The formula for any geometric sequence is an = a1 · rn - 1 , where an represents the value of the n th term, a1 represents the value of the first term, r represents the common ratio, and n represents the term number. What is the formula for the geometric sequence 4, 8, 16, 32, ...? an = 4 · ( ) n - 1 an = 2 · 4 n - 1 an = 32 · 2 n - 1 an = 4 · 2 n - 1

Answers

Answer 1

Answer:

an = 4 · 2^(n - 1)

Step-by-step explanation:

Given:

an = a1 · r^(n - 1)

Where,

an = value of the n th term

a1 = value of the first term

r = common ratio

n = the term number.

What is the formula for the geometric sequence 4, 8, 16, 32, ...?

a1 = 4

r = 8/4

= 2

n = n(not given)

Substitute the values of a1 and r into the formula

a1 = 4

r = 2

an = a1 · r^(n - 1)

an = 4 * 2^(n - 1)

The correct answer is:

an = 4 · 2^(n - 1)

Answer 2

Answer:

an = 4 · 2^(n - 1)

SOMEONE PLEASE HELP!!!Which of the following represents the synthetic division form of the long
division problem below?

Answers

Answer:

Choice C

Step-by-step explanation:

When setting up synthetic division you do:

x-5=0

x=5

and get the numerator's coefficients:

1, -3, 4

                   

so that's 5 | 1 -3 4

Answer:

C

Step-by-step explanation:

You need to equal the denominator (x — 5 = 0)

When you leave the x alone the result is x=5, so the number outside the “house” is five.

Then you look at the equation in the numerator and you place the coefficients in order and with their signals.

X^2 the coefficient is 1

-3x the coefficient is -3

4 the coefficient is 4

Answers

a) the modal class interval is 0 - 2

b) the mean number of letters delivered = 3.2

In this question, we have been given the table that shows some information about the number of letters delivered to 50 houses.

a) To find the modal class interval

In given table, the maximum frequency is 25 and the corresponding class-interval is 0 - 2.

so, the modal class interval is 0 - 2

b) To find an estimate for the mean number of letters delivered.

Number of letters | mid-point | Number of |  (mid-point × frequency)

    delivered          |                  |     houses   |

      0 - 2                |       1          |        25        |               25

      3 - 4                |      3.5       |         12        |               42

Corrine bought 8.4 pounds of almonds. She divided them into 30 snack-size bags. How many pounds are in each bag?
helphelphelp ASAPPPPP!!!!!

Answers

Answer:

0.28 pounds in each bag.

Step-by-step explanation:

There are 0.28 pounds in each snack-size bag.

What is the division operation?

In mathematics, divides left-hand operands into right-hand operands in the division operation. The primary purpose of the division is to generate equal groupings.

For example 4/2 = 2

We have been given that she bought 8.4 pounds of almonds. She divided them into 30 snack-size bags.

We have to determine the number of pounds in each bag.

The number of pounds in each bag = total quantity of almonds ÷ number of bags

The number of pounds in each bag = 8.4 pounds ÷ 30 bags

The number of pounds in each bag = 8.4/30

Apply the division operation, and we get

The number of pounds in each bag = 0.28 pounds

Thus, there are 0.28 pounds in each snack-size bag.

2−(x−10)=5x
what is x?

Answers

Answer:

2

Step-by-step explanation:

2−(x−10)=5x

Step 1: Simplify both sides of the equation.

2−(x−10)=5x

2+−1(x−10)=5x(Distribute the Negative Sign)

2+−1x+(−1)(−10)=5x

2+−x+10=5x

(−x)+(2+10)=5x(Combine Like Terms)

−x+12=5x

−x+12=5x

Step 2: Subtract 5x from both sides.

−x+12−5x=5x−5x

−6x+12=0

Step 3: Subtract 12 from both sides.

−6x+12−12=0−12

−6x=−12

Step 4: Divide both sides by -6.

−6x−6=−12−6

x=2

Answer:

x=2

Answer:

x = 2

Step-by-step explanation:

2-(x-10) = 5x

distribute the - into the  (  )

2 -x + 10 = 5x

combine like terms

12 - x = 5x

     +x    +x

12 = 6x

divide both sides by 6

x = 2

Given a circle with the center (4,0) with a point P(4,8) on the circle, find the diameter of the circle.

Answers

Answer:

16

Step-by-step explanation:

To find the radius find the distance between (4,0) and (4,8). The radius is 8. Then multiply by 2 to find out the diameter.

Answer:

16

Step-by-step explanation:

Graphing the two points, you see that (4,8) is 8 points away from (4,0) - the center of the circle.

Knowing that 8 would be the radius, and that diameter = 2(radius), multiply the radius by two to find the diameter.

diameter = 2(8)

diameter = 16

What is sample space?

"A sample space is a collection or a set of possible outcomes of a random experiment. The sample space is represented using the symbol, “S”. The subset of possible outcomes of an experiment is called events. A sample space may contain a number of outcomes that depends on the experiment. If it contains a finite number of outcomes, then it is known as discrete or finite sample spaces."

"The samples spaces for a random experiment is written within curly braces “ { } “. There is a difference between the sample space and the events."
