12.3 geometric series evaluate homework and practice

Answers

Answer 1

The geometric series would have a uniform common ratio

The recursive definition of the geometric sequence is [tex]a_n = 4a_{n-1}[/tex] where a1 = 128

How to determine the geometric series?

Assume the geometric sequence is given as:

128,32,8,2

And the question requires the recursive definition of the geometric series

Start by calculating the common ratio (r)

[tex]r = \frac{a_{n}}{a_{n-1}}[/tex]

Substitute 2 for n

[tex]r = \frac{a_2}{a_1}[/tex]

Substitute known values

[tex]r = \frac{128}{32}[/tex]

Evaluate the quotient

[tex]r = 4[/tex]

Substitute 4 for r in [tex]r = \frac{a_{n}}{a_{n-1}}[/tex]

[tex]4 = \frac{a_{n}}{a_{n-1}}[/tex]

Cross multiply

[tex]a_n = 4a_{n-1}[/tex]

Hence, the recursive definition of the geometric series is [tex]a_n = 4a_{n-1}[/tex] where a1 = 128

A network administrator is measuring the transfer of bits across the company backbone for a mission critical financial application. the administrator notices that the network throughput appears lower than the bandwidth expected. which three factors could influence the differences in throughput? (choose three.)

Answers

The three factors that could influence differences in lower levels of network throughput compared to the bandwidth expected are:

The current volume of traffic crossing the networkThe kind of traffic that passes through the networkThe delay (latency) that is created by the number of network device(s) connections that the data is crossing.

What are throughput and bandwidth in networking?

Throughput indicates the amount of data sent from a source at any particular time, whereas bandwidth indicates the amount of data that might potentially be transmitted from a station at any given moment.

You have crucial data for measuring network performance provided you know the network's throughput and bandwidth levels. Operators who want a comprehensive view of their network's performance need to understand how throughput, as well as, bandwidth is operating.

Scalable, flexible, and adaptable operational capabilities are indeed included in the (NRF)National Response Framework's five key principles.

The National Response Framework (NRF) is a comprehensive guide developed by the United States Department of Homeland Security to facilitate effective response and recovery efforts during emergencies, disasters, and incidents. The NRF's five key principles, known as the "Five Mission Areas," outline the fundamental aspects of emergency management. These mission areas include:

1. Prevention: Activities aimed at preventing emergencies or disasters from occurring. This involves measures such as risk assessment, hazard mitigation, and public education to minimize the likelihood of incidents.

2. Protection: Actions focused on safeguarding individuals, critical infrastructure, and key assets from potential threats and hazards.

3. Mitigation: Efforts to reduce the impact and severity of disasters by implementing measures to minimize the potential damage and disruption caused by hazards.

4. Response: Immediate actions are taken to address and manage the consequences of an incident. This includes coordinating emergency response activities, mobilizing resources, conducting search and rescue operations, providing medical assistance, and ensuring public safety.

5. Recovery: Activities aimed at restoring affected communities and rebuilding the impacted areas after an incident. This includes facilitating the recovery process, providing assistance to individuals and businesses, restoring critical services, and rebuilding infrastructure.

In summary, scalable, flexible, and adaptable operational capabilities are integral to the National Response Framework's five key principles, as they enable effective emergency management and response during various incidents and disasters.

At its current level of output, a firm’s total revenue is greater than its total variable cost but less than its total cost. if the firm is producing at the point where marginal revenue is equal to marginal cost, what should the firm do to maximize profit in the short run?

Answers

In order to maximize profit in the short run; Company is to continue operating at that output level in the short term, since total revenue will cover all of the firm's variable costs and some of its fixed costs.

How to maximize profit?

Every firm in the market operates with the primary aim of making profit, which is different from the government that has a primary aim of creating welfare for the people. Thus, a profit-maximizing level of output is determined at the point where marginal revenue (MR) equals marginal cost (MC).

Finally, In order to maximize profit in the short run what the company should do is to continue operating at that output level in the short term, since total revenue will cover all of the firm's variable costs and some of its fixed costs.
