given the sequence tn defined recursively below, find t4.

Given The Sequence Tn Defined Recursively Below, Find T4.

Answers

Answer 1

Answer:

[tex]t_4 = 20[/tex]

Step-by-step explanation:

The base case in the recursive function are:

[tex]t_1 = 1[/tex]

[tex]t_2 = 2[/tex]

The recursive case is equal to:

[tex]t_n = 2t_{n-1} + 3t_{n-2}[/tex]

So replace [tex]t_n[/tex] for [tex]t_4[/tex]:

[tex]t_4 = 2t_{3} + 3t_{2}[/tex]

In the new expression [tex]t_2[/tex] is a base case so you don't have to worry for that part, but [tex]t_3[/tex] is still the recursive case so evaluate again in [tex]t_n[/tex]

[tex]t_3 = 2t_{2} + 3t_{1}[/tex]

[tex]t_2[/tex] and [tex]t_1\\[/tex] are define as base cases so you replace for it's numbers:

[tex]t_3 = 2(2) + 3(1) = 7[/tex]

Now return to [tex]t_4[/tex] and replace for the new values:

[tex]t_4 = 2(7) + 3(2) = 14 + 6 = 20[/tex]

So the final answer is 20

Aubrey wrote a business plan for an entrepreneurship class, and now she has to make bound copies. Aubrey could use a printer who charges a setup fee of $38 and $3 for every copy printed. Another possibility is to go to the office supply store, where she could pay an up-front fee of $34 and $4 per copy. There is a certain number of copies that makes the two options equivalent in terms of cost. How much would the copies cost? How many copies is that?

Answers

Answer:

Copies cost for the first case = $ 12

Copies cost for the second case =$16

Number of Copies = 4

Step-by-step explanation:

Let the number of copies = N

. for the first case: total cost (T1) = 38 + 3N

. for the second case: total cost (T2) = 34 + 4N

Determine the ‘N’ when the cost is equivalent

So, 38 + 3N = 34 + 4N

38 – 34 = 4N – 3N

N = 4

Therefore, number of copies = 4

Copies cost for the first case = 3 × 4 = $12

Copies cost for the second case = 4 × 4 = $16

#1.

Set up fee=$38Cost per copy=$3

Expression

[tex]\sf\longmapsto 38+3x[/tex]

#2

Set up fee=$34Cost per copy=$4

Expression

[tex]\sf\longmapsto 34+4x[/tex]

Now

Answers

Answer: 13 3/4

Step-by-step explanation:

The gopher’s new elevation relative to the surface of the ground will be

[tex]13 \frac{1}{4}[/tex] inches.

What is Addition?

A process of combining two or more numbers is called addition.

Given that;

A gopher is in a hole that is [tex]6 \frac{1}{4}[/tex] in. below the surface of the ground.

And, Then digs [tex]7 \frac{1}{2}[/tex]  in. deeper.

Now,

The gopher’s new elevation relative to the surface of the ground will be calculated as;

⇒ [tex]6 \frac{1}{4} + 7 \frac{1}{2}[/tex]

⇒ 25/4 + 15/2

Make denominators same as;

⇒ 25/4 + 30/4

⇒ (25 + 30) / 4

⇒ 55 / 4

⇒ [tex]13 \frac{1}{4}[/tex] inches.

Thus, The gopher’s new elevation relative to the surface of the ground will be [tex]13 \frac{1}{4}[/tex] inches.

Answers

Answer:

c=2

Step-by-step explanation:

translation:

5x2-3x2=c2

10-6=4

4=c2

4/2=c2/2=c=2

When a = 5 and b = 3, the value of c is 4, based on the equation [tex]a^2 - b^2 = c^2[/tex].

Given the equation [tex]a^2 - b^2 = c^2[/tex] and the values a = 5 and b = 3, we can substitute these values into the equation and solve for c.

Substituting a = 5 and b = 3:

[tex](5)^2 - (3)^2 = c^2\\\\25 - 9 = c^2\\\\16 = c^2[/tex]

Taking the square root of both sides:

c = √16

c = 4

Therefore, when a = 5 and b = 3, the value of c is 4.

Amazon Inc. has been sued for following three alleged infringements of law: (1) Unauthorized use of a trademark; the claim is for $100 million (2) Nonpayment of end-of-service severance pay and gratuity to 5,000 employees who were terminated without Amazon Inc. giving any reason; the class action lawsuit is claiming $3 million (3) Unlawful environmental damage for dumping waste in the river near its factory; environmentalists are claiming unspecified damages as cleanup costs (4) Legal counsel is of the opinion that not all the legal cases are tenable in law and has communicated to Amazon Inc. this assessment of the three lawsuits: (5) Lawsuit 1: The chances of this lawsuit are remote. (6) Lawsuit 2: It is probable that Amazon Inc. would have to pay the displaced employees, but the best estimate of the amount that would be payable if the plaintiff succeeds against the entity is $2 million. (7) Lawsuit 3: There is no current law that would compel the entity to pay for such damages. There may be a case for constructive obligation, but the amount of damages cannot be estimated with any reliability. Required: What should be the provision that Amazon Inc. should recognize or the contingent liability that it should disclose in each of the lawsuits, based on the assessments of its legal counsel?

Answers

The International Financial Reporting Standards developed standards can

be implemented to ascertain the provisions and disclosures to be made.

The correct responses are;

According to the financial reporting standard, the contingent liability that

Amazon Inc. should disclose and the provision that Amazon Inc. should

recognize, based on the legal consent are;

Lawsuit 1: It is not required to make provision or disclosure because the

probability of the lawsuit progressing is remote and therefore, the

Company will not be required to payout money or lose economic benefits.

Lawsuit 2: The likelihood of the Company having pay the displaced

employees is high however, the amount payable is $2 million, and

therefore, a provision of $2 million is required in the financial reporting.

Lawsuit 3: The Company is not legally obliged to pay for or perform the

cleanup, but based on the relationship between the Company's waste

location, the river, and the community, there is a constructive obligation,

the amount of which cannot be determined with reliability.

Therefore, there is a requirement for disclosure as a contingent liability,

and not a provision as the claim cannot be classified as a provision.

What is the chain rule in probability?

For two events A and B, by chain rule, we have:

[tex]P(A \cap B) = P(B)P(A|B) = P(A)P(B|A)[/tex]

where P(A|B) is the probability of occurrence of A given that B already occurred.

A weather forecaster has a 60% chance of predicting the weather correctly today.

If she is correct, then the probability of being correct the next day is 80%.

If she is wrong, the chance of predicting incorrectly the next day is increased by 25% that she was wrong the previous day.

Let the chance of predicting the weather correctly today be A.

Let the chance of predicting the weather correctly the next day be B.

Then the probability that the forecaster will predict the weather correctly in exactly two of the next three days will be

[tex]P(A \cap B) = P(A)P(B|A) = 0.6 \times 0.8 = 0.48[/tex]
