How much should be deposited in an account paying 3% interest, compounded monthly, in order to have a balance of $9,000 after 17 years and 3 months?

Answer:

17*10^-3 miles

Step-by-step explanation:

Given data

Speed= 8.5×10^−6 miles per second

Time taken=2×10^3 seconds

We know that the expression for the speed is given as

speed= distance/time

distance= speed* time

substitute

distance= 8.5×10^−6* 2×10^3

distance= 8.5*2*(10^-6+3)

distance= 17*10^-3 miles

Answer:

The answer given is incorrect

The correct answer is Rs. 3640

The total cost of the paper required to cover one-half of the wooden cone is Rs. 3846.5.

The surface area of a cone is given by the formula:

surface area = π x r x s

where r is the radius of the base of the cone and s is the slant height of the cone. The slant height of the cone is the distance from the apex of the cone to the base, measured along the surface of the cone.

In this case, the diameter of the base of the cone is 14 cm, so the radius is half the diameter or 14 cm / 2 = 7 cm.

The vertical length of the cone is 24 cm, so the slant height of the cone is the square root of the vertical length squared plus the radius squared:

s = √(24² + 7²)

s = √(576 + 49)

s = √(625)

Which simplifies to:

s = 25 cm

Now that we have the radius and slant height of the cone, we can use the formula for the surface area of a cone to find the surface area of one-half of the cone:

surface area = π x 7 cm x 25 cm = 175π cm²

To find the total cost of the paper required, we need to multiply the surface area by the cost per square centimeter:

total cost = 175 x 3.14 cm² x  Rs.7/cm² = Rs. 3846.5

Therefore, the cost of the paper needed to cover one-half of the wooden cone is Rs. 3846.5.

Answer:

8

Step-by-step explanation:

The degree of a polynomial refers to the term with the highest exponent.  Thus the highest exponent in a degree 3 polynomial is x3; for a degree 5 polynomial, it's x5.  When you multiply

x3*x5 = x3+5 = x8.  

So the product of a degree 3 polynomial and a degree 5 polynomial is a degree 8 polynomial.

Your leading term will result from the 3-degree term of the first polynomial, and the 5-degree term of the second.  So you'll have something like ax3 * bx5.  That will result in x3*x5=x8, so your product will have degree 8.

After considering the given data we conclude that the matrix representation of the derivative map [tex]P_3(R) - - - > P_3(R)[/tex]with respect to the basis[tex](1, x, x^2, x)[/tex]is:
[0 1 0 0]
[0 0 2 0]
[0 0 0 3]
[0 0 0 0]
And the image of the polynomial is [tex]3 + 3x + 10x^2.[/tex]

The first part of the question asks for the matrix representation of the derivative map [tex]P_3(R) - - - > P_3(R)[/tex]with respect to the basis [tex](1, x, x^2, x)[/tex] To find this matrix, we have to apply the derivative map to each basis vector and express the result as a linear combination of the basis vectors. The coefficients of these linear combinations will form the columns of the matrix representation.
Applying the derivative map to each basis vector, we get:
[tex]d/dx(1) = 0 = 0(1) + 0(x) + 0(x^2) + 0(x^3)[/tex]
[tex]d/dx(x) = 1 = 0(1) + 1(x) + 0(x^2) + 0(x^3)[/tex]
[tex]d/dx(x^2) = 2x = 0(1) + 0(x) + 2(x^2) + 0(x^3)[/tex]
[tex]d/dx(x^3) = 3x^2 = 0(1) + 0(x) + 0(x^2) + 3(x^3)[/tex]
Therefore, the matrix representation of the derivative map [tex]P_3(R) - - - > P_3(R)[/tex]with respect to the basis [tex](1, x, x^2, x)[/tex] is:
[0 1 0 0]

The second part of the question concerns  for the image of the polynomial 2x - 1 under the linear transformation h with matrix representation:
[0 2]
[2 1]
[4 2]
with respect to the bases B = {1+2, x} and D = {(1), (-1)}.
To evaluate the image of 2x - 1, we first need to express it as a linear combination of the basis vectors in B:
[tex]2x - 1 = (-1/2)(1+2) + (2)(x)[/tex]
Next, we need to evaluate the coordinate vector of this linear combination with respect to the basis B. The coordinate vector is:
[-1/2]
Now, we can evaluate the image of 2x - 1 under h by multiplying the matrix representation of h by the coordinate vector:
[0 2]

[4 2]
[-1/2]

Answer:

<WZY = 31°

Step-by-step explanation:

First, we can see that <XZW is equal to <WZY.

Given that, we know we can set the two equations equal to each other to find "x".

8x - 1 = 5x + 11

Now that the two equations are set equal to each other, all we have to do is simplify to find x.

Bring 5x over and subtract it from 8x.

3x - 1 = 11

Bring -1 over and add it to 11.

Since you're subtracting a negative, it becomes positive allowing you to add it to 11.

3x = 12

Now you need to get x by itself. Do do that, you need to divide three by itself, and whatever you do to one side, you must do to the other.

3x/3 = 12/3

Now you have:

x = 4

____________________________________________________

Now that you know the value of x, all you need to do is plug x back into the equation for <WZY

5(4) + 11

20 + 11

31.

And there is your answer - <WZY = 31°

Which list has a mean of 21 and median of 20

Each of the list have 5 numbers and they've all been sorted.

The median is the number at the 3rd position (i.e. the middle number)

So, list C and D are out because they do not have a median of 20.

Next, calculate the mean of lists A and B

[tex]\bar x = \frac{\sum x}{n}[/tex]

A. 18, 20, 20, 22, 25

[tex]\bar x = \frac{18 + 20 + 20 + 22 + 25}{5}[/tex]

[tex]\bar x = \frac{105}{5}[/tex]

[tex]\bar x = 21[/tex]

 [tex]\bar x = \frac{20 + 20 + 20 + 25 + 25}{5}[/tex]

[tex]\bar x = \frac{110}{5}[/tex]

The total number of choices for selecting 6 representatives without any two occupying neighboring seats is 77597520 .

(a) The number of ways to arrange 5 parents, 5 students, and 1 teacher in a circular arrangement around a table such that no student sits next to another student and no parent sits next to another parent, we can use the principle of inclusion-exclusion.

First, let's consider the arrangements without any restrictions. We have a total of 11 people to arrange around the table (5 parents + 5 students + 1 teacher), which can be done in (11 - 1)! = 10! ways.

Now, let's consider the arrangements where at least two students sit next to each other. We can treat the two adjacent students as a single entity, resulting in 10 entities to arrange around the table (4 parents + 5 student pairs + 1 teacher). This can be done in (10 - 1)! = 9! ways. However, within each student pair, the students can be arranged in 2! ways. Therefore, the total number of arrangements with at least two students sitting next to each other is 9! × 2! ways.

Similarly, we consider the arrangements where at least two parents sit next to each other. Again, we treat the two adjacent parents as a single entity, resulting in 10 entities to arrange around the table (4 parent pairs + 5 students + 1 teacher). This can be done in (10 - 1)! = 9! ways. Within each parent pair, the parents can be arranged in 2! ways. Therefore, the total number of arrangements with at least two parents sitting next to each other is 9! × 2! ways.

By the principle of inclusion-exclusion, the number of valid arrangements is given by

Valid arrangements = Total arrangements - Arrangements with at least two students sitting next to each other - Arrangements with at least two parents sitting next to each other

Valid arrangements = 10! - 9! × 2! - 9! × 2!

Valid arrangements = 2177280

(b) The number of choices for selecting 6 representatives out of 20, where no two chosen representatives occupy neighboring seats, we need to use a combination of counting techniques.

First, choose 6 seats out of the 20 seats in which the representatives will be seated. This can be done in C(20, 6) ways.

Now, since no two chosen representatives can occupy neighboring seats, we can think of the remaining 14 seats as dividers between the chosen representatives. We need to place these dividers in such a way that each chosen representative occupies a separate section.

To ensure that no two representatives occupy neighboring seats, we need to place the dividers such that each section contains at least one seat. We have 6 chosen representatives, so we need to place 5 dividers among the 14 remaining seats. This can be done in C(14, 5) ways.

Therefore, the total number of choices for selecting 6 representatives without any two occupying neighboring seats is given by:

Total choices = C(20, 6) × C(14, 5)

Total choices =  38760 × 2002

Total choices = 77597520

In the Italian class survey, 50 students were asked about how they listen to music. A Venn diagram was used to represent the information. Five students liked none of the types of music, 37 students liked exactly two types of music, and 39 students liked at least two types of music.

(a) The information can be represented in a Venn diagram as follows:

In the diagram, S represents the number of students who listen to Spotify, P represents the number of students who listen to Pandora, and R represents the number of students who listen to the radio. The overlapping regions show the number of students who listen to multiple platforms.

         ___________

        |           |

        |    S      |

        |___________|

        |           |

   R    |    SP     |   P

        |___________|

        |           |

        |     RP    |

        |___________|

(b) To determine the number of students who liked none of these types of music, we need to find the students who did not fall into any of the three categories. This can be calculated by subtracting the total number of students who liked at least one type of music from the total number of students surveyed.

Total number of students surveyed = 50

Students who liked at least one type of music = S + P + R - (SP + SR + PR) + SPR

Substituting the given values:

Students who liked at least one type of music = 34 + 30 + 18 - (22 + 13 + 4) + 2 = 45

Students who liked none of these types of music = Total number of students surveyed - Students who liked at least one type of music

Students who liked none of these types of music = 50 - 45 = 5

Therefore, 5 students liked none of these types of music.

(c) To find the number of students who liked exactly two types of music, we need to calculate the sum of the students in the overlapping regions of the Venn diagram.

Students who liked exactly two types of music = SP + SR + PR - (SPR)

Substituting the given values:

Students who liked exactly two types of music = 22 + 13 + 4 - 2 = 37

Therefore, 37 students liked exactly two types of music.

(d) To determine the number of students who liked at least two types of music, we need to add the students who liked exactly two types of music to the number of students who liked all three types of music.

Students who liked at least two types of music = Students who liked exactly two types of music + Students who liked all three types of music

Students who liked at least two types of music = 37 + 2 = 39

Therefore, 39 students liked at least two types of music.
