To show that d/dx (csc(x)) = −csc(x)cot(x), we will use the chain rule and the derivative of the inverse function.

The chain rule states that the derivative of a composite function is the product of the derivatives of the individual functions. The derivative of the inverse function is the reciprocal of the derivative of the original function. Here are the steps:

1. Start with the given function: d/dx (csc(x))
2. Rewrite csc(x) as 1/sin(x): d/dx (1/sin(x))
3. Use the chain rule to find the derivative: (d/dx 1)(d/dx sin(x))
4. The derivative of 1 is 0, so the first term becomes 0: (0)(d/dx sin(x))
5. The derivative of sin(x) is cos(x), so the second term becomes cos(x): (0)(cos(x))
6. Simplify the expression: 0
7. Use the derivative of the inverse function to find the derivative of 1/sin(x): -1/sin^2(x)
8. Rewrite sin^2(x) as (sin(x))(sin(x)): -1/(sin(x))(sin(x))
9. Simplify the expression by canceling out one of the sin(x) terms: -1/sin(x)
10. Rewrite 1/sin(x) as csc(x): -csc(x)
11. Rewrite -1/sin(x) as -cot(x): -cot(x)
12. Combine the two terms to get the final answer: −csc(x)cot(x)

Therefore, d/dx (csc(x)) = −csc(x)cot(x).

The asymptotes of the rational function f(x)=(5)/(3x+6) are x=-2 .

To find the asymptotes of a rational function, we need to analyze the degree of the numerator and denominator, and find the values of x that make the denominator equal to zero.

First, let's find the vertical asymptotes. Vertical asymptotes occur when the denominator of a rational function is equal to zero. In this case, the denominator is 3x+6. Setting this equal to zero, we get:

3x+6=0
3x=-6
x=-2

So, the vertical asymptote is x=-2.

Next, let's find the horizontal asymptotes. Horizontal asymptotes occur when the degree of the numerator is less than or equal to the degree of the denominator. In this case, the degree of the numerator is 0 and the degree of the denominator is 1, so there is a horizontal asymptote. To find the horizontal asymptote, we need to look at the leading coefficients of the numerator and denominator. The leading coefficient of the numerator is 5 and the leading coefficient of the denominator is 3. So, the horizontal asymptote is y=5/3.

Therefore, the asymptotes of the rational function f(x)=(5)/(3x+6) are x=-2 (vertical asymptote) and y=5/3 (horizontal asymptote).

As a result, the equation system has the following solution: x = -24/5, y = -9/5.

A mathematical assertion known as an equation is composed of a pair of expressions joined together by the equal symbol. A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of a quantity x is 7.

One of the best methods to solve the given system of equations is the elimination method.

To apply the elimination method, we need to multiply one or both equations by a suitable constant so that when we add or subtract the two equations, one of the variables is eliminated. In this case, if we multiply the first equation by 3, we get:

9x + 21y = -57

Now we can add this equation to the second equation to eliminate the x variable:

9x + 21y = -57

-3x + 4y = 12

25y = -45

Dividing both sides by 25, we get:

y = -45/25 = -9/5

Now we can substitute this value of y into one of the original equations to solve for x. Let's use the second equation:

-3x + 4y = 12

-3x + 4(-9/5) = 12

-3x - 36/5 = 12

-3x = 12 + 36/5

-3x = 72/5

x = -24/5

As a result, the following is the system of equations' solution:

x = -24/5, y = -9/5

The expressions that are equivalent to 2x - 3y = 12 are B and D.

We can modify the equation algebraically and simplify 2x - 3y = 12 to find the expressions that are equal to that number:

2x - 3y = 12

2x - 12 = 3y (subtract 12 from both sides) (subtract 12 from both sides)

(2/3)x - 4 = y (divide both sides by 3) (divide both sides by 3)

As a result, the equation can also be written as y = (2/3)x – 4.

We can now determine which expressions have the same meaning as this form:

A. y = 4 - (2/3)x

This expression is simplified to give y = (-2/3)x + 4. This isn't the same as y = (2/3)x – 4.

B. y = (2/3)x - 4

This formula already equals y = (2/3)x - 4 in terms of value.

C. 2x - 3y = -12

2x - 3y + 12 = 0 is the result of adding 12 to both sides of the equation. y = (2/3)x - 4 is not the same form as this.

D. y = (3/2)x - 6

This expression can be simplified to y = (2/3)x - 4 by doing so. The formula for this is y = (2/3)x – 4.

Hence, the formulas B and D are the same as 2x - 3y = 12.

The polynomial in factored form whose solutions are x = -3, 5/2, and -5i is 2(x + 3)(2x - 5)(x² + 25).

Given the solutions;

To have the solutions at x = -3 and x = 5/2, the polynomial must have factors of (x + 3) and (2x - 5), respectively.

Also, to have a solution at x = -5i, there must be a factor of (x+5i) and its complex conjugate (x-5i):

Hence;

(x + 3)(2x - 5)(x + 5i)(x - 5i)

Multiplying out these factors gives:

(x + 3)(2x - 5)(x + 5i)(x - 5i)

(x + 3)(2x - 5)(x² + 25)

= (2x² + x - 15)(x² + 25)

= 2x⁴ + x³ - 15x² + 50x² + 25x - 375

= 2x⁴ + x³ + 35x² + 25x - 375

So the polynomial in factored form is:

Answer:

B

Step-by-step explanation:

a. 39 work sampling observations. b. By selecting a random time and a random employee to observe. c. The 95% confidence interval for the population standard is approximately 83.56 +/- (2 * 22.83), or 37.9 to 129.2 hours per hundred beak adjustments.

a. To determine the number of work sampling observations necessary to achieve a 95% confidence level with a margin of error of +10%, we need to use the following formula:

n = (Z^2 * p * (1-p)) / E^2

Where:

n = sample size

Z = Z-score for the desired confidence level (1.96 for 95% confidence level)

p = proportion of beak adjustments estimated from preliminary investigation (0.3)

E = margin of error (0.1)

Plugging in the values:

n = (1.96^2 * 0.3 * 0.7) / 0.1^2

n = 38.15

Rounding up, we need at least 39 work sampling observations.

b. The random observations should be made by selecting a random time of day, and then selecting a random employee to observe. This should be repeated until the required number of observations has been made. This method ensures that all employees have an equal chance of being observed and that the observations are not biased towards certain times or individuals.

c. To determine the standard in hours per hundred beak adjustments, we need to use the following formula:

Standard = (Total time worked / Total number of beak adjustments) * 100

For the six employees summarized in the table:

Granny:

Standard = (82 / 164) * 100

Standard = 50 hours per hundred beak adjustments

Tweety:

Standard = (80 / 161) * 100

Standard = 49.69 hours per hundred beak adjustments

Item:

Standard = (200 / 185) * 100

Standard = 108.11 hours per hundred beak adjustments

Total:

Standard = (82 + 80 + 200 + 121 + 161 + 185) / (164 + 161 + 185) * 100

Standard = 83.56 hours per hundred beak adjustments

The calculated error is the difference between the estimated standard and the true population standard. Since we do not have the population data, we cannot calculate the error. However, we can calculate the variability in the sample data using the following formula:

Standard Error = Standard Deviation / √(n)

Where:

Standard Deviation = √((Σ(x - x-bar)^2) / (n - 1))

n = sample size

Using the data provided in the table, we can calculate the standard deviation and standard error as follows:

Standard Deviation = √(((82-73.5)^2 + (80-73.5)^2 + (200-119)^2 + (121-82.5)^2 + (161-119)^2 + (185-82.5)^2) / (6-1))

Standard Deviation = 55.88

Standard Error = 55.88 / √(6)

Standard Error = 22.83

This means that there is a 95% chance that the true population standard falls within + or - 2 standard errors of the estimated sample standard. Therefore, the 95% confidence interval for the population standard is approximately 83.56 + or - (2 * 22.83), or 37.9 to 129.2 hours per hundred beak adjustments.

The answer of another zero - polynomial function with real coefficient at 1+2i is 1-2i

The other zero of the polynomial function  with real coefficients and a zero at 1+2i is 1-2i.

This is because if a polynomial function with real coefficients has a complex zero,

then the conjugate of that zero is also a zero of the function. The conjugate of a complex number is obtained by changing the sign of the imaginary part.

Therefore, the conjugate of 1+2i is 1-2i. So, if 1+2i is a zero of the polynomial function, then 1-2i is also a zero of the function.

In summary, the other zero of the polynomial function with real coefficients and a zero at 1+2i is 1-2i.

The lengths of the two legs are 2 centimeters and 9 centimeters.

Let's call the shorter leg of the right triangle x and the other leg y. According to the given information, we can create the following equation:

x = y - 7

Since we know that the hypothenuse is 13 centimeters, we can use the Pythagorean theorem to create another equation:

x^2 + y^2 = 13^2

Substituting the first equation into the second equation, we get:

(y - 7)^2 + y^2 = 13^2

Simplifying and rearranging terms, we get:

2y^2 - 14y - 72 = 0

Using the quadratic formula, we can solve for y:

y = (14 ± √(14^2 - 4(2)(-72))) / (2(2))

y = (14 ± √484) / 4

y = (14 ± 22) / 4

y = 9 or y = -2

Since the length of a leg cannot be negative, we reject the negative solution and take y = 9 centimeters as the length of the other leg. Then, we can use the first equation to find the length of the shorter leg:

x = 9 - 7

x = 2 centimeters

Therefore, the lengths of the two legs are 2 centimeters and 9 centimeters.

The equation is true, the point (-1,6) does indeed lie on the line (-3,5).

The equation of a line is typically written in the form y = mx + b, where m is the slope and b is the y-intercept. In order to determine whether or not the point (-1,6) lies on the line (-3,5), we need to plug in the x and y values of the point into the equation of the line and see if the equation is true.

First, we need to find the slope of the line. The slope is the difference in the y values divided by the difference in the x values:

m = (5 - 6)/(-3 - (-1)) = -1/-2 = 1/2

Next, we need to find the y-intercept of the line. We can do this by plugging in one of the points and solving for b:

5 = (1/2)(-3) + b

b = 5 + (3/2) = 13/2

Now we have the equation of the line: y = (1/2)x + 13/2

Finally, we can plug in the x and y values of the point (-1,6) to see if the equation is true:

6 = (1/2)(-1) + 13/2

6 = -1/2 + 13/2
