Determine whether the sequence converges or diverges. If it converges, give the limit.

9, 27, 81, 243,

Answers

The sequence diverges because the value of the absolute common ratio r is greater than the 1.

What is convergent of a series?

A series is convergent if the series of its partial sums approaches a limit; that really is, when the values are added one after the other in the order defined by the numbers, the partial sums getting closer and closer to a certain number.

We have series:

9, 27, 81, 243....

The above series is a geometric progression with common ratio r is 3

[tex]\rm r =\dfrac{27}{9}[/tex]

r = 3

We know the formula for a geometric sequence:

[tex]\rm S_n = 9(3)^n[/tex]

[tex]\rm S_n = 3^{n+2}[/tex]

A geometric series converges only if the absolute value of the common ratio:

r < 1 and

It diverges if the ratio ≥ 1

Here the value of r = 3 which is greater than the 1 so the sequence diverges.

Thus, the sequence diverges because the value of the absolute common ratio r is greater than the 1.

URGETN DUE IN 20 MINUTES PLEASE HELP. Tammy went to Outback for dinner, and took Sue with her. The total bill cost $68.72. Service
was good so they left a 22% tip. If they split the bill, what did each of them pay for dinner.

Answers

Answer:

Step-by-step explanation:

find the tip

68.72 * 0.22 (22%) = 15.1184

I was hoping that 68.72 + 15.1184 would equal a nice round number, like if it had been 80 total, then they both could have dropped 40 dollars. which would make sense, and is probably what would really happen. But this is math, :D and it really doesn't have to make sense, it just has to be accurate.

so 68.72+15.12 = 83.84

83.84 / 2 =41.92 they each paid 41.92 or for crying out loud, would they really dig around for 92 cents? just give the waiter one whole dollar. So for accuracy they would each pay $41.92, but really they would each pay 42.00 dollars.. and to even be more real. they would each pay $40.00

A 5.0 µC point charge is moved within an electric field and has an electric potential energy change of 10.0 J. What is the electric potential difference before and after the charge was moved? Show work. (µC = 1.0 × 10–6)

Answers

For a 5.0 µC point charge moved within an electric field, the electric potential difference is mathematically given as

du=2*10^6

What is the electric potential difference before and after the charge was moved?

Generally, the equation for the change in potential energy is mathematically given as

dV=qdu

Therefore

10=5*10^{-6}*du

du=2*10^6

In conclusion, the electric potential difference

du=2*10^6

A coin is Flipped 3 times. What IS the probability that the coin lands heads up once and tails up twice if order does not matter?

Answers

Answer:

The probability that the coin lands heads up once and tails up twice is .375, or 3/8.

Step-by-step explanation:

Check the conditions for a binomial distribution problem:

Define success = heads and failure = tails.The number of trials is fixed; n = 3.Each coin flip is independent of the other.Probability p = .5 of getting either heads or tails.

We need to use combinations to determine the probability of getting one success (one head) and two failures (two tails).

The combination would be 3 choose 1: [tex]p = {3 \choose 1} (.5)^1(.5)^2[/tex].

There is one success and two failures, denoted by the superscripts above the probability p = .5.

Use a calculator to evaluate and we get:

[tex](3)(.25)(.5) = .375[/tex]

The probability that the coin lands heads up once and tails up twice is .375, or 3/8.

Answers

Answer:

Introduction:

Binary numbers are used by different departmental stores to keep track of their inventory.

Explanation:

For this the minimum binary numbers should be 8 bits which can represent 256 unique values.

If a store needs to represent its inventory items between 25 to 75, it should use at least 8 bits which can formulate a eight bit number for every item.
