Answer:

Three levels of information systems at university include:

1. The students ICT unit (workgroup)

2. The departmental ICT units (enterprise)

3. The examination and records unit (inter enterprise)

Explanation:

The students ICT units and lab works together by communicating with one another in terms of file transfer, content chat systems and temporal record I keeping and processing.

The departmental information system operates at the higher level as an enterprise because at this stage the users at the work stations can no longer have full access to the platform because it is redefined to accommodate academic and non academic staff who are very useful in managing the data content, as well as keeping the security of these content intact against any form of security threats.

The examination and records unit on the final and higher level is the home server for all information systems security, backup and archive and the communication level regarded as the inter enterprise units. It is the final resort point when every other means of information and record keeping becomes threatened. Hence it is seen as the collation, record keeping and transfer point between one enterprise or department to the other.

Which of the following investments would have the highest future value at the end of 10 years? Assume that the effective annual
LenaWriter [7]

Answer:

The investment that will have the highest future value is option b.

Explanation:

First lets suposse the effective annual rate is 10%  

a. Future value= $2,500  

c. First you must obtain the net present value of all cash flows with the formula attached, for example:  

NVP= ($250/(1+10%)^1)+($250/(1+10%^2)+($250/(1+10%^3)... and so on until year 10  

With the excel formula "NPV" you can calculate the net present value specifying the interest rate, the cash flows.  

The NPV= $1,536.14  

And then you calculate the future value of this answer with this formula:  

VF=VP(1+i)^n  

VF= $1,536.14*(1+10%)^10  

VF=$3,984.36  

b. If payments are due at the beginning of every year means that at year 0 you start with $250. You must calculate the NPV in this way  

NPV= $250+($250/(1+10%)^1)+ )+($250/(1+10%^2)+($250/(1+10%^3)... and so on until year 10  

NPV= $1,786,14

And then you calculate the future value of this answer:

VF= $1,786,14*(1+10%)^10  

VF=$4,632.79

d. First, you must convert the annual interest rate into semi-annually interest

10% Annually effective is 4,88% Semi-anually effective

NPV=$125+($125/(1+4,88%)^1)+ )+($125/(1+4,88%^2)+($125/(1+4,88%^3)... and so on until period 20

NPV=$1,698.75

And then you calculate the future value of this answer:

VF= $1,698 *(1+10%)^10  

VF=$4,405.37

The investment that will have the highest future value is option b.

What amount needs to be invested today at 6% simple interest in order to have $4000 in 2 years?
garri49 [273]
Data:
A (amount) = ?
P (Principal) = $ 4000
r (rate) = 6% → 0.06
t (time) = 2 years

Formula:
A = P(1+r*t)

Solving:
A = P(1+r*t)
A = 4000(1+0.06*2)
A = 4000(1+0.12)
A = 4000*1.12
\boxed{\boxed{A = \$\:4480}}\end{array}}\qquad\quad\checkmark

Household consumers are the most conspicuous audience in that most mass media advertising is directed at them. T/F
elena-14-01-66 [18.8K]

Answer:

The correct answer is True.

Explanation:

Local advertising is of capital importance, especially for those who want to spread their business in specific cities or geographic regions.  

With word of mouth advertising, you can surely get your business to reach different cities; but not at the speed that is required to recover the investment invested.

Businesses that have a local advertising plan will be able to bring their products and / or services to potential customers located in the target geographic area and increase their recognition as a local brand.

We are sure you have heard the following quotes; <em>"The best publicity is what satisfied customers do"</em> by Philip Kotler, and "What helps people helps business" by Leo Burnett

So why is local advertising important? Business owners have asked themselves this question for years, and the answer is really quite simple ...  To get attention, direct traffic to your business and close sales.
