we are looking to factor $23x^2 kx - 5.$ some values of $k$ allow us to factor it as a product of linear binomials with integer coefficients. what are all such values of $k?$
Answers
There are no values of k that allow us to factor the expression \($13x^2 kx - 8$\) as a product of linear binomials with integer coefficients.
To find the values of k that allow us to factor the quadratic expression \(13x^2 kx - 8\) as a product of linear binomials with integer coefficients, let's analyze the expression.
The quadratic expression is of the form \(ax^2 + bx + c\) where a = 13, b = 13k, and c = -8
For factoring it as a product of linear binomials, we need to find two integers m and n such that (mx + n)(px + q) is equal to the given expression.
Expanding the product (mx + n)(px + q), we have:
\((mx + n)(px + q) = mpx^2 + (mq + np)x + nq\)
Comparing this with the given expression \(13x^2 kx - 8,\) we can deduce that mp = 13, mq + np = 13k, and nq = -8.
To find the values of k, we need to determine which values satisfy these conditions and allow us to find integer values for m, n, p, and q.
Considering the prime factorization of 13 and -8, we have \(13 = 13 \cdot 1\) and \(-8 = -1 \cdot 2^3\)
Case 1: m = 13 and p = 1
In this case, the condition nq = -8 becomes 13q = -8.
Since 13 is a prime number, there are no integer solutions for q.
Thus, this case does not allow us to factor the expression with integer coefficients.
Case 2: m = 1 and p = 13
In this case, the condition nq = -8 becomes q = -8 and n = 1.
Therefore, we have mq + np = 13k, which simplifies to -8 + 13n = 13k. Solving for n, we get \(n = \frac{8 + 13k}{13}.\)
For the expression to be factored with integer coefficients, n must be an integer.
Hence, 8 + 13k must be divisible by 13.
It means 8 must be divisible by 13, which is not possible.
Therefore, there are no values of k that allow us to factor the expression \($13x^2 kx - 8$\) as a product of linear binomials with integer coefficients.
In summary, no values of k satisfy the conditions for factoring the expression \(13x^2 kx - 8\) as a product of linear binomials with integer coefficients.

The sum of all the internal angle is \($180^{\circ}$\).
What is Internal angles?The internal angle formed by a closed polygon's sides inside of itself. A shape's interior can contain angles. The closed, side-and-vertex-containing shapes are known as polygons. All of the internal angles of a regular polygon are equal. For instance, the inner angles of a square are all exactly 90 degrees, or the right angle. Triangles always have three inner angles that add up to 180 degrees. Because the other two angles (180°+0°+0°) would not be present, a triangle cannot have an individual angle of 180°.The sum of all the internal angle is \($180^{\circ}$\).

All angles of a triangle add up for 180
We know that there is a 90 degree right angle.
So (x+25)+(2x-10)=180-90
Remove parenthesis since they don't matter in this problem.
x+25+2x-10=90

Step-by-step explanation:
Divisors of number 1479: 1, 3, 17, 29, 51, 87, 493, 1479
Number of divisors: 8
Sum of its divisors: 2160
Answer: plz mark as brainliest
Step-by-step explanation:Here we will define what "the divisors of 1470" means and show you how to find the divisors of 1470.
First, note that in a division problem like x divided by y equals z, x is the dividend, y is the divisor, and z is the quotient as illustrated here:
Dividend / Divisor = Quotient
Divisors of 1470 are all the unique whole number divisors that make the quotient a whole number if you make the dividend 1470:
1470 / Divisor = Quotient
To find all the divisors of 1470, we first divide 1470 by every whole number up to 1470 like so:
1470 / 1 = 1470
1470 / 2 = 735
1470 / 3 = 490
1470 / 4 = 367.5
etc...
Then, we take the divisors from the list above if the quotient was a whole number. This new list is the Divisors of 1470.
The Divisors of 1470 are as follows:
1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 49, 70, 98, 105, 147, 210, 245, 294, 490, 735, and 1470.

Answers
Based on the given information, the terminal side of angle 0 lies in quadrant III.
To determine the quadrant in which the terminal side of angle 0 lies based on the given information, we can analyze the signs of the trigonometric functions:
(a) Since sine < 0 and cotangent < 0, we can determine the quadrant as follows:
Sine < 0 implies that the y-coordinate (vertical component) of the point on the unit circle corresponding to angle 0 is negative.
Cotangent < 0 implies that the x-coordinate (horizontal component) of the point on the unit circle corresponding to angle 0 is negative.
In quadrant III, both the x and y-coordinates are negative. Therefore, quadrant III is the correct answer in this case.
(b) The information provided in this option is incorrect. "esce" is not a recognized trigonometric function, and "cos > 0" does not provide enough information to determine the quadrant.

The numbers round to 56.8 when rounded to the nearest tenth are 56.809, 56.795, and 56.832 respectively.
What is rounding decimals?
The term "rounding decimals" describes the accurate rounding of decimal figures. To the nearest whole, tenth, or hundredth, we can round decimals.
The next place value on the right should be used to round a number to the closest tenth (the hundredths). Simply take away all the digits to the right if it's 4 or fewer. Remove all the digits to the right after adding 1 to the digit in the tenth position if the number is 5 or above.
We need to find the value that rounds to the nearest tenth which results in 56.8
Now, we check all options one by one and rounded them to the nearest tenth
56.85 = 56.9 (rounded to the nearest tenth)
56.809 = 56.8 (rounded to the nearest tenth)
56.749 = 56.7 (rounded to the nearest tenth)
56.08 = 56.1 (rounded to the nearest tenth)
56.795 = 56.8 (rounded to the nearest tenth)
56.832 = 56.8 (rounded to the nearest tenth)
56.72 = 56.7 (rounded to the nearest tenth)
Hence, the required answers are 56.809, 56.795, and 56.832.

D. an independent variable is correlated with the dependent variable but there is no theoretical justification on for the relationship.
Answers
A structural break occurs when we see A. an unexpected shift in time-series data.
It is the change in a time series's data-generating mechanism, it is a phenomenon that occurs when a significant event or structural shift in the economy alters the underlying data-generating mechanism. A structural break can happen for several reasons, including natural catastrophes, changes in economic policy, new inventions, and other reasons that alter the way the data is generated.
In the presence of a structural break, we can't assume that the relationships between variables before and after the break are the same. The primary objective of identifying structural breaks in the time-series is to detect changes in the behavior of the series over time, such as changes in the variance of the series, changes in the mean of the series, and changes in the covariance of the series. So therefore the correct answer is A. an unexpected shift in time-series data, the structural break occurs.

The formula for the final velocity,\(v_{f}\) , in terms of initial velocity, vi, acceleration, a, and time, t is given by \(V_{f}=at+V_{i}\)
A =\((V_{f}-V_{i} )/t\) You can put \(1\) under A and then cross multiply.
\(at =V_{f} -V_{i}\)
Get \(V_{f}\) by adding \(V_{i}\) in both sides of the equation.

How to find the equivalent fractions?Equivalent fractions are defined as fractions that have different numerators and denominators but the same value. For example, 2/4 and 3/6 are equivalent fractions because they are both equal to 1/2. A fraction is part of a whole. Equivalent fractions represent the same part of a whole.
Liam is claiming that the fraction -(5/12) is equivalent to 5/-12.
Thus, we can say that:
The fraction -(5/12) can be described as the opposite of a positive number divided by a positive number. A positive number divided by a positive number always results in a positive quotient and its' opposite is always negative.
