Answers

Answer 1

Answer:

d.32

Step-by-step explanation:

To get the Least Common Multiple (LCM) of 8 and 32 we need to factor each value first and then we choose all the factors which appear in any column and multiply them:

8:   222    

32:   22222

LCM:   22222

The Least Common Multiple (LCM) is:   2 x 2 x 2 x 2 x 2 = 32

Answer 2

The least common multiple is = 32

The denominators are 8 and 32.

The multiples of 8 are = 8, 16, 24, 32, 40, ....

The multiples of 32 are = 32, 64, ....

There's a 90° triangle. The other two angles are 30° and 60°. The shortest line is nine the longest line is C. It's asking what sea is in simplest radical form

Answers

Answer:

C = 18

Step-by-step explanation:

There's a 90° triangle. The other two angles are 30° and 60°. The shortest line is nine the longest line is C. It's asking what is C is in simplest radical form

Solution:

A triangle is a shape with three sides and three angles. Types of triangle are right angled, isosceles, scalene, obtuse, acute.

The length of the side in a triangle is directly proportional to the opposite angle (angle facing the side).

A right angled triangle is a triangle with one angle equals to 90 degrees.

Since the shortest line is 9, the angle facing the shortest line is the smallest angle. The longest line is the hypotenuse which is given as C. Trigonometric identities shows the relationship between the sides of a triangle and its angles, hence:

sin30 = 9 / C

0.5 = 9 / C

C = 9/0.5

C = 18

a histogram of sample means converges to a normal distribution as the sample size increases.. T/F

Answers

Yes, this is true. This phenomenon is known as the Central Limit Theorem and it states that, as the sample size increases, the distribution of the sample mean converges to a normal distribution.

Yes, this is true. According to the Central Limit Theorem, as the sample size increases, the distribution of the sample mean converges to a normal distribution. This means that, when the sample size is large enough, the histogram of sample means will appear to be close to a normal distribution. This is because the mean of a large enough sample size will be close to the population mean, regardless of the shape of the original population distribution.

The Central Limit Theorem also states that the larger the sample size, the more closely the sample distribution will resemble a normal distribution. This is why, when the sample size is large enough, a histogram of sample means will appear to be a normal distribution.

Use a double integral to find the area of the region.
The region inside the circle
(x − 4)² + y² = 16
and outside the circle
x² + y² = 16

Answers

To find the area of the region inside the circle (x - 4)² + y² = 16 and outside the circle x² + y² = 16, we can use a double integral. The area can be obtained by calculating the integral over the region defined by the two circles.

First, let's visualize the two circles. The circle (x - 4)² + y² = 16 has its center at (4, 0) and a radius of 4. The circle x² + y² = 16 has its center at the origin (0, 0) and also has a radius of 4.
To find the area between these two circles, we can set up a double integral over the region. Since the two circles are symmetric about the x-axis, we can integrate over the positive y-values and multiply the result by 2 to account for the entire region.
The integral can be set up as follows:
Area = 2 ∫[a, b] ∫[h(y), g(y)] dxdy
Here, [a, b] represents the interval of y-values where the circles intersect, and h(y) and g(y) represent the corresponding x-values for each y.
Solving the equations for the two circles, we find that the intervals for y are [-4, 0] and [0, 4]. For each interval, the corresponding x-values are given by x = -√(16 - y²) and x = √(16 - y²), respectively.
Now, we can evaluate the double integral:
Area = 2 ∫[-4, 0] ∫[-√(16 - y²), √(16 - y²)] dxdy
By integrating and simplifying the expression, we can find the area between the two circles.

show that if λ is an eigenvalue of a and x is an eigenvector belonging to λ. show that for m ≥ 1, λ m is an eigenvalue of am and x is an eigenvector of am belonging to λ m.

Answers

If λ is an eigenvalue of matrix A and x is the corresponding eigenvector, then for any positive integer m, λ^m is an eigenvalue of A^m, and x is the corresponding eigenvector of A^m.

Let λ be an eigenvalue of matrix A with eigenvector x. This means that Ax = λx. Now, consider the matrix A^m, where m is a positive integer. By multiplying both sides of the eigenvector equation by A^(m-1), we have A^(m-1)Ax = A^(m-1)(λx), which simplifies to A^mx = λA^(m-1)x.

Since A^mx = (A^m)x and A^(m-1)x = λ^(m-1)x, we can rewrite the equation as (A^m)x = λ^(m-1)(Ax). Using the initial eigenvector equation Ax = λx, we have (A^m)x = λ^(m-1)(λx), which further simplifies to (A^m)x = λ^m x.

Therefore, we have shown that if λ is an eigenvalue of A with eigenvector x, then for any positive integer m, λ^m is an eigenvalue of A^m with the same eigenvector x. This result demonstrates the relationship between eigenvalues and matrix powers, illustrating that raising the matrix to a power corresponds to raising the eigenvalue to the same power while keeping the eigenvector unchanged.

The absolute maximum and minimum values of f are 1 and -1, respectively.

The given function is f(x) = sin(x)

, where 0 <= x <= 2π.Sketch the graph of f by hand:graph of f(x) = sin(x)

(where 0 <= x <= 2π)

Use the graph of f to find the absolute and local maximum and minimum values of f.

The absolute maximum value of f is 1, which occurs at x = π/2.

The absolute minimum value of f is -1, which occurs at x = 3π/2.

The local maximum values of f are 1, which occur at x = π/2 + 2πk

(k = 0, ±1, ±2, ...), and the local minimum values of f are -1, which occur at

x = 3π/2 + 2πk

(k = 0, ±1, ±2, ...).

Thus, the absolute maximum value of f is 1, and it occurs at x = π/2, and the absolute minimum value of f is -1, and it occurs at x = 3π/2.

The local maximum values of f are 1, which occur at x = π/2 + 2πk

(k = 0, ±1, ±2, ...), and the local minimum values of f are -1, which occur a

t x = 3π/2 + 2πk (k = 0, ±1, ±2, ...).

We can now start by adding the ones place digits to find c0 = a0 + b0 = 9 + 9 = 18.

This gives a carry over of 1 to the next column.

To add the tens place digits, we add the two digits a1 and b1, and the carry-over of 1 from the previous column. Thus, c1 = a1 + b1 + 1 = 4 + 2 + 1 = 7.

Next, we add the hundreds place digits, we get c2 = a2 + b2 + 0 = 1 + 0 + 0 = 1. Since there is no carry-over, we leave the carry space blank.

Find the component form of the vector that translates A(-4,8) to A'(7,-9)

Answers

The component form of the vector that translates A to A' is (11, -17)

A translation is a type of transformation that takes each point in a figure and slides it the same distance in the same direction.

In translation, the shape of the figure does not change but its size may change.

Other transformation processes are reflection and rotation.

The component form of the vector is governed by the rule; A' - A

so we subtract corresponding x- coordinates and corresponding y- coordinates

A' - A = (7, -9) - (-4, 8)

Answers

(a) Annually compounded interest:

In this case, n = 1 (compounded once a year)

Future Value (a) = $500 × (1 + 0.12 / 1)^(1 * 20)

(b) Quarterly compounded interest:

In this case, n = 4 (compounded four times a year)

Future Value (b) = $500 × (1 + 0.12 / 4)^(4 * 20)

(c) Monthly compounded interest:

In this case, n = 12 (compounded twelve times a year)

Future Value (c) = $500 × (1 + 0.12 / 12)^(12 * 20)

Let's calculate the values:

(a) Future Value (annually) = $500 × (1 + 0.12)^20

Future Value (annually) ≈ $500 × 6.1917364224

Future Value (annually) ≈ $3,095.87

(b) Future Value (quarterly) = $500 × (1 + 0.12 / 4)^(4 * 20)

Future Value (quarterly) ≈ $500 × 1.03^80

Future Value (quarterly) ≈ $500 × 10.0626534032

Future Value (quarterly) ≈ $5,031.33

(c) Future Value (monthly) = $500 × (1 + 0.12 / 12)^(12 * 20)

315° = 7π/4 rad80° = 4π/9 rad225° = 5π/4 rad324° = 9π/5 rad

Step-by-step explanation:

Find the attachment in the diagram below,

In order to get the right match, we will use the conversion

180° = πrad

- For angle 315°;

If 180° = πrad

315° = a

Cross multiplying

180a = 315π rad

a = 315π rad/180

a = 63π/36 rad

a = 7π/4 rad

Hence 315° = 7π/4 rad

- For angle 80°;

If 180° = πrad

80° = b

Cross multiplying

180b = 80π rad

b = 80π rad/180

b = 8π/18 rad

b = 4π/9 rad

Hence, 80° = 4π/9 rad

- For angle 225°;

If 180° = πrad

225° = c  

Cross multiplying

180c = 225π rad

c = 225π rad/180

c = 15π/12 rad

c = 5π/4 rad

Hence, 225° = 5π/4 rad

- For angle 324°;

If 180° = πrad

324° = d

Cross multiplying

180d = 8324π rad

d = 324π rad/180

d = 27π/15 rad

d = 9π/5 rad

Hence, 324° = 9π/5 rad

Find the limit. Use l'Hospital's Rule where appropriate. If there is a more elementary method, consider using it. lim [In(x9 - 1) - In(x5- 1)]

Answers

The limit of the given expression as x approaches 1 from the right is 1.8.

To evaluate the limit of the given expression:

\(lim_{x - > 1} + [ln(x ^ 9 - 1) - ln(x ^ 5 - 1)]\)

We can start by directly substituting x = 1 into the expression:

[ln(1⁹ - 1) - ln(1⁵ - 1)]

= [ln(0) - ln(0)]

However, ln(0) is undefined, so this approach doesn't provide a meaningful answer.

To apply L'Hôpital's Rule, we need to rewrite the expression as a fraction and differentiate the numerator and denominator separately. Let's proceed with this approach:

\(lim_{x - > 1}\)+ [ln(x⁹ - 1) - ln(x⁵ - 1)]

= \(lim_{x - > 1}\)+ [ln((x⁹ - 1)/(x⁵ - 1))]

Now, we can differentiate the numerator and denominator with respect to x:

Numerator:

d/dx[(x⁹ - 1)] = 9x⁸

Denominator:

d/dx[(x⁵ - 1)] = 5x⁴

Taking the limit again:

\(lim_{x - > 1}\)+ [9x⁸ / 5x⁴]

= \(lim_{x - > 1}\)+ (9/5) * (x⁸ / x⁴)

= (9/5) * \(lim_{x - > 1}\)+ (x⁸ / x⁴)

Now, we can substitute x = 1 into the expression:

(9/5) * \(lim_{x - > 1}\)+ (1⁸ / 1⁴)

= (9/5) * \(lim_{x - > 1}\)+ 1

= (9/5) * 1

= 9/5

= 1.8

The complete question is:

Consider a sample with six observations of 16, 11, 13, 22, 15, and 19. Compute the z-score for each observation. (Leave no cells blank - be certain to enter "0" wherever required. Round your answers to 2 decimal places. Negative values should be indicated by a minus sign.) Sample observations z-score 16 11 13 22 15 19

Answers

To compute the z-score for each observation, we need to standardize the data using the formula z = (x - μ) / σ, where x is the individual observation, μ is the mean of the sample, and σ is the standard deviation of the sample.

Given the sample observations: 16, 11, 13, 22, 15, and 19, we can calculate the z-score for each observation as follows:

Calculate the mean (μ) of the sample:

μ = (16 + 11 + 13 + 22 + 15 + 19) / 6 = 16

Calculate the standard deviation (σ) of the sample:

Step 1: Calculate the squared deviations from the mean for each observation:

(16 - 16)², (11 - 16)², (13 - 16)², (22 - 16)², (15 - 16)², (19 - 16)²

0, 25, 9, 36, 1, 9

Step 2: Calculate the variance:

Variance = (0 + 25 + 9 + 36 + 1 + 9) / 6 = 80 / 6 ≈ 13.33

Step 3: Calculate the standard deviation:

σ = √(Variance) = √13.33 ≈ 3.65

Calculate the z-score for each observation:

z = (x - μ) / σ

For 16: z = (16 - 16) / 3.65 = 0 / 3.65 = 0

For 11: z = (11 - 16) / 3.65 = -5 / 3.65 ≈ -1.37

For 13: z = (13 - 16) / 3.65 = -3 / 3.65 ≈ -0.82

For 22: z = (22 - 16) / 3.65 = 6 / 3.65 ≈ 1.64

For 15: z = (15 - 16) / 3.65 = -1 / 3.65 ≈ -0.27

For 19: z = (19 - 16) / 3.65 = 3 / 3.65 ≈ 0.82

The z-scores for the given sample observations are: 0, -1.37, -0.82, 1.64, -0.27, and 0.82.

Integrate the function y = f(x) between x = 2.0 to x = 2.8, using the Trapezoidal rule with 8 strips. Assume a = 1.2, b = -0.587 y = a (1- e-bx)

Answers

Using the Trapezoidal rule and 8 strips, the integral of y = f(x) = a(1 - e(-bx)) from 2.0 to 2.8 is approximately equal to 1.926.

To integrate the function \(\[y = f(x) = a(1 - e^{-bx})\]\) using the Trapezoidal rule, we need to divide the interval [2.0, 2.8] into a number of strips (in this case, 8 strips) and approximate the integral using the trapezoidal formula.

The trapezoidal rule formula for approximating the integral is as follows:

\([\int_a^b f(x) , dx \approx \frac{h}{2} \left[ f(x_0) + 2f(x_1) + 2f(x_2) + \dots + 2f(x_{n-1}) + f(x_n) \right]]\)

where:

- h is the width of each strip \(\[h = \frac{b - a}{n}\]\), where n is the number of strips)

- x0 is the lower limit (2.0)

- xn is the upper limit (2.8)

- f(xi) represents the function evaluated at each strip's endpoint

Given the values a = 1.2 and b = -0.587, we can proceed with the calculations.

Step 1: Calculate the width of each strip (h):

\(\[h = \frac{b - a}{n} = \frac{-0.587 - 1.2}{8} = \frac{-1.787}{8} \approx -0.2234\]\)

Step 2: Calculate the function values at each strip's endpoint:

x₀ = 2.0

x₁ = x₀ + h = 2.0 + (-0.2234) = 1.7766

x₂ = x₁ + h = 1.7766 + (-0.2234) = 1.5532

x₃ = x₂ + h = 1.5532 + (-0.2234) = 1.3298

x₄ = x₃ + h = 1.3298 + (-0.2234) = 1.1064

x₅ = x₄ + h = 1.1064 + (-0.2234) = 0.883

x₆ = x₅ + h = 0.883 + (-0.2234) = 0.6596

x₇ = x₆ + h = 0.6596 + (-0.2234) = 0.4362

x₈ = x₇ + h = 0.4362 + (-0.2234) = 0.2128

xₙ = 2.8

Step 3: Evaluate the function at each strip's endpoint:

\([f(x_0) = 1.2 \left( 1 - e^{-(-0.587) \times 2.0} \right) = 1.2 \left( 1 - e^{1.174} \right) \approx \boxed{-2.082}][f(x_1) = 1.2 \left( 1 - e^{-(-0.587) \times 1.7766} \right) \approx -1.782][f(x_2) = 1.2 \left( 1 - e^{-(-0.587) \times 1.5532} \right) \approx -1.478][f(x_3) = 1.2 \left( 1 - e^{-(-0.587) \times 1.3298} \right) \approx -1.179][f(x_4) = 1.2 \left( 1 - e^{-(-0.587) \times 1.1064} \right) \approx -0.884]\)

\([f(x_5) = 1.2 \left( 1 - e^{-(-0.587) \times 0.883} \right) \approx -0.592]\)

0.592

\(\[f(x_6) = 1.2 \left( 1 - e^{-(-0.587) \times 0.6596} \right) \approx -0.303\]\[f(x_7) = 1.2 \left( 1 - e^{-(-0.587) \times 0.4362} \right) \approx -0.018\]\[f(x_8) = 1.2 \left( 1 - e^{-(-0.587) \times 0.2128} \right) \approx 0.267\]\[f(x_n) = 1.2 \left( 1 - e^{-(-0.587) \times 2.8} \right) \approx 0.647\]\)

Step 4: Apply the trapezoidal rule formula:

\([\int_{2.0}^{2.8} f(x) dx \approx \frac{h}{2} \left[ f(x_0) + 2f(x_1) + 2f(x_2) + \cdots + 2f(x_{n-1}) + f(x_n) \right]]\)

Simplifying the expression inside the brackets:

\([\frac{-0.2234}{2} \left[ -2.082 - 3.564 - 2.956 - 2.358 - 1.768 - 1.184 - 0.606 - 0.036 + 0.267 + 0.647 \right] = 1.6216606]\)

Calculating the values inside the brackets:

\(\[\frac{-0.2234}{2} \left[ -13.754 \right] = -3.4389\]\)

≈ 1.926

Therefore, the approximate value of the integral ∫[2.0, 2.8] f(x) dx using the Trapezoidal rule with 8 strips is approximately 1.926.

Shannon read that the latest model of a car made in Europe travels to speeds up to 120 kilometers per hour. Approximately how many per miles is 120 kilometers per hour? Show your work.

Answers

74.5645 miles is 120 kilometers per hour.

Both kilometers and miles represent units used to measure distance, and their magnitudes are comparable. The only distinction left is in the length units because both speed units have a time dimension that is measured in hours. A kilometer is a unit first from the metric system, whereas the mile is a part of something like the imperial unit system, which is used in many nations like the United States as well as the United Kingdom.Although it is a more recent measurement, the mile does have a lengthy history, going at least as far back as the Romans.The Roman mile was approximately 5,000 feet long, as well as additional miles with differing lengths in various locales and eras, such as the English, Irish, and Italian miles.

Divide the speed of the vehicle by 1.609 to get an approximation.

Therefore, 120 kilometers per hour = 120/1.609

=74.5645 miles per hour

74.5645 miles is 120 kilometers per hour.
