}[/tex]
Answer:
[tex]\textsf{Length of major arc $\overset{\frown}{ACB}$}: \;\; \boxed{\dfrac{155}{18}\pi\; \sf m}[/tex]
Step-by-step explanation:
[tex]\boxed{\begin{minipage}{6.4 cm}\underline{Arc length}\\\\Arc length $= \pi r\left(\dfrac{\theta}{180^{\circ}}\right)$\\\\where:\\ \phantom{ww}$\bullet$ $r$ is the radius. \\ \phantom{ww}$\bullet$ $\theta$ is the angle measured in degrees.\\\end{minipage}}[/tex]
Angles around a point sum to 360°. Therefore:
[tex]\begin{aligned}\implies m \angle BOA&=360^{\circ}-m \angle AOB\\&=360^{\circ}-50^{\circ}\\&=310^{\circ}\end{aligned}[/tex]
Therefore, the given values are:
r = 5 mθ = m∠BOA = 310°To find the length of the major arc ACB, substitute the given values into the arc length formula:
[tex]\begin{aligned}\implies \overset{\frown}{ACB}&=\pi \cdot 5 \cdot \left(\dfrac{310^{\circ}}{180^{\circ}}\right)\\\\&=5\pi \cdot \dfrac{31}{18}\\\\&=\dfrac{155}{18}\pi\; \sf m\end{aligned}[/tex]

There is no evidence to reject the claim that there a difference in the proportion of people who think Red label is produced in Russia.
How to explain the critical value?It should be noted that we want to test the claim at 5% level of significance. The z critical value at 5% level of significance for two tailed test is 1.96.
The test statistic is 0.5. Since the z critical value is greater than the test statistic we do not reject the null hypothesis at 5% level of significance.

Taub goes out to lunch. The bill, before tax and tip, was $11.85. A sales tax of 3% was added on. Taub tipped 24% on the amount after the sales tax was added. How much was the sales tax? Round to the nearest cent.
The value of the sales tax applied to the bill is $0.36
How much was the sales tax?If we have an initial value A, and we increase it by a percentage X, then the new value (after the increase) is given by:
A' = A*(1 + X/100%).
Here we know that the bill before the tax and the tip (it will be the initial value) is:
A = $11.85
And a sales tax of 3% is applied to that bill, then the new amount is:
A' = $11.85*(1 + 3%/100%)
A' = $11.85*(1 + 0.03) = $12.21
The sales tax is equal to the difference between the amount above and the initial value of the bill.

ft.
Answer:
Volume = 2094.40 ft³ (2 d.p.)
Surface area = 1016.64 ft² (2 d.p.)
Step-by-step explanation:
If the diameter of a cone is 20 ft, then its radius is 10 ft since d = 2r.
[tex]\boxed{\begin{minipage}{4 cm}\underline{Volume of a cone}\\\\$V=\dfrac{1}{3} \pi r^2 h$\\\\where:\\ \phantom{ww}$\bullet$ $r$ is the radius. \\ \phantom{ww}$\bullet$ $h$ is the height.\\\end{minipage}}[/tex]
Given:
r = 10h = 20Substitute the given values of r and h into the formula for the volume of a cone and solve for V:
[tex]\implies V=\dfrac{1}{3} \pi \cdot 10^2 \cdot 20[/tex]
[tex]\implies V=\dfrac{1}{3} \pi \cdot 100 \cdot 20[/tex]
[tex]\implies V=\dfrac{1}{3} \pi \cdot 2000[/tex]

The mode is 2.
The mode is the value that appears often in a set of data values.
The mode is a way of expressing, in a single number, important details about a random variable. The numerical value of the model is the alike as that of the mean and median in a normal distribution, and it may be very different in highly skewed distributions.
Given Data :
84, 87,84,88,85,90,91
First, arranging the data in ascending order :
84, 84, 85, 87, 88, 90,91
Now, we have to find how many times this number occurs :
⇒ 84 occurs 2 times
⇒ 85 occurs 1 time
⇒ 87 occurs 1 time
⇒ 88 occurs 1 time
⇒ 90 occurs 1 time
⇒ 91 occurs 1 time
So, the mode is 2.

980
$980 each week. Which inequality represents the number of backpacks,
x
x, that need to be sold each week for the factory to meet this goal? How many backpacks must the factory sell to meet its weekly goal?
Select the inequality that represents this situation and select the correct statement.
The inequality which represents the number of backpacks need to be sold is 40x - (10x + 12,000) ≥ 980. Factory should sell at least 433 backpacks in a week.
What are Linear Inequalities?Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.
Selling price of 1 backpack = $40
Cost to make 1 backpack = $10
Operating expense per week = $12,000
Let x be the number of backpacks which are sold in a week.
Total revenue per week = 40x
Total expense per week = 10x + 12,000
Profit = Revenue - Expense
= 40x - (10x + 12,000)
Factory's goal is to make a profit of at least $980 each week.
40x - (10x + 12,000) ≥ 980
This is the inequality that represents the number of backpacks need to be sold.
Solving the inequality,
40x - (10x + 12,000) ≥ 980
40x - 10x - 12,000 ≥ 980
30x ≥ 980 + 12,000
30x ≥ 12,980
x ≥ 432.67 ≈ 433
Hence factory must at least a total of 433 backpacks to meet it's weekly goal of $980.

A.
x-6
B.
x-3
C.
`X+4
D.
X-2
Using the Factor Theorem, it is found that none of these options represent a linear factor of f(x) = x³ + 7x² + 4x - 12.
How to verify if a term is a factor of the polynomial?The Factor Theorem states that if x - a is a factor of the polynomial y = f(x), then f(a) = 0.
The polynomial for this problem is defined as follows:
f(x) = x³ + 7x² + 4x - 12.
The numeric values for each of the options are given as follows:
f(6) = 6³ + 7(6)² + 4(6) - 12 = 480.f(3) = 3³ + 7(3)² + 4(3) - 12 = 90.f(-4) = (-4)³ + 7(-4)² + 4(-4) - 12 = 20.f(2) = 2³ + 7(2)² + 4(2) - 12 = 32.As none of the values of a have f(a) = 0, none of these terms are linear factors of the polynomial x³ + 7x² + 4x - 12.

Solve the following equation for x 5x+3y=15
Answer:
x=3-3/5y
Step-by-step explanation:
5x+3y=15
5x=15-3y
x=(15-3y)/5
x=3-3/5y
Answer:
x= 3 y=5
Step-by-step explanation:
solving for x
5x + 3y = 15 Zero out the substitute
5x +( 3y * 0) = 15
5x + 0 = 15 Adding by zero can be ommited
5x = 15 Divide both side by 5
x = 3
if solving for y
5x + 3y = 15
(5x*0) + 3y = 15 zero out the substitute
0 + 3y = 15
3y = 15 devide by the number in front of x
y= 5
Explain why multiplying by 8/3 gives the same result as first multiplying by 8 and then multiplying by 1/3
The outcome of multiplying by 8/3 is the same as multiplying with 8 and then by 1/3.
Explain multiplication of fraction?The two fractions that want to multiply come first when multiplying fractions.
You multiply both denominators (the lower numbers) by the sum of the numerators (this same top numbers). Finding the sum of two or maybe more fractions is known as multiplying fractions. When multiplying fractions, a different approach is taken than when adding and subtracting fractions.For the stated number.
The number given is 8/3.
Other set of numbers are-
Multiplying 1/3 with 8.
= 1/3*8
= (1*8)/3
= 8/3, which is equal to the stated number.
Thus, the outcome of multiplying by 8/3 is the same as multiplying with 8 and then by 1/3.
