How do you simplify a radical?

Answers

Answer 1

Answer:

\(\huge\boxed{\texttt{See Explanation}}\)

Step-by-step explanation:

In order to simplify a radical, we're looking for a perfect square within that number.

Say we have \(\sqrt{108}\).

We're looking for two numbers, where

1. We can easily find the square root of the first number

2. When we multiply that number by the second, we get 108.

We can experiment with numbers for 108. We know that \(36 \cdot 3 = 108\), so we can form this statement now.

\(\sqrt{108} = \sqrt{36 \cdot 3}\)

We know the square root of 36 is 6. Therefore, we can put this outside the square root sign and leave 3 inside.

\(\sqrt{36} = 6\\6\sqrt{3}\)

Hope this helped!

Find the surface area of the part of the surface z = 2/3(x^3/2 + y^3/2) that lies above the triangle enclosed by the lines x = 0, y = 0, and 2x+3y = 6.

Answers

To find the surface area of the part of the surface z = (2/3)(\(x^(3/2)\) + \(y^(3/2)\)) that lies above the triangle enclosed by the lines x = 0, y = 0, and 2x + 3y = 6, we need to perform a double integral over the region of the triangle.

Let's begin by finding the bounds for the double integral. The triangle is enclosed by the lines x = 0, y = 0, and 2x + 3y = 6.

To determine the bounds for x, we set y = 0 in the equation 2x + 3y = 6:

2x + 3(0) = 6

2x = 6

x = 3

So the bounds for x are 0 ≤ x ≤ 3.

To determine the bounds for y, we set x = 0 in the equation 2x + 3y = 6:

2(0) + 3y = 6

3y = 6

y = 2

So the bounds for y are 0 ≤ y ≤ 2.

Now, we can set up the double integral for the surface area:

Surface Area = ∬R √(1 + \((∂z/∂x)^2\) + \((∂z/∂y)^2\)) dA

where R represents the region of integration, and (∂z/∂x) and (∂z/∂y) are the partial derivatives of z with respect to x and y, respectively.

The surface area element dA is given by dA = dx dy.

First, let's find the partial derivatives of z:

∂z/∂x = (∂/∂x)(2/3)(\(x^(3/2) + y^(3/2)\))

        = (2/3)(3/2)\(x^(1/2)\)

        = \(x^(1/2)\)

∂z/∂y = (∂/∂y)(2/3)(\(x^(3/2) + y^(3/2)\))

        = (2/3)(3/2)\(y^(1/2)\)

        = \(y^(1/2)\)

Now, we can compute the surface area using the double integral:

Surface Area = ∬R √(1 + \((∂z/∂x)^2\) +\((∂z/∂y)^2\)) dx dy

            = ∫(0 to 3) ∫(0 to 2) √(1 + \((x^(1/2))^2\) + \((y^(1/2))^2\)) dx dy

Since the integration limits are constants, we can evaluate the integrals in any order. Let's start by integrating with respect to x:

Surface Area = ∫(0 to 2) ∫(0 to 3) √(1 + \((x^(1/2))^2\) + \((y^(1/2))^2\)) dy dx

Integrating with respect to y:

Surface Area = ∫(0 to 2) [ y * √(1 +\((x^(1/2))^2\) + \((y^(1/2))^2)\) ] (0 to 3) dx

Now we can proceed to evaluate the integral:

Surface Area = ∫(0 to 2) [ 3 * √(1 + \((x^(1/2))^2 + (y^(1/2))^2)\) ] dx

Unfortunately, this integral does not have a simple closed-form solution. We would need to evaluate it numerically or approximate it using numerical methods

Compute the double integral A = ₀∫³₁∫³ (x² + 3xy) dx dy

Answers

The answer of the question based on the Integral is , the value of the double integral is 51.75.

The double integral can be computed as follows;

Given that A = ₀∫³₁∫³ (x² + 3xy) dx dy

We first integrate the first term with respect to x to obtain;

[x³/3 + (3/2)x²y] from x = 0 to x = 3

This gives;

[3³/3 + (3/2)(3²)y] - [0³/3 + (3/2)(0²)y]

= 9 + (27/2)y... equation (1)

Now we can substitute this result into the second term of the double integral to obtain the following single integral;

∫₃₁ 9 + (27/2)y dy

Now we can evaluate the integral as follows;

[9y + (27/2)(y²/2)] from y = 1 to y = 3

This gives;

[9(3) + (27/2)(9/2)] - [9(1) + (27/2)(1/2)]

= 51.75

Therefore, the value of the double integral is 51.75.

The value of the double integral A = ∫₀³ ∫₁³ (x² + 3xy) dx dy is 0.

To compute the double integral of A = ∫₀³ ∫₁³ (x² + 3xy) dx dy, we need to evaluate the integral with respect to x first, and then with respect to y.

Let's start by integrating with respect to x:

∫ (x² + 3xy) dx = (x³/3 + 3x²y/2) + C₁,

where C₁ is the constant of integration.

Now, we can integrate this result with respect to y:

∫₁³ [(x³/3 + 3x²y/2) + C₁] dy

= [(x³/3 + 3x²y/2)y + C₁y] ∣₁³

= [(x³/3 + 3x²y/2)y + C₁y] ∣₁³

= [(x³/3 + 9x²/2) + C₁(3) - (x³/3 + 3x²/2) - C₁(1)]

= [(8x²/3) - (2x³/3)] ∣₁³

= [(8(9)/3) - (2(27)/3)] - [(8(1)/3) - (2(1)/3)]

= [24 - 18] - [8 - 2]

= 6 - 6

= 0.

Therefore, the value of the double integral A = ∫₀³ ∫₁³ (x² + 3xy) dx dy is 0.

Ziehart Pharmaceuticals reported Net Sales of $178,000 and Cost of Goods Sold of $58,000. Candy Electronics Corp. reported Net Sales of $36,000 and Cost of Goods Sold of $26,200. 1. Calculate the gross profit percentage for both companies. (Round your answers to 1 decimal place.) Gross Profit Ziehart Pharmaceuticals Candy Electronics Corp.

Answers

To calculate the gross profit percentage, we need to use the following formula:

Gross Profit Percentage = (Gross Profit / Net Sales) * 100

For Ziehart Pharmaceuticals:

Net Sales = $178,000

Cost of Goods Sold = $58,000

Gross Profit = Net Sales - Cost of Goods Sold

Gross Profit = $178,000 - $58,000

Gross Profit = $120,000

Gross Profit Percentage for Ziehart Pharmaceuticals = (120,000 / 178,000) * 100

Gross Profit Percentage for Ziehart Pharmaceuticals ≈ 67.4%

For Candy Electronics Corp:

Net Sales = $36,000

Cost of Goods Sold = $26,200

Gross Profit = Net Sales - Cost of Goods Sold

Gross Profit = $36,000 - $26,200

Gross Profit = $9,800

Gross Profit Percentage for Candy Electronics Corp = (9,800 / 36,000) * 100

Gross Profit Percentage for Candy Electronics Corp ≈ 27.2%

Therefore, the gross profit percentage for Ziehart Pharmaceuticals is approximately 67.4%, and the gross profit percentage for Candy Electronics Corp is approximately 27.2%.

If a given probability distribution has a mean of 7, a median of 6, a standard deviation of 3, and a variance of 9, what is the expected value

Answers

The expected value is 6.0.

The expected value (or mean) of a probability distribution can be obtained by the formulaµ = E(X) = ∑ xᵢP(xᵢ). The given probability distribution has a mean of 7, a median of 6, a standard deviation of 3, and a variance of 9. Therefore, we can get the expected value using the formulaµ = E(X) = ∑ xᵢP(xᵢ).

Mean = 7Median = 6Standard deviation = 3Variance = 9The formula for variance is:Variance = (Standard deviation)²9 = (3)²Variance = 9The formula for variance can be modified as:

Variance = E(X²) - [E(X)]²Variance + [E(X)]² = E(X²)Substituting the values,9 + 7² = E(X²)E(X²) = 58To find expected value (or mean), the formula is:µ = E(X) = ∑ xᵢP(xᵢ)The median is the value that separates the upper 50% of the distribution from the lower 50%.

The mean is a measure of the central tendency of the distribution. So, the probability distribution is skewed to the right. There are many possible ways to construct a probability distribution with the given mean, median, variance, and standard deviation.

One example of such a probability distribution is shown below:x: 0 1 5 6 9P(x): 0.05 0.1 0.4 0.3 0.15Using the formula µ = E(X) = ∑ xᵢP(xᵢ), the expected value isµ = 0(0.05) + 1(0.1) + 5(0.4) + 6(0.3) + 9(0.15)µ = 0.5 + 2 + 1.8 + 1.35 + 1.35µ = 6.0Thus, the expected value is 6.0.

five cards are dealt at random without replacement from a deck of 52 cards. find the chance that at least one of the suits doesn't appear.

Answers

The chance that at least one of the suits doesn't appear is approximately 0.304 or 30.4%.

Chance of missing a suit

The probability that all four suits appear in a five-card hand is:

(13/52) * (13/51) * (13/50) * (13/49) * (13/48)

The probability that at least one suit doesn't appear is the complement of this event, which is:

1 - (13/52) * (13/51) * (13/50) * (13/49) * (13/48)

Simplifying this expression, we get:

1 - (13/52) * (1 - 1/51) * (1 - 2/50) * (1 - 3/49) * (1 - 4/48)

= 1 - (13/52) * (50/51) * (48/50) * (46/49) * (44/48)

= 1 - 0.696

= 0.304

Therefore, the chance that at least one of the suits doesn't appear is approximately 0.304 or 30.4%.

The approach I used to solve the problem of finding the chance that at least one of the suits doesn't appear is a common one that can be used to solve many similar problems in probability theory. Specifically, we can use the complement rule, which states that the probability of an event occurring is equal to 1 minus the probability of the event not occurring.

This approach can be applied to many problems in probability theory, but it may not always be the most efficient or straightforward method. The choice of method will depend on the specific problem and the information provided. Other common methods include using combinations and permutations, conditional probability, and Bayes' theorem.

what is a polygon with all sides and angles congruent

Answers

A regular polygon is a polygon with all sides and angles congruent. It exhibits symmetry and uniformity in its sides and angles, creating a visually appealing shape.

A polygon with all sides and angles congruent is called a regular polygon. In a regular polygon, all sides have the same length, and all angles have the same measure. This uniformity in the lengths and angles of the polygon's sides and angles gives it a symmetrical and balanced appearance.

Regular polygons are named based on the number of sides they have. Some common examples include the equilateral triangle (3 sides), square (4 sides), pentagon (5 sides), hexagon (6 sides), and so on. The names of regular polygons are derived from Greek or Latin numerical prefixes.

In a regular polygon, each interior angle has the same measure, which can be calculated using the formula:

Interior angle measure = (n-2) * 180 / n

Where n represents the number of sides of the polygon.

The sum of the interior angles of any polygon is given by the formula:

Sum of interior angles = (n-2) * 180 degrees

Regular polygons have several interesting properties. For instance, the

exterior angles of a regular polygon sum up to 360 degrees, and the measure of each exterior angle can be calculated by dividing 360 degrees by the number of sides.

Regular polygons often possess symmetrical properties and are aesthetically pleasing. They are commonly used in design, architecture, and various mathematical applications.

Pythagorean Theorem: a^2 + b^2 = c^2

STEP 1: Define your variables

The legs of the triangle are a and b, and the hypotenuse is c.

a = x

b = 4

c = 14

STEP 2: Plug your variables into the equation and solve

x^2 + 4^2 = 14^2

x^2 + 16 = 196

x^2 + 16 - 16 = 196 - 16

x^2 = 180

\(\sqrt{x^2}\) = \(\sqrt{180}\)

STEP 3: Simplify

Since the question asks you to put the equation in simplified radical form, you do not have to approximate the answer, but you do have to simplify the radical.

What is slope?

The slope of a line, which measures how steep it is, is calculated by dividing the change in the y-axis (vertical direction) by the change in the x-axis (horizontal direction) between any two points on the line.

Now, we shall solve the question by  two-point formula method:-

1. (1, 4) and (3,2)

Slope = (y2 - y1) / (x2 - x1) = (2 - 4) / (3 - 1) = -2/2 = -1

2. (2,5) and (4,-7)

Slope = (y2 - y1) / (x2 - x1) = (-7 - 5) / (4 - 2) = -12/2 = -6

Therefore, the slope of the line passing through (2,5) and (4,-7) is -6.

3. (-5, 3) and (2,7)

Slope = (y2 - y1) / (x2 - x1) = (7 - 3) / (2 - (-5)) = 4/7

Therefore, the slope of the line passing through (-5, 3) and (2,7) is 4/7.

4. (3,-4) and (-2, 8)

Slope = (y2 - y1) / (x2 - x1) = (8 - (-4)) / (-2 - 3) = 12/(-5) = -2.4

Therefore, the slope of the line passing through (3,-4) and (-2, 8) is -2.4.

Answers

Answer:

12545454/100000000

Step-by-step explanation:

To express 0.12545454 in the form of p/q, where p and q are integers, we can follow these steps:

1. Let x = 0.12545454.

2. Multiply x by a power of 10 to remove the repeating decimal part. Since there are two digits repeating, we will multiply by 100 to get rid of the repetition.

  x * 100 = 12.545454.

3. Subtract x from the product obtained in step 2 to eliminate the repeating part.

  100x - x = 12.545454 - 0.12545454 = 12.42.

4. Now, we have the equation 99x = 12.42. Divide both sides by 99 to solve for x.

  x = 12.42 / 99 = 0.125454545...

5. Notice that the decimal part in step 4 is the same as the original decimal part (0.12545454). Therefore, we can express 0.12545454 as a fraction p/q.

  p/q = 0.12545454/1 = 12545454/100000000.

So, 0.12545454 can be expressed in the form of p/q as 12545454/100000000.

Answers

The applicant who should be offered the job based on the aptitude test scores is Reyna. Reyna scored 87 on her version of the test, which has a mean of 73 and a standard deviation of 10.

Demetria scored 301.8 on her version of the test, which has a mean of 288 and a standard deviation of 23. Pierce scored 8.56 on his version of the test, which has a mean of 7.3 and a standard deviation of 0.6. The scores of Reyna, Demetria, and Pierce can be compared by standardizing them and calculating the z-scores. Standardizing involves subtracting the mean from the score and dividing by the standard deviation, resulting in z-scores. This can be used to compare the performance of each applicant relative to their own version of the test. Reyna's z-score is 1.37, Demetria's z-score is 0.86, and Pierce's z-score is 14.27. This shows that Reyna performed better than Demetria, and significantly better than Pierce. Reyna should therefore be offered the job based on her performance on the aptitude test.

A number is 7 more than 5 times another number and their difference is 78 Find the numbers

Answers

Answer:

n = 95.75

m = 17.75

Step-by-step explanation:

n = one number

m = another number

System of Equations:

n = 7+5m

n - m = 78

Substitution Method:

7+5m - m = 78

4m + 7 = 78

4m = 71

m = 17.75

n - 17.75 = 78

n = 95.75

Explain why it is important to be able to perform
matrix operations by hand when a calculator can
do them for you.

Answers

Answer:

The answer is explained below

Step-by-step explanation:

I am going to list a series of points where it is important to learn how to perform matrix operations.

1. The first and most important is that calculators may not always be available, and even if you do have them there will be cases where they won't let you use them.

2. By performing the operation by hand it will allow you to understand the process in a better way, such as finding an inverse, if you do this with a calculator you will most likely not know what was done.

3. Although it seems basic, some calculators cannot display the elements of a matrix as fractions, which is important to understand the process.

4. There are special cases such as when an array could contain a variable and the calculator could not be used in this case.

5. Although in most cases the calculator can help us get out of the operation quickly, sometimes it is faster at hand and, most importantly, when performing the step by step, you understand the entire operation better.

INCLUDE:

Calculators may not always be available.

Finding an inverse by hand allows me to understand the process.

Calculators may not show the elements of a matrix as fractions.

Sometimes it is faster by hand.

A matrix could contain a variable.
