Most computers have three types of ports: serial, parallel, and USB. A serial port is a type of interface that connects a device to the system unit by transmitting data only one bit at a time. Serial ports usually connect devices that do not require fast data transmission rates, such as a mouse, keyboard, or modem.
Answer:
In C:
#include <stdio.h>
#include <math.h>
int main(){
float f0,r,temp;
r = pow(2.0,1.0/12);
printf("f0: "); scanf("%f", &f0);
temp = f0;
for(int i = 0; i<=4;i++){
f0 = f0 * pow(r,i);
printf("%.2lf ", f0);
f0 = temp; }
return 0;
}
Explanation:
This declares f0, r and temp as float
float f0,r,temp;
This initializes r to 2^(1/12)
r = pow(2.0,1.0/12);
This prompts the user for f0
printf("f0: "); scanf("%f", &f0);
This saves f0 in temp
temp = f0;
This iterates the number of keys from 0 to 4
for(int i = 0; i<=4;i++){
This calculates each key
f0 = f0 * pow(r,i);
This prints the key
printf("%.2lf ", f0);
This gets the initial value of f0
f0 = temp; }
return 0;

Answer:
The steps that Fatima needs to follow in-order to send an email on the Outlook include:
1. Open the Outlook application.

<em>After the message has been typed, a contact to whom the message is going to be sent to is selected before actually sending out the message by a click of a button.</em>
Answer:
Explanation:
Present value is the value in the present of a sum of money, in contrast to some future value it will have when it has been invested at compound interest.
It can be calculated using future value formula below
A = P(1+r/100)^n
where
A = Future value
P = Present value
r = Rate of interest
n = time period
Present Value = Value at Year 1 + Value at Year 4
Calculating Value at Year 1
A = $5,500
r = 8%
n = 1
From A = P(1+r/100)^n ; Make P the subject of formula
P = A ÷ (1 + r/100)^n
Substitute in values
P = $5,500 ÷ (1 + 8/100)^1
P = $5,500 ÷ (1 + 0.08)
P = $5,500/1.08
P = $5092.5925926
P = $5092.59 ----
Present Value at Year 1 = $5092.59
Calculating Value at Year 4
A = $5,000
r = 8%
n = 1
From A = P(1+r/100)^n ; Make P the subject of formula
P = A ÷ (1 + r/100)^n
Substitute in values
P = $5,000 ÷ (1 + 8/100)⁴
P = $5,000 ÷ (1 + 0.08)⁴
P = $5,000/1.08⁴
P = $3675.149263982267
P = $3675.15 ----
Present Value at Year 4 = $3675.15
Present Value = Value at Year 1 + Value at Year 4
Substitute each value
Present Value = $5092.59 + $3675.15
Present Value = $8,767.74
