Then the ratio of corresponding sides will be equal:

Find missing sides by using the ratio:

The inequality 4/3|1/4x+3|<4 are Ox>-13 and x < -11 or Ox<-24 and x > 0

We can begin by isolating the absolute value on one side of the inequality:

4/3|1/4x+3|<4

|1/4x+3|<3/2

We can then split this inequality into two cases, one for when 1/4x+3 is positive and one for when it is negative:

1/4x+3>0: 1/4x+3>3/2, so multiplying both sides by 4, we get x>-13 and x<-11

1/4x+3<0: 1/4x+3<-3/2, so multiplying both sides by -4, we get x<-24 and x>0

So, the solution is: Ox>-13 and x < -11 or Ox<-24 and x > 0

The different percentages are, 42%, 21% and 63%.

What is the percentage?

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The word "percent" is used to symbolize it.

There is no dimension to percentages. As a result, it is known as a dimensionless number. We must divide the value by the entire value to find the percentage, and then multiply the resulting number by 100.

Now, according to the given information, the double number line shows that 42 people watched Deon's new video today.

Now, we are to find,

100% of 42 people.

This is, (100/100)*42 = 42%.

Again, 50% of 42 people is,

(50/100)*42 = 21%.

Again, 150% of 42 people is,

(150/100)*42 = 63%.

Hence, the percentages are, 42%, 21% and 63%.

The quadratic equation x^2 + 2x - 35 = 0 represents the solutions x = -7 and 5.

To find the quadratic equation with the given solutions of x = -7 and 5, we can start by using the fact that the solutions of a quadratic equation can be written in the form:

(x - x1)(x - x2) = 0,

where x1 and x2 are the solutions. Substituting the given solutions, we have:

(x - (-7))(x - 5) = 0,

which simplifies to:

(x + 7)(x - 5) = 0.

Expanding this expression gives us the quadratic equation:

x^2 + 7x - 5x - 35 = 0,

x^2 + 2x - 35 = 0.

Therefore, the quadratic equation that represents the given solutions of x = -7 and 5 is x^2 + 2x - 35 = 0.

To confirm that this equation indeed has the given solutions, we can solve it. Using the quadratic formula, which states that for a quadratic equation ax^2 + bx + c = 0, the solutions are given by:

x = (-b ± √(b^2 - 4ac)) / (2a).

For our equation x^2 + 2x - 35 = 0, a = 1, b = 2, and c = -35. Plugging these values into the formula, we get:

x = (-2 ± √(2^2 - 4(1)(-35))) / (2(1)),

x = (-2 ± √(4 + 140)) / 2,

x = (-2 ± √144) / 2,

x = (-2 ± 12) / 2.

This simplifies to x = 5 or x = -7, which are the given solutions.

Answer:

Step-by-step explanation:

They're congruent.

The value of cosh (i4π​ ) A. 1.414214 or ∠270°.

The complex number equivalent to tan h ( 4π​ ) is D. 0.70717∠0°.

The value of sin h (5+5j) D. 19.14 −j86.11.

2. The hyperbolic cosine function, cosh(z), is defined

as\((e^z + e^{(-z))\)/2.

Substituting z = i x 4π:

So, cosh(i 4π) = \((e^{(i 4\pi)} + e^{(-i 4\pi)})\)/2.

Using Euler's formula, \(e^{(ix)\) = cos(x) + i sin(x):

cosh(4πi) = (cos(4π) + i sin(4π) + cos(-4π) + i sin(-4π))/2.

cosh(4πi) = (1 + i x 0 + 1 + ix 0)/2 = 2/2 = 1.

Therefore, the answer is A. 1.414214 or ∠270°.

9.The hyperbolic tangent function, tanh(z), is defined as

\((e^z + e^{(-z))\)/(\((e^z + e^{(-z))\).

Substituting z = 4π:

tanh(4π) = \((e^{(4\pi)} - e^{(-4\pi))}/(e^{(4\pi)} + e^{(-4\pi)).\)

Since \(e^{(ix)\)= cos(x) + i sin(x):

So, tanh(4π) = (cos(4π) + i sin(4π) - cos(-4π) - i sin(-4π))/(cos(4π) + i sin(4π) + cos(-4π) + i sin(-4π)).

Simplifying cos(4π) = 1 and sin(4π) = 0:

tanh(4π) = (1 + i x 0 - 1 - i x 0)/(1 + i x 0 + 1 + i x 0) = 0/2 = 0.

Therefore, the answer is D. 0.70717∠0°.

3.  The hyperbolic sine function, sinh(z), is defined as \((e^z - e^{(-z))\)/2.

  Substituting z = 5 + 5j:

  sinh(5+5j) = (\(e^{(5+5j)} - e^{(-(5+5j))\))/2.

  sinh(5+5j) =\((e^5 e^{(5j)} - e^5 e^{(-5j)\))/2.

Using Euler's formula, \(e^{(ix)\) = cos(x) + i sin(x):

sinh(5+5j) = (\(e^5\) (cos(5) + i sin(5)) - \(e^5\) (cos(-5) + i sin(-5)))/2.

Simplifying cos(5) and sin(5) gives real and imaginary parts:

sinh(5+5j) = (\(e^5\)  cos(5) - \(e^5\) cos(5) + i(\(e^5\) sin(5) - \(e^5\) sin(-5)))/2.

sinh(5+5j) = i\(e^5\) sin(5).

CORRECT ANSWER 42 degrees = Angle A

explanation-

When solving for a triangle, regardless of shape, the angles will always have to add up to 180 degrees. We are given that the angle at the top (let's call it C) is 79 degrees. 180 minus 79 is 101. This means of the two angles left, we have 101 degrees that need to be filled between angle A and the unnamed angle. We are given the variable X in order to add among our angles to try and solve them. X+48 will give us angle A and X+65 will give us the unnamed angle. However, 65 and 48 added to 79 will give us more than 180, which means our X is less than 1.

The easiest way to solve for X is to start to subtract numbers by our given.

-2 + 48 is 46 and -2 + 65 is 63. 63 plus 48 is still more than 101. So this is incorrect.

Correct answer - X = -6.  -6 + 48 is 42, and -6 + 65 is 59. 59+42 is 101.  So our angle A is 42 degrees.

From the given data, we say a definite integral is improper if one endpoint is infinite, or if the integrand is infinite.

One endpoint is infinite, or if the integrand is infinite, the definite integral cannot be evaluated using the usual techniques. Instead, we must use the concept of a limit to find the value of the integral, if it exists. In the case where one endpoint is infinite, we take a limit as a variable approaches infinity. In the case where the integrand is infinite, we may need to split the integral into pieces or use some other method to deal with the singularity.

The aim of hypothesis testing is to make inferences or conclusions about a population based on sample data. It allows us to objectively analyze the evidence provided by the data and make decisions based on that evidence. By comparing the observed data to what would be expected under a specific hypothesis, hypothesis testing helps us evaluate whether the data supports or contradicts the claim being tested.

Hypothesis testing provides a structured and systematic approach to assess the validity of a claim or hypothesis. Hypothesis testing achieves several objectives that cannot be otherwise achieved:

Objectivity: Hypothesis testing provides a framework that helps remove personal biases and subjectivity from the decision-making process. It requires formulating clear hypotheses, defining appropriate statistical tests, and following predetermined rules to reach conclusions. This objectivity ensures that decisions are based on evidence rather than personal opinions or preferences.

Quantification of uncertainty: Hypothesis testing allows us to quantify the level of uncertainty associated with the conclusions drawn from the sample data. It provides measures such as p-values and confidence intervals that indicate the likelihood of obtaining the observed results under the null hypothesis. These measures help in assessing the strength of evidence and determining the level of confidence in the conclusions made.

Generalization to the population: Hypothesis testing enables us to make inferences about the population based on the sample data. By testing a hypothesis on a representative sample, we can draw conclusions that extend beyond the observed data. This generalization provides insights and knowledge about the larger population, allowing us to make informed decisions and predictions.

Example of hypothesis testing:

Claim: A new fertilizer leads to an increase in crop yield by at least 10%.

Step 1: Formulate the null and alternative hypotheses:

Null hypothesis (H0): The new fertilizer has no effect on crop yield or increases it by less than 10%.

Alternative hypothesis (Ha): The new fertilizer increases crop yield by at least 10%.

Step 2: Set the significance level (alpha):

Determine the desired level of significance to make a decision. Let's assume alpha = 0.05.

Step 3: Collect and analyze the data:

Implement the new fertilizer on a sample of crops.

Measure the crop yield for each sample plot and calculate the sample mean.

Step 4: Conduct the hypothesis test:

Use an appropriate statistical test, such as a one-sample t-test, to compare the sample mean to the hypothesized value of 10% increase.

Calculate the test statistic and the corresponding p-value.

Step 5: Make a decision and interpret the results:

If the p-value is less than the significance level (alpha), reject the null hypothesis.

Conclude that there is evidence to support the claim that the new fertilizer increases crop yield by at least 10%.

If the p-value is greater than the significance level (alpha), fail to reject the null hypothesis. Conclude that there is insufficient evidence to support the claim.

Step 6: Draw conclusions and report the findings:

Summarize the results, including the test statistic, p-value, and the decision made.

Provide interpretations and recommendations based on the findings, considering the limitations and context of the study.

Answer:

7.81 units

Step-by-step explanation:

To find the distance between two points, we can use the distance formula:

d = √((x2 - x1)^2 + (y2 - y1)^2)

where (x1, y1) and (x2, y2) are the coordinates of the two points.

Using the coordinates given in the problem, we can plug in the values into the formula:

d = √((4 - (-2))^2 + (1 - (-4))^2)

Simplifying this expression, we get:

d = √((6)^2 + (5)^2)

d = √(36 + 25)

d = √61

Therefore, the distance between the two points (-2,-4) and (4,1) is √61 (square root of 61), which is approximately 7.81 units.

It is important to know about the percentage first, the percent number is per 100. It can be determined by this formula

A% = A/100

where A is the value or the price

From the text we know that :

initial tax rate = 7.0%

final tax rate = 7.5%

item price = $200

By using percentages, we can know the tax price

Initial tax price

initial tax price = initial tax rate x item price

initial tax price = 7.0% x 200

initial tax price = 7/100 x 200

initial tax price = $14

Final tax price

final tax price = final tax rate x item price

final tax price = 7.5% x 200

final tax price = 7.5/100 x 200

final tax price = $15

The increase in sales tax = Final tax price - Initial tax price

The increase in sales tax  = $15 - $14

The increase in sales tax  = $1
