Using linear approximation, we can estimate the quantity [tex]126^(^1^/^2^)[/tex] by choosing a value of a close to 126 to minimize the error.

Linear approximation is a method that allows us to approximate the value of a function near a specific point by using the tangent line at that point. To estimate the quantity[tex]126^(^1^/^2^)[/tex], we choose a value of a close to 126, which will serve as the point for our linear approximation. Let's say we choose a = 121, which is close to 126.

Next, we find the equation of the tangent line to the function f(x) = [tex]x^(^1^/^2^)[/tex]at x = a. The equation of the tangent line can be expressed as y = f(a) + f'(a)(x - a), where f'(a) represents the derivative of f(x) at x = a.

In this case, f(x) = x^(1/2), and its derivative f'(x) = (1/2)[tex]x^(^-^1^/^2^)[/tex]. Evaluating f'(a) at a = 121, we find f'(121) = [tex](1/2)(121)^(^-^1^/^2^)[/tex]= 1/22.

Now, we substitute these values into the equation of the tangent line: y = f(121) + f'(121)(x - 121). Since f(121) = 11 and f'(121) = 1/22, the equation simplifies to y = 11 + (1/22)(x - 121).

To estimate 126^(1/2), we substitute x = 126 into the equation of the tangent line: y = 11 + (1/22)(126 - 121). Simplifying this expression, we find y ≈ 11.227.

Therefore, using linear approximation, we estimate that [tex]126^(^1^/^2^)[/tex] is approximately 11.227, with a small error due to the linear approximation.

In this scenario, a suitable probability distribution model to consider is the hypergeometric distribution.

The hypergeometric distribution is appropriate when sampling without replacement is involved and the population can be divided into two distinct categories. In this case, we have a population of 40 cars, 30 of which are compliant (success) and 10 that are not (failure).

1: Identify the relevant parameters.

Population size (N): 40 (total number of cars)

Number of successes in the population (K): 30 (number of compliant cars)

Sample size (n): 5 (number of cars chosen at random)

2: Define the probability distribution.

The formula gives the hypergeometric distribution:

P(X = k) = (K choose k) * ((N - K) choose (n - k)) / (N choose n)

3: Calculate the desired probabilities.

For example, you can calculate the probability of selecting exactly 2 compliant cars from the sample of 5 cars using the hypergeometric distribution formula.

In order for M to be considered an equivalence relation, it must satisfy three conditions: reflexivity, symmetry, and transitivity.

Reflexivity is when each element is related to itself, symmetry is when two elements are related to each other if they share the same relationship, and transitivity is when the relationship between two elements is transferred to a third element if it also shares the same relationship.

For M to be an equivalence relation:Reflexivity: Since the biological mother of a person is the same as the biological mother of that person, every person is related to itself under relation M. Symmetry: If person X has the same biological mother as person Y, then person Y also has the same biological mother as person X.

This implies that if X is related to Y under relation M, then Y is related to X under relation M.Transitivity: If person X has the same biological mother as person Y and person Y has the same biological mother as person Z, then person X and person Z have the same biological mother. This implies that if X is related to Y under relation M and Y is related to Z under relation M, then X is related to Z under relation M.Since M satisfies all three conditions for equivalence relation, we can say that M is an equivalence relation.

Answer:.

Step-by-step explanation:

A paired t-test can be defined as a statistical test that is utilized to compare the means of two related sets of samples. The data consists of nine pairs, and the initial value is subtracted from the second value.Δ0 = 0 is also given. As a result, the question is "Compute d."Here, first,The value of d is -0.27680007490074524.Answer: d = -0.27680007490074524.

we need to calculate the difference between the first and second values of each pair of data.

The differences of the given data are as follows: Pair Differences1 -1.95 2.2 -0.29 -9.02 4.17 -0.96 7.73 -4.47 -1.47

We need to compute d.

The formula to calculate d is as follows: d = (Mean of Differences - Δ0)/Standard Deviation of Differences Mean of Differences = Sum of Differences / Number of Differences= (-1.95 + 2.2 - 0.29 - 9.02 + 4.17 - 0.96 + 7.73 - 4.47 - 1.47) / 9 = -0.7377777777777779Δ0 = 0

Standard Deviation of Differences can be calculated by using the following formula

To find two real numbers that have a sum of 14 and a product of 38, we can set up a system of equations. Let's call the two numbers x and y.

From the problem statement, we have the following information:

Equation 1: x + y = 14 (sum of the two numbers is 14)

Equation 2: xy = 38 (product of the two numbers is 38)

To solve this system of equations, we can use substitution or elimination method. Let's solve it using substitution:

From Equation 1, we can express y in terms of x by subtracting x from both sides:

y = 14 - x

Now we substitute this value of y into Equation 2:

x(14 - x) = 38

Expanding the equation, we have:

14x - x^2 = 38

Rearranging the equation to bring it to quadratic form:

x^2 - 14x + 38 = 0

Now we can solve this quadratic equation. We can either factorize it or use the quadratic formula. However, upon examining the equation, we find that it doesn't factorize easily. Therefore, we'll use the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / 2a

For our quadratic equation, the coefficients are:

a = 1, b = -14, c = 38

Substituting these values into the quadratic formula, we have:

x = (-(-14) ± √((-14)^2 - 4(1)(38))) / (2(1))

x = (14 ± √(196 - 152)) / 2

x = (14 ± √44) / 2

x = (14 ± 2√11) / 2

Simplifying further, we have:

x = 7 ± √11

So we have two possible values for x: 7 + √11 and 7 - √11.

To find the corresponding values of y, we can substitute these values of x back into Equation 1:

For x = 7 + √11, y = 14 - (7 + √11) = 7 - √11

For x = 7 - √11, y = 14 - (7 - √11) = 7 + √11

Therefore, the two real numbers that have a sum of 14 and a product of 38 are (7 + √11) and (7 - √11).

The flux of F through the sphere is 16π.

To find the flux of the vector field, F= xy i + yz j + zxk out of a sphere of radius 2 centered at the origin, we shall apply the divergence theorem which states that the flux of a vector field through a closed surface is equal to the volume integral of the divergence of the vector field over the volume enclosed by the surface.

Thus, the problem can be solved as follows:

Integral of F over the sphere = flux of F through the sphere

= ∫∫ F . n dS,

where n is the outward normal unit vector to the sphere,

and dS is the surface area element of the sphere.

Since the sphere is centered at the origin, the vector field F has radial symmetry about the origin.

Therefore, we can write F = F(r) * r, where r is the radial unit vector.

Hence,[tex]F . n = F(r) * r . n = F(r) cos(θ)[/tex],

where θ is the angle between F and n.

For the sphere, θ = 0 everywhere, so cos(θ) = 1.

Thus, F . n = F(r).

Thus, the flux can be written as

[tex]∫∫ F . n dS = ∫∫ F(r) dS = ∫∫∫ div F(r) dV[/tex],

where div F(r) is the divergence of F evaluated at radial distance r.

We have, [tex]div F = ∂/∂x (xy) + ∂/∂y (yz) + ∂/∂z (zx)= y + z.[/tex]

Thus, div F(r) = 3r for r ≤ 2, and is zero elsewhere.

Therefore, we have,

∫∫ F . n dS = ∫∫∫ div F(r) dV

= ∫0π ∫0π ∫0²³ 3r r² sinθ dr dθ dφ

= 3 ∫0π ∫0π (sinθ) dθ dφ ∫0²³ r³ dr

= 3 * 2 * π * (1/3) * (2³)

= 16π

Thus, the flux of F through the sphere is 16π.

Outliers are data points that significantly deviate from the overall pattern of a dataset. They can be unusually high or low values compared to the rest of the data.

Outliers have different effects on the mean, median, and mode. Outliers have the most significant impact on the mean, as they can pull the average towards their extreme values. The median is less affected by outliers, as it only considers the middle value(s) in the dataset. Outliers have no direct impact on the mode, as it represents the most frequently occurring value(s) in the dataset.

Outliers can greatly influence the mean because the mean is sensitive to extreme values. When an outlier is significantly larger or smaller than the other data points, it can distort the average, pulling it towards the outlier's value. This is particularly true when the dataset is small or the outliers are prominent.

The median, on the other hand, is less affected by outliers. The median represents the middle value(s) in a dataset when the data points are sorted in ascending or descending order. Outliers that deviate from the overall pattern do not have a direct impact on the median, as long as they do not affect the position of the middle value(s).

The mode, which represents the most frequently occurring value(s) in the dataset, is not affected by outliers. Outliers do not directly influence the mode because it is determined solely by the frequency of values and not their magnitudes.

In summary, outliers can have a significant impact on the mean, pulling it toward its extreme values. However, outliers have little to no effect on the median and mode, as they represent the middle value(s) and most frequently occurring value(s) in the dataset, respectively.

The length l of an edge of each small cube if adjacent cubes touch but don't overlap is equal to the distance between the two parallel faces of the cube. It is also equivalent to the distance between the centers of opposite faces of the cube.

Let's assume that the length of each side of the cube is l and the distance between the centers of the opposite faces is L. The Pythagorean theorem can be used to determine L in terms of l. By drawing a line from the center of one face to the center of the opposite face through the center of the cube, you can form a right-angled triangle. L, l, and the diagonal of the face are the lengths of the sides of this triangle. Using the Pythagorean theorem, we getL^2 = l^2 + l^2L^2 = 2l^2L = l√2Therefore, the distance between the centers of the opposite faces of the cube is equal to l multiplied by the square root of 2.

Therefore, the length l of an edge of each small cube if adjacent cubes touch but don't overlap is equal to the distance between the two parallel faces of the cube, which is also equivalent to the distance between the centers of opposite faces of the cube. The length of the cube's edge is equivalent to the height of a cube with an edge of l that has two opposite vertices as the centers of the faces. The diagonal of the cube is equivalent to the hypotenuse of the right-angled triangle that is formed by the height and the side of the cube. It follows that the length of the diagonal of the cube is equal to the square root of 2 times the length of the side of the cube. Hence, the diagonal of a cube with sides of length l is l times the square root of 3.

There is no significant difference between the mean times that lean and mildly obese people spend lying down.

Therefore, the standard error (SE) = 38.9122 (rounded to four decimal places)

To determine whether there is a significant difference between the mean times the two groups spend lying down, we need to perform a two-sample t-test using the given data.

Using the four-step process, we will solve this problem.

Step 1: State the hypotheses.

H0: μ1 = μ2 (There is no significant difference in the mean times that lean and mildly obese people spend lying down)

Ha: μ1 ≠ μ2 (There is a significant difference in the mean times that lean and mildly obese people spend lying down)

Step 2: Set the level of significance.

α = 0.05

Step 3: Compute the test statistic.

Using the given data, we get the following information:

Mean of group 1 (lean) = 523.1236

Mean of group 2 (mildly obese) = 504.8571

Standard deviation of group 1 (lean) = 98.7361

Standard deviation of group 2 (mildly obese) = 73.3043

Sample size of group 1 (lean) = 10

Sample size of group 2 (mildly obese) = 10

To find the standard error, we can use the formula:

SE = √[(s12/n1) + (s22/n2)]

where s1 and s2 are the sample standard deviations,

n1 and n2 are the sample sizes, and

the square root (√) means to take the square root of the sum of the two variances.

Dividing the formula into parts, we have:

SE = √[(s12/n1)] + [(s22/n2)]

SE = √[(98.73612/10)] + [(73.30432/10)]

SE = √[9751.952/10] + [5374.364/10]

SE = √[975.1952] + [537.4364]

SE = √1512.6316SE = 38.9122

Rounded to four decimal places, the standard error is 38.9122.

To compute the test statistic, we can use the formula:

t = (x1 - x2) / SE

where x1 and x2 are the sample means and

SE is the standard error.

Substituting the values we have:

x1 = 523.1236x2 = 504.8571

SE = 38.9122t

= (523.1236 - 504.8571) / 38.9122t

= 0.4439

Rounded to four decimal places, the test statistic is 0.4439.

Step 4: Determine the p-value.

We can use statistical software of our choice to find the p-value.

Since the alternative hypothesis is two-tailed, we look for the area in both tails of the t-distribution that is beyond our test statistic.

t(9) = 2.262 (this is the value to be used to determine the p-value when α = 0.05 and degrees of freedom = 18)

Using statistical software, we find that the p-value is 0.6647.

Since 0.6647 > 0.05, we fail to reject the null hypothesis.

This means that there is no significant difference between the mean times that lean and mildly obese people spend lying down.

Therefore, the answer is: SE = 38.9122 (rounded to four decimal places)

(b) The appropriate value for C such that a randomly chosen bolt has a width less than C with probability 0.8508 is 967.28 mm.

(a) To find the probability that a randomly chosen bolt has a width between 944 and 957 mm, we need to calculate the area under the normal distribution curve between these two values.

We can standardize the values by subtracting the mean and dividing by the standard deviation, which gives us z-scores.

For the lower bound, (944 - 952) / 10 = -0.8, and for the upper bound, (957 - 952) / 10 = 0.5. Using a standard normal distribution table or a calculator, we can find the probabilities associated with these z-scores.

The probability for a z-score of -0.8 is 0.2119, and for a z-score of 0.5, it is 0.6915. To find the probability between these two values, we subtract the lower probability from the higher probability: 0.6915 - 0.2119 = 0.4796.

Rounding the answer to four decimal places, the probability that a randomly chosen bolt has a width between 944 and 957 mm is 0.3830.

(b) To find the appropriate value for C such that a randomly chosen bolt has a width less than C with probability 0.8508, we need to find the z-score associated with this probability.

Using a standard normal distribution table or a calculator, we find that the z-score for a cumulative probability of 0.8508 is approximately 1.0364.

We can then solve for C using the formula for z-score: z = (C - mean) / standard deviation. Rearranging the formula, we have C = (z * standard deviation) + mean. Plugging in the values, C = (1.0364 * 10) + 952 = 967.28 mm.

Rounding the answer to two decimal places, the appropriate value for C such that a randomly chosen bolt has a width less than C with probability 0.8508 is 967.28 mm.

The limit as x approaches infinity of g(x) is -2.

From the given slope field, we can observe that the differential equation dy/dx = y^2(4 - y^2) is associated with a family of curves. The solution to this differential equation is represented by the function y = g(x), with the initial condition g(-2) = -1.

To determine the behavior of g(x) as x approaches infinity, we need to analyze the long-term trend of the function. Notice that as y approaches 2 or -2, the slope of the tangent line becomes zero, indicating an equilibrium point. Therefore, the solution g(x) will approach the equilibrium points as x approaches infinity.

Since g(-2) = -1, we know that g(x) starts at -1 and moves towards one of the equilibrium points. Looking at the slope field, we can see that the solution curve approaches the equilibrium point at y = -2 as x increases. Hence, the limit as x approaches infinity of g(x) is -2.

In summary, based on the given slope field and the initial condition, the solution g(x) to the differential equation approaches -2 as x tends to infinity.

In this problem, we are asked to determine the largest degree of x that can be factored out of all the terms. To solve this, we need to look at the terms and identify the common factors of x. The options provided are 1, 2, 3, and 4.

If we look at the given terms, there is no variable x present in any of them. Therefore, we cannot factor out any powers of x from the terms. In other words, the degree of x in each term is 0. Hence, the largest degree of x that can be factored out of all the terms is 1, as x^1 is equivalent to x.

Factoring is a process in algebra where we break down an expression into its factors. It involves finding common factors and removing them from each term. By factoring, we can simplify expressions and solve equations more easily.

the answer is degree of the Maclaurin polynomial required for the error in the approximation of the function at the indicated value of x to be less than 0.001 is 7.

To determine the degree of the Maclaurin polynomial required for the error in the approximation of the function at the indicated value of x to be less than 0.001, given f(x) = sin(x), we need to approximate f(0.5).The formula to calculate the degree of Maclaurin polynomial required for the error in the approximation of the function at the indicated value of x to be less than the given amount is:$$R_n(x) = \frac{f^{n+1}(c)}{(n+1)!}(x-a)^{n+1}$$where c is a value between a and x, and Rn(x) is the remainder function.Then, to find the degree of the Maclaurin polynomial required for the error in the approximation of the function at the indicated value of x to be less than 0.001, we use the inequality:$$|R_n(x)| \leq \frac{M}{(n+1)!}|x-a|^{n+1}$$where M is an upper bound for the $(n+1)^{th}$ derivative of f on an interval containing a and x.To approximate f(0.5), we use the formula for the Maclaurin series expansion of sin(x):$$\sin(x) = \sum_{n=0}^{\infty}(-1)^n \frac{x^{2n+1}}{(2n+1)!}$$Thus, for f(x) = sin(x) and a = 0, we have:$$f(x) = \sin(x)$$$$f(0) = \sin(0) = 0$$$$f'(x) = \cos(x)$$$$f'(0) = \cos(0) = 1$$$$f''(x) = -\sin(x)$$$$f''(0) = -\sin(0) = 0$$$$f'''(x) = -\cos(x)$$$$f'''(0) = -\cos(0) = -1$$$$f^{(4)}(x) = \sin(x)$$$$f^{(4)}(0) = \sin(0) = 0$$$$f^{(5)}(x) = \cos(x)$$$$f^{(5)}(0) = \cos(0) = 1$$Thus, M = 1 for all values of x, and we have:$$|R_n(x)| \leq \frac{1}{(n+1)!}|x|^n$$To make this less than 0.001 when x = 0.5, we need to find n such that:$$\frac{1}{(n+1)!}0.5^{n+1} \leq 0.001$$Dividing both sides by 0.001 gives:$$\frac{1}{0.001(n+1)!}0.5^{n+1} \leq 1$$Taking the natural logarithm of both sides gives:$$\ln\left(\frac{0.5^{n+1}}{0.001(n+1)!}\right) \leq 0$$Using a calculator, we can find that the smallest value of n that satisfies this inequality is n = 7. Therefore, the degree of the Maclaurin polynomial required for the error in the approximation of sin(0.5) to be less than 0.001 is 7.

The degree of the Maclaurin polynomial required for the error in the approximation of the function at the indicated value of x to be less than 0.001 is 3.

Given the function f(x) = sin(x) and we need to determine the degree of the Maclaurin polynomial required for the error in the approximation of the function at the indicated value of x to be less than 0.001.

We need to approximate f(0.5).

Maclaurin Polynomial: The Maclaurin polynomial of order n for a given function f(x) is the nth-degree Taylor polynomial for f(x) at x = 0. It is given by the formula:

[tex]Pn(x) = f(0) + f'(0)x + f''(0)x²/2! + ... + fⁿ⁽ᶰ⁾(0)xⁿ/ⁿ![/tex]

Where fⁿ⁽ᶰ⁾(0) denotes the nth derivative of f(x) evaluated at x = 0.

To determine the degree of the Maclaurin polynomial required for the error in the approximation of the function at the indicated value of x to be less than 0.001, we use the error formula.

Error formula:

[tex]|f(x) - Pn(x)| <= M(x-a)^(n+1)/(n+1)![/tex]

where M = max|fⁿ⁽ᶰ⁾(x)| over the interval containing x and a. For f(x) = sin(x)

and a = 0, we have f(0) = sin(0) = 0, f'(x) = cos(x), f''(x) = -sin(x), f'''(x) = -cos(x), f⁽⁴⁾(x) = sin(x), f⁽⁵⁾(x) = cos(x), f⁽⁶⁾(x) = -sin(x), ...

Thus, [tex]|f⁽ⁿ⁾(x)| <= 1[/tex] for all n and x.

Therefore, [tex]M = 1.|x-a| = |0.5-0| = 0.5[/tex]

Thus,[tex]|f(x) - Pn(x)| <= M(x-a)^(n+1)/(n+1)![/tex]

=> [tex]|sin(x) - Pn(x)| <= 0.5^(n+1)/(n+1)![/tex]

We need [tex]|sin(0.5) - Pn(0.5)| <= 0.001[/tex].

So, [tex]0.5^(n+1)/(n+1)! <= 0.001[/tex]

n = 3 (Minimum value of n to satisfy the condition).

Using the Maclaurin polynomial of degree 3, we have

[tex]P₃(x) = sin(0) + cos(0)x - sin(0)x²/2! - cos(0)x³/3! = x - x³/3[/tex]

Therefore, the degree of the Maclaurin polynomial required for the error in the approximation of the function at the indicated value of x to be less than 0.001 is 3.

The domain restrictions of the expression h^2 + 3h - 10 / h^2 - 12h + 20 are all real numbers except for the values of h that make the denominator zero.

To find the domain restrictions of the given expression, we need to determine the values of h that would make the denominator zero, as dividing by zero is undefined.

The given expression has a denominator of h^2 - 12h + 20. To find the values of h that make the denominator zero, we set the denominator equal to zero and solve for h:

h^2 - 12h + 20 = 0

We can solve this quadratic equation by factoring or using the quadratic formula. However, since the focus here is on domain restrictions, we'll provide the factored form of the equation:

(h - 10)(h - 2) = 0

From this equation, we can see that the values of h that make the denominator zero are h = 10 and h = 2. Therefore, the domain restrictions of the expression are all real numbers except for h = 10 and h = 2.

In summary, the expression h^2 + 3h - 10 / h^2 - 12h + 20 is defined for all real numbers except h = 10 and h = 2.

We compare the test statistic to the critical value:

If |z| > 1.96, we reject the null hypothesis.

If |z| ≤ 1.96, we fail to reject the null hypothesis.

To determine if there is a significant difference in the proportion of mail carriers bitten by animals between Cleveland and Philadelphia, we can conduct a hypothesis test.

Let p1 be the proportion of mail carriers bitten by animals in Cleveland, and p2 be the proportion in Philadelphia.

The null hypothesis (H0) is that there is no difference in the proportions, which can be stated as:

H0: p1 = p2

The alternative hypothesis (Ha) is that there is a difference in the proportions, which can be stated as:

Ha: p1 ≠ p2

We can perform a two-sample proportion z-test to test this hypothesis. The formula for the test statistic is:

z = (p1 - p2) / √(p_pool * (1 - p_pool) * (1/n1 + 1/n2))

where p_pool is the pooled proportion, calculated as:

p_pool = (x1 + x2) / (n1 + n2)

In this case, x1 = 10 (number of mail carriers bitten in Cleveland), x2 = 16 (number of mail carriers bitten in Philadelphia), n1 = 73 (sample size in Cleveland), and n2 = 80 (sample size in Philadelphia).

First, let's calculate the pooled proportion:

p_pool = (10 + 16) / (73 + 80) = 26 / 153 ≈ 0.169

Next, let's calculate the test statistic:

z = (10/73 - 16/80) / √(0.169 * (1 - 0.169) * (1/73 + 1/80))

Using a standard normal distribution table or calculator, we can find the critical value for a two-tailed test at a significance level of 0.05. The critical value is approximately ±1.96.

Finally, we compare the test statistic to the critical value:

If |z| > 1.96, we reject the null hypothesis.

If |z| ≤ 1.96, we fail to reject the null hypothesis.

The correct option is A. Given that the mean height of a resident in a city is 68 inches and the standard deviation is 2.5 inches, and we are to find the probability that the average of 25 randomly selected residents will be about 68.2 inches.

The standard error of the mean can be calculated as follows:

Standard error of the mean = standard deviation / sqrt(sample size)

Standard error of the mean = 2.5 / sqrt(25)

Standard error of the mean = 0.5 inches

Now, the probability that the average of 25 residents will be about 68.2 inches can be calculated using the z-score formula as follows:

z = (x - μ) / SE

where, x = 68.2 (sample mean), μ = 68 (population mean), and SE = 0.5 (standard error of the mean)z = (68.2 - 68) / 0.5z = 0.4

To find the volume of the solid B, we need to integrate the areas of the cross sections perpendicular to the x-axis over the interval of x-values that define the base circle.

The equation of the base circle is x^2 + y^2 = 42. This is a circle with radius sqrt(42).

Each cross section perpendicular to the x-axis is an equilateral triangle. The height of each triangle is equal to the radius of the circle, which is sqrt(42), and the length of each side is also equal to the radius.

The area of an equilateral triangle is given by the formula A = (sqrt(3)/4) * s^2, where s is the length of a side. In this case, s = sqrt(42).

Now we can set up the integral to calculate the volume:

V = ∫[a, b] A(x) dx

where A(x) is the area of the cross section at a given x-value.

Since the base circle is symmetric about the y-axis, we can integrate from -sqrt(42) to sqrt(42) to cover the entire base circle.

V = ∫[-sqrt(42), sqrt(42)] (sqrt(3)/4) * (sqrt(42))^2 dx

Simplifying the expression:

V = (sqrt(3)/4) * 42 * ∫[-sqrt(42), sqrt(42)] dx

V = (sqrt(3)/4) * 42 * [x]∣[-sqrt(42), sqrt(42)]

V = (sqrt(3)/4) * 42 * (sqrt(42) - (-sqrt(42)))

V = (sqrt(3)/4) * 42 * 2sqrt(42)

V = (sqrt(3)/2) * 42 * sqrt(42)

V = (21sqrt(3)) * sqrt(42)

V = 21sqrt(126)

Finally, we can simplify the expression for the volume:

V = 21 * sqrt(9 * 14)

V = 63sqrt(14)

The area of the curved surface of the cone is approximately [tex]876.12 cm^2.[/tex]

To find the area of the curved surface of the cone, we need to calculate the circumference of the base and the slant height of the cone.

The radius of the sector is given as 14 cm, and the angle of the sector is 90°.  

Since the angle is 90°, it forms a quarter of a circle.

The circumference of the base of the cone is equal to the circumference of a circle with radius 14 cm, which can be calculated using the formula:

C = 2πr = 2π(14) = 28π cm.

Next, we need to find the slant height of the cone.

The slant height can be calculated using the Pythagorean theorem. We have a right triangle with the radius as the base (14 cm), the height as the radius of the sector (14 cm), and the slant height as the hypotenuse. Using the Pythagorean theorem, we can solve for the slant height (l):

l^2 = r^2 + h^2

l^2 = 14^2 + 14^2

l^2 = 196 + 196

l^2 = 392

l ≈ 19.8 cm.

Now we have the circumference of the base (28π cm) and the slant height (19.8 cm).

The curved surface area of the cone can be calculated using the formula:

Curved Surface Area = πrl ,
