C) f is decreasing for x<0 because f′(x)<0 for x<0. , we can conclude that the function f is decreasing for x<0 because f′(x)<0 for x<0.

The derivative of f is f′(x)=x2−a2=(x−a)(x+a).

This implies that f′(x)<0 when x<−a or x>a. From the derivative, we can deduce that f is decreasing for x<0 because f′(x)<0 for x<0.

The derivative of the function f is f′(x)=x2−a2=(x−a)(x+a), where a is a positive constant. This means that the derivative is negative when x<−a or x>a. We can use this information to determine the behavior of the function. Since the derivative is negative when x is less than zero, we can conclude that the function f is decreasing for x<0 because f′(x)<0 for x<0.

DC = 17

From the diagram shown:

DE is symmetrical to BE

DE = BE

AD = 11

BC = 17

ADE and BAE are congruent triangles because :

DE is congruent to BE and

AE is shared by both.

Also angle E is a right angle in both

This is called the SIde-Angle -Side Property (SAS)

Therefore, BC = DC = 17

Answer:

x=-4, y=-1

Step-by-step explanation:

Given the following system of equations, solve the system using elimination.

\(\left \{ {{-2x-y=9} \atop {2x-9y=1}} \right.\)

(1) - Add the equations together

\(\left\begin{array}{ccc}&-2x-y=9\\+&2x-9y=1\end{array}\right\\\\\Longrightarrow -10y=10\\\\\therefore \boxed{y=-1}\)

Notice how the x term was eliminated, hence the name for this method is "elimination."

(2) - Take the value we just found for y and plug it into either of the two equations and solve for x

\(2x-9y=1\\\\\Longrightarrow 2x-9(-1)=1\\\\\Longrightarrow 2x+9=1\\\\\Longrightarrow 2x=-8\\\\\therefore \boxed{x=-4}\)

(3) - Thus, the system is solved. When x=-4, y=-1.

If you provide the desired standard error value, I can help you calculate the corresponding population standard deviation.

The standard error is a measure of the variability or uncertainty of a sample mean. It is calculated by dividing the population standard deviation by the square root of the sample size. Therefore, if we want the standard error to be smaller, the population standard deviation should be larger.

To determine how large the population standard deviation needs to be, we need to specify a desired standard error value. Without that information, it is not possible to provide a specific answer. The relationship between the population standard deviation and the standard error is inversely proportional, so as the population standard deviation increases, the standard error decreases.

To determine if it would be unusual to randomly select 12 people and find that fewer than 5 recognize the Yummy brand name, we can use the concept of standard deviation and z-scores.

First, we need to calculate the z-score, which measures how many standard deviations an observation is from the mean. The formula for calculating the z-score is:

z = (x - μ) / σ

where

z = (5 - 9.3) / 0.99

z = -4.394

Next, we can consult a standard normal distribution table or use statistical software to find the corresponding percentile associated with the z-score. This percentile represents the probability of randomly selecting a group of 12 people with fewer than 5 recognizing the Yummy brand name.

In this case, the z-score of -4.394 corresponds to an extremely low percentile, close to 0.

The exact probability can be determined using the z-score and the standard normal distribution table.

Since the probability is extremely low, it would be considered unusual to randomly select 12 people and find that fewer than 5 recognize the Yummy brand name.

However, it's important to note that the definition of "unusual" may vary depending on the specific criteria or threshold chosen.

In statistical terms, a common threshold for defining unusual events is a significance level of 5% (or 0.05). If the probability of observing the event is lower than the significance level, it is considered unusual.

Answer: x=10°

Step-by-step explanation:

The vertical asymptote is at x = 2/3, the horizontal asymptote is y = (-2/3)x, the x-intercept is at (-13/4, 0), and the y-intercept is at (0, 39/16). The graph of rational function is shown.

To plot the rational function f(x) = (-4x - 13)/(6x - 4), we can follow these steps:

Find the vertical asymptote(s) by setting the denominator equal to zero and solving for x. In this case, 6x - 4 = 0, so x = 2/3. Therefore, there is a vertical asymptote at x = 2/3.

Find the horizontal asymptote by comparing the degrees of the numerator and denominator. Since the degree of the numerator is 1 and the degree of the denominator is also 1, the horizontal asymptote is y = (-4/6)x = (-2/3)x.

Find the x-intercept by setting the numerator equal to zero and solving for x. In this case, -4x - 13 = 0, so x = -13/4. Therefore, there is an x-intercept at (-13/4, 0).

Find the y-intercept by setting x equal to zero and evaluating the function. In this case, f(0) = (-13/4) / (-4/3) = 39/16. Therefore, there is a y-intercept at (0, 39/16).

Choose some other values of x to plot the curve of the function. For example, we can choose x = -3, -2, -1, 0, 1, 2, 3.

Using these steps, we can plot the rational function as shown.

Answer:

y = x - 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

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

with (x₁, y₁ ) = (6, 3) and (x₂, y₂ ) = (4, 1)

m = \(\frac{1-3}{4-6}\) = \(\frac{-2}{-2}\) = 1 , then

y = x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (4, 1 )

1 = 4 + c ⇒ c = 1 - 4 = - 3

y = x - 3 ← equation of line

To evaluate this line integral, we will use Green's theorem, which states that for a closed curve C, oriented counterclockwise, and a region R bounded by C, the line integral of the vector field F along C is equal to the double integral of the curl of F over R:

∮c F ⋅ dr = ∬R (curl F) ⋅ dA
In this case, our vector field F is:
F = (5y - e×sin(x)) i + (8x - sin(y³)) j
And the curl of F is:
curl F = ∂(8x - sin(y³))/∂x - ∂(5y - e*sin(x))/∂y = 5e×cos(x) + 3y²×cos(y³)
Now, we need to find the region R bounded by C, which is the circle of radius 5 centered at (3,-5). This is simply the disk with center (3,-5) and radius 5.
Using polar coordinates, we can write the double integral as:
∬R (curl F) ⋅ dA = ∫θ=0..2π ∫r=0..5 (5e×cos(θ) + 3r²×cos(r³×sin(θ)³)) r dr dθ
Evaluating this integral, we get:
∬R (curl F) ⋅ dA = π×(625e + 375)
Therefore, by Green's theorem:
∮c F ⋅ dr = π×(625e + 375)
Substituting F and evaluating the integral, we get:
∮c (5y - e×sin(x)) dx + (8x - sin(y³)) dy = π×(625e + 375)
This is the value of the line integral.

There were 240 more credit card sales than cash sales.

Step-by-step explanation:

By using the ratio 8:3 I was able to determine that if there were 144 cash sales that would mean that there would be 384 credit card sales. However, the question asks "How many more credit card sales were there than cash sales?" Meaning that we need to find the difference. 384-144= 240.

This means that there were 240 more credit card sales than cash sales.

a) The equation that fits the story is given as follows:

2x/5 = 28.

b) The length of the racetrack is given as follows: 70 meters.

c) Antonio had to go 42 meters farther to reach the finish line.

The length of the race track is obtained applying the proportions in the context of this problem.

His car stops 10m past the starting line. After he fixes a wheel, the car goes 2/5 the racetrack’s total distance and then stops for good. It is 38m from the starting line, hence the distance driven during this entire period is of:

38 - 10 - 28 m.

28 m is 2/5 of the track length, which is going to be called x, hence the equation is given as follows:

2x/5 = 28.

The track length is then obtained as follows:

2x = 5 x 28

x = 5 x 14

x = 70 meters.

Thus the remaining distance is of:

70 - 28 = 42 meters.

Given problem;

   Solve for π;

To solve for π implies that we make it the subject of the expression.

So;

       A = π r²

      Now multiply both sides by \(\frac{1}{r^{2} }\)

 So;

                A x \(\frac{1}{r^{2} }\)   = \(\pi\) x r² x \(\frac{1}{r^{2} }\)

              r² cancels out from the right side and leaves only π;

So    \(\pi = \frac{A}{r^{2} }\)
