Which of the following is a polynomial with a degree of 5, has three distinct zeros, has two zeros with a multiplicity of 2, and has a negative leading coefficient?

Which Of The Following Is A Polynomial With A Degree Of 5, Has Three Distinct Zeros, Has Two Zeros With

Answers

Answer 1

Answer:

Graph 2

Explanation:

The required polynomial is to have the following properties:

• Three distinct zeros

,

• Two zeros with a multiplicity of 2

,

• A negative leading coefficient

,

• A degree of 5.

For the polynomial to satisfy the first two conditions, it must intersect the x-axis at exactly three points and touch the x-axis at a point.

For the polynomial, to satisfy the last two conditions, we use the leading coefficient test.

By one of the conditions of the leading coefficient test: When the degree is odd and the leading coefficient is negative, the graph rises to the left and falls to the right.

The graph that satisfies all these condition is attached below:

The second graph is the correct one.

Answers

Answer:

1.) The slope is 2

2.) The y-intercept is (0,1)

3.) y = 2x + 1

Step-by-step explanation:

1.) you can either use rise over run or the slope formula. rise over run is quicker, but here's the formula:

you can use any two points on the line, i chose (2, 5) and (1, 3)

\(\frac{(y_{2}-y_{1})}{(x_{2}-x_{1})} \\\)

\(\frac{3-5}{1-2} \\\\\frac{-2}{-1} \\\\\frac{2}{1} \\\\2\)

2.) for the y-intercept, you just look for the point where the graph crosses the y-axis and x = 0

3.) using the formula y = mx + b, m being the slope and b being the y-intercept, you take the information above and plug it in to get y = 2x + 1

To use the two sample t procedure to perform a significance test on the difference of two means, we assume:

Answers

We assume that the population standard deviation are known, the samples from each population are independent, the population is normally distributed if we use t test of two samples.

Given T test of significance has been used.

T test is a statistical test that is like z test. Z test is used when n>30 and t test is used when n<30. It is used in hypothesis testing.

We know that there are many test which can be used to test a hypothesis.

The requirements to perform a two sample t procedure are as follows:

1)The two samples have equal variance. Hence the variance should be known.

2) The samples for which the two sample t procedure is performed must be independent.

3) The data are in alignment with the normal distribution probability.

4) The sample are random samples taken from different respective population.

Hence when two sample t procedure is performed we have to assume population standard deviation is known and population is normally distributed.

a train traveled at an average speed of 45 miles per hour for 40 minutes, and at an average speed of 60 miles per hour for 1 hour. what was the average speed of the train, in miles per hour, for the trip?

Answers

So, the average speed of the train is 54.09 miles per hour.

To calculate the average speed of the train for the entire trip, you need to find the total distance traveled and the total time traveled.

First, you can convert the time traveled at each speed to hours. 40 minutes is equal to 40/60=0.67 hours. So the total time traveled is 1+0.67=1.67 hours.

To find the total distance traveled, you can use the formula: distance = speed x time. At 45 mph, the distance traveled is 45 x 0.67 = 30.15 miles. At 60 mph, the distance traveled is 60 x 1 = 60 miles. Therefore, the total distance traveled is 30.15 + 60 = 90.15 miles.

Finally, you can use the formula: average speed = total distance / total time.

Average speed = 90.15 miles / 1.67 hours = 54.09 miles per hour.

The indicated function y1(x) is a solution of the given differential equation. Use reduction of order or the formula y2=y1(x)∫e−∫P(x)dxy12(x)dx, as instructed, to find a second solution y2(x). y" + 2y' + y = 0 ; y1=xe−x
A) y2 =e^{-4x}
B) y2 =e^x
C) y2 =e^{-2x}
D) y2 =e^{-x}

Answers

To find a second solution, y2(x), for the given differential equation y" + 2y' + y = 0 using the reduction of order or the formula y2 = y1(x)∫e^(-∫P(x)dx)y1^2(x)dx, we will substitute the given solution y1(x) = xe^(-x) into the formula.

The second solution is y2(x) = e^(-2x) (Option C).

To explain the solution, let's start by substituting y1(x) = xe^(-x) into the formula for y2(x):

y2(x) = xe^(-x) ∫e^(-∫(2x)dx)(xe^(-x))^2dx

Simplifying the expression, we have:

y2(x) = xe^(-x) ∫e^(-2x)(x^2e^(-2x))dx

Integrating the expression inside the integral, we get:

y2(x) = xe^(-x) ∫(x^2e^(-4x))dx

Integrating this expression, we find:

y2(x) = xe^(-x) (-1/4) * (x^2e^(-4x) - 2∫xe^(-4x)dx)

Simplifying further, we have:

y2(x) = xe^(-x) (-1/4) * (x^2e^(-4x) - 2(-1/4)e^(-4x))

Finally, simplifying the expression, we obtain:

y2(x) = xe^(-x) (1/4) * (x^2e^(-4x) + (1/2)e^(-4x))

This can be further simplified as:

y2(x) = (1/4) * x^3e^(-5x) + (1/8) * xe^(-5x)

Therefore, the second solution is y2(x) = e^(-2x) (Option C).

By using the concept of maxima,  it can be  determined that

Classification is local maxima

What is maxima of a function?

Maxima of a function gives the maximum value of a function in a given interval or within the whole domain.

f(x, y) = \(y\sqrt{x} -y^2 -3x + 11y\)

\(f_x(x, y) = \frac{y}{2\sqrt{x}} - 3\)

\(f_y(x, y) = \sqrt{x} - 2y +11\)

Putting x = 0 in \(f_y(x, y) = 0\),

-2y + 11 = 0

\(y = \frac{11}{2}\)

\((0, \frac{11}{2})\) is a critical point

Putting \(f_x(x, y) = 0\) and \(f_y(x, y) = 0\)

\(\frac{y}{2\sqrt{x}} - 3 = 0\\\frac{y}{2\sqrt{x}} = 3\\y = 6\sqrt{x}\)

\(\sqrt{x} - 2y+11 = 0\\\sqrt{x} -2\times 6\sqrt{x}+11=0\\\sqrt{x}-12\sqrt{x} + 11 = 0\\11\sqrt{x} = 11\\\sqrt{x} = \frac{11}{11}\\\sqrt{x} = 1\\x = 1\)

When x = 1, y = \(6 \times \sqrt{1} = 6\)

(1, 6) is a critical point

\(f_{xx}(x, y) = -\frac{1}{4}x^{-\frac{3}{2}}\)

\(f_{yy} = -2\)

\(f_{xy} = \frac{1}{2\sqrt{x}}\)

The point (0, \(\frac{11}{2}\)) is undefined in the second order partial derivative

For the critical point (1, 6)

\(f_{xx}(1, 6) = -\frac{1}{4}\\f_{yy}(1, 6) = -2\\f_{xy}(1, 6) = \frac{1}{2}\)

\(f_{xx}f_{yy}-(f_{xy})^2\)

\(-\frac{1}{4}\times -2-(\frac{1}{2})^2\\\frac{1}{2} - \frac{1}{4}\\\frac{1}{4} > 0\)

\(f_{yy} = -2 < 0\)

Hence (1, 6) is a point of local maxima

So it can be  determined that

\(f_x(x, y) = \frac{y}{2\sqrt{x}} - 3\)

\(f_y(x, y) = \sqrt{x} - 2y +11\)

\(f_{xx}(x, y) = -\frac{1}{4}x^{-\frac{3}{2}}\)

\(f_{yy} = -2\)

\(f_{xy} = \frac{1}{2\sqrt{x}}\)

Critical point with the smallest x - coordinate

As X and Y are two numerical variables. Because they are independent so there is no relationship between the two variables other than the linear relationship described by the regression equation. The correct answer is B. III only, that is  X and Yare independent.

When performing a regression analysis involving two numerical variables, we assume that X and Y are independent, meaning that the value of one variable does not depend on the value of the other variable. However, we do not assume that the variances of X and Y are equal or that the variation around the line of regression is the same for each X value. These assumptions are not necessary for performing a regression analysis. Violation of this assumption can lead to spurious results and incorrect inferences. So, the correct option in  B. III only.

Find the first derivative for each of the following:


y = 3x2 + 5x + 10
y = 100200x + 7x
y = ln(9x4)

Answers

The first derivatives for the given functions are:

For \(y = 3x^2 + 5x + 10,\) the first derivative is dy/dx = 6x + 5.

For  \(y = 100200x + 7x,\) the first derivative is dy/dx = 100207.

For \(y = ln(9x^4),\) the first derivative is dy/dx = 4/x.

To find the first derivative for each of the given functions, we'll use the power rule, constant rule, and chain rule as needed.

For the function\(y = 3x^2 + 5x + 10:\)

Taking the derivative term by term:

\(d/dx (3x^2) = 6x\)

d/dx (5x) = 5

d/dx (10) = 0

Therefore, the first derivative is:

dy/dx = 6x + 5

For the function y = 100200x + 7x:

Taking the derivative term by term:

d/dx (100200x) = 100200

d/dx (7x) = 7

Therefore, the first derivative is:

dy/dx = 100200 + 7 = 100207

For the function \(y = ln(9x^4):\)

Using the chain rule, the derivative of ln(u) is du/dx divided by u:

dy/dx = (1/u) \(\times\) du/dx

Let's differentiate the function using the chain rule:

\(u = 9x^4\)

\(du/dx = d/dx (9x^4) = 36x^3\)

Now, substitute the values back into the derivative formula:

\(dy/dx = (1/u) \times du/dx = (1/(9x^4)) \times (36x^3) = 36x^3 / (9x^4) = 4/x\)

Therefore, the first derivative is:

dy/dx = 4/x

To summarize:

For \(y = 3x^2 + 5x + 10,\) the first derivative is dy/dx = 6x + 5.

For y = 100200x + 7x, the first derivative is dy/dx = 100207.

For\(y = ln(9x^4),\) the first derivative is dy/dx = 4/x.
