a. The discontinuity in a function results in a vertical asymptote when the value of the function tends to infinity.

b. The discontinuity in a function results in a hole in a graph when the value at the discontinuity does not exist.

The discontinuity of a function is the value of the function at which the value of the function is not continuous.

A vertical asymptote is a vertical line such that the value of a function tends to it as its x value approaches a particular value.

A discontinuity in a function results in a vertical asymptote when the value of the function tends to infinity as the x value of the function tends to the value of the vertical asymptote.

A discontinuity in a function results in a hole in a graph when the limit of the function as the x value of the function tends to the value at the discontinuity does not exist.

By using subtraction of yellow areas from the entire squares, the areas of the inscribed shapes are listed below:

The areas of the inscribed shapes can be easily found by subtracting the yellow areas from the square, in order to find the value of green areas. Now we proceed to find the result for each case by using area formulae for triangles:

Case A

A = 6² - 0.5 · (3) · (6) - 0.5 · (3) · (6)

A = 36 - 18

A = 18 units

Case B

A = 6² - 4 · 0.5 · (2) · (4)

A = 36 - 16

A = 20 units

Case C

A = 6² - 0.5 · 6² - 0.5 · 6 · 2

A = 36 - 18 - 6

A = 12 units

Case D

A = 6² - 2 · 0.5 · 6 · 4

A = 36 - 24

Answer:

b = (4/3), with rounding

Step-by-step explanation:

Area = A, in cm^2

n = days

A(n) = \(A_{0}\)\(b^{n}\)

------------------

Data:

n = 2, A = 1.8

A(n) = \(A_{0}\)\(b^{n}\)

1.8 =  \(A_{0}\)\(b^{2}\)

n = 3, A = 2.4

2.4 = \(A_{0}\)\(b^{3}\)

Although we are not given the initial area, we can still make the calculation since we have two data points and each has the same initial area, \(A_{0}\).  Lets take the first equation and multiply it by b, in order to bring the \(b^{2}\) to \(b^{3}\)

1.8 =  \(A_{0}\)\(b^{2}\)

b(1.8 =  \(A_{0}\)\(b^{2}\))

1.8b = \(A_{0}\)\(b^{3}\)

We can know from the second equation that 2.4 = \(A_{0}\)\(b^{3}\) .  We can eliminate this term in the above relationship by substituting 2.4:

1.8b = \(A_{0}\)\(b^{3}\)

1.8b = 2.4

b =  1.3333

       or (4/3)

Check:

Does the value of (4/3) for b work for both data points?  To check this, we do need to assume an initial starting area.  Lets assume the starting area, \(A_{0}\) = 1.

n = 2, A = 1.8, b = (4/3)

A(n) = \(A_{0}\)\(b^{n}\)

1.8 =  1*\((4/3)^{n}\)

1.8 =  1.78  Close enough?

n = 3, A = 2.4, b = (4/3)

2.4 = \(A_{0}\)\((4/3)^{n}\)

2.4 = 1*\((4/3)^{3}\)

2.4 = 2.37 Close enough?

Answer:

C.) |t−0.5|=98.6

Step-by-step explanation:

Since a person's normal body temperature should remain within 0.5 degrees Fahrenheit of 98.6ºF. The equation which can be used to determine the lowest and the highest body temperature that would be considered normal is;

|t−0.5|=98.6

Conversion of Degree Celsius to Fahrenheit.

0°C = 32°F

0.5°C = 32.9°F

Let's assume we have a temperature of 100°F, 20°F, 200°F

Substituting these values into the equation, we have;

|100−32.9|=67.1°F

|20−32.9|= -12.9°F

|200−32.9|=167.1°F

This temperature (67.1°F) is within the normal range.

This temperature (-12.9°F) is below the normal range.

This temperature (167.1°F) is above the normal range.

Based on the information in the graph and the figures, we can infer that a true statement about these figures is: There is at least one similarity transformation that will map ABCD to EFGH.

According to the information in the graph, we can show that the figures ABCD and DEFG are similar in shape. In fact, we could say that ABCD is a smaller scale than DEFG, because their sides and angles are similar.

However, this figure has some transformations, in particular the most notorious transformation is the rotation that has been given to it in the form of a mirror due to the fact that its longest side is to the left and not to the right like the DEFG figure.

The measure of angle A, B, C are 60°,60°,60°

A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices. A triangle is also a polygon.

The sum of angle in a polygon is 180°. i.e

A+B + C = 180°

therefore we can say that;

2x+2x + 3x-30 = 180

7x -30 = 180

7x = 180+30

7x = 210

divide both sides by 7

x = 210/7 = 30

If you look at the attached graph, it is simply a matter of checking each graph for the corresponding x-value, \(\frac{\pi}{2}\).

To test the hypothesis that the mean weight of two sheets is equal (μ1 - μ2) against the alternative that it is not, and assuming equal variances, we can use a two-sample t-test. The t-statistic can be calculated using the following formula:

t = (x1 - x2) / (s_p * sqrt(1/n1 + 1/n2))

where:

x1 and x2 are the sample means of the two sheets,

s_p is the pooled standard deviation,

n1 and n2 are the sample sizes.

The pooled standard deviation (s_p) can be calculated using the following formula:

s_p = sqrt(((n1 - 1) * s1^2 + (n2 - 1) * s2^2) / (n1 + n2 - 2))

where:

s1 and s2 are the sample standard deviations.

To calculate the t-statistic, we need the sample means, sample standard deviations, and sample sizes.

The correct answer is option A. The sample standard deviation can be used as an estimate of the population standard deviation is the statement that explains the use of the sample standard deviation in tests of the mean when the population standard deviation is not known.

By taking the square root of the variance, the sample standard deviation—a measurement of the data's propagation derived. A sample, which is a smaller portion of the population, is used to calculate it.

The sample standard deviation can be used as an estimate of the population standard deviation because the population standard deviation is typically unknown.

Following that, confidence intervals and other tests of the mean can be computed using this.

The sample standard deviation is another tool used to assess the data's variability because it shows how dispersed the data exists.

The lengths of the two pieces of a wire will be 19,19.

A square is a closed, two-dimensional object with four equal sides and four vertices. On either side, it has parallel sides.

The square of a square's side determines its area.

Given data -

Length of a wire = 38 m

As the wire is divided into two pieces,

Let the length of two pieces of wire be x and y m respectively.

As per given data, x + y = 38

Therefore, y = 38 - x    

As each piece is bent into a square, area of squares will be

\((x/4)^{2}\)  and  \((y/4)^{2}\)

Therefore, the sum of areas of two squares will be A = \((x/4)^{2}\) +      \((y/4)^{2}\)

A = \(x^{2}\)/16 + \(y^{2}\)/16

A = \(x^{2}\)/16 + \((38-x)^{2}\)/16

By differentiating, we will get

A' = \(\frac{2x}{16}\) - \(\frac{2(38-x)}{16}\)

In order to minimize the the sum of the areas of the two squares, we will take A' = 0

0 = x - (38 - x)

2x = 38

x = 19

Therefore y = 19

The length of two pieces of a wire should be 19 m each.

Answer:

h≈2.86

Step-by-step explanation:

According to the given information for the normal distribution, we can expect that the corresponding z-score may be negative.

It is given to us that -

The normal distribution has mean 11

The normal distribution has data value of 9

We have to find out if the corresponding z-score is to be positive or negative.

The z-score calculates the number of standard deviations higher or lower the mean, the data point is present.

The formula for z-score is given by -

\(z=\frac{data point - mean}{standard deviation}\)

Although we do not have the value of standard deviation in the question, we can see that the value of

data point - mean = 9-11 = -2

So, we can see that the numerator of the z-value formula is already negative.

Thus, we can expect that the corresponding z-score may be negative according to the information provided for the normal distribution.
