Answers

Answer 1

The solutions are explained below.

Given that, Jeremy and Leslie are each flying their own drones in a flat field with their drones hovering between the two of them. The figure is attached.

Height of Jeremy's drone = 30 m

Height of Leslie's drone = x m

h / 70 = sin 53°

h = 70 × sin 53°

h = 57.34

Therefore, Leslie's drone is higher than Jeremy's drone.

Difference of height = 57.34 - 30 = 27.34 m

27.34 / x = tan25°

x = 58.63 m

Average:

The term "average" generally refers to the arithmetic mean, which is a measure of central tendency calculated by adding up all the values in a dataset and then dividing by the total number of values.

Hence the formula used to calculate the average is

Average = [ Sum of observations]/ No of observations

Here we have

A student scored 98, 94, 96, and 88 points out of 100 on the last 4 tests.  

Here we need to at what score the average will be 94

Let x be the score the student got on 5 th test and the average is 94

Using the formula,

Average of the 5 test scores = [ 98 + 94 + 96 + 88 + x ]/ 5

As we assumed the average is 94

=>  [ 98 + 94 + 96 + 88 + x ]/ 5 = 94

A ship is traveling at 13 knots bearing 305° from New York. How fast is the ship traveling south?

Answers

Answer:

To find the speed of the ship traveling south, we need to find the component of its velocity in the south direction.

The angle between the ship's velocity vector and the south direction is the complement of the angle between the ship's velocity vector and the east direction (which is 90° - 305° = 55°).

So, the southward component of the ship's velocity is:

sin(55°) x 13 knots ≈ 10.62 knots

Therefore, the ship is traveling south at approximately 10.62 knots.

z=

Answers

We know that z varies directly as √√x and inversely as y, which can be written as:

z = k(√√x)/y

where k is the constant of proportionality.

To find the value of k, we can use the values given when x = 25 and y = 7:

179 = k(√√25)/7

179 = k(5/7)

k = (179*7)/5

k = 250.6

Now we can use this value of k to find z when x = 64 and y = 4:

z = 250.6(√√64)/4

z = 250.6(2)/4

z = 125.3

Therefore, z ≈ 125.3 when x = 64 and y = 4.

(C) The automobile would be worth $5,844.24 in 2007.

What is depreciation?

Depreciation is an annual income tax deduction that enables you to recoup the purchase price or other basis of a specific item over the course of its use.

It is a provision for the property's normal wear and tear, degeneration, or obsolescence.

As the years pass, the car's value drops.

This process is known as depreciation.

Depreciation is the decrease in asset value brought on by normal wear and tear.

Use this formula to calculate the annual rate of change:

g = (FV/PV)¹⁾ⁿ - 1

Now, using the formula calculate as follows:

(11000/3900)¹⁾⁸ - 1

-0.1463 = -14.63%

The following formula can be used to estimate a car's worth in 7 years:

FV = P (1 + g)ⁿ

$39,000 x (1 - 0.1463)¹²

$39,000 x 0.8537¹² = $5,844.24

Therefore, (A) between 1995 and 2003, there was a change at an annual rate of -0.1463

A community college has 1400 parking spots on campus. When it builds its new​ library, the college will lose 63 of its parking spots. What will be the percent decrease in the number of available parking​ spots?

Answers

According to the question we can conclude that the percent decrease in the number of available parking spots is 4.5%.

What is percentage?

In mathematics, a percentage is a number or ratio that's also expressed as just a fraction from 100. Occasionally, the acronyms "pct.," "pct," as well as "pc" are also used. Yet it is commonly indicated by the percent sign, "%." The % amount has no dimensions. Percentages are essentially fractions when the denominator is 100. Use the percent sign (%) to indicate that what a number is just a percentage by placing it next to it. For instance, you score a 75% if you properly answered 75 out of questions in total on something like a test (75/100). Divide the money even by total as well as multiply the outcome by 100 to calculate percentages. The formula for calculating the percentage is (value/total) x 100%.

Given,

To find the percent decrease in the number of available parking spots, we need to calculate the difference between the initial number of parking spots and the new number of parking spots, and express it as a percentage of the initial number of parking spots.

The initial number of parking spots is 1400, and the new number of parking spots after the library is built is 1400 - 63 = 1337.

The difference between the initial number of parking spots and the new number of parking spots is 1400 - 1337 = 63.

To express this difference as a percentage of the initial number of parking spots, we divide the difference by the initial number and multiply by 100:

(63 / 1400) x 100 = 4.5%

Therefore, the percent decrease in the number of available parking spots is 4.5%.

The y-intercept is where the line crosses over the y-axis. In this case, there is a point on 6, which means 6 is our y-intercept.

Next, we need to calculate the slope. We know slope = rise/run.

Start at the point -9,3. We rise 5 and go left 1 to get to the point -4,2.

Since we went left, our slope is 5/-1, which simplifies to -5.

or What is the surface area of this cylinder? Use ​ ≈ 3.14 and round your answer to the nearest hundredth. 8 ft 6 ft square feet

Answers

The surface area of the cylinder has a radius of 8cm and a height of 6cm is 703.36 square feet.

To calculate the surface area of a cylinder, we need to add the area of the top and bottom circles to the area of the curved side.

The formula for the area of a circle is:

A = [tex]\pi r^2[/tex]

where A is the area, π (pi) is a mathematical constant approximately equal to 3.14, and r is the radius.

The formula for the curved surface area of a cylinder is:

C = 2πrh

where C is the curved surface area, r is the radius, and h is the height of the cylinder.

Given that the radius is 8cm and the height is 6cm, we can calculate the surface area as follows:

Area of top circle =

Area of bottom circle =[tex]\pi r^2[/tex] = 3.14 x [tex]8^2[/tex] = 200.96 cm square

Curved surface area = 2πrh = 2 x 3.14 x 8 x 6 = 301.44 cm square

Therefore, the total surface area of the cylinder is:

Total surface area = Area of top circle + Area of bottom circle + Curved surface area

Total surface area = 200.96 [tex]cm^2[/tex] + 200.96 [tex]cm^2[/tex] + 301.44 [tex]cm^2[/tex]

What is circle?

A circle is a particular type of ellipse in mathematics or geometry where the eccentricity is zero and the two foci are congruent. A circle is also known as the location of points that are evenly spaced apart from the centre. The radius of a circle is measured from the centre to the edge. The line that splits a circle into two identical halves is its diameter, which is also twice as wide as its radius.

A circle is a fundamental 2D form whose radius is quantified. The interior and exterior parts of the aircraft are separated by the circles. It resembles a line segment in several ways.

For the given circle B, the measure of angle ABC is 46 degrees.

Suppose he got dilates the rectangle shown below with the center of dilation at 0,0 and a scale factor of 2, and then translates the figure 1 unit to the left. What will be the coordinates of the vertices of the similar figure that results

Answers

The vertices of the similar figure that results from the dilation and translation will be A'' = (2a - 1, 2b), B'' = (2c - 1, 2b), C'' = (2c - 1, 2d), and D'' = (2a - 1, 2d).

Assume that the rectangle's four vertices are A, B, C, and D, with the corresponding coordinates being (a, b), (c, b), (c, d), and (a, d).

First, enlarge the rectangle.

We must multiply the coordinates of each vertex by the scale factor of two in order to enlarge the rectangle. We can apply the following formulas because the centre of dilation is at (0, 0):

Old x-coordinate + 2 equals the new x-coordinate

Old y-coordinate + 2 times the new y-coordinate

Therefore, following dilation, the new coordinates for the vertices will be: A' = (2a, 2b)

B' = (2c, 2b)

C' = (2c, 2d)

D' = (2a, 2d)

Translate the Figure in Step 2

The x-coordinate of each vertex must be reduced by one in order to translate the figure one unit to the left. Therefore, following translation, the vertices' new coordinates will be: A' = (2a - 1, 2b)

B'' = (2c - 1, 2b)

C'' = (2c - 1, 2d)

D'' = (2a - 1, 2d)

As a result, A'' = (2a - 1, 2b), B'' = (2c - 1, 2b), C'' = (2c - 1, 2d), and D'' = (2c - 1, 2d) will be the vertices of the similar figure that comes from the dilation and translation. (2a - 1, 2d).

The company with the smaller standard deviation The company with the larger standard deviation b. Why is this the better choice?

Answers

Answer:

If the average rates of return are the same for both companies, but one company has a much larger standard deviation of its rates of return. You should invest in a company with a smaller standard deviation.

This is the better choice because a larger standard deviation means that the company's returns are more variable, which implies more risk. While higher risk can result in higher returns, it can also result in significant losses. Investing in a company with a smaller standard deviation of its rates of return will likely result in a more stable return on investment and therefore be a safer investment.

In general, investors should consider both the average and variability returns when making investment decisions. While higher average returns are desirable, they may not be worth the additional risk if the variability of returns is too high.

1. Find a common denominator for 1/3 and 1/12 by dividing each whole into the same number of equal parts.

Answers

Answer: To find a common denominator for 1/3 and 1/12, we need to divide each whole into the same number of equal parts. The denominator of 1/3 represents three equal parts, so we can divide the whole into three parts. The denominator of 1/12 represents twelve equal parts, so we can divide the whole into twelve parts.

The smallest number of parts that both 3 and 12 divide into evenly is 12. So, we can represent 1/3 as 4/12 by dividing each of the three equal parts into four smaller equal parts. And we can represent 1/12 as 1/12 by dividing each of the twelve equal parts into one smaller equal part.

Therefore, a common denominator for 1/3 and 1/12 is 12, and we can rewrite the fractions as:

After answering the presented question, we can conclude that angles  m/CQW = 180° - 125° - 50° => m/CQW = 5° Therefore, m/CQW = 5°.

what are angles?

An angle is a shape in Euclidean geometry that is made up of two rays that meet at a point in the middle known as the angle's vertex. Two rays may combine to form an angle in the plane where they are located. When two planes collide, an angle is generated. They are referred to as dihedral angles. An angle in plane geometry is a possible configuration of two radiations or lines that express a termination. The word "angle" comes from the Latin word "angulus," which meaning "horn." The vertex is the place where the two rays, also known as the angle's sides, meet.

The measure of an inscribed angle is half the measure of its intercepted arc, according to the inscribed angle theorem.

Because C and Q are on the same diameter MQ, m/CQM = 90°. As a result, the intercepted arc CZQ measures 180° - 90° = 90°.

Similarly, because W and Q are on the CW diameter, we have m/CWQ = 90°. As a result, the intercepted arc WVQ measures 180° - 90° = 90°.

m/CQW = 180° - m/CVQ - m/ZVW

m/CQW = 180° - 125° - 50°

When diagonalizing Matrix A = PDP^(-1) and λ1 = (1 + √5)/2 and λ2 = (1 - √5)/2 are the eigenvalues of A, and [0 1] is an eigenvector associated with both λ1 and λ2.

How to diagonalize the matrix A

To diagonalize a matrix, we need to find its eigenvalues and eigenvectors. Let's begin by finding the eigenvalues of A.

The characteristic equation is given by:

det(A - λI) = 0

where I is the identity matrix and λ is the eigenvalue.

For matrix A, we have:

A - λI = [1 - λ 0 ]

[6 -1 - λ]

det(A - λI) = (1 - λ)(-1 - λ) - 6(0) = λ^2 - λ - 1 = 0

Using the quadratic formula, we find that the eigenvalues are:

λ1 = (1 + √5)/2

λ2 = (1 - √5)/2

Now let's find the eigenvectors associated with each eigenvalue. For λ1 = (1 + √5)/2, we have:

(A - λ1I)x = 0

[1 - λ1 0] [x1] = [0]

[6 -1 - λ1] [x2] [0]

which simplifies to:

[-(√5-1)/2 0] [x1] = [0]

[6 -√5-1] [x2] [0]

From the first row, we have x1 = 0. Substituting this into the second row, we get:

(√5+1)x2 = 0

Since x2 cannot be zero (otherwise the eigenvector would be the zero vector), we have:

x2 = 1

Therefore, the eigenvector associated with λ1 is:

v1 = [0 1]

Similarly, for λ2 = (1 - √5)/2, we have:

(A - λ2I)x = 0

[1 - λ2 0] [x1] = [0]

[6 -1 - λ2] [x2] [0]

which simplifies to:

[-(√5+1)/2 0] [x1] = [0]

[6 -√5+1] [x2] [0]

From the first row, we have x1 = 0. Substituting this into the second row, we get:

(√5-1)x2 = 0

Again, since x2 cannot be zero, we have:

x2 = 1

Therefore, the eigenvector associated with λ2 is:

v2 = [0 1]

Now we can use the eigenvectors to diagonalize the matrix. The diagonal matrix D will have the eigenvalues on the diagonal and zeros elsewhere. The matrix P will have the eigenvectors as columns.

D = [λ1 0]

[0 λ2]

P = [v1 v2] = [0 0]

[1 1]

To check that this is the correct diagonalization, we can verify that:

A = PDP^(-1)

where P^(-1) is the inverse of P. Since P is not invertible (the columns are linearly dependent), we can use the pseudoinverse instead:

A = PD†P

where D† is the pseudoinverse of D. We have:

we have diagonalized A as:

A = PDP^(-1)

where:

D = [λ1 0]

[0 λ2]

P = [v1 v2] = [0 0]

[1 1]

and λ1 = (1 + √5)/2 and λ2 = (1 - √5)/2 are the eigenvalues of A, and [0 1] is an eigenvector associated with both λ1 and λ2.

Question 9
Use algebra to show that 4.57 (5 and 7 recurring) equal 4 and 19/33

Answers

o show that 4.57 (5 and 7 recurring) is equal to 4 and 19/33, we can use algebraic equations. First, let x = 4.57 (5 and 7 recurring), then we multiply both sides by 100 to get 100x = 457.5757... Next, we subtract x from 100x to get 99x = 453. Thus, x = 453/99. We can simplify this fraction by dividing both the numerator and denominator by 3, giving us 151/33. Finally, we can write 151/33 as a mixed number, which is 4 and 19/33. Therefore, we have shown that 4.57 (5 and 7 recurring) is equal to 4 and 19/33 using algebraic equations.

which symbols are represented by a closed circle on a number line?

Answers

Answer:

A closed circle on a number line represents an inclusive boundary, meaning that the endpoint is included in the set of values being represented. For example, if a closed circle is placed at the number 2 on a number line, it means that 2 is included in the set of values being represented. In interval notation, this would be written as [2, ...).

Consider the following system of two linear equations:

3y + 2x = 15
x – y = 0

Select the graph that correctly displays this system of equations and point of intersection.

Answers

The answer is x = 3 y=3. This can be solved by reorganising the equation 2x + 3y = 15, x-y=0.

What is Multiplication Zero Property?

This property is true for all real numbers, including integers, fractions, decimals, and any other real number. The Multiplication Zero Property states that the product of any number and zero is equal to zero.

Reorganising the equation:

2x + 3y = 15

x-y=0

To find the solution, multiply both parts of the equation by a multiplier, as in 2x+3y=15.

2(x-y)=0 x 2

Utilize the multiplicative distributional rule.

2x+3y=15

2x-2y=0 x 2

Application of the Multiplication Zero Property

2x+3y=15

2x-2y=0

Separate the two formulas: 2x+3y-(2x-2y)=15-0

2x+3y-2x+2y=15

Take the parentheses off

3+2=15

Expressions combined: 5y=5

Multiply both sides of the equation by the value of the variable: y = 15/5

Take out the joining piece. y=3

Substitute 0 for 2x-2x-2x in one of the computations.

2x-6=0 is used to determine the product.

In the calculation, 6 should be shifted to the left: 2x=6

Add the variable's value to both ends of the equation, then subtract it:

x = 6/2

Take out the intermediary: 2 = 3

The  answer is x = 3 y=3.

unit 3 homework 7 point slope form: Need answers for front and back

Answers

the equation of the line that passes through the 7 points (1, 3), (2, 5),

(3, 7), (4, 9), (5, 11), (6, 13), and (7, 15) is y = 2x + 1.

The point-slope form of a linear equation is a way to write the equation of a line when you have a known point on the line and the slope of the line. The point-slope form is written as:

[tex]y - y_{1} = m(x - x_{1} )[/tex]

where m is the slope of the line, and (x1, y1) is the known point on the line.

The 7-point slope form is a variation of the point-slope form that requires knowing 7 points on the line, rather than just one. It is written as:

[tex](y - y_{1} ) = ((y_{2} - y_{1} ) / (x_{2} - x_{1} ))(x - x_{1} )[/tex]

where[tex](x_{1} , y_{1} ) and (x_{2} , y_{2} )[/tex] are two points on the line with known coordinates, and m is the slope of the line, which can be calculated using the two points.

To use the 7-point slope form to write the equation of a line, you need to know the coordinates of 7 points that lie on the line. Once you have these coordinates, you can choose any two of them to use as [tex](x1, y1) and (x2, y2)[/tex] in the formula, and then solve for the slope m. Once you have the slope, you can plug in the coordinates of any one of the 7 points into the 7-point slope form to find the equation of the line.

For example, let's say we have the following 7 points on a line: (1, 3), (2, 5), (3, 7), (4, 9), (5, 11), (6, 13), and (7, 15).

We can choose any two of these points to use as[tex](x_{1} , y_{1} ) and (x_{2} , y_{2} )[/tex] in the 7-point slope form. Let's choose (1, 3) and (2, 5).

The slope m can be calculated as:

[tex]m = (y_{2} - y_{1} ) / (x_{2} - x_{1} )[/tex]

m = (5 - 3) / (2 - 1)

m = 2

Now we can plug in the values of[tex](x_{1} , y_{1} )[/tex] , m, and x into the 7-point slope form to get the equation of the line:

[tex](y_{2} - y_{1} ) =m (x_{2} - x_{1} )[/tex]

(y - 3) = 2(x - 1)

y - 3 = 2x - 2

y = 2x + 1

So the equation of the line that passes through the 7 points (1, 3), (2, 5), (3, 7), (4, 9), (5, 11), (6, 13), and (7, 15) is y = 2x + 1.

In summary, the 7-point slope form is a variation of the point-slope form that requires knowing the coordinates of 7 points on a line. Once you have these coordinates, you can use the 7-point slope form to find the equation of the line.
