Answer:

Start with the parent function y= 1/x^2

Add 3 to x in the denominator, because the graph is shifted left 3.

Add 1 to the fraction, because the graph is shifted up 1 unit.

Step-by-step explanation:

i just know

The equation of the function shown in the provided graph is \(y=\frac{1}{(x+3)^{2} }\).

The parent function is: \(f(x)=\frac{1}{x^{2} }\)

If a function f(x) is shifted horizontally by k units the parent function f(x) becomes f(x+k) where k>0

Since the graph is shifted towards the negative x-axis by 3 units.

So, the parent function f(x) will become f(x+3).

\(f(x)=\frac{1}{x^{2} }\)

\(f(x+3)=\frac{1}{(x+3)^{2} }\)

So, the equation of the function will be \(y=\frac{1}{(x+3)^{2} }\).

Therefore, The equation of the function shown in the provided graph is \(y=\frac{1}{(x+3)^{2} }\).

The null and alternative hypotheses are:

H0: β1 = 0 (The slope is not significant.)

H1: β1 ≠ 0 (The slope is significant.)

Here,β1=0.0943seβ1=0.107α=0.05

Test the slope significance and find the t-test statistic.

We need to find the t-test statistic so that we can compare it with the t-distribution, whose distributional properties we know, to determine if we can reject or fail to reject the null hypothesis.t-test statistic is calculated by dividing the value of β1 by its standard error (seβ1) and taking the absolute value of this quotient.

t-test statistic = | β1/seβ1 | = |0.0943/0.107| = 0.881

The degrees of freedom (df) associated with this t-test are df = n - 2, where n is the sample size for the explanatory variable x.

In this problem, the decision rule and conclusion are as follows:

Decision Rule: Reject the null hypothesis if |t-test statistic| > tc where tc is the critical value obtained from the t-distribution with df degrees of freedom and a significance level of α/2 in each tail.

Conclusion: The slope is not significant if we fail to reject the null hypothesis, but the slope is significant if we reject the null hypothesis. Since the t-test statistic (0.881) is less than the critical value (1.987), we fail to reject the null hypothesis. Therefore, we conclude that the slope is not significant.

There are many different ways to portray your findings for an individual to view and understand. However, each have their pros and cons. When using a table, all of the specific numbers of your data can clearly be seen and compared with one another without having to analyze a picture. However, since there is no visual correlation that shows the growth and decline of your data, someone who best comprehends visually may not be able to understand your findings. It sis best to vary your sources of displaying information to make sure that it is all able to be understood by any viewer. When using a graph, you have a clear visual representation of the correlation of your variables in your experimentation. This allows the viewer to comprehend your data as a picture and see the change as the picture moves. However, it take further analysis and cross referencing to get specific quantitative data as you are required to read across and down the graph. And finally, when using equations you can show the direct way that the change was caused in your experiment. Each equation has a specific input and output. However, the drawback is the person viewing your data may have to solve the equations themselves to find out your data or simply be confused as equations don’t directly show data, but rather how to find it. It is important to have a varied combination of these things to allow for your data to be throughly understood by anyone viewing it. I hope this helps! :)

If consider the Pythagorean Theorem and its converse. A, C, D, and E are correct statements.

Pythagoras's theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.

In this case, statement A is correct because 6, 8, and 10 are possible side lengths for a right triangle.

Statement B is incorrect because 10, 15, and 20 are not possible side lengths for a right triangle.

Statement C is correct because the Pythagorean Theorem works only for sides of a right triangle.

Statement D is correct because if the sides of a right triangle are of lengths 8 and 15, its hypotenuse is 17.

Statement E is correct because the converse of the Pythagorean Theorem allows us to calculate the side lengths of right triangles.

Thus, the correct statements would be options A, C, D, and E.

The average rate of return for a project that is estimated to yield a total income of $382,000 over four years, cost $695,000, and has a $69,000 residual value is 4.5% .

Here's how to solve for the average rate of return:

Total income = $382,000

Residual value = $69,000

Total cost = $695,000

Total profit = Total income + Residual value - Total cost

Total profit = $382,000 + $69,000 - $695,000

Total profit = -$244,000

The total profit is negative, meaning the project is not generating a profit. We will use the negative number to find the average rate of return.

Average rate of return = Total profit / Total investment x 100

Average rate of return = -$244,000 / $695,000 x 100

Average rate of return = -0.3518 x 100

Average rate of return = -35.18%

Rounded to one decimal place, the average rate of return is 35.2%. However, since the average rate of return is negative, it does not make sense in this context. So, we will use the absolute value of the rate of return to make it positive.

The general solution is v = π/4 - arcsin(-√(3) / 2) + 2πn, where n is an integer.

To find all angles v between -π and π that satisfy the equation -√(2)*sin(v) + √(2)*cos(v) = √(3), we can manipulate the equation using trigonometric identities.

First, let's rewrite the equation in terms of the sine and cosine functions:

-√(2)*sin(v) + √(2)*cos(v) = √(3)

Next, we can simplify the left side of the equation by factoring out the common factor of √(2):

√(2) * (-sin(v) + cos(v)) = √(3)

Dividing both sides by √(2), we have:

-sin(v) + cos(v) = √(3) / √(2)

Now, let's rewrite the left side of the equation using the sine and cosine addition formula:

-√(2)*sin(v - π/4) = √(3) / √(2)

Dividing both sides by -√(2), we obtain:

sin(v - π/4) = -√(3) / 2

Now, we can find the angles v between -π and π that satisfy the equation by taking the inverse sine of both sides:

v - π/4 = arcsin(-√(3) / 2)

Since the inverse sine function has a range of -π/2 to π/2, we can add or subtract multiples of 2π to obtain all possible angles v within the given range.

The general solution is:

v = π/4 - arcsin(-√(3) / 2) + 2πn, where n is an integer.

This equation provides all the angles v between -π and π that satisfy the given equation.

The maximum performance is 74.8 and it occurs at a stress level of 11.

The model p(x) = -0.2x² + 4.4x + 31.6 is used to predict performance on a task, p, where x represents stress level.

To determine the maximum performance and the stress level at which it occurs, we need to use the formula: x = -b/2a, where a = -0.2 and b = 4.4.

The stress level at which maximum performance occurs is

x = -b/2a.

Therefore, substituting the given values for a and b into the formula,

x = -4.4/(2 x -0.2) = 11

The maximum performance is obtained by substituting x = 11 into the model p(x):

p(11) = -0.2(11)² + 4.4(11) + 31.6 = 74.8

Therefore, the maximum performance is 74.8 and it occurs at a stress level of 11.

It is true that the existence of two local maxima does not guarantee the presence of a local minimum. It is possible for a function to have multiple local maxima and no local minimum.

For example, consider the function f(x,y) = x^4 - 4x^2 + y^2. This function has two local maxima at (2,0) and (-2,0), but no local minimum. Therefore, the statement "if f(x,y) has two local maximal, then f must have a local minimum" is false. The presence or absence of local maxima and minima depends on the behavior of the function in the immediate vicinity of a point, and cannot be determined solely based on the number of local maxima. It is possible for a function to have an infinite number of local maxima and minima, or none at all. Therefore, it is important to carefully analyze the behavior of a function in order to determine the presence or absence of local extrema.

Answer:  x is 25°

The measure of arcPT is 32 degrees. The measure of arcXZ is 54°

(The drawing is not to scale!)

Step-by-step explanation:  The angle of the intersecting chords is

m∠ = (a + b)/2 .  Use 'a' for the measure of arc PT, 'b' for the measure of arc XZ

So 43 =([x+7] +[2x + 4])/2 .  Substitute the values given for a & b .  

86 = 3x +11

75 = 3x

x = 25

m∠= a = x + 7

The graphs of the functions for the two months will have the same slope but potentially different y-intercepts, representing the relationship between the number of sandwich and wrap lunch specials sold and the corresponding profit made by Sal's Sandwich Shop.

In the given problem, the equation 2x + 3y = 1,470 represents Sal's profits from lunch specials last month, where x is the number of sandwich lunch specials sold and y is the number of wrap lunch specials sold.

To answer question 5, which asks about the similarities and differences between the graphs of the functions for the two months, we need to consider the equation for the next month's profit.

If the profit on each sandwich and wrap remains the same as last month ($2 and $3 respectively), we can set up the equation to represent the profit for the next month.

Let's call it P2.

P2 = 2x + 3y

Given that the total profit for the next month is $1,593, we can write the equation as:

1,593 = 2x + 3y.

To compare the graphs of the two months, we need to analyze the coefficients of x and y in both equations.

In the equation for the previous month's profit (P1 = 2x + 3y = 1,470), the coefficient of x is 2, and the coefficient of y is 3.

In the equation for the next month's profit (P2 = 2x + 3y = 1,593), the coefficient of x is still 2, and the coefficient of y is still 3.

Therefore, the slope of both graphs remains the same: 2/3.

The y-intercept, however, may differ between the two equations, as it represents the initial profit when x and y are both 0.

Since the profit amounts are different for each month, the y-intercept for the next month's graph will likely be different from the previous month's graph.

In summary, the graphs of the functions for the two months have the same slope but potentially different y-intercepts, representing the similarities and differences in the initial profits.
