Find the first, fourth, and eighth terms of the sequence. A(n) = –2 • 2^n–1


A. –4; –32; –512

B. 1; –64; –16,384

C. –8; –64; –1,024

D. –2; –16; –256

Answers

Answer 1

Answer:

D

Step-by-step explanation:

given that

A(n)=-2•2^(n-1)

n->represent the terms

A(1)=-2•2^(1-1)=>-2•2^0

A(1)=-2•1=-2

For the fourth term

A(4)=-2•2^(4-1)

A(4)=-2•2^(3)

A(4)=-16

for the 8th term

A(8)=-2•2^(8-1)

A(8)=-2•2^(7)

A(8)=-256

Therefore first, fourth and eight => -2;-16;-256

-4+4(-8+2n) = -37+8n

Answers

Answer:

No solutions for n

Step-by-step explanation:

Distribute the 4 to the -8 and the 2n

-4 + 4*-8 + 4*2n = -37 + 8n

Multiply

-4 - 32 + 8n = -37 + 8n

Subtract 8n on both sides

-4 - 32 = -37

Subtract on the left

-36 = -37

No solutions because -36 does not equal -37

Answer:

No solution

Step-by-step explanation:

-4 + 4(-8 + 2n) = -37 + 8n

-4 - 32 + 8n = -37 + 8n

-36 + 8n = -37 + 8n

8n - 8n = -37 + 36

0 = -1

Since 0 does not equal 1, this is a “No Solution”

The answer Is A 1 1/5 < -2 2/5

Step-by-step explanation:

It says that this statement is true because 1 1/5 is to the left of -2 2/5 on the number line but it is actually to the right because -2 2/5 is negative while 1 1/5 is positive therefore making it larger and the correct statement would be that    1 1/5 > -2 2/5

Find the 11th term of the geometric sequence 10,20,40

answer = 10,240

Answer:

10,240

Step-by-step explanation:

First, we find the constant ratio by dividing a number by the previous number.

r = 40/20 = 2

Now we apply the formula for term a_n of a geometric sequence.

a_n = a_1 * r^(n - 1)

a_11 = 10 * 2^(11 - 1)

a_11 = 10 * 2^10

a_11 = 10,240

Answers

Answer:

X equals 8.

Step-by-step explanation:

The polygon in the question has 5 sides. However, it is an irregular polygon hence the sides are given as 62 degrees, 66 degrees, 77 degrees, 59 degrees and 12X degrees.

The size of the exterior angle of a polygon is calculated as

Angle = 360/n

Where n is the number of sides. So for a five sided polygon, the size of the exterior angle is calculated as

360/5 which equals 72. Since it is an irregular polygon, the sum of the exterior angles can be expressed as

62 + 66 + 77 + 59 + 12X = 360

264 + 12X = 360

Subtract 264 from both sides of the equation

12X = 96

Divide both sides of the equation by 12

X = 8

The value of x in the given polygon is 8.

What is Polygon?

A polygon is a plane figure made up of line segments connected to form a closed polygonal chain

The polygon in  has 5 sides.

It is an irregular polygon hence the sides are given as 62 degrees, 66 degrees, 77 degrees, 59 degrees and 12X degrees.

The size of the exterior angle of a polygon is calculated as

Angle = 360/n

Where n is the number of sides.

So for a five sided polygon, the size of the exterior angle is calculated as

360/5 =72.

Since it is an irregular polygon, the sum of the exterior angles can be expressed as

62 + 66 + 77 + 59 + 12X = 360

264 + 12X = 360

12X = 96

Divide both sides of the equation by 12

X = 8

Hence, the value of x in the given polygon is 8.

I am the only toolkit function that has a start and end number for the range. I am also the only that is cyclic, meaning I repeat over and over.


Which toolkit function am I?

Answers

The Toolkit function that has a start and end number for the range and is also cyclic is ; The constant Function ( i.e. f(x) = a )

There are about (9) toolkit functions and some of these toolkit functions :

Constant function Cube root function Square root functionreciprocal squared functionreciprocal functioncubic and quadratic function Absolute value function

The common characteristics between the various toolkit functions is that they all have undefined domains ( i.e. ( - ∞ , ∞ ) or ( -∞, 0 ), and undefined ranges as well.  while the only Toolkit function with a defined range is the Constant function { a, a }

The range for a Constant function starts and ends with the value of the given constant. i.e. { a, a }. while other functions have undefined range values.

Hence we can conclude that the Toolkit function with a start and end number for the range is the Constant function.
