Explanation:
A key is a single or combination of many attributes that enable us pull a row of data from a table. Keys are identifiers used to get data seamlessly from the database. A key can be a primary key, secondary key, control key, or super key. A super key is a key or set of attributes use to identify tuples in a database. It can contain extra attributes not necessary for uniquely identifying a database.
Answer:
For values when n<32 use fb(n) else use fa(n).
See explaination for details
Explanation:
Earlier when n=1 fa(n)=2000 while fb(n)=2. for n=2 fa(n)=2000*22 =2000*4=8000 while fb(n)=2*24=2*16=32. It is observed that fa(n) requires more time than fb(n) for small values.
Now, we will see when fb(n) crosses fa(n). This can happen only when fb(n) values equals or greater than fa(n)
therefore,
2000n2<=2n4
Solving equation we get n2>=1000 which can happen when n>=32.
So for values when n<32 use fb(n) else use fa(n)
Answer:
public class Invitation
{
private String hostname;
private String address;
public Invitation(String n, String a)
{ // constructor that accepts two strings.
hostname = n;
address = a;
}
public String getHostname()
{
return hostname;
}
public void setAddress(String a)
{
address = a;
}
public String invite(String guest)
{
return "Hello" +guest+ ", you are invited to my party at " +address+". "+hostname+".";
}
public Invitation(String host, String address)
{
this.address = address;
this.hostname = host;
}
}
Explanation:
The Java program defines a class called "Invitation". The class constructor has two string arguments or parameters for the host of the event and the address. The invite method is used to generate the string invite message with the name of the guest as the argument. Use the "setAddress" method to set a new location of the event and the "getHostname" to get the name of the event host.

Explanation:
<em>Reserve capacity</em> is the number of minutes that a new, fully charged battery can discharge continuously and maintain a terminal voltage equal to or greater than 1.75 volts per cell.
<em>An ampere-hour </em>is an electric charge unit and its abbreviation is Ah.
It measures the amount of electric charge flowing through a battery in the case that amount supplies a current of 1 amp for 1 hour.
