Answers

Answer 1

The base of the parallelogram is 18. 3 feet

How to determine the base of the parallelogram

From the information given, we have that;

Area = 280ft^2

height = 5x

Base = 6x

Note that he formula that is used for calculating the area of the parallelogram is represented with the equation;

Area = bh

Given that the parameters are;

b is the base of the parallelogramh is the height of the parallelogram

Substituting the values of area, base and height.

280 = 5x × 6x

280 = 30x^2

Divide both sides by 30

x^2 = 280/30

Find the square root of both sides

x = √(280/30)

We have that the base = 6x

Substitute the value of x, we get;

Base = 6x = 6(√(280/30))

Base = 18.3ft

Work out the value of x and the value of y in the simultaneous equations below. 4x + 7y = 40 - 4x + 4y = 4​

Answers

The solution for the simultaneous of equations 4x + 7y = 40 and 4x + 4y = 4 by elimination are x = -11, y = 12

How to evaluate for the solutions of the equations by elimination

we shall write the equations as:

4x + 7y = 40...(1)

4x + 4y = 4...(2)

subtract equation (2) from (1) to eliminate x

4x + 7y - 4x - 4y = 40 - 4

3y = 36

divide through by 3

y = 12

put the value 12 for y in equation (1) to get

4x + 7(12) = 40

4x + 84 = 40

4x = 40 - 84 {subtract 84 from both sides}

4x = -44

divide through by 4;

x = -11

Therefore, the solution for the simultaneous of equations 4x + 7y = 40 and 4x + 4y = 4 by elimination are x = -11, y = 12

The distance between new orleans and houston is 353 miles. At 12:20pm, a bus leaves houston for new orleans at a speed of 60mph. 45 minutes late, a motorcycle leaves new orleans for houston at a speed of 72mph. At what time will the bus and the motorcycle pass each other if neither stops or changes speed?

Answers

As per the given distance, the bus and the motorcycle will pass each other at 4:50 pm.

Now, let's find the distance the bus travels during that time. We know the speed of the bus is 60 mph, so we can use the formula distance = speed x time. Thus, the distance the bus travels is:

distance = speed x time

distance = 60 x t

Next, let's find the distance the motorcycle travels during the same time. The speed of the motorcycle is 72 mph, so we can use the same formula to find the distance the motorcycle travels:

distance = speed x time

distance = 72 x (t - 3/4)

Here, we subtract 3/4 from the time because the motorcycle leaves 45 minutes later than the bus. Remember, we need to convert 45 minutes to hours by dividing it by 60. Therefore, 45 minutes is equal to 3/4 of an hour.

Now that we have both distances, we can set them equal to each other since the bus and the motorcycle will meet at the same point in time:

60t = 72(t - 3/4)

Let's simplify and solve for "t":

60t = 72t - 54

12t = 54

t = 4.5

Therefore, it will take 4.5 hours for the bus and the motorcycle to meet each other. But, we need to find out what time that will be. We know the bus left at 12:20 pm, so we add 4.5 hours to that time:

12:20 pm + 4.5 hours = 4:50 pm

a reaseacher tests the null hypothesis that the mean body temperature of residents in a nursing home is 98.6 f. which statistical test could the researcher use?

Answers

The statistical test that a researcher could use to test the null hypothesis that the mean body temperature of residents in a nursing home is 98.6°F is a one-sample t-test.

What is a statistical test?

A statistical test is a method that enables the comparison of the collected data with the assumed distribution of the data. A statistical test aids in determining if the outcomes of the experiment or research are caused by the treatment or if they are due to the random variation in the data.

A null hypothesis is a type of hypothesis that predicts the absence of a relationship between variables or groups. The null hypothesis claims that no difference exists between two variables or groups, and that any observed differences are due to chance.

Alternative hypotheses are used to reject null hypotheses, as they predict the presence of a relationship between variables or groups.

The significance level, which is the probability of committing a Type I error, is often used to set the null hypothesis. The statistical test that a researcher could use to test the null hypothesis that the mean body temperature of residents in a nursing home is 98.6°F is a one-sample t-test.

The t-test will aid in determining if the difference between the mean body temperature of residents in the nursing home and 98.6°F is statistically significant.

Standard deviation is a statistical measure that describes the amount of variation or dispersion of a set of data from its mean or average value. In other words, it measures how much the data is spread out from the central tendency. It is calculated as the square root of the variance, which is the average of the squared differences between each data point and the mean.

The standard deviation is expressed in the same units as the data and is typically denoted by the symbol σ. A small standard deviation indicates that the data points are clustered around the mean, while a large standard deviation indicates that the data points are widely spread out from the mean.

Write a quadratic equation that goes through the points (0,5), (2,1), and (1,2). y = ax^2 + bx + c

Answers

To write a quadratic equation that goes through the points (0,5), (2,1), and (1,2), we can use the fact that a quadratic equation has the form:

y = ax^2 + bx + c

We can substitute the coordinates of each point into this equation to get a system of three equations in the three unknowns a, b, and c. We can then solve this system to find the values of a, b, and c.

Substituting (0,5) into the equation, we get:

5 = a(0)^2 + b(0) + c
5 = c

Substituting (2,1) into the equation, we get:

1 = a(2)^2 + b(2) + c
1 = 4a + 2b + 5

Substituting (1,2) into the equation, we get:

2 = a(1)^2 + b(1) + c
2 = a + b + 5

Now we have a system of three equations:

5 = c
1 = 4a + 2b + 5
2 = a + b + 5

Solving this system, we get:

a = -2
b = 8
c = 5

Therefore, the quadratic equation that goes through the points (0,5), (2,1), and (1,2) is:

y = -2x^2 + 8x + 5

The coefficient of variation is a better measure of risk than the standard deviation if the expected returns of the securities being compared differ significantly.
A. True
B. False

Answers

True. The coefficient of variation is a better measure of risk than the standard deviation if the expected returns of the securities being compared differ significantly.

The coefficient of variation (CV) is a relative measure of risk that takes into account the standard deviation and the mean of a distribution. It is a better measure of risk than the standard deviation when comparing securities with significantly different expected returns because it adjusts for the differences in the means.

The CV is calculated as the ratio of the standard deviation to the mean, and it allows for the comparison of the risk of investments with different expected returns on a standardized basis. Therefore, it is a useful tool for investors who want to compare the risk of investments that have different levels of expected returns. However, it should be noted that the CV has limitations and should not be the sole measure of risk used in investment analysis.

Use a triple integral to find the volume of the given solid The tetrahedronenclosed by the coordinate planes and the plane 10x y z 4

Answers

The volume of the tetrahedron is 1.0667 cubic units.

The tetrahedron is enclosed by the coordinate planes and the plane 10x + y + z = 4.

To find the volume of the tetrahedron using a triple integral, we can use the following bounds:

0 ≤ z ≤ 4 - 10x - y

0 ≤ y ≤ 4 - 10x

0 ≤ x ≤ 0.4

This is because the tetrahedron is bound by the coordinate planes, so x, y, and z all must be positive, and the plane 10x + y + z = 4 sets the upper bound for z and y, and the upper bound for x is simply where the plane intersects the x-axis (which can be found by setting y and z equal to 0 and solving for x).

The triple integral to find the volume of the tetrahedron is then:

V = ∫∫∫ dV = ∫0^0.4 ∫0^(4-10x) ∫0^(4-10x-y) dz dy dx

Evaluating this integral, we get:

V = ∫0^0.4 ∫0^(4-10x) (4-10x-y) dy dx

= ∫0^0.4 [4y - 10xy - (1/2)y^2]0^(4-10x) dx

= ∫0^0.4 [4(4-10x) - 10x(4-10x) - (1/2)(4-10x)^2] dx

= ∫0^0.4 (-25x^2 + 20x + 8) dx

= [-25/3 x^3 + 10 x^2 + 8x]0^0.4

= 1.0667

Therefore, the volume of the tetrahedron is approximately 1.0667 cubic units.

At the age of 30, Jasmine started a retirement account with $50,000 which compounded interest semi-annually with an interest rate of 1. 75%. She made no further deposits. After 25 years, she decided to withdraw 50% of what had accumulated in the account so that she could con- tribute towards her grandchild's college education. She had to pay a 10% penalty on the early withdrawal. What was her penalty?

Answers

Jasmine's penalty for the early withdrawal from her retirement account was approximately $3,702.50.

The formula to calculate the compound interest is:

[tex]A = P(1 + r/n)^{n \times t}[/tex]

Where:

A = the final amount after t years

P = the principal amount (initial investment) ($50,000 in this case)

r = the annual interest rate (1.75% in decimal form, so 0.0175)

n = the number of times interest is compounded per year (semi-annually, so 2)

t = the number of years (25 years in this case)

Let's calculate the final amount accumulated in the account:

[tex]A = 50000 \times (1 + 0.0175/2)^{2\times 25}[/tex]

[tex]A = 50000 \times (1.00875)^{50}[/tex]

A = 50000 × 1.481

A = $74,050

After 25 years, Jasmine has approximately $74,050 in her retirement account.

Now, she decides to withdraw 50% of that amount:

Withdrawal Amount = 0.5 × $74,050

Withdrawal Amount = $37,025

Finally, she had to pay a 10% penalty on the early withdrawal:

Penalty = 0.10×$37,025

Penalty = $3,702.50

Consider the marked interior angles in the regular pentagon and the concave pentagon in the following image, and then answer the questions below.


a. After looking at the sum of the angle measures of these polygons, what would you guess would be the sum of the interior angles of a
17-gon? Explain your reasoning.
b. What would you guess would be the sum of the interior angles of a
concave 17-gon? Explain your reasoning.
c. In your own words, explain why the sum of the exterior angles of any
convex polygon always equals 360°.
d. What would you guess would be the sum of the exterior angles of a
concave polygon? Explain your reasoning.

Answers

Answer:

a. The sum of the interior angles of a regular polygon with n sides can be found using the formula (n-2) x 180 degrees. Using this formula, we know the sum of the interior angles of a pentagon is (5-2) x 180 = 540 degrees. Since the sum of the interior angles of a polygon increases by 180 degrees for each additional side, we can guess that the sum of the interior angles of a 17-gon would be (17-2) x 180 = 2700 degrees.

b. For concave polygons, the sum of the interior angles may not follow the same pattern as that of regular polygons. It is possible for the sum of the interior angles of a concave polygon to be greater or less than the sum of the interior angles of a regular polygon with the same number of sides. So, it is difficult to make an accurate guess without more information about the specific shape of the concave 17-gon.

c. The sum of the exterior angles of any convex polygon always equals 360 degrees because each exterior angle is supplementary to its adjacent interior angle. In other words, the exterior angle and the adjacent interior angle form a straight line, which is 180 degrees. Since there are n exterior angles in an n-sided polygon, the sum of all the exterior angles is n x 180 degrees. However, each exterior angle is counted once for each vertex, and there are n vertices, so we need to divide by n to get the total sum of exterior angles, which is (n x 180) / n = 180 degrees.

d. For a concave polygon, the sum of the exterior angles may be greater than or less than 360 degrees, depending on the shape of the polygon. In a concave polygon, some of the exterior angles will be greater than 180 degrees, which means that their adjacent interior angles will be less than 180 degrees. Since the sum of the exterior angles is equal to the sum of the adjacent interior angles, some of the exterior angles will need to be subtracted from 360 degrees to get the total sum of exterior angles. However, without more information about the specific shape of the concave polygon, it is difficult to make an accurate guess.

Answer:

a. The sum of the angle measures of the regular pentagon is 540 degrees, and the sum of the angle measures of the concave pentagon is 720 degrees. Both of these polygons have five sides. If we assume that the sum of the angle measures of a polygon with n sides is proportional to n, we can use the ratios of the number of sides in each polygon to make an estimate for the sum of the interior angles of a 17-gon. The ratio of the number of sides in a 17-gon to the number of sides in a regular pentagon is 17/5. If we multiply the sum of the angle measures of the regular pentagon by this ratio, we get an estimate for the sum of the angle measures of a 17-gon:

540 * (17/5) = 1836 degrees.

So, we would guess that the sum of the interior angles of a 17-gon is 1836 degrees.

b. We can use a similar reasoning as in part (a) to estimate the sum of the interior angles of a concave 17-gon. The ratio of the number of sides in a concave pentagon to the number of sides in a concave 17-gon is 5/17. If we multiply the sum of the angle measures of the concave pentagon by this ratio, we get an estimate for the sum of the angle measures of a concave 17-gon:

720 * (5/17) = 211.76 degrees.

So, we would guess that the sum of the interior angles of a concave 17-gon is 211.76 degrees.

c. The sum of the exterior angles of a convex polygon always equals 360 degrees because the exterior angle at each vertex of the polygon is equal to the sum of the two adjacent interior angles. If we add up all of the exterior angles of a polygon, we are essentially adding up all of the vertex angles twice (once for each adjacent exterior angle). Therefore, the sum of the exterior angles of a convex polygon is equal to 2 times the sum of the interior angles. Since the sum of the interior angles of any n-sided polygon is (n-2)*180 degrees, the sum of the exterior angles is:

2 * (n-2) * 180 = 360(n-2) degrees.

d. It is not possible to make a generalization about the sum of the exterior angles of a concave polygon, because the sum of the exterior angles of a concave polygon can be greater than, less than, or equal to 360 degrees, depending on the polygon's shape. The sum of the exterior angles of a concave polygon can be greater than 360 degrees if the polygon has one or more reflex angles, which are angles greater than 180 degrees. In this case, the exterior angle at each vertex is less than the adjacent interior angle, so the sum of the exterior angles is greater than 360 degrees. On the other hand, if a concave polygon has no reflex angles, the sum of the exterior angles will be less than 360 degrees.

In problem 13.2, we can use the power method to determine the highest eigenvalue and corresponding eigenvector for the matrix:

|2-x 8 10|

| 8 4-x 5 |

|10 5 7-x|

We start by assuming a random initial vector, say v0, and then repeatedly multiplying it by the matrix A and normalizing the resulting vector, until the vector converges to the eigenvector corresponding to the highest eigenvalue.

For problem 13.3, we can use a similar approach to determine the lowest eigenvalue and corresponding eigenvector. However, instead of multiplying by A, we multiply by A^-1. This is because the lowest eigenvalue is the reciprocal of the highest eigenvalue, and the corresponding eigenvector remains the same.

Both problems require us to perform the power method until the resulting vector converges to the desired eigenvector. The number of iterations required for convergence depends on the matrix A and the initial vector v0.

The yellow band has a surface area of 20x + 100 square inches.

The area of the yellow band is the difference between the area of the yellow square and the area of the orange square.

The yellow square has a side length of (x + 10) inches, where 10 inches is the sum of the widths of the two yellow bands that border the orange square.

So the area of the yellow square is:

A_ yellow = (x + 10)²

The orange square has a side length of x inches, so its area is:

A_ orange = x²

The area of the yellow band is the difference between these two areas:

A_ band = A_ yellow - A_ orange

= (x + 10)² - x²

= x² + 20x + 100 - x²

= 20x + 100

Therefore, the area of the yellow band is 20x + 100 square inches.

A solid square-based pyramid 1 is divided into two parts: a square-based pyramid 2 and a frustum 3.

Pyramid 1 has a base of side length 8 cm.
Pyramid 2 has a base of side length 2 cm.
The perpendicular height of pyramid 1 is 10 cm.

Frustum 3 is made from a material with a density of 4.2g/cm^3

Work out the mass of the frustum,

Answers

The mass of the frustum is 784kg

What is a frustum?

Remember that a frustum is a unique 3D object that is derived by cutting the apex of a cone or a pyramid.

We should know that since pyramid 1 and pyramid 2 are similar,

The perpendicular height of pyramid 2 is 10*4/8 = 5cm

So the volume of [pyramid 1 is =V₁ = 1/3*8²*10 = 640/3 cm³

The voluume of pyramid 2 V₂ = 1/3*4²*5 = 40/3 cm³

So the volume of frustum is 640/3 cm³ - 40/3 cm³ = 560/3 cm³

Recall mass = density*volume

So the mass is = 560/3 * 42 = 784g

The number of bacteria in a culture is growing at a rate of 3,000e^(2t/5) per unit of time t. At t=0, the number of bacteria present was 7,500. Find the number present at t=5.a. 1.200 e^2b. 3,000 e^2c. 7,500 e^2d. 7,500 e^5e. 15.000/7 e^7

Answers

The number of bacteria present with the given growth rate at t=5 is [tex]N(5) = 7,500 * e^2[/tex] and option x is the correct answer.

What is exponential growth?

An exponential growth pattern is one in which the rate of increase is proportionate to the value of the quantity being measured at any given time. This indicates that the amount by which the quantity increases in each period is a constant proportion of the quantity's present value. Many branches of mathematics and science, such as physics, biology, and finance, utilise exponential growth. Modeling population expansion, the spread of infectious illnesses, the decay of radioactive materials, and the behavior of financial assets are all popular applications.

Given that, the number of bacteria present was 7,500.

The exponential growth is given by the formula:

[tex]N(t) = N(0) * e^{(kt)}[/tex]

Substituting the values N(0) = 7,500 and the growth rate is k = 2/5 we have:

[tex]N(5) = 7,500 * e^{(2/5 * 5)}\\N(5) = 7,500 * e^2[/tex]

Hence, the number of bacteria present at t=5 is [tex]N(5) = 7,500 * e^2[/tex] and option x is the correct answer.

You have a circular loop of wire in the plane of the page with an initial radius of 0.40 m which expands to a radius of 1.00 m. It sits in a constant magnetic field B = 24 mT pointing into the page. Assume the transformation occurs over 1.0 second and no part of the wire exits the field. Also assume an internal resistance of 30 Ω. What average current is produced within the loop and in which direction? Express your answer with the appropriate units. Enter positive value if the current is clockwise and negative value if the current is counterclockwise. My INCORRECT work: emf = -BAcos(theta)/dt emf = -B*1*(dA/dt) emf = -B*pi*(2*(expansion rate/1)^2*t+2*r0*(expansion rate/1) Then V=IR so emf=IR so I=emf/R I = -[B*pi*(2*(expansion rate/1)^2*t+2*r0*(expansion rate/1)]/R I = -[24x10^-3*pi*(2*.6^2*1+2*.4*.6)]/30 I ~ -3.015928947x10^-3 I ~ -3.0x10^-3 Which is wrong.

Answers

In the given scenario, the average current produced within the loop is approximately 2.13 A.

We can begin by computing the change in magnetic flux across the loop as it expands to determine the average current generated within the loop.

The following equation provides the magnetic flux across a loop:

Φ = B * A * cos(θ)

ΔΦ = B * ΔA

ΔA = A₂ - A₁ = π * (1.00 m)² - π * (0.40 m)² = π * (1.00² - 0.40²) = π * (1.00 + 0.40)(1.00 - 0.40) = π * (1.40)(0.60) = 0.84π m²

So,

ΔΦ = B * ΔA = (24 mT) * (0.84π m²) = 20.25π m²·T

emf = ΔΦ / Δt = (20.25π m²·T) / (1.0 s) = 20.25π V

As:

emf = I * R

So, again

I = emf / R = (20.25π V) / (30 Ω) ≈ 2.13 A

Thus, the average current produced within the loop is approximately 2.13 A.

d. AB ≅ DE because they are corresponding parts of similar triangles.

Answers

the triangles are similar, corresponding parts of the triangles are equal in measure. Thus, it is reasonable to conclude that [tex]AB ≅ DE.[/tex]

It is reasonable to conclude that [tex]AB ≅ DE[/tex]because triangles ABC and DEF are similar.

This means that corresponding parts of the two triangles are equal in measure. Specifically, ∠A and ∠D are equal in measure, as are ∠B and ∠E.

Therefore, the corresponding sides AB and DE are equal in measure.

A way to show that the two triangles are similar is by using the AA Similarity Postulate.

This postulate states that if two angles of one triangle are equal in measure to two angles of a second triangle, then the two triangles are similar. In this case, [tex]∠A ≅ ∠D and B ≅ ∠E[/tex], which means the two triangles are similar.
