Determine The Relationship Between The Two Triangles And Whether Ornot They Can Be Proven To Be Congruent.The

Answers

Answer 1

The two triangles are related by SAS criteria, so the triangles are congruent.

What are congruent triangles?

Congruent triangles are triangles that are precisely the same size and form. When the three sides and three angles of one triangle match the same dimensions as the three sides and three angles of another triangle, two triangles are said to be congruent. Corresponding portions are those areas of the two triangles that share the same dimensions (are congruent). This indicates that corresponding triangle parts are congruent (CPCTC).

From the given figure we observe for that the two triangles two sides and the corresponding angle of 90 degree is similar.

Thus, using the SAS criteria we see that the two triangles are equal.

Hence, the two triangles are related by SAS criteria, so the triangles are congruent.

Step-by-step explanation:

If n is an integer and n > 1, then n! is the product of n and every other positive integer that is less than n. for example, 5! = 5 x 4 x 3 x 2 x 1a. Write 6! in standard factored formb. Write 20! in standard factored formc. Without computing the value of (20!)2, determine how many zeros are at the end of this number when it is written in decimal form. Justify your answer

Answers

a. 6! = 6 x 5 x 4 x 3 x 2 x 1 = 720. b. 20! = 20 x 19 x 18 x ... x 2 x 1. c. There are 16 zeros at the end of the decimal representation of (20!)2.

a. 6! = 6 x 5 x 4 x 3 x 2 x 1 = 720

b. 20! = 20 x 19 x 18 x ... x 2 x 1. To write this in factored form, we can identify the prime factors of each number and write the product using exponents. For example, 20 = 2² x 5, so we can write 20! as:

20! = (2² x 5) x 19 x (2 x 3²) x 17 x (2² x 7) x 13 x (2 x 2 x 3) x 11 x (2³) x (3) x (2) x 7 x (2) x 5 x (2) x 3 x 2 x 1

Simplifying, we get:

20! = 2¹⁸ x 3⁸ x 5⁴ x 7² x 11 x 13 x 17 x 19

c. The number of zeros at the end of (20!)² in decimal form is determined by the number of factors of 10, which is equivalent to the number of factors of 2 x 5. Since there are more factors of 2 than 5 in the prime factorization of (20!)², we only need to count the number of factors of 5. There are four factors of 5 in the prime factorization of 20!, which contribute four factors of 10 to the square. Therefore, (20!)²ends in 8 zeros when written in decimal form.

Select which function f has an inverse g that satisfies g prime of 2 equals 1 over 6 period
f(x) = 2x3
f of x equals 1 over 8 times x cubed
f(x) = x3

Answers

The function that satisfies  F Has An Inverse G That Satisfies G'(2) = 1/6 is f(x) = 2x³ (option a).

More precisely, if f(x) is a function, then its inverse function g(x) satisfies the following two conditions:

g(f(x)) = x for all x in the domain of f

f(g(x)) = x for all x in the domain of g

In other words, if we apply f(x) to an input value x, and then apply g(x) to the resulting output, we get back to the original input value.

Now, let's look at the given condition: G'(2) = 1/6. This means that the derivative of the inverse function at x=2 is 1/6. We can use this condition to eliminate some of the options.

f(x) = 2x³

If we take the derivative of f(x), we get: f'(x) = 6x²

To find the inverse function, we can solve for x in the equation y = 2x³:

x = [tex]y/2^{(1/3)}[/tex]

Now we can express the inverse function g(x) in terms of y:

g(y) = [tex]y/2^{(1/3)}[/tex]

To find the derivative of g(x), we use the chain rule:

g'(x) = f'(g(x))⁻¹

g'(2) = f'(g(2))⁻¹

g'(2) = f'([tex]1/2^{(1/3)}[/tex])⁻¹

g'(2) = 6([tex]1/2^{(1/3)}[/tex])²)⁻¹

g'(2) = 6/36 = 1/6

Since g'(2) = 1/6, option a) is the correct answer.

Find the value of the derivative (if it exists) at the given extremum. (If an answer does not exist, enter DNE.) f(x) = (x + 4)^2/3 f'(-4) = Find the critical numbers of the function. f(x) = x^6 - 6x^5

Answers

The critical numbers of f(x)  = x^6 - 6x^5 are x = 0 and x = 5 at the given extremum.

To find the derivative of f(x), we use the chain rule and power rule:

f(x) = (x + 4)^(2/3)

f'(x) = (2/3)(x + 4)^(-1/3)(1)

f'(-4) = (2/3)(-4 + 4)^(-1/3)(1) = DNE (the derivative does not exist at x = -4)

To find the critical numbers of f(x), we first find the derivative:

f(x) = x^6 - 6x^5

f'(x) = 6x^5 - 30x^4

Next, we set the derivative equal to zero and solve for x:

6x^5 - 30x^4 = 0

6x^4(x - 5) = 0

So the critical numbers of f(x) are x = 0 and x = 5.

In general terms, a distribution refers to the way something is divided or spread out. In the context of statistics and probability theory, a distribution is a mathematical function that describes the likelihood of different possible outcomes or values that a variable can take.

There are various types of distributions, but some of the most commonly used ones include:

Normal distribution: also known as the Gaussian distribution, it is a continuous probability distribution that is symmetrical around the mean, with most of the data falling within one standard deviation of the mean.

Binomial distribution: this is a discrete probability distribution that describes the likelihood of a certain number of successes in a fixed number of trials.

Poisson distribution: another discrete probability distribution that describes the likelihood of a certain number of events occurring in a fixed interval of time or space.

Exponential distribution: a continuous probability distribution that describes the time between events occurring at a constant rate.

Distributions are essential in statistical analysis as they can help to understand and analyze data, make predictions, and draw conclusions about a population based on a sample of data.

An angle is a form in Euclidean geometry that is composed of a pair of rays, known as such angle's sides, that meet at a center point known as the angle's vertex. Two rays may merge to generate an angle in the plane in which they are located. An angle is formed when two planes collide. They are known as dihedral angles. In plane geometry, an angle is a potential arrangement of two rays or lines whose share a termination. The English term "angle" is derived from the Latin word "angulus," which means "horn." The apex is the point in which the two rays, often known as the angle's sides, converge.

Consider parallelogram ABCD below.
Use the information given in the figure to find m/BAC, m/B, and x.

Answers

Answer:

Since opposite angles in a parallelogram are congruent, we know that:

m∠DAB = m∠BCD = 67°

Since ∠BAC and ∠BCD are adjacent angles, we know that:

m∠BAC + m∠BCD = 180°

So we can solve for m∠BAC:

m∠BAC + 67° = 180°

m∠BAC = 113°

Since opposite angles in a parallelogram are congruent, we know that:

m∠BAD = m∠BC

So we can solve for m∠BC:

m∠BAD = 16

m∠BC = 16°

Finally, we can solve for x by using the fact that the interior angles of a quadrilateral sum to 360 degrees:

m∠DAB + m∠BAC + m∠BCD + m∠CDA = 360°

67° + 113° + m∠BCD + 90° = 360°

m∠BCD = 90°

So we can solve for x:

m∠4B - m∠BCD = 90° - 90° = 0

4x - 59° = 0

4x = 59°

x = 14.75°

Therefore, m/BAC = 113°, m/B = 16°, and x = 14.75°.

Answers

The volume of the solid is given by the equation V = 36π (√2 - 1) using the triple integral.

A three-dimensional object's volume in three-dimensional space may be determined using the triple integral. The three-variable function is represented by the triple integral. If in space is a closed region, the region's entire volume may be expressed as V = Ddv, which is equivalent to V = D d x d y d z.

Cone: z = [tex]\sqrt{x^2+y^2}[/tex]

sphere: x² + y² + z² = 18

Here, we will use cylindrical coordinates to evaluate volume:

x = rcosθ , y = rsinθ, z = z

so, z = [tex]\sqrt{r^2cos^2\theta+r^2sin^2\theta} =r[/tex]

z = [tex]\sqrt{18-(x^2+y^2)} =\sqrt{18-r^2}[/tex]

r = [tex]\sqrt{18-r^2}[/tex]

r = 3

Finding limits,

[tex]Volume = \int\limits^2_0 \int\limits^3_0\int\limits^a_r {rdzdrd\theta} \, \\\\= \int\limits^2_0 \int\limits^3_0rz \ drd\theta\\\\= \int\limits^2_0 \int\limits^3_0 r(\sqrt{18-r^2}-r ) \ drd\theta\\\\[/tex]

Volume = 2π [(18√2-9) - 9]

The particular solution of Differential equation y" – 2y' + 2y = et sin x is yp = (1/2et - 1/2et cos(x))sin(x).

We assume the particular solution is of the form of given differential equation is

yp = (Aet + Bcos(t))sin(x) + (Cet + Dsin(t))cos(x)

where A, B, C, and D are constants to be determined.

Taking the first and second derivative of yp with respect to t:

yp' = Aet sin(x) - Bsin(t)sin(x) + Cet cos(x) + Dcos(t)cos(x)

yp'' = Aet sin(x) - Bcos(t)sin(x) - Cet sin(x) + Dsin(x)cos(t)

Substituting these into the differential equation and simplifying, we get:

(et sin x) = (A - C)et sin(x) + (B - D)cos(x)sin(t)

Since et sin x is not a solution to the homogeneous equation, the coefficients of et sin x and cos(x)sin(t) on both sides of the equation must be equal. Therefore:

A - C = 1 and B - D = 0

Solving for A, B, C, and D, we get:

A = 1/2, B = 0, C = -1/2, D = 0

Answers

Yes. they can in fact, more than two independent variables can have the same distribution. Two random vectors follow the same distribution, which means that each marginalized variable must follow the same distribution.

In probability theory and statistics, the marginal distribution of a subset of a set of random variables is the probability distribution of the variables contained in that subset. It gives the probability of different values ​​of variables in the subset without reference to the values ​​of other variables. This contrasts with conditional distributions, which give probabilities based on the values ​​of other variables.

The marginal variables are the variables of the subset of variables which are retained. These concepts are "marginal" because they can be found by adding the values ​​of the rows or columns of a table and writing the sum in the blank space of the table.

The distribution of the marginal variable (marginal distribution) is obtained by marginalizing the distribution of the suppressed variable (that is, focusing on the sum in the margin), and the suppressed variable is called marginalized.

Answers

If 2 books are chosen at random, then the probability that both are statistics books is (a) 1/21.

The number of statistics book in bookcase is = 2;

The number of biology books in bookcase is = 5;

So, the total number of books is = 7;

The Probability of choosing a statistics book on the first draw is 2/7, since there are 2 statistics books out of a total of 7 books.

After the first book is chosen, there will be 6 books left, including 1 statistics book out of a total of 6 books.

So, the probability of choosing another statistics book on the second draw is 1/6.

In order to find the probability of both events happening together (i.e. choosing 2 statistics books in a row), we multiply the probabilities of each event:

So, P(choosing 2 statistics books) = P(1st book is statistics) × P(2nd book is statistics given that the 1st book was statistics);

The bells bought a $386,000 house. They made a down payment of $49,000 and took out a mortgage for the rest. Over the course of 15 years they made monthly payments of $2843.81 on their mortgage until it was paid off.

What was the total amount they ended up paying for the house (including the down payment and monthly payments)?

How much interest did they pay on the mortgage?

Answers

Answer:

Step-by-step explanation:

The total amount paid for the house is the sum of the down payment and the total amount paid for the mortgage.

The total amount paid for the mortgage can be calculated as follows:

Number of monthly payments = 15 years x 12 months/year = 180 months

Total amount paid for the mortgage = 180 x $2843.81 = $511,086.80

Therefore, the total amount paid for the house is:

$386,000 + $511,086.80 = $897,086.80

To calculate the amount of interest paid, we need to subtract the principal amount (the original amount borrowed) from the total amount paid for the mortgage.

Principal amount = Total amount borrowed - Down payment = $386,000 - $49,000 = $337,000

Total interest paid = Total amount paid for the mortgage - Principal amount = $511,086.80 - $337,000 = $174,086.80

Therefore, they paid a total of $897,086.80 for the house, and they paid $174,086.80 in interest on their mortgage.

An instructor is administering a final examination. She tells her class that she with give an A grade to the 10% of the students who earns the highest marks. Past experience with the same examination has yielded grades that are normally distributed with a mean of 70 and a standard deviation of 10. If present class runs true to form, what numerical score would a student need to earn an A grade?

Answers

To earn an A grade, a student needs to score at least 82.8 , calculated using the inverse normal cumulative distribution function with a mean of 70, a standard deviation of 10, and a 10th percentile of 0.10.

Given that the grades are normally distributed with a mean of 70 and a standard deviation of 10.

We need to find the score which is at the 10th percentile of the distribution.

Using the standard normal distribution table, we can find the z-score that corresponds to the 10th percentile.

From the table, we can see that the z-score is approximately -1.28.

Using the formula for standardizing a normal distribution:

z = (x - μ) / σ

where z is the z-score, x is the raw score, μ is the mean, and σ is the standard deviation.

Substituting the given values, we have:

-1.28 = (x - 70) / 10

Solving for x, we get:

x = (-1.28 * 10) + 70

x = 82.8

Therefore, a student would need to earn a score of approximately 82.8 to receive an A grade.

What is the ships horizontal distance from the lighthouse(and the shore)? Round your answer to the nearest hundredth of a foot if necessary.

Answers

We can use trigonometry to solve this problem. Let's call the horizontal distance from the boat to the lighthouse "x". We can use the tangent function to find x:

tangent(8 degrees) = opposite / adjacent

tangent(8 degrees) = 148 / x

To solve for x, we can rearrange the equation:

x = 148 / tangent(8 degrees)

x ≈ 1041.87 feet

So the ship's horizontal distance from the lighthouse (and the shore) is approximately 1041.87 feet or 1041.87 rounded to the nearest hundredth of a foot if necessary.

Your answer is 1053.07

what is the integral of e^{\cos\left(e^{\cos\left(e^{\cos\left(e^{\cos\left(x\right)}\right)}\right)}\right)}

Answers

The integral of [sin x / cos x] + [cos x / sin x] is (1/2) x ln |tan x| - (1/2) x ln |sec x| + C

The integral you have provided can be rewritten as:

∫ [sin x / cos x] + [cos x / sin x] dx

Using algebraic manipulation, we can simplify this expression to:

∫ (sin² x + cos² x) / (cos x x sin x) dx

Now, we can use the method of partial fractions to break down the integrand into simpler fractions. To do this, we first need to factor the denominator:

cos x x sin x = (1/2) x (sin 2x)

We can then express the integrand as:

(sin² x + cos² x) / [(1/2) x (sin 2x)]

Using the partial fractions technique, we can express the integrand as:

(sin² x + cos² x) / [(1/2) x (sin 2x)] = A / sin 2x + B / cos 2x

where A and B are constants that we need to determine. To solve for A and B, we can multiply both sides by sin 2x x cos 2x, which gives us:

sin² x + cos² x = A x cos 2x + B x sin 2x

We can then use the trigonometric identities sin² x + cos² x = 1 and cos 2x = 2 x cos² x - 1, and sin 2x = 2 x sin x x cos x, to simplify the equation to:

1 = (2A - B) x cos² x + (2B) x sin x x cos x - A

We now have two equations (for x = 0 and x = π/2) and two unknowns (A and B), which we can solve simultaneously to obtain:

A = 1/2 and B = -1/2

Using these values, we can express the integrand as:

(sin² x + cos² x) / [(1/2) x (sin 2x)] = (1/2) x [1 / sin 2x - 1 / cos 2x]

We can now integrate each term separately:

∫ [sin x / cos x] + [cos x / sin x] dx = ∫ [(1/2) x (1 / sin 2x - 1 / cos 2x)] dx = (1/2) x ln |tan x| - (1/2) x ln |sec x| + C

where C is the constant of integration. Therefore, the final answer to the given integral is:

∫ [sin x / cos x] + [cos x / sin x] dx = (1/2) x ln |tan x| - (1/2) x ln |sec x| + C

4x + 3y = -6

Answers

The equation of the line that is parallel to the given line and passes through the point (-3, 2) is 3x - 4y = -17.

What is the formula for a parallel line equation?

If the line's equation is axe + by + c = 0 and the coordinates are (x1, y1).

To find the equation of a line parallel to a given line, we must first understand that parallel lines have the same slope. As a result, we must first determine the slope of the given line.

3x - 4y = -17 is the given line. To determine its slope, solve for y and write the equation in slope-intercept form:

-3x - 4y = -3x - 17 y = (3/4)x + (17/4)

This line has a 3/4 slope.

Now we want to find the equation of a parallel line that passes through the point (-3, 2). Because the new line is parallel to the given line, it has a slope of 3/4.

We can write the equation of the new line using the point-slope form of the equation of a line as:

y - y1 = m(x - x1)

where m represents the slope and (x1, y1) represents the given point (-3, 2).

When m = 3/4, x1 = -3, and y1 = 2, we get:

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

y - 2 = (3/4)(x + 3)

Divide both sides by 4 to get rid of the fraction.

4y - 8 = 3x + 9

3x - 4y = -17

As a result, the equation of the parallel line that passes through the point (-3, 2) is 3x - 4y = -17.

Find the coordinates of the center and the measure of the radius for a circle whose equation is(x - 8) + (y + 4) = 12

Answers

The center coordinates and radius of the given circle (x - 8)^2 + (y + 4)^2 = 12 is given by ( 8 ,-4 ) and 2√3 respectively.

Equation of the circle is equal to ,

(x - 8)^2 + (y + 4)^2 = 12.

Standard form of the equation of the circle is equals to,

( x - a )^2 + ( y - b )^2 = r^2  ___(1)

Where ( a, b ) are the coordinates of the center of the circle.

And r is the radius of the circle.

Convert the equation of the circle (x - 8)^2 + (y + 4)^2 = 12 into standard form we have,

(x - 8)^2 + (y + 4)^2 = ( 2√3 )^2  ___(2)

Compare equation (1) and (2) to get coordinates of the center and radius of the circle.

Here value of a = 8

value of b = -4

Radius of the circle 'r' = 2√3

Therefore, the center of the coordinates and radius of the circle is equal to ( 8 ,-4 ) and 2√3 respectively.

Answers

Sacramento, California's electricity demand on a scorching summer day is depicted in a function graph. The domain is 24 hours of a day.

The site is available around-the-clock.

One thousand two hundred megawatts are consumed at eight in the morning.

The hours between 4:00 and 6:00 pm saw the highest electricity use, while 4:00 am saw the lowest use.

It would be 1,900 megawatts for f (12).

From 4 am to 5 pm, usage rises, and from 5 pm to 4 am, it falls.

What is displayed by the graph?

Because each point on the graph reflects a different megawatt usage, the graph is a function. As this graph of electricity usage illustrates, the domain would be available throughout the entire day.

At 8 a.m., these megawatts are used:

= 1, 300 - ( 200 / 2 )

equal to 1,200 megawatts

As people get ready for work and leave for work, we can observe an increase in power demand from 4 am to 5 pm, but a reduction from 5 pm to 4 am.
