1. Find the general formula that gives the nth term for each of the sequences below
(remember this is NOT the recursive rule).
(a) Odd numbers:
(b) Triangular numbers:
(c) Square numbers:

Answers

9514 1404 393

Answer:

  (a)  an = 2n -1

  (b)  an = n(n +1)/2

  (c)  an = n^2

Step-by-step explanation:

(a) The odd numbers are an arithmetic sequence with first term 1 and common difference 2. The general term is ...

  an = a1 +d(n -1)

  an = 1 + 2(n -1)

  an = 2n -1

__

(b) The triangular numbers are a quadratic sequence with first term 1, first first difference 2, and second differences 1.

The first few terms and differences are ...

  sequence: 1, 3, 6, 10, 15, 21, 28, ... (a1 = 1)

  first diff: . . . 2, 3, 4, 5, 6, 7, ... (d1 = 2)

  2nd diff: . . . . 1, 1, 1, 1, 1, ... (d2 = 1)

There is a sort of general formula* that can make use of these numbers to give the general term of the sequence:

  an = a1 +(n -1)(d1 +(n -2)/2(d2))

For the values we have, this gives our general term as ...

  an = 1 + (n -1)(2 +(n -2)/2(1))

  an = n(n +1)/2

__

(c) The general term in the sequence of square numbers is simply the square of the term number:

  an = n²

_____

* There are a number of other ways to get to the general formula for triangle numbers. You can search for it, since it is well-known. You can use a quadratic regression tool on the sequence of numbers. You can develop a system of equations to find the coefficients of the quadratic equation.

The general formula given can be used to find polynomial sequences of any degree. Coefficients at successive layers in the formula are of the form (n -k)/k. The first term in parentheses following that is the first k-th difference.

Mr. Richardson would like to build a planter surrounded by a brick path (show in gray). How many square feet of brick does Mr. Richardson need? 20ft and 8 ft inside the planter 24ft and 12ft of path

Answers

Answer:

128 ft^2 needed

Step-by-step explanation:

Given

See attachment for missing details

Required

Determine the number square feet needed

First, calculate the inner area (A1)

[tex]A_1 = Length * Width[/tex]

[tex]A_1 = 20ft * 8ft[/tex]

[tex]A_1 = 160ft^2[/tex]

Next, calculate the outer area (A2)

[tex]A_2 = Length * Width[/tex]

[tex]A_2 = 24ft * 12ft[/tex]

[tex]A_2 = 288ft^2[/tex]

The area of the planter is:

[tex]Area = 288ft^2-160ft^2[/tex]

[tex]Area = 128ft^2[/tex]

Hence, he needs 128 square feet

16 mm

What is the length of the hypotenuse?
millimeters

Answers

Answer:

65mm

Step-by-step explanation:

Here, we use the Pythagorean Theorem.

The formula is a^2+b^2=c^2

We plug in the numbers to the formula like this:

16^2+63^2=c^2

256+3969=c^2

4225=c^2

√4225=65

65mm

Hello, I hope you have a good day, can you please help me it would mean a lot........

What is the smaller angle formed by the minute and hour hands at 3:30pm?

Answers

the angle would be a 90° angle

Answer:  75 degrees

========================================================

Explanation:

At 3:00 pm, the hour hand is pointed directly at the '3'. At 4:00 pm, the hour hand moves to point directly at the '4'.

Since 3:30 pm is the halfway point of 3:00 pm and 4:00 pm, this must mean the hour hand is halfway between the '3' and '4'.

Each little tiny tickmark on the clock represents 1 minute. From the "3" to "4", we have 5 tickmarks, so half of that is 5/2 = 2.5

The hour hand is pointing to 2.5 minutes after the 15 minute mark, meaning the hour hand is pointing to the 15+2.5 = 17.5 minute mark.

The span of time from 17.5 minutes to 30 minutes is 30-17.5 = 12.5 minutes.

Divide this over 60 minutes and we get 12.5/60 = 125/600 = 5/24

The 5/24 indicates the fractional amount of 360 degrees being taken up by this angle shown.

So, (5/24)*360 = 75 degrees is the angle measure in this diagram.

Suppose Clara has a collection of old CDs. If the diameter of a CD measures about 12 centimeters, approximate the circumference of the CD. Round your answer to the nearest tenth of a centimeter.

Answers

Answer:

The circumference of the CD is approximately 38 cm

Step-by-step explanation:

The circumference of the CD can be seen as the distance around the CD.

The word "circumference"  is used to describe the perimeter of circular objects.

To find an approximate value of the circumference of the CD, we will use this formula.

Circumference = π × diameter

let us take π to be = 3.142

∴ circumference = 3.142 × 12 = 37.6991 cm

we can round this up to teh nearest tenth as 38cm

Rotate shape A 180 about point (1,0)

Answers

Go to the right and turn

The point after which shape A is rotated 180 degrees is (-1, 0).

What is translation?

It is the movement of the shape in the left, right, up, and down directions.

The translated shape will have the same shape and shape.

There is a positive value when translated to the right and up.

There is a negative value when translated to the left and down.

We have,

Shape A is in the point (1, 0).

This means,

Shape A is in the First Quadrant.

Now,

Shape A is rotated 180 degrees.

If rotated clockwise or counterclockwise shape A will be in the same quadrant.

This means,

Shape A will be in the Third quadrant.

Now,

First quadrant coordinates = (x, y)

Third quadrant coordinates = (-x, -y)

So,

(x, y) → (-x, -y)

(1, 0) → (-1, 0)

Thus,

Shape A will be in (-2, 0).

Fei Yen's dog eats 8 ounces of dog food each day. Fei Yen bought a 32-pound bag of dog food. How many 8-ounce servings are in 32-pound bag of dog food?

Answers

Answer:

64 servings

Step-by-step explanation:

The computation is shown below:

As dog eats 8 ounces of dog food each day

And, he purchased 32 pound bag of dog food

We know that

1 pound = 16 ounces

So for 32 pounds, the ounces would be

= 16 ×32

= 512 ounces

So, the number of 8 ounces servings would be

= 512 ÷ 8

= 64 servings
