What kind of sequence is this?
5, 8, 13, 21,
arithmetic
geometric
both
neither

Answers

Answer 1

The sequence 5, 8, 13, 21, is option D: neither an arithmetic nor a geometric sequence.

What is a sequence?

A sequence is an enumerated group of items in mathematics where repetitions are permitted and order is important. Similar to a set, it has members (also called elements, or terms). The length of the series is the number of elements (potentially infinite).

In an arithmetic sequence, each term is obtained by adding a fixed constant to the preceding term.

In a geometric sequence, each term is obtained by multiplying the preceding term by a fixed constant.

For example, an arithmetic sequence with a first term of 2 and a common difference of 3 would be -

2, 5, 8, 11, 14, ...

And a geometric sequence with a first term of 2 and a common ratio of 3 would be -

2, 6, 18, 54, 162, ...

In the given sequence 5, 8, 13, 21, it can be seen that the difference between successive terms is not constant (i.e., 3-5 = -2, 13-8 = 5, 21-13 = 8).

Therefore, this is not an arithmetic sequence.

Similarly, the ratio between successive terms is not constant, so this is not a geometric sequence either.

Therefore, this sequence is an example of a more general type of sequence that does not follow a simple pattern, and is often referred to as a non-linear sequence.

Which equation demonstrates the multiplicative identity property?

Answers

Answer:

B. (-3+5i)(1)= -3+5i

Step-by-step explanation:

The multiplicative identity property states that any number or polynomial times 1 will be equal to itself. In answer B, a polynomial is multiplied by 1 and then equals itself. None of the other answers have 1 as a term, and therefore cannot be correct.

a. Write a formula for the area A
of a triangle.
b. Solve the formula for b.
c. Use the new formula to find the
base of the triangle.
A = 36 mm2
h = 6 mm
b

Answers

Answer:

A = 1/2 b * h

b = 2A / h

b = 12

Step-by-step explanation:

Remark

The formula starts out as

A = 1/2 * b * h  

You want to rearrange it to show b by itself.

Formula

Multiply by 2

2A = b * h            

Divide by h

2A/h = b

Part C

b = 2A / h

A = 36 mm^2

h = 6 mm

b = 2*36 / 6

b = 72 / 6

b = 12 mm

Step-by-step explanation:

1) Find the volume of the cube

[tex]A=l^3[/tex] where l is the side length

Plug in 9 ft as l

[tex]A=9^3\\A=729[/tex]

Therefore, the volume of the cube is 729 ft³.

2) Find the volume of the cylinder

[tex]A=\pi r^2h[/tex] where r is the radius of the base and h is the height of the cylinder

Plug in 3 ft as the radius and 9 as the height

[tex]A=\pi (3)^2(9)\\A=\pi (9)(9)\\A=81\pi \\A=254.5[/tex]

Therefore, the volume of the cylinder is approximately 254.5 ft ³.

3) Subtract the volume of the cylinder from the volume of the cube

729 ft³ - 254.5 ft ³

= 474.5 ft ³

Therefore, the volume of the figure is 474.5 ft ³.

A spinner used in a board game is divided into 8 equally sized sectors. Three of these sectors indicate that the player should move his token forward on the board, two of these sectors indicate that the player should move his token backward, and the remaining sectors award the player bonus points but do not move his token on the board. The total area of the sectors that do not allow the player to move his token is 35.9 inches squared. What is the radius of the spinner

Answers

Answer:

5.52 inch

Step-by-step explanation:

Recall :

Area of Sector : θ/ 360 * πr²

Sectors that do not allow movement : (8-3-2) = 3

Total sectors = 8

θ/ 360 = 3/8 ; Area = 35.9

Radius = r

35.9 = 3/8 * π * r²

35.9 / (3/8 * π) = r²

30.472866 = r²

r = √30.472866

r = 5.52 inch

The radius of the spinner is 5.520 inch whose  [tex]\frac{3}{8}[/tex]  sector area is 35.9 inches square.

It is given that the spinner used in a board game is divided into 8 equally sized sectors. three sectors indicate that the player should move his token forward on the board, two sectors indicate that the player should move his token backward, and the remaining sectors award the player bonus points but do not move his token on the board and its area of the sector is 35.9 inches square.

It is required to find the radius of the spinner.

What is the area of the sector?

The region enclosed by the two radii of a circle and the arc is known as a sector's area. In other words sector area is a portion of the circle's area.

We know the formula of sector area (A):

[tex]\rm A= \frac{\theta}{360 \°} \pi r^2[/tex]    Where 'r' is the radius of the circle and [tex]\rm \theta[/tex] is in degree

The remaining sectors = ( Total sectors - Three sectors - Two sectors)

= ( 8 - 3 - 2) ⇒ 3 sectors indicate the player do not move his token

Total sector = 8

[tex]\rm \frac{\theta }{360 \° } = \frac{3}{8} \ when \ A = 35.9 \ inches^2[/tex]

Putting these values in the above formula, we get:

[tex]\rm 35.9 = \frac{3}{8} \pi r^2\\\rm 35.9\times 8 = 3\pi r^2\\\rm 287.2 = 3\pi r^2\\\\\rm \frac{287.2}{3} = \pi r^2\\\\\rm 95.733= \pi r^2\\\rm 30.4728 = r^2[/tex]Where [tex]\rm \pi[/tex] = 3.14159

[tex]\sqrt{30.4728} = r\\\rm 5.520= r \\\rm or = 5.520 \ inch[/tex]

Thus, the radius of the spinner is 5.520 inch.
