what is rational roots theorem?
The Rational Roots Theorem identifies possible rational roots of a polynomial equation in terms of factors of its coefficients.
The Rational Roots Hypothesis, otherwise called the Judicious Zeros Hypothesis, is a numerical hypothesis that assists with recognizing conceivable objective foundations of a polynomial condition. In particular, that's what it expresses on the off chance that a polynomial condition with number coefficients has a sane root, that root should be of the structure p/q, where p is a variable of the consistent term and q is an element of the main coefficient.
For instance, in the event that a polynomial condition has the structure ax^3 + bx^2 + cx + d = 0, and the main coefficient an and the consistent term d are numbers, then, at that point, the conceivable sane foundations of the situation are the quantities of the structure p/q, where p is a component of d and q is a variable of a.
The Normal Roots Hypothesis is valuable in tackling polynomial conditions and deciding if they have reasonable roots.

2. A(an) ______________of a prism is a perpendicular segment that joins the planes of the bases. (The height h is the length of one.)
Answer:
A(an) altitude of a prism is a perpendicular segment that joins the planes of the bases. (The height h is the length of one.)
Step-by-step explanation:
AN ALTITUDE - An altitude of a triangle is a line segment that passes through a vertex and is perpendicular to (i.e. forms a right angle with) the base line (the side opposite the vertex). The expanded base of the altitude is the line that contains the opposing side. The foot of the altitude is the point where the extended base meets the altitude. The area of a triangle can be calculated using altitudes: one half of the product of an altitude's length and its base's length equals the triangle's area. As a result, the longest altitude is perpendicular to the triangle's shortest side. Through trigonometric functions, the heights are also connected to the triangle's sides.
Hence , the answer is an altitude .
please please help me
Answer:
A. 36
Step-by-step explanation:
Right triangle angles in degrees always add up to 180° degrees. In addition, it must have a right angle (hence the name right triangle), which is 90 degrees.
Given the angle in degrees is 54, we can add 90 and 54 and subtract it from 180 to find the missing angle.
\(54+90=144\)
Now, subtract from 180.
\(180-144=36\)
Therefore, the degrees of the missing angle is 36.

The length of a rectangle is 7 centimeters less than three times its width. Its area is 40 square centimeters. Find the dimensions of the rectangle. Use the formula, areaequals length times width.
The length and the width of the rectangle are 1cm and 8/3cm
How to determine the dimensionsThe formula that is used to calculate the area of a rectangle is expressed with the equation;
A = lw
Given that the parameters are;
l is the length of the rectangle.w is the width of the rectangle.A is the area of the rectangle.From the information given, we have that;
Length = 3w - 7
Substitute the values, we have;
40 = (3w - 7)w
expand the bracket
40 = 3w² - 7w
3w² - 7w - 40 = 0
3w² + 15w - 8w - 40 = 0
3w(w + 5) - 8(w + 5) = 0

Create a frequency table for the number of wins using the data provided.
What is the Mean, Mode, and Median for the number of wins?
What is the standard deviation and variation?
How many teams had over 41 wins?
What percent of teams scored below 30 wins?
Create a histogram for the number of wins with a normal curve.
Does our data set for age represent a normal curve (somewhat bell-shaped)? If not, is it positively or negatively skewed?
What is the lowest and highest Z-score for wins and make sure to include that in the SPSS data file (2 points)?
What does the Z-score for the number of wins for 37 (2 points)?
The Mean, Mode, and Median for the number of wins are 37.8; 29, 42; 38 respectively. The standard deviation and variation are 11.15 and 124.26 respectively. 9 teams had over 41 wins. 16.67% of teams scored below 30 wins. Our data set for age does not represent a normal curve, it is positively skewed. The lowest and highest Z-score for wins are -1.78 and 1.99 respectively. The Z-score for the number of wins for 37 is -0.07.
To create a frequency table, we need to categorize the number of wins into intervals and count the number of teams in each interval. We can use the following intervals: 15-24, 25-34, 35-44, 45-54, 55-64.
| Interval | Frequency |
|---------|----------|
| 15-24 | 3 |
| 25-34 | 5 |
| 35-44 | 8 |
| 45-54 | 5 |
| 55-64 | 2 |
To calculate the mean, we add up all the values and divide by the number of values:
Mean = (60 + 44 + 39 + 29 + 23 + 57 + 50 + 43 + 37 + 27 + 49 + 42 + 37 + 29 + 19 + 56 + 51 + 40 + 33 + 26 + 48 + 42 + 31 + 25 + 18 + 53 + 44 + 40 + 29 + 23)/30 = 37.8
To find the mode, we look for the value that appears most often. In this case, it is 29 and 42, both appearing twice.
Mode = 29, 42
To find the median, we need to order the values from smallest to largest and find the middle value. If there is an even number of values, we take the average of the two middle values.
Ordered values: 18, 19, 23, 23, 25, 26, 27, 29, 29, 31, 33, 37, 37, 39, 40, 40, 42, 42, 43, 44, 44, 48, 49, 50, 51, 53, 56, 57, 60
Median = (37 + 39)/2 = 38
To calculate the standard deviation, we first find the variance by subtracting the mean from each value, squaring the result, and then taking the average of those squared differences. The standard deviation is the square root of the variance.
Variance = [(60-37.8)^2 + (44-37.8)^2 + ... + (23-37.8)^2]/30 = 124.26
Standard deviation = sqrt(124.26) = 11.15
To find the number of teams with over 41 wins, we can count the values that are greater than 41:
Number of teams with over 41 wins = 9
To find the percent of teams with below 30 wins, we can count the values that are less than 30 and divide by the total number of teams:
Percent of teams with below 30 wins = (5/30)*100 = 16.67%
To create a histogram, we can use the intervals and frequencies from the frequency table and plot them on a graph with the intervals on the x-axis and the frequencies on the y-axis. We can also add a normal curve by calculating the mean and standard deviation and using a normal distribution function.
The data set for the number of wins does not represent a normal curve, as it is slightly positively skewed (there are more values on the lower end of the distribution).
The lowest Z-score is for the value 18, which is (18-37.8)/11.15 = -1.78. The highest Z-score is for the value 60, which is (60-37.8)/11.15 = 1.99.
The Z-score for the value 37 is (37-37.8)/11.15 = -0.07. This means that the value 37 is 0.07 standard deviations below the mean.

how to find local max and min from graph of derivative
When finding local maxima and minima from the graph of a derivative, we need to identify the points where the derivative changes sign. These points represent the locations of local maxima and minima on the original function.
Finding local maxima and minima from the graph of a derivativeWhen finding local maxima and minima from the graph of a derivative, we need to understand the relationship between the original function and its derivative. The derivative of a function represents the rate of change of the function at any given point. Local maxima and minima occur where the derivative changes sign from positive to negative or from negative to positive. At these points, the slope of the original function changes from increasing to decreasing or from decreasing to increasing.
Steps to find Local Maxima and Minima:Find the critical points by setting the derivative equal to zero and solving for x.Determine the intervals on the x-axis where the derivative is positive or negative.Use the first derivative test to determine whether each critical point is a local maximum or minimum.Check the endpoints of the interval to see if they are local maxima or minima.By following these steps, we can identify the local maxima and minima from the graph of a derivative.

Identify the critical points, Determine the intervals, Analyze the sign changes and Check the endpoints
To find the local maximum and minimum points from the graph of a derivative, you can follow these steps:
Identify the critical points: These are the points where the derivative is either zero or undefined. Find the values of x where f'(x) = 0 or f'(x) is undefined.
Determine the intervals: Divide the x-axis into intervals based on the critical points and any other points of interest. Each interval represents a section of the graph where the derivative is either positive or negative.
Analyze the sign changes: Within each interval, observe the sign of the derivative. If the derivative changes sign from positive to negative, there is a local maximum at that point. If the derivative changes sign from negative to positive, there is a local minimum at that point.
Check the endpoints: Also, check the derivative's sign at the endpoints of the graph. If the derivative is positive at the leftmost endpoint and negative at the rightmost endpoint, there is a local maximum at the left endpoint. Conversely, if the derivative is negative at the leftmost endpoint and positive at the rightmost endpoint, there is a local minimum at the left endpoint.
By following these steps and analyzing the sign changes of the derivative within intervals, as well as checking the endpoints, you can identify the local maximum and minimum points from the graph of the derivative.
