what type of clause must you always use with DEKETE or UPDATE to avoid inadvertently changing data elsewhere in the database​
Shkiper50 [21]

While you’re using the DELETE or UPDATE to change the data in any database like MySQL or ORACLE, the WHERE clause can be used to avoid inadvertently changing data everywhere.

<u>Explanation:</u>

The WHERE clause checks the condition and the changes mentioned by the DELETE or UPDATE command will be done if the condition is true. There are also other clauses like HAVING, IN which will have range either inclusive or exclusive.

It is also noted that in MySQL, there is a method called WorkBench which enables safe mode and doesn’t execute statements without the WHERE clause.

Find the inverse function of f(x)= 1+squareroot of 1+2x
Svetllana [295]

Answer:

Therefore the inverse function of  f(x)=1+\sqrt{1+2x} is \frac{x^2-2x}{2}

Explanation:

We need to find the inverse of function f(x)=1+\sqrt{1+2x}

Function Inverse definition :

\mathrm{If\:a\:function\:f\left(x\right)\:is\:mapping\:x\:to\:y,\:then\:the\:inverse\:functionof\:f\left(x\right)\:maps\:y\:back\:to\:x.}

y=1+\sqrt{1+2x}\mathrm{Interchange\:the\:variables}\:x\:\mathrm{and}\:y

x=1+\sqrt{1+2y}

\mathrm{Solve}\:x=1+\sqrt{1+2y}\:\mathrm{for}\:y

\mathrm{Subtract\:}1\mathrm{\:from\:both\:sides}

1+\sqrt{1+2y}-1=x-1

Simplify

\sqrt{1+2y}=x-1

\mathrm{Square\:both\:sides}

\left(\sqrt{1+2y}\right)^2=\left(x-1\right)^2

\mathrm{Expand\:}\left(\sqrt{1+2y}\right)^2:\quad 1+2y

\mathrm{Expand\:}\left(x-1\right)^2:\quad x^2-2x+1

1+2y=x^2-2x+1

\mathrm{Subtract\:}1\mathrm{\:from\:both\:sides}

1+2y-1=x^2-2x+1-1

\mathrm{Simplify}

2y=x^2-2x

\mathrm{Divide\:both\:sides\:by\:}2

\frac{2y}{2}=\frac{x^2}{2}-\frac{2x}{2}

\mathrm{Simplify}

y=\frac{x^2-2x}{2}

Therefore the inverse function of f(x)=1+\sqrt{1+2x} is \frac{x^2-2x}{2}

If you have defined a class named SavingsAccount with a public static data member named numberOfAccounts, and created a SavingsA
Anvisha [2.4K]

Answer:

numAccounts = SavingsAccount.numberOfAccounts

Explanation:

In object oriented programming, when you have created an object of class, you can create several instances (objects) from that class by referencing the className.classFeild. In this instance SavingsAccount is the class name and

numberOfAccounts is a feild (or data member). to create a new numAccount, we use the syntax as above in the answer

Fofino [41]

Answer:

Two advantages of the agile methods are:

  • The agile method require less documentation process as compared to waterfall model and saves maximum time and money. It basically reduces the efforts and the amount of work.
  • In agile method, there is always high customer satisfaction present. In agile method, it is easy to modify in the data as compared to the waterfall model. The customers and developers always interact with each other as the interaction is very important for the good results in the project.

Two disadvantages of the agile methods are:

  • For the large and complex projects, sometimes it is difficult to determine the requirements in the software development as projects are easily go off track.
  • There is less predictability and the projects are easily messed up if the projects requirement are not clear by the customer end.
