Answer:
The quotient is x^2 + 9x + 6 with a remainder of 6.
Step-by-step explanation:
I used the polynomial long division method to divide the polynomial 2x^3 + 17x^2 + 20x + 6 by 2x + 1.
First, I divided the leading coefficient of the dividend (2x^3) by the leading coefficient of the divisor (2x). This gave me x^2 as the first term of the quotient.Next, I multiplied the divisor (2x + 1) by the first term of the quotient (x^2) to get 2x^3 + x^2.I then subtracted this product from the dividend (2x^3 + 17x^2 + 20x + 6) to get 17x^2 + 20x + 6 as the new dividend.I then brought down the next term of the dividend (17x^2) and divided it by the leading coefficient of the divisor (2x) to get 8.5x as the next term of the quotient.I then multiplied the divisor (2x + 1) by this term (8.5x) to get 17x^2 + 8.5x.I subtracted this product from the new dividend (17x^2 + 20x + 6) to get 0.5x + 6 as the new dividend.I brought down the next term of the dividend (0.5x) and divided it by the leading coefficient of the divisor (2x) to get 0.25x as the next term of the quotient.I multiplied the divisor (2x + 1) by this term (0.25x) to get 0.5x.I subtracted this product from the new dividend (0.5x + 6) to get 6 as the remainder.So the quotient is x^2 + 8.5x + 0.25x which simplifies to x^2 + 9x + 6 and the remainder is 6.

How to find acceleration with velocity and distance?
Answer this functions question
To work out the value of k, we can use the given information that fg(2) = 12. We know that fg(x) is the composition of two functions f and g, so we can write fg(x) = f(g(x))
In this case, fg(2) = f(g(2)) = f(k*2^2) = f(4k)
We know that fg(2) = 12. So we can substitute this value into the equation above:
12 = f(4k)
Since we are only interested in the value of k, we can set the equation equal to 12 and solve for k.
12 = 4k
k = 12/4
k = 3
Therefore, k = 3 is the value of k in the function g(x) = kx^2
On a girl' 10th birthday, her father tarted to depoit ₱5,000 quarterly at the end

His daughter turned 10 years old. Her reward was 5000.
subsequently, she began getting monthly interest compounded at a rate of 15%
She would thus have 5000 (the deposit from her birthday) + 15% = 5750 in her account at the end of the first month.
The amount would have been 5750 + 15% = 6612.50 at the conclusion of the second month.
She would have 6612.50 + 15% + 5000 (quarterly deposit) at the conclusion of the third month, which equals 12,604.38.
When she becomes 17 years old, if you keep doing these calculations, she will have a fun

The sum is an Arithmetic operation that results in the addition of 2 values to get the final value. Let the first number be X and the second be Y. Adding X and Y, we get the resultant as, X + Y = Z.
Sum most commonly means the whole of two or greater numbers delivered collectively; see addition. A summation additionally known as a sum is the result of arithmetically adding numbers or portions. A summation constantly includes a whole range of terms. There can be as few as two terms, or as many as one hundred, a thousand, or one million. some summations include infinitely many terms.

sketch the solution to each system of inequalities
The solution to the system of inequalities y ≤ 2x + 2 and y < -2x - 3 can be represented by a graph. The inequality y ≤ 2x + 2 represents a line with a slope of 2 and y-intercept of 2. The inequality y < -2x - 3 represents a line with a slope of -2 and y-intercept of -3. ( The graph attached)
SYSTEM OF INEQUALITIESThe inequality y ≤ 2x + 2 represents a line in the form y = mx + b, where m is the slope and b is the y-intercept. In this case, the slope is 2 and the y-intercept is 2. To graph this inequality, we can first plot the line by using the y-intercept, which is the point (0,2) on the graph. Then, we can use the slope to find additional points that fall on the line, such as (1,4) or (-1,0). Once we have plotted several points, we can connect them to form the line.
The inequality y < -2x - 3 represents a similar line, but with a different slope and y-intercept. In this case, the slope is -2 and the y-intercept is -3. To graph this inequality, we can use the same process as before by first plotting the y-intercept (0,-3), and then using the slope to find additional points that fall on the line.
The solution to the system of inequalities is the area that lies on one side of the first line and the opposite side of the second line, which is the area between the two lines. This area can be represented by shading the region below the first line and above the second line on the graph. It is important to note that the solution region is not including the lines themselves, because the inequalities are strict inequalities.

The 99th percentile for the mean height of a random sample of 20 adult women is approximately 68.7 inches, which is 3.7 inches above the mean of 65 inches.
The 99th percentile for the mean height of a random sample of 20 adult women can be calculated using the normal distribution. The normal distribution is a bell-shaped curve that describes the probability of a given event occurring. In this case, the mean and standard deviation of the height of adult women is used to calculate the probability of the mean height of a sample of 20 adult women being a certain value. For the 99th percentile, this means that the probability of the mean of the sample of 20 adult women being equal to or less than the value of 68.7 inches is 99%.

How do you write limits?.
A limit is generally written as
[tex]lim _{x- > c} f(x) = L[/tex]
It is read as “the limit of f of x, as x approaches c equals L”
A limit in mathematics is a point at which a function approaches the output for the specified input values. Calculus and mathematical analysis depend on limits, which are also used to determine integrals, derivatives, and continuity. It is employed in the analysis process and constantly considers how the function will behave at a specific point. The idea of the limit of a topological net broadens the definition of the limit of a sequence and relates it to the limit and direct limit in theory category. In general, there are two sorts of integrals: definite integrals and indefinite integrals. The upper limit and lower limit for definite integrals are correctly defined.
Let us consider a real-valued function “f” and the real number “c”, the limit is normally defined as:
[tex]lim _{x- > c} f(x) = L[/tex]
It is read as “the limit of f of x, as x approaches c equals L”. The “lim” shows limit, and fact that function f(x) approaches the limit L as x approaches c is described by the right arrow.
Let us take an example to fully understand how to write limits.

What type of angle turns through 1 360 of a circle?.
An angle that turns through 1/360 of a circle is called a “one-degree angle” and can be used to measure angles.
A degree, generally represented by the symbol ° (the degree), is a unit of measurement for a plane angle, where one full revolution equals 360 degrees.
A degree is the name given to the mathematical unit of measurement for an angle. A protractor is a device used to determine the degree of an angle. Angles can be measured at different angles with different degrees, such as 30°, 45°, 60°, and so on. A complete circle rotates at 360°.
One-degree angles are used to measure angles because they turn around 1/360 of a circle; an angle is said to have an angle measure of n degrees if it turns through n one-degree angles.

a) The probability of event occur is [tex]\frac{1}{5}[/tex].
b) The probability of event not occur is [tex]\frac{4}{5}[/tex].
What is probability?
The likelihood of an event happening is gauged by probability. It is difficult to provide a complete prediction for many events. We can only anticipate the likelihood of an event occurring by using it. The probability might be between 0 and 1, where 0 denotes an impossibility and 1 denotes a certainty.

Note that the answer to the above expression is c = 19.35 or x = -32.35. This is resolved using the Quadratic Formula.
What is the rationale for the above response?
Given
(13+c) * c = 620
⇒ 13c + c² = 620
⇒ c² + 13c -620 = 0 .......................1
We now have a quadratic equation above which we shall solve as follows:
For the above expression (1)
a = 1, b = 13 and c = -620
that is
1c² + 13c + (-620) =0
Applying the Quadratic Formula = [tex]$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$[/tex]
Rather than say c = we say x to avoid confusion
[tex]$x = \frac{-13 \pm \sqrt{13^2 - 4(1)(-620)}}{2(1)}$[/tex]
[tex]$x = \frac{-13 \pm \sqrt{169 + 2480}}{2}$[/tex]
[tex]$x = \frac{-13 \pm \sqrt{2649}}{2}$[/tex]
