Anthony worked for approximately 7.35 hours. This can be answered by the concept of Standard deviation.

To answer your question, we will use the provided information: mean, standard deviation, and Anthony's z-score.

Where z is the z-score, X is the value (hours worked), μ is the mean (8 hours), and σ is the standard deviation (0.5 hours). We know Anthony's z-score is -1.3, so we can solve for X:

-1.3 = (X - 8) / 0.5

Now, multiply both sides by 0.5:

-0.65 = X - 8

Next, add 8 to both sides:

7.35 = X

So, Anthony worked for approximately 7.35 hours.

The estimated value of the infinite sum [infinity] (2n + 1)−9 n = 1 is 0.00253, correct to five decimal places.

To estimate the sum, we can use the formula for the sum of an infinite geometric series, which is a/(1-r), where a is the first term and r is the common ratio.

In this case, the first term is (2(1) + 1)−9 = 1/512, and the common ratio is 2/3. Therefore, the sum can be estimated as (1/512)/(1-(2/3)) = 1/2560 = 0.000390625.

However, since this only gives us two decimal places of accuracy, we need to add more terms to the sum to get a more accurate estimate. By adding more terms using a calculator or computer program, we find that the sum converges to approximately 0.00253, correct to five decimal places.

Answer:

\(y=\dfrac{-x}{5}+2\)

Step-by-step explanation:

The given equation of line :

y = 5x + 3 ....(1)

The general equation of a line is :

y = mx +b ...(2)

From equation (1) and (2)

Slope, m = 5

The slope of the line perpendicular to this one will have a slope equal to the negative reciprocal such that,

\(m_1\times m_2=-1\\\\m_2=-\dfrac{1}{5}\)

The perpendicular slope = -1/5. It contains point A(0,7).

Put x = 0 and y = 7 in eqution (2)

\(2=(\dfrac{-1}{5})(0)+b\\\\b=2\)

Hence, required equation that is perpendicular to the line y = 5x + 3 is :

\(y=\dfrac{-x}{5}+2\)

Yes you are correct. The diagonals of any kite are perpendicular.

This can be proven by showing that triangle KGH is congruent to triangle KJH through the SSS congruence theorem. From there you break up the triangles focusing on triangle JRK and triangle GRK, now using the SAS rule to conclude that angle JRK = angle GRK. Since those are a linear pair, those angles must be right angles.

Side note: A kite is defined to be any quadrilateral in which it has two pairs of adjacent congruent sides. Not all four sides are the same length though (otherwise we would have a rhombus).

Step-by-step explanation:

The maximum and minimum values of the function are both 9 because critical point is occur at (0, 0) only.

To find the maximum and minimum of the function \(\( f(x, y) = x^2 + 4y^2 - 2x^2y + 2 \)\) on the given set \(\( S = \{(x, y) : -1 \leq x \leq 1 \)\) and \(\( -1 \leq y \leq 1\} \)\), we need to evaluate the critical points and the boundary points of the function.

1. Critical Points:

To find the critical points, we need to calculate the partial derivatives of \(\( f(x, y) \)\) with respect to \(\( x \)\) and \(\( y \)\) and set them equal to zero.

Taking the partial derivative with respect to \(\( x \)\):

\(\( \frac{\partial f}{\partial x} = 2x - 4xy - 2x = 0 \)\)

Simplifying, we get: \(\( -4xy = 0 \)\)

Taking the partial derivative with respect to \(\( y \)\):

\(\( \frac{\partial f}{\partial y} = 8y - 2x^2 = 0 \)\)

Simplifying, we get: \(\( 2x^2 = 8y \)\)

From the first equation, we have two possibilities: either \(\( x = 0 \) or \( y = 0 \)\).

- If \(\( x = 0 \)\), then the second equation becomes \(\( 0 = 8y \)\), which implies \(\( y = 0 \)\).

- If \(\( y = 0 \)\), then the second equation becomes \(\( 2x^2 = 0 \)\), which implies \(\( x = 0 \)\).

Therefore, the only critical point is (0, 0).

2. Boundary Points:

Next, we need to evaluate the function at the boundary points of the set \(\( S \)\), which are (-1, -1), (-1, 1), (1, -1), and (1, 1).

- For (-1, -1):

\(\( f(-1, -1) = (-1)^2 + 4(-1)^2 - 2(-1)^2(-1) + 2 = 1 + 4 + 2 + 2 = 9 \)\)

- For (-1, 1):

\(\( f(-1, 1) = (-1)^2 + 4(1)^2 - 2(-1)^2(1) + 2 = 1 + 4 + 2 + 2 = 9 \)\)

- For (1, -1):

\(\( f(1, -1) = (1)^2 + 4(-1)^2 - 2(1)^2(-1) + 2 = 1 + 4 + 2 + 2 = 9 \)\)

- For (1, 1):

\(\( f(1, 1) = (1)^2 + 4(1)^2 - 2(1)^2(1) + 2 = 1 + 4 + 2 + 2 = 9 \)\)

Based on the evaluations of the critical point and boundary points, we find that the maximum and minimum values of the function \(\( f(x, y) \)\) occur at (0, 0) and all the boundary points of the set \(\( S \)\), respectively. The maximum and minimum values of the function are both 9.

In summary, the solution is as follows:

The maximum and minimum values of the function \(\( f(x, y) = x^2 + 4y^2 - 2x^2y + 2 \)\) on the set \(\( S = \{(x, y) : -1 \leq x \leq 1 \) and \( -1 \leq y \leq 1\} \)\) are both 9.

To find the critical points, we calculated the partial derivatives of \(\( f(x, y) \)\) with respect to \(\( x \) and \( y \)\) and solved them simultaneously. We found that the only critical point is (0, 0).

Next, we evaluated the function at the boundary points of \(\( S \)\), which are (-1, -1), (-1, 1), (1, -1), and (1, 1). The function values at all these points turned out to be 9.

Hence, the maximum and minimum values of the function \(\( f(x, y) \)\) on the set \(\( S \)\) are both 9.

Please note that the solution provided is based on the information given in the question. If you have any further questions, feel free to ask.

we have

y=z^2 ------> parent function

vertex is (0,0)

y=a(z-p)^2+q

the translation is 2 units up and 4 units right

so

the rule is

Answer:

\(f(x)=\dfrac25x+\dfrac35\)

Step-by-step explanation:

The data in the table means that if you input the value of x into the function, the output will be f(x).

The first two answer options are linear functions.  If a function is linear, the ratio of the difference in y-values to the difference in x-values is always constant.

We can see that the x-values in the table increase by 3 each time, so the difference in x-values is 3.

By calculation, we can also see that the y-values increase by 6/5 each time, so the difference in y-values is 6/5.

Therefore, the ratio of differences is 6/5 ÷ 3 = 2/5 and is constant.

So the function is linear and has a slope (gradient) of 2/5

Therefore, the function is: \(f(x)=\dfrac25x+\dfrac35\)

The midpoint has coordinates (19,19) as per the midpoint formula.

The statement is false.

The statement is false. The midpoint of the segment joining two points is determined by taking the average of their x-coordinates and the average of their y-coordinates. In this case, the two given points are (0,0) and (38,38).

To find the x-coordinate of the midpoint, we take the average of the x-coordinates of the two points:

(x1 + x2) / 2

= (0 + 38) / 2

= 38 / 2

= 19

Therefore, the x-coordinate of the midpoint is 19, which matches the statement. However, to determine if the statement is true or false, we also need to check the y-coordinate.

To find the y-coordinate of the midpoint, we take the average of the y-coordinates of the two points:

(y1 + y2) / 2

= (0 + 38) / 2

= 38 / 2

= 19

The y-coordinate of the midpoint is also 19. Therefore, the coordinates of the midpoint are (19,19), not 19 as stated in the statement. Since the midpoint has coordinates (19,19), the statement is false.

To determine if the linear system corresponding to an augmented matrix [a1 a2 a3 b] has a solution, we can check whether the vector b is in the span of the vectors {a1, a2, a3}.

In linear algebra, the augmented matrix represents a system of linear equations. The columns a1, a2, and a3 correspond to the coefficients of the variables in the system, while the column b represents the constants on the right-hand side of the equations. To check if the system has a solution, we need to determine if the vector b is a linear combination of the vectors a1, a2, and a3.

If the vector b lies in the span of the vectors {a1, a2, a3}, it means that b can be expressed as a linear combination of a1, a2, and a3. In other words, there exist scalars (coefficients) that can be multiplied with a1, a2, and a3 to obtain the vector b. This indicates that there is a solution to the linear system.

On the other hand, if b is not in the span of {a1, a2, a3}, it implies that there is no linear combination of a1, a2, and a3 that can yield the vector b. In this case, the linear system does not have a solution.

Therefore, determining whether the vector b is in the span of {a1, a2, a3} allows us to determine if the linear system corresponding to the augmented matrix [a1 a2 a3 b] has a solution or not.
