The addition and subtraction rule with significant figures: Round the result to the same decimal place as the measurement with the fewest decimal places.

What is the rule for determining significant figures in addition and subtraction?

When performing addition or subtraction calculations with measurements, it is important to consider the number of decimal places in the numbers involved.

The rule states that the result of the calculation should be rounded to the same decimal place as the measurement with the fewest decimal places.

For example, let's consider the addition of 53.5 and 46.5. The measurement with the fewest decimal places is 46.5, which has one decimal place.

Therefore, the result of the addition should also be rounded to one decimal place, giving us 100.0.

In this case, the sum of 53.5 and 46.5 would have three significant figures, as it is determined by the measurement with the fewest significant figures (46.5) which has three significant figures.

By applying the addition and subtraction rule with significant figures, we ensure that the precision of the result aligns with the least precise measurement involved in the calculation.

Let us first understand what the y-axis is and what a coordinate plane is. A coordinate plane is a two-dimensional plane formed by the intersection of a vertical line and a horizontal line at a point called the origin. The vertical line is the y-axis, while the horizontal line is the x-axis. These axes are numbered by counting the units.

A point is represented in the coordinate plane as an ordered pair (x,y), where x is the coordinate on the x-axis, and y is the coordinate on the y-axis. In the given answer choices, (-3,4) and (5,-2) are on the far left and right sides of the coordinate plane, respectively. (-5,3) and (4,5) are in the middle. The point nearest to the y-axis is (-3,4), which is located closest to the y-axis. Therefore, (-3,4) is the answer. Hence, the answer is (-3,4).

To find the standard deviation of a sampling distribution, you need to calculate the mean, deviations, squared deviations, and sum of squared deviations, and then divide by n-1 before taking the square root.

To find the standard deviation of a sampling distribution, you can follow these steps:

1. Collect a sample of data from the population of interest.
2. Calculate the mean of the sample.
3. Calculate the deviation of each individual data point from the mean.
4. Square each deviation.
5. Sum up all the squared deviations.
6. Divide the sum of squared deviations by the sample size minus one (n-1).
7. Take the square root of the result obtained in step 6.

The standard deviation of the sampling distribution represents the average amount by which the sample means differ from the population mean. It measures the variability or dispersion of the sample means around the population mean.

Let's consider an example: Suppose you want to find the standard deviation of the sampling distribution of the sample means for the weights of apples. You collect a sample of 10 apples and find their weights. You calculate the mean weight of the sample, then calculate the deviation of each apple's weight from the mean, square each deviation, sum up the squared deviations, divide by 10-1, and finally, take the square root. This will give you the standard deviation of the sampling distribution.

For the angle θ in standard position, with the point (3, -2) on the terminal side, the exact values of the trigonometric functions are: sin θ = -2/√13, cos θ = 3/√13, tan θ = -2/3, csc θ = -√13/2, sec θ = √13/3, cot θ = -3/2.

To find the exact values of the six trigonometric functions (sine, cosine, tangent, cosecant, secant, and cotangent) of angle θ in standard position, given that the point (3, -2) is on the terminal side, we can use the following steps:

Determine the length of the hypotenuse (r) using the distance formula:

r = sqrt(x^2 + y^2) = sqrt(3^2 + (-2)^2) = sqrt(9 + 4) = sqrt(13)

Identify the signs of the coordinates in the given point to determine the quadrant in which the terminal side lies.

Since x = 3 is positive and y = -2 is negative, the terminal side lies in the 4th quadrant.

Calculate the values of the trigonometric functions based on the coordinates:

sine (sin θ) = y/r = -2/sqrt(13)

cosine (cos θ) = x/r = 3/sqrt(13)

tangent (tan θ) = y/x = -2/3

cosecant (csc θ) = 1/sin θ = -sqrt(13)/2

secant (sec θ) = 1/cos θ = sqrt(13)/3

cotangent (cot θ) = 1/tan θ = -3/2

Therefore, the exact values of the six trigonometric functions for angle θ with the point (3, -2) on the terminal side are:

sin θ = -2/sqrt(13)

cos θ = 3/sqrt(13)

tan θ = -2/3

csc θ = -sqrt(13)/2

The exact value of cos(-510°) is approximately -0.866. The reference angle for -510° is 150°.

To find the exact value of the expression cos(-510°), we can use the periodicity property of the cosine function. The cosine function has a period of 360°, which means that cos(x) = cos(x + 360°) for any angle x. Therefore, we can find an equivalent angle within one full revolution (360°) that has the same cosine value.

To find an equivalent angle within one full revolution, we add or subtract multiples of 360° to the given angle -510° until we get an angle within the range of 0° to 360°:

-510° + 360° = -150° (Equivalent angle within one full revolution)

Now, we need to find the cosine of the equivalent angle, which is -150°:

cos(-150°)

The cosine function of -150° can be found using a trigonometric identity:

cos(-θ) = cos(θ)

So, cos(-150°) = cos(150°)

We can use a unit circle or a calculator to find the cosine of 150°. On a unit circle, the cosine of an angle is the x-coordinate of the point where the terminal side of the angle intersects the unit circle.

On the unit circle, the point corresponding to 150° is:

( cos(150°), sin(150°) )

To find cos(150°), we look at the x-coordinate:

cos(150°) ≈ -0.866

Therefore, the exact value of cos(-510°) is approximately -0.866.

Reference angle or coterminal angle for -510°:

The reference angle is the positive acute angle between the terminal side of an angle and the x-axis. To find the reference angle for -510°, we take the positive equivalent angle within one full revolution, which is 150°. The reference angle for -510° is 150°.

Since -510° is already its terminal side, it is also a coterminal angle with itself. Another coterminal angle can be obtained by adding or subtracting multiples of 360°:

-510° + 360° = -150° (positive coterminal angle)

-510° + 720° = 210° (positive coterminal angle)

So, the reference angle for -510° is 150°, and the positive coterminal angles are 150°, -150°, and 210°.

To find the relative maxima and minima of the function f(x, y) = x^2 + xy + y^2 + 4x + 5y, we need to find the critical points by taking the partial derivatives with respect to x and y and setting them equal to zero.

∂f/∂x = 2x + y + 4 = 0 ...(1)

∂f/∂y = x + 2y + 5 = 0 ...(2)

Solving equations (1) and (2) simultaneously, we get:

x = -3

y = -1

To determine whether these critical points are relative maxima or minima, we need to evaluate the second partial derivatives. Calculate ∂^2f/∂x^2, ∂^2f/∂y^2, and ∂^2f/∂x∂y at the critical point (-3, -1).

∂^2f/∂x^2 = 2 ...(3)

∂^2f/∂y^2 = 2 ...(4)

∂^2f/∂x∂y = 1 ...(5)

To determine the nature of the critical point, we use the second derivative test. Since ∂^2f/∂x^2 > 0 and (∂^2f/∂x^2)(∂^2f/∂y^2) - (∂^2f/∂x∂y)^2 = 2*2 - 1^2 > 0, the critical point (-3, -1) is a relative minimum.

The function f(x, y) = x^2 - 3y^2 has only one critical point at (0, 0). To determine the type of the critical point, we use the second derivative test

∂^2f/∂x^2 = 2 ...(6)

∂^2f/∂y^2 = -6 ...(7)

∂^2f/∂x∂y = 0 ...(8)

At the critical point (0, 0), we have ∂^2f/∂x^2 > 0 and (∂^2f/∂x^2)(∂^2f/∂y^2) - (∂^2f/∂x∂y)^2 = 2*(-6) - 0^2 < 0. This indicates that the critical point (0, 0) is a saddle point.

The production capacity function is given as Y(K, L) = 2K^0.25L^0.75. To find the marginal product of labor (∂Y/∂L), we differentiate Y(K, L) with respect to L while treating K as a constant.

∂Y/∂L = 0.752K^0.25L^(0.75-1) = 1.5K^0.25L^-0.25

Given that the company hires 16 workers and rents a capital of $810,000, we can substitute these values into the derivative:

∂Y/∂L = 1.5*(810,000)^0.25*(16)^-0.25

For the given (s + 2)² - s² is equal to 4s + 4.

To understand why (s + 2)² - s² is equal to 4s + 4, we can use the concept of expanding and simplifying the given expression.

Starting with (s + 2)², this represents the square of the binomial (s + 2). When we expand this expression, we apply the distributive property and multiply each term in the binomial by itself:

(s + 2)² = (s + 2) * (s + 2) = s * s + 2 * s + 2 * s + 2 * 2

= s² + 2s + 2s + 4

= s² + 4s + 4

Now, let's simplify the expression by subtracting s² from (s + 2)²:

(s + 2)² - s² = (s² + 4s + 4) - s²

When we subtract s² from s², it cancels out:

(s² + 4s + 4) - s² = 4s + 4

f(x) = x + 4 and g(x) = 2x + 5,

we need to find the following functions: (f∘g)(x),  (g∘f)(x),  (f∘g)(1) and  (g∘f)

1)Now, we will calculate each part one by one: (f∘g)(x) = f(g(x)) = f(2x + 5).

Putting g(x) in place of x in f(x), we getf(g(x)) = g(x) + 4 = (2x + 5) + 4 = 2x + 9.

Therefore, (f∘g)(x) = 2x + 9

(g∘f)(x) = g(f(x)) = g(x + 4). Putting f(x) in place of x in g(x), we get g(f(x)) = 2(x + 4) + 5 = 2x + 8 + 5 = 2x + 13. Therefore, (g∘f)(x) = 2x + 13.

Now, we will find (f∘g)(1) and (g∘f)(1). (f∘g)(1) = f(g(1)) = f(2.1 + 5) = f(7).

Putting 7 in f(x), we get f(7) = 7 + 4 = 11. Therefore, (f∘g)(1) = 11(g∘f)(1) = g(f(1)) = g(1 + 4) = g(5).

To determine the values of A, B, and C, we can use the method of partial fraction decomposition.

We start by multiplying both sides of the equation by the common denominator, [tex]\((x+3)(x^2+5)\)[/tex], to eliminate the denominators:

Now, we can collect like terms and equate the coefficients of corresponding powers of x:

[tex]\[(1A + B)x^2 + (3B)x + (5A + 3C) = 6\][/tex]

Since the left side has no x term or constant term, we can set the coefficients of those terms on the right side equal to zero:

The condition for the given system to be consistent is k ≠ 0. If k is equal to zero, the system would be inconsistent, and the planes represented by the equations would not intersect.

To determine the value of k for which the given system is consistent, we need to analyze the equations and find any conditions that would lead to an inconsistent system.

The given system of equations is:

6x - 6y + 5z = 5 ...(1)

-6x + 26y + kz = -8 ...(2)

6x + 4y + 5z = 6 ...(3)

To ensure consistency, the equations should not contradict each other. This means that the three planes represented by the equations should intersect at a common point or lie on the same plane.

Let's examine the equations to identify any conditions:

Looking at equations (1) and (3), we can observe that they are not multiples of each other. Therefore, they represent two distinct planes.

Now, let's compare equations (1) and (2). To make these two equations dependent (or representing the same plane), we need the direction ratios (coefficients of x, y, and z) to be proportional. In particular, the ratio of coefficients for x, y, and z in equation (1) to equation (2) should be the same.

Comparing the ratios of the coefficients:

6/-6 = -6/26 = 5/k

Simplifying the equation:

-1 = -1/13k

To satisfy this equation, k must not be equal to zero (k ≠ 0). Otherwise, the system would become inconsistent, and the planes represented by the equations would not intersect.

The point representing the solution to the equation f(x) = g(x) is (1, 2)

To find the value of x for which f(x) = 0, we can set the function equal to zero and solve for x:

3 x - 1 = 0

Add 1 to both sides:

3 x = 1

Divide both sides by 3:

x = [tex]\dfrac{1}{3}[/tex]

Therefore, the value of x for which f(x) = 0 is x = [tex]\dfrac{1}{3}[/tex].

(b) To determine the values of x for which f(x) > 0, we need to find the intervals where the function has positive values. We can analyze the sign of f(x) by considering the sign of the coefficient of x, which is 3 in this case.

Since the coefficient is positive, f(x) will be greater than 0 when x is in the interval where x >[tex]\dfrac{1}{3}\\[/tex]

Therefore, the values of x for which f(x) > 0 are x >[tex]\dfrac{1}{3}[/tex] or in interval notation

(c) To find the value of x for which f(x) = g(x), we can equate the two functions and solve for x:

(3 x - 1) =(-2 x) + 4

Add 2 x and 1 to both sides:

5 x = 5

Dividing both sides by 5:

x = 1

Therefore, the value of x for which f(x) = g(x) is x = 1.

(d) To determine the values of x for which f(x) ≤ g(x), we need to find the intervals where the function f(x) is less than or equal to g(x). We can compare the coefficients of x in both functions to analyze the sign.

Since the coefficient of x in f(x) is positive (3) and the coefficient of x in g(x) is negative (-2), f(x) will be less than or equal to g(x) when x is in the interval where x ≤ 1.

To find the solution to the equation f(x) = g(x), we need to equate the two functions and solve for x:

3 x - 1 = -2 x + 4

Adding 2 x and 1 to both sides:

(b) The values of x for which f(x) is greater than 0 can be represented in interval notation as (1/3, infinity).

(c) The value of x for which f(x) equals g(x) is x = 1.

(d) The values of x for which f(x) is less than or equal to g(x) can be represented in interval notation as (-infinity, 1].

(e) Value of x into either f(x) or g(x) will give us the corresponding y-value.

(a) To find the value of x for which f(x) equals 0, we can set f(x) equal to 0 and solve for x. The equation is f(x) = 3x - 1 = 0.

Adding 1 to both sides of the equation gives us 3x = 1.

Next, we divide both sides of the equation by 3 to isolate x:

x = 1/3.

Therefore, the value of x for which f(x) equals 0 is x = 1/3.

(b) To determine the values of x for which f(x) is greater than 0, we need to find the x-values that make f(x) positive.

Since f(x) = 3x - 1, we want to find the x-values that make 3x - 1 greater than 0.

Setting 3x - 1 > 0 and solving for x, we have:

3x > 1,
x > 1/3.

Therefore, the values of x for which f(x) is greater than 0 can be represented in interval notation as (1/3, infinity).

(c) To find the value of x for which f(x) equals g(x), we set the two functions equal to each other:

3x - 1 = -2x + 4.

Adding 2x to both sides and adding 1 to both sides gives us:

5x = 5.

Dividing both sides of the equation by 5 gives us:

x = 1.

Therefore, the value of x for which f(x) equals g(x) is x = 1.

(d) To determine the values of x for which f(x) is less than or equal to g(x), we need to find the x-values that make f(x) less than or equal to g(x).

Setting 3x - 1 ≤ -2x + 4 and solving for x, we have:

5x ≤ 5,
x ≤ 1.

Therefore, the values of x for which f(x) is less than or equal to g(x) can be represented in interval notation as (-infinity, 1].

In this case, the sample variance is approximately 22.39.Therefore, the range is 19, the interquartile range is 5, and the sample variance is 22.39.

The range of a data set is the difference between the maximum and minimum values. The interquartile range measures the spread of the middle 50% of the data. The sample variance quantifies the variability of the data points around the mean.

To calculate the range, we find the difference between the maximum and minimum values in the data set. In this case, the maximum value is 34 and the minimum value is 15. Therefore, the range is 34 - 15 = 19.

To calculate the interquartile range (IQR), we need to find the values of the first quartile (Q1) and the third quartile (Q3). The first step is to arrange the data set in ascending order: 15, 24, 24, 25, 26, 28, 30, 34. Q1 is the median of the lower half of the data set, which is (24 + 24)/2 = 24. Q3 is the median of the upper half of the data set, which is (28 + 30)/2 = 29. The interquartile range is calculated as Q3 - Q1, so it is 29 - 24 = 5.

The sample variance measures the average squared deviation of each data point from the mean. First, calculate the mean of the data set: (15 + 24 + 24 + 25 + 26 + 28 + 30 + 34)/8 = 25.75. Then, for each data point, subtract the mean, square the result, and sum up the squared values.

The p-value of a coefficient measures the probability the null hypothesis is true in a regression model.

In a regression model, the p-value of a coefficient measures the probability of observing a coefficient as extreme as the one estimated in the model, assuming the null hypothesis is true. In other words, it quantifies the evidence against the null hypothesis.

More specifically, the null hypothesis in the context of a regression model states that there is no relationship between the independent variable (predictor) and the dependent variable (outcome). The p-value of a coefficient indicates the likelihood of observing the coefficient's value, or a more extreme value, if the null hypothesis is true.

If the p-value is small (typically below a predetermined significance level, such as 0.05), it suggests strong evidence against the null hypothesis. In this case, we reject the null hypothesis and conclude that there is a significant relationship between the independent variable and the dependent variable.

On the other hand, if the p-value is large (above the significance level), it indicates weak evidence against the null hypothesis. In this situation, we fail to reject the null hypothesis and conclude that there is insufficient evidence to support a significant relationship between the independent variable and the dependent variable.

Regarding the width of the coefficient confidence interval, it is not directly related to the p-value. The confidence interval provides a range of values within which we believe the true population value of the coefficient lies with a certain level of confidence (commonly 95% confidence interval). It is a measure of the precision of the coefficient estimate and is influenced by the variability of the data.

To summarize, the p-value measures the probability that the null hypothesis is true, and it helps us determine the statistical significance of the coefficient estimate. The coefficient confidence interval, on the other hand, provides a range of plausible values for the true coefficient and is unrelated to the p-value.

To sketch an angle θ in a standing position such that it has the least possible positive measure and the point (-2,4) is on the terminal side, we can use the following steps:

1. Plot the point (-2,4) on the coordinate plane. This point represents the terminal side of the angle θ.

2. Draw a line from the origin (0,0) to the point (-2,4). This line represents the initial side of the angle θ.

3. Measure the angle formed by the initial side and the positive x-axis. Since we want the angle to have the least possible positive measure, the angle will be in the first quadrant.

4. Use the Pythagorean theorem to find the length of the hypotenuse of the right triangle formed by the point (-2,4) and the x-axis. The hypotenuse can be found by finding the square root of the sum of the squares of the coordinates. In this case, the hypotenuse will be √((-2)^2 + 4^2) = √(4 + 16) = √20.

5. Now that we have the lengths of the sides of the right triangle, we can find the values of the trigonometric functions. Here are the six trigonometric functions of angle θ:

  - Sine (sin): sin(θ) = opposite/hypotenuse = 4/√20 = (4/√20) * (√20/√20) = 4√20/20 = √20/5
  - Cosine (cos): cos(θ) = adjacent/hypotenuse = -2/√20 = (-2/√20) * (√20/√20) = -2√20/20 = -√20/5
  - Tangent (tan): tan(θ) = opposite/adjacent = 4/-2 = -2
  - Cosecant (csc): csc(θ) = 1/sin(θ) = 1/(√20/5) = 5/√20 = (5/√20) * (√20/√20) = 5√20/20 = √20/4
  - Secant (sec): sec(θ) = 1/cos(θ) = 1/(-√20/5) = -5/√20 = (-5/√20) * (√20/√20) = -5√20/20 = -√20/4

The dimensions of the rectangular pool are: Width = 9 feet, Length = 37 feet and The dimensions of the rectangular garden are: Width = 13 feet, Length = 39 feet.

Let's solve the two problems one by one:

Rectangular Pool:

Let's assume the width of the pool is "w" feet.

According to the given information, the length of the pool is 1 foot more than four times its width, which can be expressed as:

Length = 4w + 1

The perimeter of a rectangle is given by the formula: Perimeter = 2(length + width)

In this case, the perimeter is given as 92 feet:

92 = 2(4w + 1 + w)

Now, we can solve this equation to find the width of the pool:

92 = 2(5w + 1)

92 = 10w + 2

10w = 92 - 2

10w = 90

w = 90/10

w = 9

Substituting the value of width (w) back into the expression for the length:

Length = 4w + 1

Length = 4(9) + 1

Length = 36 + 1

Length = 37

Therefore, the dimensions of the rectangular pool are:

Width = 9 feet

Length = 37 feet

Rectangular Garden:

Let's assume the width of the garden is "w" feet.

According to the given information, the length of the garden is three times its width, which can be expressed as:

Length = 3w

The perimeter of a rectangle is given by the formula: Perimeter = 2(length + width)

In this case, the perimeter is given as 104 feet:

104 = 2(3w + w)

Now, we can solve this equation to find the width of the garden:

104 = 2(4w)

104 = 8w

w = 104/8

w = 13

Substituting the value of width (w) back into the expression for the length:

Length = 3w

Length = 3(13)

Length = 39

Therefore, the dimensions of the rectangular garden are:

Width = 13 feet

Length = 39 feet

The equation of the circle is \( (x + 5)^2 + (y - 5)^2 = 5^2 \).

To find the equation of the circle, we need to determine the coordinates of its center. Since the center lies in the second quadrant, it has negative x and positive y coordinates. Let's assume the center of the circle is \((x_0, y_0)\).

Since the circle is tangent to the x-axis, the distance from the center to the x-axis is equal to the radius, which is 5. Therefore, \(y_0 = 5\).

Similarly, since the circle is tangent to the y-axis, the distance from the center to the y-axis is also equal to the radius, which is 5. Therefore, \(-x_0 = 5\) or \(x_0 = -5\).

Now we have the coordinates of the center as \((-5, 5)\) and the radius as 5. Using the formula for the equation of a circle \((x - x_0)^2 + (y - y_0)^2 = r^2\), we substitute the values to get \( (x + 5)^2 + (y - 5)^2 = 5^2 \).

Yes, the function f(x) = (x - 7)/(x + 4) has an inverse function. The inverse function is f^(-1)(x) = (4x + 7)/(1 - x), with the restriction that x is not equal to 1.

To find the inverse function, we can interchange the roles of x and y in the original function and solve for y.

Let's start by swapping x and y in the original function:

x = (y - 7)/(y + 4)

Next, we'll solve this equation for y. To eliminate the denominator, we can multiply both sides of the equation by (y + 4):

x(y + 4) = y - 7

Expanding the left side:

xy + 4x = y - 7

Now, let's isolate the y terms on one side:

xy - y = -4x - 7

Factoring out y:

y(x - 1) = -4x - 7

Finally, we can solve for y by dividing both sides by (x - 1):

y = (-4x - 7)/(x - 1)

This gives us the inverse function f^(-1)(x) = (4x + 7)/(1 - x).

However, we need to consider the restrictions on the domain of the inverse function. In this case, we can't have x = 1, as it would result in division by zero in the inverse function. Therefore, the domain of the inverse function is x ≠ 1.

To summarize, the function f(x) = (x - 7)/(x + 4) has an inverse function f^(-1)(x) = (4x + 7)/(1 - x), with the restriction that x is not equal to 1.
